SUMMARY OF CHANGES
This manual combines AFMANs 65-506, Economic Analysis, and 65-510, Business Case Analysis
Procedures. This manual clarifies that economic analysis is both an analytical approach to
decision-making and one of many products resulting from the analytical approach. This manual
includes a clarification that all Comparative Analysis products (e.g., Economic Analysis (EA),
Cost Benefit Analysis, Analysis of Alternatives (AoA), Business Case Analysis (BCA)) fit under
the umbrella of the economic analysis approach and are subject to this instruction (consistent with
Department of Defense Instruction (DoDI) 7041.03, Economic Analysis for Decision Making).
This manual clarifies that the level of rigor in an economic analysis will vary with multiple factors
(e.g., maturity of the project, dollar value of the project)
This manual updated and added detail to the elements that must be addressed as part of the
economic analysis approach. This manual includes an economic analysis process overview with
tips on how to get started.
This AFMAN revised the chapter contents to more closely align with the elements that must be
included in a comparative analysis. Chapter 2 was expanded to include: Background, Scope, Facts
and Ground Rules. The Objective and Assumptions sections of Chapter 2 were clarified.
This manual made the instruction on alternatives into its own Chapter (Chapter 3). The Chapter
expands upon the previous explanation of alternatives.
This manual expands the Chapter on cost (Chapter 4) to include more information on building the
cost analysis. Chapter 4 includes a table to explain the different purposes of cost estimates and
provide the context of how building the cost estimates for a comparative analysis differs from other
cost estimates. Chapter 4 explains the incremental cost concept. Chapter 4 includes the basic steps
for building a cost estimate and a brief description of a few common estimating techniques.
Chapter 4 moved topics such as terminal value, discount factors, present value, and Uniform
Annual Cost method to the section on “Other Considerations in the Cost Analysis.”
The chapter on benefits (Chapter 5) now includes more information on building a benefit analysis.
Chapter 5 added flexibility to allow for benefits to be expressed as either a narrative or on an
ordinal scale. Chapter 5 includes more detail on developing a benefit hierarchy (if needed) and
weighting benefits. Chapter 5 includes examples of benefit analysis summary tables.
The chapter on Uncertainty Analysis (sensitivity and risk analysis) (Chapter 6) now includes more
information on building risk and sensitivity analyses. Chapter 7 now includes comparison of
alternatives, providing results, documentation and post analysis activities. This chapter includes a
requirement to provide an interpretation of results. The post analysis activities include such topics
as: an implementation plan and stakeholder analysis. This manual moved special analyses to the
attachments and expanded them. This manual updated the attachments to include a section on the
Clinger-Cohen Act analyses (Attachment 13) and a section on Real Property Construction and
Repair analyses (Attachment 11).
AFMAN65-506 6 SEPTEMBER 2019 3
This manual moved the Economic Impact Analysis (EIA) to Attachment 12. The attachment was
changed to adapt to the new source of multipliers. This update includes references to a new Excel
Tool that implements the new method for performing the economic impact analysis.
This manual updates the form for submitting a waiver and the format for the Executive Summary.
This manual added information on the certification process that includes consideration of recent
changes to Air Force organizations. This manual also updated the certificate of satisfactory
economic analysis.
This manual updated the Economic Analysis Review Guide (Attachment 6), and the Preparer’s
Guides (Attachment 5). This manual updated the formulas for Factors and financial Indicators
(Attachment 7).
This manual updates the sample formats for summary of costs (Format A and Format A-1)
(Attachment 8). The update clarifies which costs should be included when using the Uniform
Annual Cost Method versus the Terminal Value Method.

Chapter 1
ECONOMIC ANALYSIS PRINCIPLES
1.1. Economic Analysis Background
1.1.1. Economic analysis is a systematic approach to decide how to use scarce resources to
meet a given objective. Properly using the economic analysis approach yields an impartial
analysis of competing alternatives to meet an objective, and weighs the costs, and benefits and
uncertainty for each alternative. The economic analysis approach does not replace the
judgment of a decision maker, but rather provides an analytic and uniform foundation upon
which sound decisions can be made.
1.1.2. Analyses that include costs and benefits to support decision making are performed under
a variety of names (e.g., Cost Benefit Analysis, Analysis of Alternatives, Economic Analysis,
Business Case Analyses). Any analysis that includes cost benefit and uncertainty
considerations fits under the definition of “economic analysis” even though not specifically
titled as such.
1.1.3. For the remainder of this manual, all analyses resulting from implementing the
economic analysis approach will be referred to as “comparative analyses” or simply as
“analyses” unless referring to a specific product whose name has been directed at a higher level
(e.g., Product Support Business Case Analysis, Military Construction Economic Analysis).
The conceptual approach to decision-making will be referred to as economic analysis to remain
consistent with DoDI 7041.03.
Figure 1.1. Economic Analysis Approach and Comparative Analysis.
1.1.4. The economic analysis approach considers all significant anticipated effects of a
decision across the entire organization, not just the financial ones. It also assesses the
likelihood that those effects will occur as anticipated (i.e., uncertainty/risk).
8 AFMAN65-506 6 SEPTEMBER 2019
1.1.5. Programs, projects, and initiatives evaluated using the economic analysis approach may
include any significant decision that leadership is contemplating. The following is a sample
(not all-inclusive) list of programs and situations for which the economic analysis approach
can be used to assist in decision making:
1.1.5.1. Military construction (MILCON), military family housing and facility repair.
1.1.5.2. Tradeoffs between force structures, force size, modernization, fuel/energy
consumption, and readiness.
1.1.5.3. Manpower analysis.
1.1.5.4. Projects to mechanize, automate, prevent obsolescence, improve workflow and
layout, or increase capacity.
1.1.5.5. Acquiring, repairing, supporting, modifying or replacing weapon systems,
information systems or information technology.
1.1.5.6. Acquiring or upgrading equipment to reduce operating and support costs.
1.1.5.7. Lease or purchase of general purpose real property, such as office buildings,
warehouses, and associated land.
1.1.5.8. Consolidating facilities, such as warehouses, maintenance and storage depots, and
repair activities to decrease cost for any reason or to add to mission effectiveness.
1.1.5.9. Business process improvement (business reengineering).
1.2. Elements of the Economic Analysis Approach.
1.2.1. The economic analysis approach will be driven by the context around the decision.
Some of the drivers include: the stage a program or project is in its life cycle, the level of
resources consumed in the project, the level of visibility, and the scope/significance of the
objective. As a result, analysis may require a tailored approach to fit the project. Tailoring
could include abbreviating some elements of the analysis, or going into greater depth on some
elements, but in almost all cases the basic elements in 1.2.2 need to be included in some
manner.
1.2.2. Unless otherwise stated, the elements below must be included when applying the
economic analysis approach. (T-2).
1.2.2.1. Background/Objective/Scope These areas provide the programmatic foundation
upon which the analysis is built. The background provides the context for the analysis while
the objective and scope define what the project or program under study seeks to attain.
1.2.2.2. Facts/Ground Rules/Assumptions These areas identify parameters significant to
the analysis. Facts are key known parameters that are significant to the analysis. Ground
rules are general principles (often directive in nature) that provide bounds for the analysis.
Assumptions are key parameters where the values and circumstances must be estimated
because reliable knowledge is lacking. Without assumptions, analytical models would not
be able to produce useful conclusions.
1.2.2.3. Alternatives Solution sets evaluated to meet the objective.
1.2.2.4. Cost Analysis Analysis of monetary costs/savings/revenue effects by alternative.
AFMAN65-506 6 SEPTEMBER 2019 9
1.2.2.5. Benefit Analysis Analysis of non-monetary attributes of each alternative.
1.2.2.6. Uncertainty Analysis
1.2.2.6.1. Sensitivity Analysis Test of the assumptions to see how the results are
impacted.
1.2.2.6.2. Risk Analysis Analysis of risks by alternative.
1.2.2.7. Summary and Comparison of Alternatives Evaluation and comparison of the
alternatives and discussion of key findings in the analysis.
1.2.2.8. This list does not preclude an analyst from incorporating other relevant
information when using the economic analysis approach to complete a comparative
analysis.
1.2.3. The resulting comparative analysis product will be formatted with the following
sections: a certification (when required by AFI 65-501, para 1.7), an executive summary, the
analysis itself, supporting appendices and supporting documentation. (T-2).
1.3. Applying the Economic Analysis Approach: Overview.
1.3.1. Sources of guidance and support
1.3.1.1. When the need for a comparative analysis is identified, one of the first questions
is where to get guidance and support. Figure 1.2 illustrates primary support organizations
for acquisition-related and all other analyses.
1.3.1.2. For Major Command (MAJCOM) and Installation organizations (outside of
weapon system acquisition), the Air Force Installation and Mission Support Center
Resource Management Cost Division (formerly the Financial Management Center of
Expertise) or MAJCOM Cost Staff are the primary sources of guidance and support.
1.3.1.2.1. The scope and type of project may affect which organization ultimately
assists with a comparative analysis project.
1.3.1.2.2. As an example, while an Installation Financial Office should contact the Air
Force Installation and Mission Support Center Resource Management Cost Division
for support with an analysis, that analysis may be passed to the Air Force Economics
and Business Management Division (SAF/FMCE) for support if its scope crosses
multiple MAJCOMs.
1.3.1.3. For Headquarters Air Force level organizations, SAF/FMCE is the primary source
of guidance and support.
1.3.1.4. For weapon system acquisition programs on the Acquisition Master List or other
Acquisition designations (e.g., Fiscal Year (FY) 17 National Defense Authorization Act
section 804 programs), the primary source of guidance and support is the program’s Center
Cost staff.
1.3.1.5. For acquisition programs which are not included under paragraph 1.3.1.4 above,
the primary sources of guidance and support are SAF/FMCE, MAJCOM Financial
Management staff, or Center Cost staff.
10 AFMAN65-506 6 SEPTEMBER 2019
Figure 1.2. Comparative Analysis Support.
1.3.2. Build a Plan and Schedule
1.3.2.1. Build a plan for the analysis. Identify key personnel including the decision maker,
functional experts, and other analysts and support. Confirm the objective and scope of the
analysis and how it will be used. Identify sources for cost, performance, capability, and
other benefit and uncertainty data, etc., as applicable. Verify the higher-level review and
certification requirements. Identify the specific deliverables required.
1.3.2.1.1. Depending on the scope and the time available, hold a kickoff meeting with
key stakeholders to determine the plan and schedule.
1.3.2.1.2. The elements in this section are important to consider even for an analysis
which will not be formalized.
1.3.2.2. Timeliness is important in a comparative analysis. Particularly when there is a
hard suspense (e.g., Program Objective Memorandum build), it is important to develop a
schedule that meets the decision-maker’s timeline. If the analysis is completed too late for
the decision, it will not have an impact. When the suspense is softer, the analyst may be
able to negotiate the schedule in order to provide a more robust analysis. This is a balance
that will need to be addressed early in the program.
1.3.3. Foundation - Work with the requirement owner to develop foundational elements.
1.3.3.1. The foundational elements include: background, objective, scope, facts,
assumptions, and ground rules.
1.3.3.2. These foundational elements guide the remainder of the estimate. It is important
to understand that while they guide subsequent analysis, they can be revisited and updated
if the update would lead to a more valuable analysis. In particular, the assumptions should
be revalidated and updated during the analysis process.
AFMAN65-506 6 SEPTEMBER 2019 11
Figure 1.3. Foundational Elements.
1.3.4. Alternatives After these initial steps, the analyst will have the foundation needed to
develop a set of alternatives that would satisfy the objective. Chapter 3 provides more details
on developing an appropriate set of alternatives.
1.3.5. Cost/Benefits/Uncertainty The foundation, together with the alternatives, will enable
the analyst to begin building the cost analysis, benefit analysis, and uncertainty analysis. As
part of the uncertainty analysis, the analyst should test the strength of the results using
sensitivity analyses and may assess risk. See Chapters 4, 5, and 6 for more detailed guidance
on cost analysis, benefit analysis, and uncertainty analysis.
Figure 1.4. Data Collection.
1.3.6. Summary and Comparison of Alternatives With completed cost, benefit, and
uncertainty analyses, the analyst will have sufficient information to compare the alternatives.
In addition to comparing the alternatives, the analyst interprets the results. Chapter 7 provides
additional information on this step.
1.3.7. Documentation/Report The analyst will finish the comparative analysis product (i.e.,
the documentation for the economic analysis) for delivery to the decision maker. (T-2). More
information on documentation is provided in Chapter 7.
1.4. Roles and Responsibilities. For a complete listing of the Roles and Responsibilities of
developing an Economic Analysis, see section 1.4 of AFI 65-501. Roles and Responsibilities for
certification are contained in Attachment A3 of this manual.
12 AFMAN65-506 6 SEPTEMBER 2019
Chapter 2
FOUNDATIONAL ELEMENTS: BACKGROUND, OBJECTIVE, SCOPE, FACTS,
GROUND RULES AND ASSUMPTIONS
2.1. Background. The background provides a context for the analysis. The background should
be concise. Some examples of items to include in background context are:
2.1.1. A brief project/program history, technical description (if applicable), and current state
of the project/program. For a complex program, the technical description could include
information about the maturity of the concepts and technology.
2.1.2. A brief synopsis of why the analysis is needed (e.g., problem that is being addressed,
legislative compliance, Command directed).
2.1.3. Key milestone dates for the program, initiative, project, etc. that affect the timing or
constrain the scope of the analysis.
2.1.4. The intended audience for the analysis.
2.1.5. Timeframe for the analysis.
2.1.6. Any other relevant information on how the analysis will be used (budgeting,
contracting, etc.).
2.2. Objective of the Comparative Analysis. The objective of the comparative analysis is the
purpose for which the analysis is being performed. When doing the analysis, the analyst should
frequently reference the objective to ensure the analysis remains consistent with the purpose.
2.2.1. The objective statement should clearly and succinctly define and quantify, to the extent
possible, what the project or program under study seeks to attain (e.g., obtain sufficient
workspace for 200 people arriving on base as a result of gaining a new mission). It should state
the goal or objective (i.e., mission or mission support requirement) to be met by the alternatives
under study.
2.2.2. The objective should address the true problem to be solved. For example, do not limit
the objective to insufficient manpower at the gate to check IDs when the problem to be solved
is long lines (which may have a variety of solutions).
2.2.3. The objective should be stated broadly enough that it can be met by multiple alternatives
and not in a way that favors or pre-supposes one particular alternative. A narrowed objective
can sometimes introduce what is called pre-selection bias.
2.2.4. The objective statement should reflect the purpose of the project or program that is being
analyzed. Conversely, it should not be a statement of the objective of the analysis.
AFMAN65-506 6 SEPTEMBER 2019 13
Figure 2.1. Objective.
2.3. Scope.
2.3.1. The scope describes the content that is included in the analysis and the content that is
excluded from the analysis. In assessing the scope, the analyst will need to determine the level
of the objective (e.g., Society, Federal Government, Defense Department, Air Force,
MAJCOM, Installation, Portfolio, or Program). The scope is a focusing mechanism for the
analysis.
2.3.2. Be cautious of narrowing the scope unnecessarily. It is important to consider costs and
benefits, including potential second and third order effects, experienced by all affected
organizations.
2.3.3. Be cautious also of having a scope that is too broad or the analysis may become
unwieldy.
2.4. Parameters of the Analysis (Facts/Ground Rules/Assumptions). All parameters must be
explicitly stated. (T-2).
2.4.1. Facts - Facts are key parameters that will be significant to the analysis and for which
the value is known.
2.4.1.1. Facts may include information about factors that may be relevant for an analysis.
For example, in a vehicle lease versus buy analysis, a fact may be that there are currently
excess vehicles in the inventory.
2.4.1.2. An analyst should include important facts in the background of the analysis.
2.4.2. Ground Rules - Ground rules are general principles that provide bounds for the analysis.
2.4.2.1. Some common examples of ground rules include: period of analysis and type of
dollar used (base-year, then-year, and constant-year).
2.4.2.2. Ground rules can also involve the scope of the analysis. Certain areas can be
excluded from the analysis by ground rule. When doing so, the analyst should have a
rationale for the exclusion.
2.4.3. Assumptions - Assumptions are key parameters where the values and circumstances
must be estimated because their values depend on future events or there is a lack reliable
knowledge.
2.4.3.1. Only assumptions that are necessary and reasonable should be included in an
analysis. The reasonableness and validity of assumptions, as well as the need for new
assumptions, should be periodically re-assessed throughout the course of the analysis.
14 AFMAN65-506 6 SEPTEMBER 2019
2.4.3.2. Avoid making assumptions where facts should be used.
2.4.3.3. Assumptions should not be made for the convenience of the analyst or one of the
stakeholders, or to unfairly favor one alternative over another.
2.4.3.4. The analyst should avoid treating assumptions as facts (e.g., past workload is a
fact, projecting that workload into the future is an assumption). Any such assumptions
should be explicitly stated in the Assumptions section of the analysis. Sometimes current
facts can be used as a foundation for an assumption. For example, the fact that there are
currently excess vehicles may be used to assume that the excess will persist in future years.
2.4.3.5. There are times when assumptions can appropriately narrow the scope of an
analysis to manageable proportions, but they should not unduly constrain the analysis by
eliminating otherwise reasonable alternatives.
2.4.3.6. Assumptions are one way to handle uncertainty in an analysis. A Sensitivity
Analysis must be performed to test the effect that major assumptions have on analysis
results. (T-1).
2.4.3.7. Examples of areas where assumptions are commonly made include: operations,
organization, facilities, schedule, discount factors, inflation factors, manpower factors,
production rates, utilization rates, workload, requirements and changes to requirements,
estimated economic lives, future events, efficiency factors and reliability rates.
AFMAN65-506 6 SEPTEMBER 2019 15
Chapter 3
ALTERNATIVES
3.1. Overview.
3.1.1. Alternatives are reasonable courses of action to attain the stated objective.
3.1.2. In developing the analysis, the analyst will consider (identify and discuss) all reasonable
alternatives. All alternatives that are reasonable and feasible shall be fully analyzed. (T-2).
3.2. Baseline/Status Quo
3.2.1. Analyses almost always include a baseline alternative by which all other alternatives
are compared. Typically, the baseline is the Status Quo alternative. The baseline describes
how the program or process under study currently performs with respect to the objective.
3.2.2. If the analysis is on a new initiative, there may not be a baseline to measure against. In
some cases, the Status Quo may be infeasible or unreasonable. (See paragraph 3.3.4) In those
cases, another alternative, or modified status quo, is commonly set as the baseline in order to
have a comparison point for the analysis.
3.3. Reasonableness and Feasibility
3.3.1. The analyst shall address all reasonable alternatives. (T-2).
3.3.2. Each reasonable alternative shall be evaluated for feasibility. (T-2). Alternatives that
are reasonable and feasible shall be fully analyzed. (T-2).
3.3.3. If any reasonable alternative is deemed infeasible, the reasons shall be fully explained
in this section. (T-2). After documenting reasonable alternatives that are infeasible, the
infeasible alternatives do not need to be considered any further in the analysis. Documenting
reasonable alternatives that are infeasible alternatives informs readers and reviewers that all
reasonable alternatives were considered, and provides the rationale for deeming some
alternatives as infeasible. If there are alternatives that are feasible, but excluded for some other
reason, the rationale for exclusion must be explained in this section (e.g., see paragraph 3.4).
(T-2).
3.3.4. Care must be taken to ensure a difference in capability or other benefits is not construed
to mean infeasibility. Infeasibility means an alternative does not satisfy the required minimum
level of acceptable performance (see paragraph 5.4.7.1.2). Mere differences in capabilities
should be accounted for in the Benefits section. In the analysis, the decision maker can weigh
the difference in benefits against any cost differences. One common pitfall is to define the
objective too narrowly (see Chapter 2) such that the Status Quo cannot meet the requirement.
For example, the objective may be defined too narrowly such that a new business system is the
only alternative to meet that objective. Instead, a properly defined objective would allow for
the status quo, or a modification to the status quo to be feasible, but not provide as many
benefits.

AFMAN65-506 6 SEPTEMBER 2019 17
Figure 3.2. Reasonable and Feasible Notional Illustration.
3.4. Completeness
3.4.1. Be thorough when developing alternatives. Make sure all reasonable alternatives are
included. It is essential to leverage input from key personnel identified in section 1.3.2.1 to
both identify and determine the reasonableness/feasibility of alternatives.
3.4.2. Use inputs from experts, critics, and supporters of various viewpoints. Be willing to
use external parties such as: the commercial sector, Congressional reports, or academia.
3.4.3. Consider combinations of systems or approaches and solutions that involve outside
agencies or organizations (e.g., community partnerships).
3.4.4. While considering a full range of alternatives, if the number of alternatives is too great
to be manageable, screen out the most unlikely in order to keep the number of alternatives to
a manageable level. Provide details regarding the down select methodology used.
3.4.5. Analysis is iterative, and as such, the set of alternatives may not be static. As the
analysis progresses and new information becomes available, be open to expanding or reducing
the set of alternatives.
3.5. Describing Alternatives
3.5.1. Fully explain what each alternative involves, especially those aspects that are likely to
drive costs and benefits.
3.5.1.1. Explain how each process or procedure would work, what personnel, equipment,
or facilities would be required, and what other changes from the Status Quo or baseline
would be involved.
18 AFMAN65-506 6 SEPTEMBER 2019
3.5.1.2. Each alternative should be fully described, to enable someone completely
unfamiliar with the program to fully understand what would be involved in its
implementation.
3.5.1.3. At a minimum, the description shall include attributes that will result in costs to
the government. (T-2).
3.5.2. When describing the alternatives, the analyst should not include conclusions about the
relative merit of the alternatives.

Chapter 4
COST ANALYSIS
4.1. Overview - Cost Analysis
4.1.1. Cost estimates/analyses support many different types of decisions and activities. The
cost estimates in a comparative analysis are for the purpose of comparing the incremental costs
that would be incurred by the decision over the period of the analysis.
4.1.2. The cost analysis includes those items traditionally understood to be monetary costs,
revenues, and savings. As such, the cost analysis is really an analysis of monetary impacts
both positive and negative.
4.1.3. Cost methodologies must be thoroughly documented so the analysis can be replicated
if necessary. (T-2).
4.2. Purpose of Cost Analysis
4.2.1. The purpose of a cost analysis in a comparative analysis is different from its purpose in
many other uses. Key areas where the cost analysis of comparative analyses may differ from
other analyses include: the use of only incremental costs, the treatment of sunk costs, possibly
varying periods of analysis and treatment of revenue and savings (sometimes referred to as
monetary benefits). Cost analyses developed for another purpose need to be adjusted to
account for the difference in purpose in a comparative analysis. Some prominent purposes for
cost analyses and how they impact the cost calculations and presentation can be found in Table
4.1
Table 4.1. Cost and Purpose.
20 AFMAN65-506 6 SEPTEMBER 2019
4.2.2. For comparative analyses, the cost analyses for the alternatives will be compared using
dollars that have been discounted to present value. (T-2). This allows for an appropriate
comparison of investment costs, typically occurring early in the period of analysis, with
recurring costs which typically occur later in the period of analysis. The year selected for
present value calculations is the first year investment funds will be required or the first year of
the analysis. This is commonly referred to as the base year of the program or project.
4.2.3. The estimate includes all costs incremental to the implementation of each
alternative.
4.2.3.1. Include incremental costs for those portions of the life-cycle covered by the period
of analysis. Include the cost of design, development, procurement, operation, support, and
disposal or residual value, as appropriate.
4.2.3.2. A comparative analysis normally includes all costs to the US government within
the scope of the analysis, not simply those incurred by the function under study. The scope
of the analysis should not be artificially drawn to exclude costs outside the Air Force.
While thorough cost analyses is the goal, it may not be possible to understand and capture
all of the effects a decision could have on other government agencies. The analyst will
have to use judgement to determine the extent to which costs outside the Air Force are
captured.
4.2.4. The cost analyses in a comparative analysis will only include costs for which funds have
not yet been expended or irrevocably committed. (T-2). In other words, sunk costs are not
included in a comparative analysis.
4.3. Basic Steps for the Cost Analysis
4.3.1. These steps are intended as a basic guide to developing cost analyses that fit within
economic analyses and the framework of this manual. These steps are not intended to be a
comprehensive guide to cost analysis. There are additional materials that provide more in-
depth guidance. Examples of additional materials include on-line Defense Acquisition
University courses (e.g., BCF130 Fundamentals of Cost Analysis), the Government
Accountability Office Cost Estimating and Assessment Guide, and the Government
Accountability Office Schedule Assessments Guide.
4.3.2. Review Foundational Elements
4.3.2.1. The cost analysis should be based on the objective statement and scope.
4.3.2.2. Reviewing the foundational elements will focus the analysis on the decision to be
made.
4.3.3. Build Cost Element Structure
4.3.3.1. The cost element structure is the framework for building the estimate.
4.3.3.1.1. The cost element structure is a hierarchical breakdown of the program or
project being estimated. Costs are estimated at the lowest level of the cost element
structure. The cost element structure (and the estimating technique used) will be
dependent on the data that is available. At times, the level of detail in the structure will
be limited because the available data better support a higher level estimating approach.
AFMAN65-506 6 SEPTEMBER 2019 21
4.3.3.1.2. It is important to understand the cost behavior of the cost elements when
building the cost element structure. For example, recurring and non-recurring should
not be included in the same cost element because the costs behave differently.
4.3.3.2. For a comparative analysis, each alternative may require different cost element
structures.
4.3.3.3. In many comparative analyses, a cost estimate for a particular alternative may
already exist. The analyst has to review the cost element structures across alternatives to
ensure the content included for each alternative is comparable.
Figure 4.1. Example - Build New Facility Cost Element Structure.
4.3.3.4. The latest version of the Military Standard 881 (MIL-STD-881) contains weapon
system related examples of work breakdown structures. Similarly, the Cost Analysis and
Program Evaluation Operating and Support Cost-Estimating Guide contains a cost element
structure for operations and support of weapon systems. While MIL-STD 881 and the Cost
Analysis and Program Evaluation Guide provide excellent examples, they may not fit the
circumstances of the alternative being estimated. As a result, the analyst may have to build
a new cost element structure to fit the level of detail and unique circumstances of their
estimate. Figure 4.1 contains cost elements that may be used in a facility construction cost
element structure.
4.3.4. Select Estimating Technique will likely vary across cost elements
22 AFMAN65-506 6 SEPTEMBER 2019
4.3.4.1. The estimating technique will depend on the data available.
4.3.4.2. The estimating technique can be different for each alternative and even each cost
element.
4.3.4.3. It is critical that the analyst ensure that the alternatives remain comparable even
when a unique estimating technique is selected for each alternative.
4.3.4.3.1. For example, an analogy-based estimate for one alternative may include a
computer hardware refresh because it was included in the analogous program.
Conversely, if another alternative was using an engineering estimate, the computer
hardware refresh may need to be estimated separately in a different cost element.
4.3.4.3.2. As another example, extrapolation of actuals is a common approach for the
Status Quo alternatives; while actuals are not available for new alternatives, the analyst
may employ a parametric model to estimate the costs of an alternative. Caution should
be taken to ensure that what is included in the actuals is comparable to the content of
the parametric model to avoid biasing the analysis in favor of one alternative due to
missing or overstated costs.
4.3.4.4. There are a variety of techniques that can be used to build the estimate. A list and
brief description of some common techniques are provided below. Training courses are
available with additional information on the estimating techniques. An example on-line
training course from Defense Acquisition University is BCF130 (Fundamentals of Cost
Analysis). The Government Accountability Office Cost Estimating and Assessment Guide
is also a valuable source for information on cost estimating techniques.
4.3.4.4.1. Analogy Under this technique, the analyst estimates cost based on
historical data from a similar program. When using an analogy, the analyst should
include a technical comparison between the existing and proposed systems in order to
account for the difference between the analogous program and the program being
estimated.
4.3.4.4.2. Engineering (also called grass roots and bottom up) Under this technique,
the analyst calculates labor and materials from the most detailed level of the program
and aggregates those costs to get the total program cost. While it is very detailed, this
method is generally more time intensive and includes a risk of missing some aspect of
the program when building the estimate.
4.3.4.4.3. Parametric Under this technique, the analyst estimates cost based on
historical data from multiple past programs. Parametric estimates use cost estimating
relationships that correlate programmatic characteristics (e.g., size, lines of code,
weight) with cost. These cost estimating relationships can be developed either singly,
or as part of a software package. The analyst estimates cost using the programmatic
characteristics of the proposed program.
4.3.4.4.4. Extrapolation of Actuals Under this technique, the analyst estimates future
costs based on historical data from the program being estimated. This technique can
only be used for programs that are on-going.
AFMAN65-506 6 SEPTEMBER 2019 23
4.3.4.4.5. Catalog Prices/Vendor Quote This technique is simply obtaining quotes
from a vendor or catalog. This is commonly used to obtain a lease price in a
lease/purchase analysis. It is important that the analyst understand exactly what is
included in the vendor quote so that a proper comparison can be made across
alternatives. This technique works best with commercially available products where
multiple quotes can be obtained.
4.3.4.4.6. Factors This technique is essentially a subset of the parametric technique
or the analogy technique. Essentially, a single factor can result from a cost estimating
relationship (e.g., Supervision Inspection and Overhead Cost as a percentage of
Construction Cost).
4.3.5. Collect Cost Data and Apply Estimating Techniques
4.3.5.1. Data collection should occur as early as possible because it may be difficult to
find good data. Similarly, data collection and the selection of estimating techniques is
normally be done simultaneously because the estimating technique depends on available
data.
4.3.5.2. As data is collected, use the selected estimating techniques to begin populating the
cost estimate.
4.3.5.3. Document completely the source/origin of all data collected. (T-2).
4.3.6. Time Phasing, Escalation, Inflation, and Discounting
4.3.6.1. Time phasing the estimate is ensuring that costs are placed in the year the cost will
be incurred. Proper time phasing requires that the costs be escalated to the appropriate year
using a price escalation index so that the estimate is in then-year dollars. The price
escalation index used must be documented. (T-2).
4.3.6.2. After the estimate is time phased and calculated in then-year dollars, the estimate
must be converted to present value dollars. (T-2). This can be done one of two ways. The
first way is to apply the nominal discount rate to the then-year dollars. The second way is
to first convert the then-year dollars to constant year dollars using an inflation index and
then use the real discount rate to convert the estimate to present value. Whichever method
is selected, the calculation must be documented. (T-2).
4.3.6.3. For detailed instructions on escalation and inflation, consult AFMAN 65-502,
Inflation.
4.4. Components of a Cost Analysis
4.4.1. It is important to understand what should be included in the cost analysis section of an
economic analysis. The cost analysis should only include the costs, savings and revenue
required as a result of selecting the alternative.
4.4.2. Sunk cost
4.4.2.1. Any cost incurred in the past, to include future costs that have been irrevocably
committed. An example of a future cost that has been irrevocably committed would be
work on a contract that has been performed, but not yet paid.
24 AFMAN65-506 6 SEPTEMBER 2019
4.4.2.2. Such costs have no bearing on any decision to be made, and so should not be
included in a comparative analysis. Life cycle cost estimates will need to be adjusted to
remove sunk costs when being used for comparative analyses. (T-2).
4.4.3. Wash costs (also called Common costs)
4.4.3.1. Any cost that will be incurred identically across alternatives. Wash costs are
optional to include, but should be treated the same across alternatives (i.e., either included
or excluded) and documented completely.
4.4.3.2. Wash costs may be excluded for simplicity. This is sometimes called a “delta
estimate.”
4.4.3.3. Wash costs may be included so the decision-maker can get a full appreciation of
the magnitude of the cost of an alternative.
4.4.3.4. It may be necessary to include wash costs when using some estimating techniques
and data sources.
4.4.4. Average cost
4.4.4.1. The average cost is the total cost divided by the number of units that make up the
total.
4.4.4.2. When using these types of averages, make sure they are appropriate for the
analysis and will not bias the results. For example, the cost of a Captain in AFI 65-503 is
an average expected cost of all the Captains in the Air Force. If the study only involves
one location, it may be better to use the local Basic Allowance for Housing cost instead of
the average Basic Allowance for Housing listed in AFI 65-503.
4.4.5. Non-recurring cost
4.4.5.1. One-time costs or costs that are not expected to continue beyond the investment
phase. These costs usually take the form of initial capital or other unique expenditures.
4.4.5.2. Types of non-recurring costs include:
4.4.5.2.1. Research and Development Costs
4.4.5.2.2. Investment costs. These are costs associated with the acquisition of
equipment, real property, nonrecurring services, nonrecurring operations and start- up
costs, and other one-time outlays.
4.4.5.2.3. Costs of acquisition, rehabilitation, or modification of assets such as: land,
buildings, machinery, equipment, furniture and one-time computer software costs.
4.4.5.2.4. Temporary facilities/swing space.
4.4.5.2.5. Costs of plant rearrangement and tooling associated with the project.
4.4.5.2.6. Nonrecurring services received from others, both internal and external to the
Air Force.
4.4.5.2.7. Cost to cancel or terminate any existing arrangement that would result if a
different alternative were implemented.
4.4.6. Recurring cost
AFMAN65-506 6 SEPTEMBER 2019 25
4.4.6.1. Recurring costs are cost that are incurred repeatedly.
4.4.6.2. Types of recurring costs include:
4.4.6.2.1. Annual recurring cost: A cost incurred every year (e.g., membership dues).
Recurring costs many times occur at time intervals of less than one year (e.g., utilities).
Commonly these costs are aggregated and treated as annual recurring costs.
4.4.6.2.2. Periodic recurring cost: A cost incurred in a period greater than one year
long, like Programmed Depot Maintenance, or replacement of heating, ventilation and
air conditioning equipment that may be replaced every 20 years.
4.4.7. Fuel/Energy Costs: The fully burdened cost of delivered energy shall be used in
analyses conducted for all Department of Defense tactical systems with end items that create
a demand for energy. (T-0). Be sure to only include those costs that are incremental to a
decision.
4.4.8. Induced Costs: Induced costs are those costs that the execution of a given project or
program alternative impose on another Air Force or government program. For example, if a
proposal to move an activity into facilities currently occupied by a second activity causes
expenditures by the second activity for real property acquisition or improvement, then those
expenditures are induced costs that should be taken into account in the decision to move the
first activity.
4.4.9. Costs incurred in foreign currency: The cost analysis portion of comparative analyses
will be performed in United States dollars. (T-1). See attachment 14 for additional details.
4.4.10. Opportunity cost
4.4.10.1. Opportunity cost is the cost of a resource measured in terms of its value in the
best alternate use. One way opportunity costs are accounted for in comparative analyses
is through the discount rate. Some projects may experience additional opportunity costs
specific to that project.
4.4.10.2. For example, the value of an existing asset may be included when there is an
opportunity cost associated with the asset. As an example, assume a piece of equipment
valued at $1,000 is being used in the Status Quo process. In the process for Alternative 1
the equipment is not needed; however, the same equipment was programmed to be
purchased by another organization. This other organization will be able to forego the
purchase and use the existing equipment if Alternative 1 is selected. In this case, the
equipment could be counted as a negative cost in the cost analysis for Alternative 1 because
the other organization now does not need to purchase the equipment.
4.4.11. Depreciation expense.
4.4.11.1. Depreciation accounts for the gradual consumption of capital goods and
resources over time. A common use is to allow business to "recover" investment in capital
goods through tax benefits.
26 AFMAN65-506 6 SEPTEMBER 2019
4.4.11.2. Normally, depreciation will not be included as a cost in an Air Force economic
analysis since it would double-count expenses (i.e., the acquisition cost of assets are
entered when the asset is acquired). However, depreciation procedures can be used to
estimate terminal or residual values. Depreciation may be a consideration in commercial
lease versus buy alternatives if it provides extraordinary tax benefits to the lessor that are
a cost to the Treasury.
4.4.12. Savings
4.4.12.1. Savings are not typically identified as a separate cost element. Instead, they are
reflected as the reduced cost of an alternative.
4.4.12.1.1. For example, if four people are required for a task in Alternative 2 instead
of the five required for status quo, the analyst would include the cost of four people for
Alternative 2. This will show up as a lower cost (savings) for that alternative.
4.4.12.1.2. Continuing the example, if hours are saved from multiple positions, but a
position is not deleted (or re-purposed), then there are no savings and the cost should
be recorded as five people for Alternative 2. In this case, the reduced hours are
accounted for in the benefit analysis. This benefit is commonly referred to as cost
avoidance.
4.4.12.2. Generally speaking, an analyst should only show the cost of the alternatives and
not make a statement about savings.
4.4.12.2.1. Savings, when calculated, can only be calculated from a currently approved
(funded) program as the baseline. Although approved funding is limited to the Future
Years Defense Program, reductions reasonably likely to occur beyond the Future Years
Defense Program period are also savings because they are reducing cost for a program
or function that is assumed to be approved.
4.4.12.2.2. The status quo should represent the currently approved (funded) program
(plus extension beyond the FYDP). Sometimes, in addition to the status quo, an
analysis will contain a Status Quo Prime. One reason to include a Status Quo Prime is
to reflect a shortfall in funding. If this is done, the analyst should not leave the
impression that the resulting difference between Status Quo Prime and the alternatives
reflects savings. If an alternative were selected and executed, the amount between
Status Quo Prime and Status Quo would be cost avoidance and the difference between
Status Quo and the alternative would be savings.
4.4.12.2.3. If savings are calculated, they should be categorized into three time periods:
budget year, FYDP, and beyond FYDP. This structuring of savings allows for
recognition of the level of certainty of the funding.
4.4.13. Revenue
4.4.13.1. In the context of a Comparative Analysis, revenues are funds remitted to the US
government as a result of a service performed or good provided in one of the alternatives.
4.4.13.2. Revenue should be included as a “negative cost” in the cost analysis.
AFMAN65-506 6 SEPTEMBER 2019 27
4.5. Other Considerations in the Cost Analysis
4.5.1. Base year: Usually defined as the FY in which a program was/will be initially funded.
This will normally be the Start Year of the analysis. When reporting costs in constant dollars,
they should be reported in the dollars of the base year of the analysis. Do not confuse this Base
Year of Analysis with the base year of an Acquisition program, which is often set for the
Selective Acquisition Report at Milestone B.
4.5.2. Economic life: The economic life of a project or asset is the time during which benefits
from the project or asset may reasonably be expected to accrue to the Air Force. The economic
life of a project or asset is set by the shortest of its physical life, technological life, or mission
life. Economic lives of assets can often be found in functional area directives for planning,
programming, and budgeting for resources. Appendix 3 of Office of Management and Budget
(OMB) Circular A-76 also has a Useful Life and Disposal Value table.
4.5.2.1. Physical life: The number of years a facility or piece of equipment can physically
be used before it wears out.
4.5.2.2. Mission life: The estimated number of years that the need for the asset is
anticipated, before the mission either changes or is no longer required.
4.5.2.3. Technological life: The period before improved technology makes an asset
obsolete.
4.5.3. Period of analysis: Economic life plus project lead-time determine the period of analysis
for a comparative analysis. If the alternatives do not have equal lives, there are multiple
methods of selecting a period of analysis:
4.5.3.1. Terminal Value Method
4.5.3.1.1. The Terminal Value Method uses the terminal value or “salvage” value to
account for unequal economic lives of assets.
4.5.3.1.2. This method sets the period of the analysis to the duration of the alternative
with the shortest economic life.
4.5.3.1.2.1. The terminal and residual values of assets are included as inflows, or
negative cost amounts, in the final period cash flows for each alternative. This
adjusts the present value of the net cash flow for the disparity between the lives of
the alternatives. See section 4.5.8 for more information about the remaining value
of an asset at the end of its useful life.
4.5.3.1.2.2. To calculate the present value of each alternative under this approach,
the analyst needs to know the terminal or "salvage" values of the assets for the
alternative with the shortest life. For example, an engine replacement program may
plan to sell the status quo engines for scrap when they reach the end of their
economic lives.
4.5.3.1.2.3. The analyst also needs to know the residual values of the asset(s) for
the alternative(s) with longer economic life (lives). For example, an engine
replacement program would include the residual value of the replacement engines
when comparing those engines against the status quo.
28 AFMAN65-506 6 SEPTEMBER 2019
4.5.3.2. Common Denominator Method
4.5.3.2.1. This method assumes the assets associated with each alternative are replaced
in the last year of their lives with identical equipment, and replacement continues until
all alternatives have assets reaching the last year of their lives during the same year.
Choose that year as the last year of the analysis.
4.5.3.2.2. It is important to keep in mind the major assumption being made: that
“chaining” the assets in this manner represents a realistic investment strategy. This
approach is not recommended for use with an asset having a short technological life
(e.g., computer hardware and software).
4.5.3.3. Uniform Annual Cost (also called Equivalent Annual Cost)
4.5.3.3.1. The Uniform Annual Cost method reflects a present value estimate of the
average annual cost for each alternative. In this method, the present value of the costs
are divided by the years in the economic life.
4.5.3.3.2. The period of analysis under Uniform Annual Cost is equal to the economic
life of the alternative with the longest economic life.
4.5.3.3.3. This method can be used in place of the Terminal Value Method.
4.5.4. Incremental Cost
4.5.4.1. The intent of this section is to better describe incremental costs, or the difference
in costs that will be expended between the base case (usually the Status Quo alternative)
and the other alternatives.
4.5.4.2. For each alternative, the estimate will include the incremental change in cost that
will have to be expended in order to execute the alternative being evaluated. The cost that
is included should be the incremental cost to the decision. In other words, only include
costs that will change as a result of the decision. (T-2).
4.5.4.3. Sunk costs and wash costs fit in the category of costs that are not incremental to
the decision.
4.5.4.4. Another category of costs that are commonly not incremental to the decision are
overhead costs. Depending on the magnitude change resulting from the decision, there
may be no change in overhead costs at all. However, if the change is large enough, then
there may be changes in infrastructure, base operating support, and other overhead that
need to be included in the analysis.
AFMAN65-506 6 SEPTEMBER 2019 29
Figure 4.2. Incremental Cost Example.
4.5.5. Confidence Levels
4.5.5.1. If cost risk was assessed in the estimate for one alternative, cost risk should also
be included for other alternatives, where appropriate, and all alternatives should be
evaluated at similar confidence levels.
30 AFMAN65-506 6 SEPTEMBER 2019
4.5.5.2. Common methods for assessing cost risk include:
4.5.5.2.1. Enhanced Scenario-based method: the analyst quantifies what can go right
and what can go wrong with a program/project from a high-level perspective (as
opposed to the more detailed level perspective common to simulation). The result
provides an estimated cumulative probability for the true program cost. More
information can be obtained from the Joint Agency Cost, Schedule, Risk and
Uncertainty Handbook.
4.5.5.2.2. Simulation is also used to evaluate risk in cost estimates. There are a variety
of software packages that can be used to assist with using simulation to evaluate cost
risk. Two common methods of applying simulation to cost risk are the Cost Informed
by Schedule Method and the Fully Integrated Cost/Schedule Method. More
information can be found on these methods in the Joint Agency Cost, Schedule, Risk
and Uncertainty Handbook.
4.5.6. Monetary Benefits
4.5.6.1. Monetary Benefits include revenues and savings as defined in the glossary to this
manual. Monetary benefits are included in the cost analysis. This does not include benefits
that could be dollarized, but would not result in revenue or savings.
4.5.6.2. Benefits that could be dollarized, but would not result in revenue or savings should
be recorded in the benefit analysis as per paragraph 5.3.2.2
4.5.7. Discounting and Present Value.
4.5.7.1. Discounting is a method of calculating the value today (present value) of a future
cost or stream of future costs.
4.5.7.2. The Air Force evaluates decisions using present value dollars (discounted dollars).
4.5.7.3. Discount Rates Discount rates are the rates used to calculate present value in a
comparative analysis. In order to simplify the present value calculation, the rates are
sometimes converted to discount factors. The simplification is that the present value can
then be easily calculated by multiplying the discount factors with the stream of dollar
values.
4.5.7.4. Where to find discount rates. Comparative Analyses are performed using discount
rates that represent the government's cost of borrowing, as provided annually in the
President's Budget and Appendix C to OMB Circular A-94.
4.5.7.4.1. Rates used for analysis are interest rates on Treasury notes and bonds with
maturities of 3, 5, 7, 10, 20 and 30 years. The rate to be used should correspond to the
period of analysis for the project. Projects with terms different from those listed should
use a linear interpolation. For example, a four-year project can be evaluated with a rate
equal to the average of the three-year and five-year rates. Projects with durations longer
than 30 years may use the 30-year interest rate.
4.5.7.4.2. Interest rates on Treasury securities are cited on both a real and nominal
basis. For an estimate in constant year dollars, use a real rate. For an estimate in then-
year dollars, use the nominal rate.
AFMAN65-506 6 SEPTEMBER 2019 31
4.5.7.5. Discount Factors. Discount factors for use in comparative analyses are derived
from the discount rate used, using the formulas found in Attachment 7. There are two
kinds of discount factors that are common in Air Force comparative analyses.
4.5.7.5.1. Midyear Factors: When costs and benefits occur in a steady stream,
applying midyear discount factors is more appropriate. Midyear factors approximate
actual disbursement patterns--i.e., funds are typically disbursed throughout a given FY
rather than at its beginning or end. When the precise timing of outlays is critical to
program evaluation, monthly (or quarterly) rather than annual flows of funds may be
considered for early program years. Midyear factors should be used in Air Force
comparative analyses unless there is good reason to use other factors, in which case the
reason(s) should be explained in the analysis.
4.5.7.5.2. End-of-Year Factors: These factors implicitly assume that costs and benefits
occur as lump sums at year-end.
4.5.8. Remaining value at the end of an asset’s useful life (i.e., physical life, mission life, or
technological life).
4.5.8.1. The remaining values of assets are included as inflows, or negative dollar
amounts, in the final period of the cost analysis for each alternative. This step adjusts the
present value of the net cash flow for the differences between the lives of the alternatives.
A straight-line depreciation method is acceptable for estimating terminal, residual or
salvage value. This is done only to estimate the remaining value of existing assets, and for
no other purpose.
4.5.8.2. There are three terms used to describe the value of an existing asset that remains
at the end of its useful life: salvage value, residual value and terminal value.
4.5.8.2.1. Salvage value is the value of an asset at the end of its physical life (scrap
value). Salvage value is often offset by the cost to dispose of the asset.
4.5.8.2.2. Residual value is the value of an asset at any point in time before the end of
its economic life.
4.5.8.2.3. Terminal value is the value of an asset remaining at the end of its economic
life. If its economic life is deemed to be the same as its physical life, then terminal
value will equal salvage value. If, however, an asset’s physical life is longer than its
mission or technological life, there may be some value left in the asset beyond salvage
value.

BENEFIT ANALYSIS
5.1. Overview Benefit Analysis
5.1.1. An essential and critical element of an economic analysis is the consideration of
benefits. Without a consideration of benefits, the analysis is a cost comparison, not a
comparative analysis.
5.1.2. For the purpose of a comparative analysis, the benefit analysis section is generally
limited to non-monetary impacts. That is, the benefit analysis includes those aspects of the
alternatives that are not represented as a cash flow within the analysis.
5.1.3. There can be both qualitative and quantitative benefits and both types are important to
consider. Quantifying an otherwise qualitative benefit is useful for analysis, but does not
eliminate subjectivity. Weighting benefits is an important way to assess their relative value to
the decision.
5.1.4. All benefit elements that are analyzed should be fully explained so that someone
unfamiliar with them can fully understand the benefit and its measurement.
5.2. Role of Benefits
5.2.1. The purpose of benefit analysis is to identify, measure, and evaluate the benefits
provided by each of the proposed alternatives.
5.2.2. Since benefits reflect the performance of the organizational mission or service desired,
they are the primary reason for a project. While costs can be thought of as “inputs” to a project
or program, benefits can be thought of as the “output” or what the government receives for the
resources input. Considering benefits is essential to a comparative analysis. Benefits or results
are the reasons for the investment, but there can also be benefits that are ancillary to the
objective. These ancillary benefits can be recognized in the analysis, but should be secondary
to those benefits that are directly related to the project objective.
5.2.3. The selection of any particular alternative should be based on a full economic
evaluation, in which costs and benefits are appropriately weighed and compared. An
alternative with the lowest cost may not be the preferred alternative after costs and benefits are
considered together.
5.3. Types of Benefits
5.3.1. The benefits section focuses on non-monetary impacts. If implementing an alternative
would result in a reduced operating cost, then that reduced cost should be reflected in the cost
analysis, not the benefit analysis. Similarly, if one of the alternatives results in revenue to the
Air Force, then that should be reflected in the cost analysis, not the benefit analysis.
5.3.2. There are two types of benefits quantitative and qualitative.
5.3.2.1. Quantitative benefits
AFMAN65-506 6 SEPTEMBER 2019 33
5.3.2.1.1. Quantitative benefits are any benefits that can be measured quantifiably such
as a reduction in military man-hours. Characteristics like product or service
performance (e.g., miles/hour, orders/hour) or work environment (e.g., average noise
level, mishaps/week) often can be quantified. In such cases, these benefits should be
quantified to the greatest extent possible, and direct comparisons for each of these
measures across alternatives should be made.
5.3.2.1.2. Express these quantitative benefits in the units they naturally occur (e.g.,
military overtime hours, miles/hour) instead of converting the benefit into dollars.
Converting the benefit into dollars may mislead the decision maker into thinking that
such quantifications represent actual dollar cash flows.
5.3.2.1.3. Quantitative benefits in their unit, or raw, form should not be aggregated
across benefits. Since they are in different units, they should be presented as individual
benefits instead of an aggregated measure. If the quantitative benefits are converted to
percentages (e.g., 500 parking spaces out of 1,000 desired equals 50% of the desired
spaces) and weighted (see section 5.4.6), then they may be aggregated into a single
benefit score.
5.3.2.1.4. Cost Avoidance Benefits.
5.3.2.1.4.1. Cost avoidances are areas where someone may think the budget will
be affected when, in fact, it will not be. As a result, cost avoidance is accounted
for as a benefit.
5.3.2.1.4.2. There are two types of cost avoidance.
5.3.2.1.4.2.1. The first type of cost avoidance is productivity gains that do not
result in budget savings, such as man-hour savings that do not result in a deleted
position. Productivity efficiencies should be accounted for in their naturally
occurring metric (e.g., hours) instead of being converted to dollars.
5.3.2.1.4.2.2. The second type is a reduction in some future resource
requirement which: (a) has not been included in an approved (funded) Air
Force program or function within the Future Years Defense Program, and (b)
would not be reasonably assumed to be included in an Air Force approved
program beyond the Future Years Defense Program. This type of cost
avoidance benefit is the only benefit that should be measured in terms of dollars.
While the Air Force would not experience a reduction in funding from this
benefit, it represents the reduction in a potential liability. For example, if the
status quo anticipates the purchase of certain hardware which has not been
included in an approved and funded Air Force program, but implementation of
the preferred alternative does not require its purchase, there is a cost avoidance.
5.3.2.1.4.3. Cost avoidances can accrue at any time during the life cycle.
5.3.2.2. Qualitative benefits
5.3.2.2.1. Qualitative benefits are not naturally measured in quantities (e.g., mission
effectiveness, security, organizational morale). These benefits are usually subjective
in nature and generally do not lend themselves to quantitative analysis.
34 AFMAN65-506 6 SEPTEMBER 2019
5.3.2.2.2. There are techniques available which attempt to determine the comparative
desirability of each alternative with respect to each benefit and also attempt to measure
the magnitude of the differences in desirability between alternatives. While these
techniques do not measure qualitative benefits in an objectively quantitative way, this
approach allows us to establish a numeric basis of comparison. See Section 5.4.7 and
Figures 5.2, 5.3 and 5.4.
5.4. Basic Steps for Benefit Analysis
5.4.1. The steps for doing a benefit analysis are iterative in that the information gained from a
subsequent step may require the analyst to go back to a prior step.
5.4.2. Review Foundational Elements
5.4.2.1. The benefit analysis should be based on the objective statement and scope.
Reviewing the foundational elements will help keep the analysis focused on the decision
to be made.
5.4.2.2. The benefits developed should be benefits to the government within the scope of
the analysis, not simply those incurred by the function under study.
5.4.3. Identify Benefit Elements
5.4.3.1. The benefit element structure is the framework for building the benefit analysis.
5.4.3.2. The benefit element structure varies depending on the analysis. Structures can
vary from a list of high level benefits to a hierarchical breakdown of the benefits for the
project being analyzed. The benefits included in the structure must be mutually exclusive.
5.4.3.3. The analyst should receive input on identifying benefits from multiple
stakeholders representing multiple viewpoints. As an example, consider a proposal to
provide temporary lodging. From the viewpoint of the facility manager, benefits include:
capacity, housekeeping productivity and security. For the customer, benefits include:
location, comfort, security, and amenities. More broadly, the government may also have a
concern about the environmental impact. This highlights the need to include multiple
stakeholders when measuring benefits.
5.4.3.4. In developing the list of benefits, care must be taken to avoid double-counting
impacts which are accounted for in the cost analysis, and, if included, the risk analyses.
For example, reduced manpower positions are captured in the cost analysis; the hours
associated with those positions should not be captured as a benefit. Risk sometimes can
be assessed in the benefits section; however, if a separate risk analysis is included, ensure
that the benefit analysis does not assess the same risks.
5.4.3.4.1. While an analyst should be careful not to double count, there may be some
elements in the analysis that impact both costs and benefits.
5.4.3.4.2. As an example, while the cost associated with reduced fuel consumption is
accounted for in the cost analysis, there are aspects of it that could be considered a
benefit such as reduced pollution.
5.4.4. Select Benefit Measurement Technique
AFMAN65-506 6 SEPTEMBER 2019 35
5.4.4.1. The analysis technique will depend on the available data, time available and the
ability of the technique to provide the decision-maker with an accurate view of the benefits
received by alternative.
5.4.4.2. The following are different types of measurement.
5.4.4.2.1. Quantitative Measures
5.4.4.2.1.1. Quantitative benefits are measured in a variety of units. Measures
could include physical counts of tangible items, but it can also include other
measures, such as the square feet of a building, the age of a building, the speed of
an aircraft, or the weight of an aircraft. Many times the interpretation of
quantitative data is intuitive and can be easily used in calculations, but that is not
always the case.
5.4.4.2.1.2. Some benefit data requires additional consideration in how it is
interpreted and used in calculations. As an example, with reduced fuel
consumption there are aspects of it that could be considered a benefit both in terms
of reduced pollution and in terms of the logistical footprint of a deployed unit.
Additionally, when measuring fuel consumption of an aircraft, the analyst should
understand that the consumption is not linear over a flight. Instead, more fuel is
consumed in takeoff (per unit of time) than while cruising. As a result, saving one
hour in a ten hour flight will not result in consuming 10% less fuel.
5.4.4.2.1.3. For some data the distance between values is meaningful, but the ratio
between two values is not. As an example, engine temperature (as measured in
Fahrenheit) is an interval measure. The interval between 100 degrees and 101
degrees is meaningful, but 200 degrees is not twice as hot as 100 degrees because
0 degrees Fahrenheit does not represent the absence of heat.
5.4.4.2.1.4. Another simple but important concern is understanding the unit of
measure used (e.g., Fahrenheit versus Kelvin, miles versus kilometers, tons versus
long tons).
5.4.4.2.1.5. How data has been calculated/normalized prior to receiving it is
important to understand as well. If an analyst was provided the average deployment
days for different types of units, it would be good to know how the average
deployed days was calculated. Deployed days across all people divided by total
days available for all people will yield a different answer than the average length
of deployment (in days) for those who deployed.
5.4.4.2.2. Qualitative Measures
5.4.4.2.2.1. Ordinal measures
5.4.4.2.2.1.1. Ordinal measures of benefits can be arranged in an order (e.g.,
ranking of outstanding/good/satisfactory/inadequate, high to low, 1 to 5 star
hotels).
5.4.4.2.2.1.2. These subjective values may not be on a linear scale and may be
numeric or descriptive.
36 AFMAN65-506 6 SEPTEMBER 2019
5.4.4.2.2.1.3. Even though the measurement may be numeric, it is not
appropriate to do calculations with the raw measurement.
5.4.4.2.2.2. Narrative descriptions
5.4.4.2.2.2.1. With narrative benefits, the merits of each alternative are
qualitatively described for each benefit element.
5.4.4.2.2.2.2. Even with narrative benefits, the analysis can provide a weight
for each benefit to show the level of importance attributed to each benefit
element in the assessment.
5.4.4.3. The level of measurement at which benefits data will be collected is important
because it defines the subsequent analysis that can be done with the data. For example,
with narrative descriptions applying a weight to each benefit would be the only possible
computation that could be applied.
5.4.4.4. It is important to note that assigning numeric values to an otherwise qualitative
benefit (e.g., morale) induces a measure of an individual or group’s opinion, but it does not
eliminate subjectivity. (See paragraph 5.4.7.2.5 for more information on assigning
numeric values to benefits that are otherwise qualitative). Further, when assigning numeric
values to these benefits, it is important to understand and document the substantive impact
behind the measurement (e.g., the new building has greater physical security because it is
50 meters behind a fence line and thus less vulnerable to terrorist attack).
5.4.5. Collect Benefit Measurement Data
5.4.5.1. Data collection applies to benefits as well as costs. For benefits, data can take a
wide variety of forms from quantitative performance measures (e.g., miles per hour) to
more subjective measures (e.g., morale). Data collection should occur as early as possible
because it may be difficult to find good data. Similarly, data collection and the selection
of benefit analysis techniques are normally done simultaneously because the technique
depends on available data.
5.4.5.2. As data is collected, use the selected estimating techniques to begin populating the
analysis.
5.4.5.3. Because of the comparative nature of economic analysis, quantification of benefits
or outputs can be very helpful. When results are quantitative, they can be measured which
may facilitate comparison of the alternatives.
AFMAN65-506 6 SEPTEMBER 2019 37
Figure 5.1. Quantifying Benefits.
5.4.6. Prioritize (Weight) Benefits
5.4.6.1. Understanding the priority and relative value of the benefits is a critical step. The
analyst must rely on feedback from the different stakeholder viewpoints discussed under
measuring benefits. While the prioritization of benefits is subject to the approval of the
decision authority, often the analyst is the person to propose a prioritization. The
development of priorities should have traceability back to the stakeholder viewpoints.
5.4.6.2. In this step, the analyst is trying to determine the intrinsic value of one benefit
relative to other benefits for the decision.
5.4.6.2.1. Realizing that some benefit elements will have greater influence than others
on a particular decision, the analyst or decision-maker should consider developing a
method of assessing the degree of influence through prioritization.
5.4.6.2.1.1. When benefits are only addressed narratively, they are not required to
be prioritized; by default this leaves prioritization up to the decision-maker by the
analysis being silent.
5.4.6.2.1.2. If a prioritization method is used for some benefits, it must be applied
to all benefits. (T-3). When an analysis uses both scored and narrative benefits,
prioritization is required for all benefits.
5.4.6.2.2. One common method of prioritizing is to give a numerical weight to the
benefits an ordinal ranking may also be used. If the benefits are organized in a
hierarchy, then each level of the hierarchy is weighted. Figure 5.1 provides an example
of benefit weighting. In this approach, the percentages allocated to the elements at the
second level in the hierarchy must sum to 100% and the percentages allocated to the
children benefits within each of the second level elements must sum to 100%.
38 AFMAN65-506 6 SEPTEMBER 2019
Figure 5.2. Benefit Weighting Example.
5.4.7. Evaluate Benefits by Alternative
5.4.7.1. Identifying Infeasible Alternatives
5.4.7.1.1. Commonly alternatives are vetted early in the comparative analysis process
to determine their feasibility. However, through additional research, an analyst may
discover that an otherwise feasible alternative may be identified as infeasible as a result
of the benefits analysis.
5.4.7.1.2. Satisficing
5.4.7.1.2.1. Satisficing is one method for identifying infeasible alternatives before
completing the entire benefits analysis.
5.4.7.1.2.2. Satisficing uses absolute minimum requirements or maximum limits
to eliminate alternatives. Once the benefits for the analysis have been identified,
determine if there are any alternatives that do not satisfy minimum performance
standards for each benefit. If an alternative fails to meet the minimum requirement
for even one benefit, it is an unacceptable or infeasible alternative. The infeasible
alternative can be eliminated from further consideration in the economic analysis.
The reason for eliminating the alternative should be stated in the narrative of the
analysis. Continue the benefits analysis considering only the remaining feasible
alternatives.
5.4.7.2. Benefit Evaluation and Comparison
AFMAN65-506 6 SEPTEMBER 2019 39
5.4.7.2.1. There are several ways to compare the benefits of the alternatives. The
complexity of the comparison can vary significantly. A few ways to compare benefits
are described below.
5.4.7.2.2. Dominance
5.4.7.2.2.1. If one alternative is rated the best under every attribute considered in
the analysis, that alternative dominates the others.
5.4.7.2.2.2. If the alternative that was dominant in the benefits analysis is also the
least costly, the interpretation of the results of the analysis may be straight forward
(unless a sensitivity analysis raises concerns).
5.4.7.2.3. Comparison of Raw Quantitative Measures
5.4.7.2.3.1. Raw quantitative measures may be used to compare alternatives (e.g.,
aircraft cargo hold size, aircraft range). The drawback to using raw quantitative
measures is that they do not provide the decision-maker with information on how
other stakeholders (e.g., users of the system) value the measure.
5.4.7.2.3.2. Using this technique depends on the decision-maker being able to
understand the value the measure provides to the Air Force. When the quantitative
measures are further evaluated (e.g., in a weighted point rating), the raw measures
should still be noted in the analysis so the decision-maker has an understanding of
the raw benefits the Air Force will receive.
5.4.7.2.4. Relative Ranking
5.4.7.2.4.1. Relative ranking requires the collection of ordinal data.
5.4.7.2.4.2. This system is based on two assumptions: (1) all alternatives are at
least adequate in all benefit areas, and (2) no two alternatives provide the exact
same level of value for a particular benefit element.
5.4.7.2.4.3. Each alternative is evaluated in direct competition with all other
alternatives, and is placed in a relative ranking position with all other alternatives
for a particular benefit element. No two alternatives can be ranked in the same
position; each must be ranked above or below all others.
5.4.7.2.4.4. In Relative Ranking without weighting, it is assumed that all benefit
elements have equal value. An example is provided in Figure 5.2 below. In the
example, a higher rank (higher number) represents a more desired alternative.
Figure 5.3. Relative Ranking without Weights.
40 AFMAN65-506 6 SEPTEMBER 2019
5.4.7.2.5. Relative Ranking with Weights
5.4.7.2.5.1. Assigning weights to each benefit element signifies that each of the
benefit elements are valued differently. For example, if security and functionality
are benefits elements in the analysis, an analyst would give security a greater weight
in the study if it was more important to the decision than functionality.
5.4.7.2.5.2. An example summary table from using the Relative Ranking with
Weights technique is provided in Figure 5.3. The weights associated with the
benefit elements could be key information for the decision-maker. As shown
below, while Alternative B is ranked very highly in both comfort and environment,
the weights for these benefit elements is low. As a result, the decision-maker may
discount those scores for Alternative B. Conversely, Alternative D may be
considered more important because it was ranked highly in benefit elements that
carried a higher weight.
Figure 5.4. Relative Ranking with Weights.
5.4.7.2.6. Weighted Point Rating
5.4.7.2.6.1. The weighted point rating technique requires the analyst, stakeholders
and/or decision-maker to examine their individual valuation, preferences, etc. with
respect to the alternatives and assign values to the benefits for each alternative.
5.4.7.2.6.2. There is a significant amount of subjectivity involved in this approach,
while, at the same time, it provides a single numerical score for the total value of
all benefits which appears to be objective. When using this method, it is critical to
ensure the analysis presents the meaning of the benefits behind the scores. The
mathematical score presented without any additional information can provide the
appearance of certainty without giving the decision maker substantive information
about the benefits.
5.4.7.2.6.3. The weighted point rating system is a comprehensive evaluation
method that involves:
5.4.7.2.6.3.1. Value The establishment of a numerical value for each benefit
that would result from executing an alternative. In the figures below (Figures
5.3 and 5.4), the values are referred to as a score and expressed as a percent.
Expressing values as a percent is a typical method of measuring the benefit
elements using a common measure so they can be aggregated later.
5.4.7.2.6.3.1.1. This numerical value could be assigned directly by those
determining the value of each alternative by benefit element.
AFMAN65-506 6 SEPTEMBER 2019 41
5.4.7.2.6.3.1.2. A more rigorous method would take a two-step process. The
first step is to measure the benefit. This works well for benefits that already
have quantitative measures (e.g., number of training deficiencies). The
second step is to use a value function to determine the stakeholder’s relative
value for the different levels of performance for each measure over the range
needed to evaluate the alternatives. For example, how much more valuable
is it to the organization if personnel exit training with only 2 training
deficiencies versus 20.
5.4.7.2.6.3.1.3. Whether assigning values directly, or using the two step
process, the analyst should provide an intuitive explanation of the resulting
value. Just seeing a number without context will not be meaningful to a
decision-maker.
5.4.7.2.6.3.2. Weight The assignment of weights to each benefit element
accounts for the fact that each of the benefit elements are valued differently.
For example, if security and morale are benefits elements in the analysis, an
analyst would give security a greater weight in the study if it was more
important to the decision than morale.
5.4.7.2.6.3.3. Composite The calculation of a composite score (using value
and benefit element weight) for ranking of the alternatives.
5.4.7.2.6.4. The weight of each benefit should reflect how important each benefit
is relative to the others, while the value should measure how well the alternative
provides that benefit. The weight multiplied by the score equals the composite
score. These are then summed to show the various alternatives’ overall weighted
benefit score.
5.4.7.2.6.5. Many times the benefits are weighted and scored at a summary level.
When benefits are weighted and scored as a hierarchy, the calculations are a bit
more complex.
5.4.7.2.6.6. Figure 5.4 shows benefits evaluated at a summary level. This is a
common method of benefit evaluation.
Figure 5.5. Weighted Benefits Score Evaluated at a Summary Level.
42 AFMAN65-506 6 SEPTEMBER 2019
5.4.7.2.6.7. Figure 5.5 shows benefits evaluated as a hierarchy. In this case,
benefits are evaluated at the lowest level of the hierarchy and then aggregated. The
aggregated scores for each benefit element are then multiplied by the weight for the
element to obtain an element weighted score. The sum of the element weighted
scores by alternative equals the total benefit score for each alternative.
Figure 5.6. Benefits Evaluated as a Hierarchy.
5.4.7.2.7. Narrative Benefit Comparison
5.4.7.2.7.1. Alternatives can be compared using narrative-only descriptions of how
the alternatives perform under each of the benefit elements. Narrative-only
descriptions should provide the decision-maker with a rich understanding of what
each alternative will provide and the context behind why one alternative is superior
to (or equal to) another for each benefit element.
5.4.7.2.7.2. The Narrative benefit elements can also be given weights based on the
significance of the benefit element. The purpose of weighting this type of benefit
would be to give the decision-maker additional information on which benefits merit
more attention.
5.4.8. Time Phasing and Discounting
5.4.8.1. When scoring benefits, the person evaluating the benefit should take into account
the value of the benefit over time.
5.4.8.2. In doing so, the analyst will have accounted for the benefit over the entire period
of analysis.
AFMAN65-506 6 SEPTEMBER 2019 43
5.5. Other Benefit Considerations
5.5.1. Individual benefits to be analyzed are best selected, weighted and scored by
knowledgeable personnel from relevant functional areas, like civil engineering, safety, security
forces, financial management or services, etc.
5.5.2. In the analysis, each benefit should have a brief separate paragraph describing what the
benefit is, what is being measured, and the rationale used in determining the score for each.
5.5.3. The sources and derivation of quantitative benefits must be documented in the same
level of detail as costs, and should include all interim calculations as appropriate. (T-2).
5.5.4. Realized Benefits This is the benefit equivalent of sunk costs. The analysis should
only include benefits over the period of analysis. Benefits realized prior to the period of
analysis are excluded from consideration. In situations where questions on realized benefits
might arise, they should be documented in the analysis.
5.5.5. Wash (Common) Benefits Wash benefits are also referred to as common benefits.
This is the benefit equivalent of wash costs. These are benefits that will be realized regardless
of the alternative implemented. Wash benefits are optional to include in an analysis.

Chapter 6
UNCERTAINTY (RISK AND SENSITIVITY) ANALYSIS
6.1. Uncertainty Analysis Overview
6.1.1. Estimates of costs and benefits contain uncertainties. Since estimating errors can be
introduced into the analysis because of the uncertainty, the potential impact of these errors
must be analyzed.
6.1.2. Uncertainty, and the related errors introduced, in comparative analyses is primarily
addressed through risk and sensitivity analyses. It is important to have an understanding of
how the Department of Defense defines risk and sensitivity analysis.
6.1.2.1. Risk is the probability an unfavorable outcome or event will occur. Risk analysis
evaluates the probability and severity of the potential unfavorable outcomes.
6.1.2.2. Sensitivity is the magnitude of impact that particular inputs have on an analysis
and its results. Sensitivity analysis is an evaluation of the effect that uncertain elements of
an analysis have on the outcome.
6.1.2.3. Every comparative analysis must have a separate sensitivity analysis (see section
6.2 of this manual). (T-1). An analyst can also assess the risk associated with each
alternative (see section 6.3.2 of this manual).
6.1.3. Assumptions of any type and level, by virtue of not being facts, introduce uncertainty
into the analysis. Sensitivity analysis examines the impact to the analysis of changing the level
or value of the assumption. If the baseline value of the assumption assumed for the analysis is
not just uncertain (i.e., its value is not known with certainty) but, if it is also too
optimistic/pessimistic, it introduces risk around the alternative(s), (i.e., increases the
probability that the alternative will not execute in the same manner as the analysis presents).
In the case of optimistic/pessimistic assumptions, sensitivity analysis is required. If a risk
analysis is included in the analysis, optimistic/pessimistic assumptions should be included.
6.2. Sensitivity Analysis
6.2.1. Sensitivity analysis identifies key assumptions and variables within an economic
analysis and determines how changes in value of those assumptions and variables affect the
results of the analysis. Its value lies in the additional information and understanding it brings
to bear on the decision. For decision makers facing an investment decision, sensitivity analysis
is a tool for determining how changes in assumptions and the values of variables (e.g., due to
estimating errors that stem from uncertainty) affect the analysis results. A sensitivity analysis
can be particularly important when the results of the cost and benefit analysis do not clearly
favor one of the alternatives.
6.2.1.1. A decision is insensitive to uncertainties regarding a variable if that variable’s
value can vary over a wide range without affecting the results of the alternatives relative to
each other. A sensitivity analysis demonstrates the stability (or instability) of the results.
AFMAN65-506 6 SEPTEMBER 2019 45
6.2.1.2. Two major limitations of sensitivity analysis are that (1) it only analyzes the
assumptions and variables that have been considered and (2) each assumption or variable
is analyzed in isolation. These limitations emphasize that critical thinking and dialogue
with experts is crucial to preparing a quality analysis.
6.2.2. Sensitivity analyses are commonly performed:
6.2.2.1. On uncertain assumptions that can impact the estimates of costs or benefits.
6.2.2.2. On major cost drivers, those parameters of the analysis that have the largest impact
on the discounted life cycle cost. In some cases, there may be a cost element that is a high
percentage of program cost, but is actually a “passenger,” meaning that it is driven by a
cost driver but has no parameter itself that can be adjusted to actually impact the cost of
the program. In this case, the sensitivity analysis would not be performed on the passenger.
Instead, the analyst would perform analysis on the parameter that is driving cost.
6.2.2.3. On major benefit drivers, those parameters that have a large impact in a weighted
point benefit assessment.
6.2.3. To perform a sensitivity analysis, vary an uncertain assumption or variable value within
what is considered to be a reasonable and relevant range (e.g., plus or minus 10% of initial
investment costs, plus or minus $3.50 per operating hour, or whatever is appropriate).
Recalculate the costs and benefits of all affected alternatives and compare them again. Several
iterations can be accomplished, varying the assumption or variable value at whatever interval
(e.g., every 2%) the analyst thinks is appropriate. Continue until the assumption or variable
value being varied becomes too unreasonable. Make sure to document the reasoning and show
calculations and intermediate steps. This level of documentation may be either in the
comparative analysis report, or in an appendix that would be made available if needed. If a
sensitivity analysis yields a change in the cost or benefit ranking of alternatives, report the
value at which the change occurs. If no change in alternative ranking occurs, report that, as
well, so the decision maker will understand the stability of the alternative rankings. If the
sensitivity analysis of a discount rate results in a change in the cost ranking of alternatives,
report the rate at which the change occurs.
6.2.4. Scenario Analysis
6.2.4.1. A scenario analysis is similar to a sensitivity analysis. In a sensitivity analysis,
one variable is allowed to change so that a decision maker can understand the effect that
variable has on the results of the analysis.
6.2.4.2. In a scenario analysis, the analyst allows multiple variables to change
simultaneously to gain insight into their combined impact. This can be a particularly
effective tool if there are multiple assumptions or cost drivers that the analyst considers
particularly questionable in the baseline analysis or if changing one variable almost always
impacts a related variable in the analysis.
6.3. Risk Analysis
6.3.1. A risk analysis can assess uncertainty in a manner different from sensitivity analysis.
6.3.2. When to include a risk analysis:

6.3.2.1. Through the analysis process, if the analyst develops an understanding through
conversations with subject matter experts and stakeholders that the level of risk associated
with any alternative has a reasonable likelihood of being a key consideration for the
decision-maker, then a risk analysis should be performed.
6.3.2.2. A risk analysis should be included when required by the type of analysis or the
decision-maker.
6.3.3. A risk matrix is a common mechanism for evaluating risk. (See paragraph 6.3.10 Risk
can also be expressed narratively in the analysis).
6.3.4. Risk can occur in many forms. Some examples include: optimistic assumptions,
insufficient funding, schedule delays, immature technology, legislative requirements, biased
data, or contractor inability to execute. Risk can be found in a variety of areas. There is some
risk that the benefits expected from an alternative may not be achieved. There is also risk of
project execution that may not be easily expressed within the benefit element framework.
6.3.5. A risk analysis can include an evaluation of the level of confidence associated with
assumptions in the benefit analysis. In this case, the risk analysis is evaluating the probability
of not achieving the benefit attributed to a particular alternative. A risk analysis could also
focus on those benefit elements that have a particularly large impact on the results.
6.3.6. Cost risk is often assessed within the cost estimate. If the cost estimate includes an
assessment of cost risk, do not include a separate assessment of cost risk in this section of the
analysis (See paragraph 4.5.5).
6.3.7. Political risk (the risk associated with Congressional action or inaction) should only be
included when directed by an Air Force senior leader. Any assessment of political risk should
be provided by qualified subject matter experts (e.g., legislative liaison).
6.3.8. If a risk element is assessed low for an alternative because a mitigation is anticipated,
then the cost of mitigation should be addressed either in the cost analysis, or as a sensitivity
analysis. For example, the Air Force may have a risk of not obtaining data rights to a weapon
system, but as a mitigation, the program office believes the system could be reverse engineered
to the extent that maintenance could be performed organically. In this case, if the risk is being
evaluated as low due to the mitigation, then the cost of the mitigation should be included in the
cost estimate, or at least addressed as a sensitivity analysis.
6.3.9. If one of the alternatives is evaluated as having zero risk for a particular risk element,
that measurement of zero risk should be included in subsequent aggregation and assessment of
risk.
6.3.10. Risk Matrix
6.3.10.1. A risk matrix is a common approach for assessing both the probability and
severity of a risk element or undesirable events. Risk matrices can help prioritize
uncertainties that could negatively impact program cost, schedule and benefits. Subject
matter experts familiar with the program define the risk factors, probabilities, and resulting
impact to cost, schedule, and performance.
AFMAN65-506 6 SEPTEMBER 2019 47
6.3.10.2. An example risk matrix is provided in Figure 6.1. Additional explanation is
provided in AFI 90-802, Risk Management. In this example, the matrix was built so that a
higher risk item would have a higher score. An evaluation using the risk matrix would be
conducted for each risk element and each alternative. For the example in Figure 6.1, once
risk is evaluated for a specific risk element/alternative, the relative risk associated with
each alternative for that risk element can be assessed by multiplying the values assigned to
the different levels of Likelihood and Consequence.
6.3.10.2.1. The vertical axis is an evaluation of the likelihood of the risk.
6.3.10.2.2. The horizontal axis is an evaluation of the severity of the consequence
should the undesirable event occur.
Figure 6.1. Risk Matrix Example.
6.3.10.3. When using a risk matrix, the analyst should provide definitions for the
categories of risk listed in the risk matrix so that the reader knows how the risk categories
are being applied to this analysis. Examples are below.
Figure 6.2. Definitions for Likelihood Categories.
48 AFMAN65-506 6 SEPTEMBER 2019
Figure 6.3. Definitions for Consequence Categories.
6.3.10.4. Summarizing the Risk Assessment Results
6.3.10.4.1. Figure 6.4 shows an example summary of the results. Notice that each
alternative has a risk rating for each risk element.
6.3.10.4.2. If these risk elements are also benefit elements, then the risk score reflects
not being able to meet the benefit score provided in the benefit analysis. This means
that an alternative may only have a low risk score because of the low benefit
expectation. If benefits were normalized across alternatives, the risk of achieving the
benefit would be higher. When risk scores are related to the benefit evaluation, the
implications should be explained in the documentation.
6.3.10.4.3. If these risk elements are not also benefit elements, then the risk score
reflects an absolute comparison among the alternatives.
6.3.10.4.4. In Figure 6.4, the “Prob” columns are the likelihood measure from the risk
matrix. The “Conseq” columns are the consequence measure from the risk matrix. The
score is the assessment from combining likelihood and consequence. The rating
column follows the color scheme in the risk matrix with green being low risk, yellow
being moderate risk and red being high risk.
6.3.10.4.5. The scores are aggregated to an average score by alternative.
Figure 6.4. Summary of Risk Analysis.
6.3.10.4.6. Similar to defining the risk categories, the risk elements should also be
defined. Figure 6.5 provides an example of risk element definitions.

CONCLUDING THE ANALYSIS: SUMMARY AND COMPARISON OF
ALTERNATIVES AND POST-ANALYSIS ACTIVITIES
7.1. Once the cost, benefit and uncertainty analyses are completed for each alternative: The
results must be analyzed, and the alternatives compared. (T-2). This section of the comparative
analysis includes a summary of the analysis results and a comparison of the results. The summary
of analysis presents and summarizes the key aspects of the cost, benefit, and uncertainty analyses
to then enable comparison of the alternatives. In the comparison of alternatives, the analyst
compares and interprets results. The analyst should provide more than just an explanation of the
analysis results. The analyst should provide insights into the behavior of the alternatives’ costs
and benefits from which the decision-maker could draw reasonable conclusions. The analyst is
not required to recommend an alternative, but may provide a recommendation.
7.2. Provide summary tables for: The cost analysis, benefit analysis, and uncertainty analysis
for areas where the analyses have been expressed in quantitative terms.
7.2.1. The cost summary should include a table(s) with the present value of the alternatives,
new funding required by alternative, and any other financial measures used to evaluate the
alternatives.
7.2.2. Benefits - The benefit summary should include a summary table if the benefits were
measured using: physical counts, an index/ratio, or a rating scale. If benefits were evaluated
using narrative descriptions, then those descriptions should be summarized in this section.
7.2.3. Uncertainty A summary of the results of the sensitivity analysis should be included.
If a risk assessment was performed, this also is the appropriate section to summarize those
results. If risk was measured quantitatively, a table should be included.
7.3. Provide a brief narrative explanation of: The summarized cost and benefit analyses and
uncertainty assessment, as well as any measurements and indicators.
7.4. Every comparative analysis must: Compare the alternatives and interpret the results. (T-
2).
7.4.1. Compare the relative strengths and weaknesses of each alternative with respect to cost
as well as how well each alternative meets the objective. Provide insights from the comparison.
A few examples of this type of insight are pointing out whether a particular alternative
dominates in terms of costs, benefits and risks or providing the interpretation of the results that
achieving a particular benefit will cost XX dollars over the status quo. The analyst can
highlight the tradeoffs between the alternatives and explain the conditions under which the
rankings of alternatives change.
7.4.2. There are measures to assist with comparing alternatives; some apply to costs, some to
benefits, and some to a combination of the two. The measures below provide some useful
methods by which to make comparisons between alternatives.
7.4.2.1. Comparison of Present Value (PV):
AFMAN65-506 6 SEPTEMBER 2019 51
7.4.2.1.1. Present Value reflects the value today of a future amount or stream of future
amounts, expressed as a single sum of dollars. It is calculated by multiplying the
amount for each year by the corresponding discount factor, and summing the results.
Present value is the best measure for comparing cash flows over time.
7.4.2.1.2. Net Present Value (NPV) refers to the present value of the gains (revenue)
minus the present value of the investment. Government comparative analyses often do
not have a revenue stream but may have gains through reduced costs.
7.4.2.2. Uniform Annual Cost: Uniform Annual Cost is calculated by dividing the net
present value of the costs of an alternative by the sum of the discount factors for the periods
covering the life of each alternative in which costs were incurred.
7.4.2.3. Savings/Investment Ratio: The present value of the total return generated by an
investment divided by the present value of the initial investment amount.
7.4.2.4. Return On Investment: A ratio that evaluates the return relative to the investment.
See Attachment 7 for a more detailed explanation.
7.4.2.5. Weighted Benefit Score: The result of the scoring of benefits of a given
alternative, weighted by the relative importance of each individual benefit. Multi-
Objective Decision Analysis (MODA) is an example of weighted benefit scoring.
7.4.2.6. Cost/Benefit Ratio: The ratio of the life cycle cost of an alternative to its weighted
benefit score or other quantitative measure of benefits.
7.4.2.7. Payback Year: The year in which the cumulative revenue or savings generated by
a project is expected to equal its investment costs.
7.4.3. As a minimum, a present value comparison must be included for all analyses that are
required by AFI 65-501 for which the period of analysis is greater than one year. (T-2).
7.4.4. A narrative explanation and comparison of the benefits is a minimum requirement for
all analyses. (T-2).
7.4.5. See attachments for specific requirements related to special analyses.
7.4.6. As part of interpreting the results, the analyst should provide insights and conclusions
based on the comparison of alternatives.
7.5. If the analyst provides a recommendation: Then the rationale behind the recommendation
must be explained. (T-2).
7.6. The decision-maker at each level may: Want to include a memo with the comparative
analysis that indicates the selected alternative.
7.7. Documentation Requirements. Comparative analyses must be thoroughly documented.
(T-2).
7.7.1. A key element of credible analysis is sufficient documentation of method and
information sources so that, with the same material, a reader not familiar with the study could
arrive at essentially the same result without having to look elsewhere for any information used
to perform the analysis. The documentation in a comparative analysis must meet this standard.
(T-2).
52 AFMAN65-506 6 SEPTEMBER 2019
7.7.2. A comparative analysis is documented in a comparative analysis report. If supporting
documents are too voluminous for inclusion in the comparative analysis report, they must be
cited in sufficient detail so that the exact document(s) may be found by an independent
reviewer or reader if they need to reference them. (T-2).
7.7.3. See paragraph 1.2 for elements to include in the documentation.
7.7.4. Analyses involve calculations or adjustments used to turn raw source data into
information used in the analysis. Since these calculations are commonly done in Excel®, or
specialized estimating software, the files should be retained by the analyst with the
documentation.
7.8. Information and Activities that are Important for Implementing a Decision
7.8.1. While decision implementation is the responsibility of the functional organization for
which the decision is being made (or its implementing partner), there are aspects of the
comparative analysis which may be helpful for implementation and change management.
7.8.2. Implementation Plan In building a comparative analysis, the analyst needs to
understand the assumed schedule and end state of the selected alternative. In fact, the
requirement to cost out the transition and end state often brings more rigor into the planned
alternatives. As such, the plan used in the analysis process to estimate costs could also be used
to build the framework of the implementation plan.
7.8.3. Stakeholder Analysis Information gathered from stakeholders during the comparative
analysis process may be helpful in building a stakeholder action plan and communication plan
needed to implement the alternative selected by the decision-maker. In particular, the benefit
analysis and uncertainty analysis processes may identify stakeholder perspectives and/or
concerns with each alternative.
7.8.4. Performance Measures and Outcomes The cost, benefit, and uncertainty measures
from the comparative analysis provide a framework from which performance measures and
outcomes can be developed. These performance measures and outcomes could be used as a
baseline against which the results of the change are compared and as a starting point for lessons
learned.

Automated Information SystemSee DoDI 5000.02 Table 1 Note 4. A system of computer
hardware, computer software, data or telecommunications that performs functions such as
collecting, processing, storing, transmitting, and displaying information. Exclusions are computer
resources, both hardware and software, that are (1) an integral part of a weapon or weapon system;
(2) used for highly sensitive classified programs (as determined by the Secretary of Defense); (3)
used for other highly sensitive information technology (IT) programs (as determined by the DoD
CIO; or (4) determined by the DAE or designee to be better overseen as a non-Acquisition
Information System program (e.g., a program with a low ratio of RDT&E funding to total program
acquisition costs or that requires significant hardware development).
Base YearUsually defined as the FY in which a program was/will be initially funded.
BenefitsMeasures of an alternative's non-monetary value to the United States Government. The
only benefit measured in terms of dollars is a reduction in some future resource requirement which:
(a) has not been included in an approved (funded) Air Force program or function within the Future
Years Defense Program, and (b) would not be reasonably assumed to be included in an Air Force
approved program beyond the Future Years Defense Program. See Chapter 5.
AFMAN65-506 6 SEPTEMBER 2019 57
Benefits AnalysisAnalysis to identify, measure and evaluate the non-monetary benefits for each
proposed alternative.
Business Case AnalysisSee Comparative Analysis
Clinger-Cohen Act ComplianceRequirement for all programs that acquire information
technology (IT), including National Security Systems (NSS), at any Acquisition Category (ACAT)
level, that the Milestone Decision Authority not initiate a program or an increment of a program,
or approve entry into any phase of the acquisition process that requires formal acquisition
milestone approval, and that the DoD component not award a contract for the applicable
acquisition phase until the sponsoring DoD component or Program Manager has satisfied the
Clinger Cohen Act requirements. The Milestone Decision Authority and Component Chief
Information Officer (CIO), or designee, approve Clinger Cohen Act compliance
Comparative AnalysisAn impartial analysis that uses the economic analysis approach to
support a decision on how to allocate scarce resources. A comparative analysis identifies
alternative methods of solving a problem or accomplishing a stated objective, and compares them
by weighing the costs, benefits, and uncertainties for each alternative. Comparative analyses are
referred to by a variety of names including, but not limited to, economic analysis, business case
analysis, cost benefit analysis, lease vs. purchase, and analysis of alternatives.
Comparative Analysis ProductThe document produced through the process of performing a
comparative analysis. It identifies the competing alternatives for solving a problem or
accomplishing a stated objective, and presents the costs, benefits and uncertainties for each
alternative. It interprets the results of the comparative analysis and highlights aspects in favor of
and against each alternative. It can include a recommendation, but one is not mandatory.
Constant Year DollarThe value or purchasing power of a dollar in any specific year, which
may or may not be the base ear. Constant year dollars do not contain any inflationary changes that
occurred or are forecast to occur outside of the reference year to which the analyst is normalizing.
Constant year dollars are not influenced by outlay profiles (Expenditure Patterns). Also known as
real dollars.
ConstraintsLimitations of any kind to be considered in planning, programming, scheduling,
implementing or evaluating programs, projects, initiatives, etc.
Cost AvoidanceAreas where someone may think the budget will be affected when, in fact, it
will not be. There are two categories of cost avoidance. The first category is productivity gains
that do not result in budget savings such as man hour savings that do not result in a deleted position.
The second category is a reduction in some future resource requirement which: (a) has not been
included in an approved (funded) Air Force program or function within the Future Years Defense
Program and (b) would not be reasonably assumed to be included in an Air Force approved
program beyond the Future Years Defense Program.

Defense Business SystemSee DoDI 5000.75, Business Systems Requirements and Acquisition.
Business systems are information systems that are operated by, for, or on behalf of the Department
of Defense, including: financial systems, financial data feeder systems, contracting systems,
logistics systems, planning and budgeting systems, installations management systems, human
resources management systems, and training and readiness systems. A business system does not
include a national security system or an information system used exclusively by and within the
defense commissary system or the exchange system or other instrumentality of the DoD conducted
for the morale, welfare, and recreation of members of the armed forces using non-appropriated
funds.
Delta EstimateA cost estimate that includes only the costs that are different from the funded
status quo.
Discount RateThe interest rate used to translate future costs or benefits into Present Value. It
is a measure of the time value of money.
DiscountingThe process of using the discount rate to determine the present value of costs.
Economic AnalysisA systematic approach to the problem of choosing how to use scarce
resources to meet a given objective. It includes consideration of costs, benefits, and uncertainties
associated with all alternatives under consideration. At times, the term economic analysis is used
in reference to the product/document that results from applying the economic analysis systematic
approach. This resulting document is also referred to as a comparative analysis product.
Economic Analysis DocumentSee Comparative Analysis Product.
Economic LifeThe period of time over which the benefits to be gained from a project may
reasonably be expected to accrue. It is the shortest of physical, technological or mission life.
EffectivenessAbility of a project to meet objectives.
EfficiencyThe amount of output per unit of input. Alternatively, it is the quality whereby one
alternative uses less input per unit of output than other alternatives.
Feasible AlternativeAn alternative that is considered practical and realistic to execute by
someone familiar with the conditions surrounding the project. A feasible alternative will satisfy
the minimum performance necessary to meet the objective.
Formalized Comparative AnalysisA comparative analysis which satisfies the following
criteria: 1) All of the elements of the economic analysis approach are included; 2) The analysis is
documented from the sources of the raw data, through the interim calculations to the final
conclusions so that a reader would be able to reach the same conclusions using only the information
in the document; 3) The analysis is certified when required by AFI 65-501 and in accordance with
AFMAN 65-506; 4) The analysis includes a comparison of final costs expressed in present value
dollars.
Historical CostThe cost of any item, based on actual dollar (or equivalent) outlay, ascertained
after the fact.
Incremental CostThe change in cost that results from an alternative being selected.
Induced CostsThose costs that execution of a given project or program alternative impose on
another Air Force or government program.
AFMAN65-506 6 SEPTEMBER 2019 59
Investment CostsCosts associated with the acquisition of equipment, real property,
nonrecurring services, nonrecurring operations and maintenance (start-up) costs, and other one-
time outlays. Commonly investment costs are broadly referred to as any costs in the RDT&E and
Procurement Appropriations. For the purpose of a comparative analysis, the implementing
investment costs are those costs that are those initial investment costs (e.g., land purchase,
architectural design, facility construction) required to build the product (e.g., facility) under
evaluation. For clarity, the savings to investment ratio and the internal rate of return use the term
implementing investment.
Lease-Purchase AnalysisAn analysis of the decision whether to lease or purchase the services
of an asset. After the decision to acquire the services of an asset has been made, there may be a
need to analyze the decision whether to lease or purchase the asset.
Life-Cycle CostThe total cost to the government for a system over its full life, including the
cost of development, procurement, operation, support, and disposal.
Mission LifeThe estimated number of years that the need for an asset is anticipated before the
mission either changes or is no longer required.
National Security System (NSS)See US Code Title 40 Subtitle 3 Section 11103. A
telecommunications or information system operated by the Federal Government, the function,
operation, or use of which: (A) involves intelligence activities; (B) involves cryptologic activities
related to national security; (C) involves command and control of military forces; (D) involves
equipment that is an integral part of a weapon or weapons system; or (E) subject to paragraph (2),
is critical to the direct fulfillment of military or intelligence missions.
Non-monetary BenefitBenefit whose value is not represented as cash flow within the analysis.
Nonrecurring Costs - One-time costs or costs that are not expected to continue beyond the
investment phase.
Objective StatementA statement of what a project or program seeks to accomplish. In
economic analysis, objectives are to be stated such that there is no bias toward a particular
alternative.
Opportunity CostThe cost of a resource, measured in terms of its value in the highest alternate
use.
OutputGoods and services produced or provided.
Physical LifeThe number of years an asset can physically be used before it wears out.
Present ValueThe value today of a future amount or series of future amounts, discounted to
reflect the time value of money. Present value comparisons are used in economic analysis to
meaningfully compare different cash flows.
Program EvaluationEconomic analysis of ongoing actions to determine how well the stated
objectives are being accomplished. Program evaluation studies entail a comparison of actual with
intended performance.
Qualitative BenefitBenefit not naturally measured in quantities. These benefits are usually
subjective in nature.
60 AFMAN65-506 6 SEPTEMBER 2019
Quantitative BenefitNon-monetary benefit which can be measured quantifiably. These
benefits are usually objective in nature.
Real PropertyLand, buildings, structures, utility systems, improvements. Includes equipment
attached to and made part of buildings and structures (such as heating systems) but not movable
equipment (such as plant equipment).
Reasonable AlternativeAlternatives that a reasonable person (who is unfamiliar with the
detailed unique circumstances of the analysis) would consider as a potential solution to the
objective. Unreasonable alternatives do not need to be addressed in an Economic Analysis.
Recurring CostsExpenses incurred on a repeated basis, either annually or periodically.
Residual ValueThe expected value of an asset at any point in time before the end of its
economic life.
RiskThe probability of a loss or injury.
SavingsThe reduction of required funding for a currently approved (funded) program or
function, within the time period covered by the Future Years Defense Program. Additionally,
when the same type of reduction that would have led to a reduction within the Future Years
Defense Program occurs beyond the Future Years Defense Program period, these reductions are
also savings because they are reducing cost for a program or function that is assumed to be
approved (funded). A reduction in monetary cost from the approved and funded Status Quo (i.e.,
baseline) alternative is considered savings. Savings result from the cost analysis and should be
discussed in the Comparison of Alternatives
Sensitivity AnalysisExamination of the effects obtained by changing the direction and
magnitude of assumptions, key variables or other factors in an analysis.
Sunk CostSum of past expenditures or irrevocably committed funds related to a project. Such
costs are generally not relevant to decision making as they reflect previous, rather than present,
choices.
Technological LifeThe estimated number of years before improved technology will make an
existing or proposed asset obsolete.
Terminal ValueThe expected value of assets at the end of their economic life.
Then-Year DollarReflects the amount of funding needed (expected to be needed) when the
expenditure for goods and services were (are expected to be) made. Then-year dollars include
inflation and escalation.
UncertaintyThe indefiniteness about the outcome of a situation. Uncertainty includes both
risks (i.e., the probability of a loss or injury) and opportunities (i.e., favorable events or outcomes).
Uniform Annual CostThe average cost per year for a given alternative. It is calculated by
dividing the total net present cost (for the full-time life cycle) by the sum of the discount factors
of the years in which benefits accrue (economic life).
Wash (Common) BenefitAny benefit that will be incurred identically across alternatives.
Wash (Common) CostAny cost that will be incurred identically across alternatives.

COMPARATIVE ANALYSIS CERTIFICATION AND WAIVER APPROVAL
A3.1. Introduction.
A3.1.1. Comparative Analysis Certification is the Air Force’s standardized method of
assuring comparative analyses are completed in accordance with the instructions outlined in
AFI 65-501 and this manual, and that both functional and financial management reviewers at
each stage of the review coordinate on the assumptions made and techniques used to produce
the analysis results.
A3.1.2. Certification must follow the format and certification process in this Attachment, and,
at a minimum, incorporate all statements and information included in this Attachment unless
excepted by the criteria A3.1.6 (T-1). Functional managers and reviewers at each stage of the
review process must sign the Certificate of Satisfactory Comparative Analysis. (T-1).
Comparative analyses forwarded to the Air Staff or Secretariat must give evidence of
intermediate levels of certification. (T-1).
A3.1.3. The standup of Air Force Installation and Mission Support Center (AFIMSC) in 2015
as Air Force Materiel Command’s sixth center, created a gap in Air Force comparative analysis
certification policy. This realignment in conjunction with a Headquarters reduction left some
MAJCOMs without the ability to adequately review and certify comparative analysis
documents developed within their MAJCOM. As a result, command financial management
offices now have the option of forming a memorandum of understanding with the Air Force
Materiel Command financial management cost office to certify their comparative analyses.
See AFI 65-501, paragraph 1.4.4.
A3.1.4. The Waiver Approval process is the Air Force’s standardized method of determining
if a project or program that would normally require a comparative analysis in accordance with
AFI 65-501, paragraph 1.5, can be exempted due to meeting the criteria outlined in AFI 65-
501, paragraph 1.6. The Waiver Approval process requires all functional and Financial
Management (FM) offices to coordinate on (i.e., agree with) the initiating office’s claim that
the project or program meets the criteria outlined in AFI 65-501, paragraph 1.6.
A3.1.5. Waiver Approval must follow the coordination process in this Attachment. (T-1). The
format of the “Request for Waiver from a Comparative Analysis” form is in Attachment 4.
Functional and financial managers and reviewers at each stage of the review process must sign
the Request for Waiver from a Comparative Analysis. (T-1). All waiver requests must be
forwarded to the Air Staff or Secretariat for final forwarding to, and approval by, SAF/FMCE.
(T-1).
A3.1.6. Applicability
A3.1.6.1. The requirement for certification applies to comparative analyses required by
AFI 65-501, paragraph 1.5.
A3.1.6.2. The process for certifying comparative analyses detailed in this Attachment
applies to most types of comparative analyses. However, processes can vary depending on
the type of program or funding.
64 AFMAN65-506 6 SEPTEMBER 2019
A3.1.6.2.1. The process for certification described in this chapter does not apply to
Clinger-Cohen Act comparative analyses done for programs on the acquisition master
list or with other acquisition designations, (e.g., Middle Tier of Acquisition Programs).
For these programs, see Attachment 12 to this manual.
A3.1.6.2.2. Certification of Product Support Business Case Analyses is accomplished
through the governance approval process specified in Air Force Pamphlet 63-123.
A3.1.6.2.3. If unsure of the process, the financial management office developing the
comparative analysis should consult with the MAJCOM financial management office
of primary responsibility to determine the appropriate process.
A3.1.6.3. The approval process for comparative analysis waivers allowed in accordance
with AFI 65-501, paragraph 1.6, follows many of the same steps as the process for
comparative analysis certification.
A3.2. Roles and Responsibilities Table A3.1 below highlights the key roles and
responsibilities for the Comparative Analysis Certification Process. Table A3.2 shows the key
roles and responsibilities for the Comparative Analysis Waiver Approval Process.

Responsibilities.*
A3.3. Meaning of Certification with respect to a Comparative Analysis
A3.3.1. Certification by financial management personnel means that a comparative analysis
has been prepared in accordance with this manual and AFI 65-501. Certification by financial
management personnel attests to the reasonableness of the data in the comparative analysis,
the proper use of economic principles in the analysis and the adequacy of documentation such
that the comparative analysis is a stand-alone document. All factors and data in the
comparative analysis must be current as of the signing of the certification. Certification by
financial personnel does not mean that the financial organization endorses the conclusions
contained in the comparative analysis.
A3.3.2. Certification by functional personnel indicates that the assumptions, reasoning and
cost and benefit assessments in the comparative analysis are consistent with their area of
technical expertise. Certification does not mean that the functional organization endorses the
conclusions contained in the comparative analysis.
AFMAN65-506 6 SEPTEMBER 2019 67
A3.4. Meaning of Coordination with respect to a Request for Waiver from a Comparative
Analysis
A3.4.1. Coordination on a request for waiver from a comparative analysis by functional and
financial management personnel means that the project or program meets the criteria outlined
in AFI 65-501, paragraph 1.6, and the specific reason(s) on the “Request for Waiver from a
Comparative Analysis” form selected by the initiating office is valid.
A3.4.2. Coordination on a waiver request also means that clear and convincing justification
for the reason(s) selected are included in the waiver request package.
A3.5. Process Description
A3.5.1. Entrance Criteria to the process The Comparative Analysis Certification Process and
the Request for Waiver from a Comparative Analysis Process are initiated in accordance with
AFI 65-501 and based on one of the following criteria:
A3.5.1.1. There is a requirement for a comparative analysis to be certified
A3.5.1.2. There is a requirement for a comparative analysis with justification for a waiver
to be approved.

Does the comparative analysis/waiver request require
Headquarters Air Force certification/approval?
All waiver requests require HAF approval.
Certain comparative analyses require HAF certification because the
analysis has visibility at the level of the Secretary or Under Secretary
of the Air Force or the Chief of Staff or Vice Chief of Staff of the Air
Force. A comparative analysis also requires HAF certification if the
analysis is anticipated to have an audience outside of the AF.
Additionally, comparative analyses initiated at the MAJCOM or

Attachment 5
COMPARATIVE ANALYSIS PREPARER’S GUIDE
A5.1. This is a guide for preparers of comparative analyses. It is intended to assist in
performing a comparative analysis. It is like a checklist, but the intention is for it to go beyond
the mere listing of items that must be included in the comparative analysis document. It provides
a narrative description of the thought processes behind performing a comparative analysis, and is
organized consistent with the organization of a comparative analysis so the preparer can use it as
an outline when developing and documenting the comparative analysis.
A5.2. What is a Comparative Analysis?
A5.2.1. A comparative analysis is a decision analysis that identifies alternatives and presents
defendable economic and technical arguments (to include costs, benefits, and uncertainty) for
and against each alternative leading to an assessment of each alternative’s ability to achieve
stated objectives and the associated costs.
A5.2.2. Names for comparative analyses include Economic Analysis, Business Case Analysis,
Cost-Benefit Analysis, Capability Analysis, and Analysis of Alternatives, among others.
Figure A5.1. Format of a Comparative Analysis.
A5.3. Certificate of Satisfactory Comparative Analysis: This is the first page of a typical
comparative analysis package. It should follow the format shown in the sample Certificate of
Satisfactory Comparative Analysis at the end of Attachment 3. In the Certificate:
AFMAN65-506 6 SEPTEMBER 2019 77
A5.3.1. Each FM certifier must certify that the comparative analysis complies with the guiding
regulations (AFI 65-501 and AFMAN 65-506) and that it reasonably reflects the costs and
benefits of the alternatives presented.
A5.3.2. Each Functional OPR certifier must certify that the assumptions, reasoning and
functional technical assessments in the comparative analysis are sound and are consistent with
their functional area of technical expertise.
A5.3.3. Make sure that: The certificate follows the format shown in the sample Certificate of
Satisfactory Comparative Analysis at the end of Attachment 3.
A5.3.3.1. It states the Installation name, MAJCOM, and Project Title. If the project has a
Project Number (e.g., MILCON economic analyses), it should be included, as well.
A5.3.3.2. It states all feasible alternatives that were considered in the analysis.
A5.3.3.3. It includes this statement, which describes what the FM certifier is certifying
about the analysis: “This comparative analysis follows the instructions in AFI 65-501and
the procedures in AFMAN 65-506. Significant changes to project scope, major
assumptions, or estimated costs will invalidate this certificate and require revision of this
analysis.”
A5.3.3.4. It also includes this statement, which describes what the Functional certifier is
certifying about the analysis: “The assumptions, reasoning, and functional technical
assessments in this comparative analysis are sound with respect to the function
implementing this program/project.”
A5.3.3.5. There are signature blocks for the installation Financial Management Analysis
(FMA), FM, and Functional office. For simple administrative reasons, it may be simpler
to do MAJCOM certification on a separate certificate, but if not, the certificate should have
signature blocks for MAJCOM FM and functional offices. Signatures for other offices
should be included as applicable to the analysis.
A5.4. Executive Summary: The Executive Summary briefly summarizes the comparative
analysis and its results.
A5.4.1. It should follow the format in Attachment 2.
A5.4.2. For additional guidance on a Real Property Construction and Repair Analysis
executive summary, see Attachment 11.
A5.5. The Objective: The objective should state the requirement each alternative must meet.
Make sure that:
A5.5.1. The objective stated is the objective of the program or project, not of the comparative
analysis. It should state the requirement that each alternative is designed to fulfill, like The
objective is to provide family housing that meets Air Force standards to 350 military families
at Yodel AFB.” Note that the objective in this example should not be to conduct a comparative
analysis on military family housing. The objective revolves around what the analyst is trying
to obtain or accomplish.
78 AFMAN65-506 6 SEPTEMBER 2019
A5.5.2. The objective stated addresses the root problem. Seeking solutions to the wrong
problem, or a poorly stated problem, often leads to the wrong solution due to missed
alternatives, faulty assumptions, etc. Pictorial displays of processes or data (e.g., a flow chart)
can assist in ensuring a complete understanding of the problem.
A5.5.3. The objective stated is not so narrow that it eliminates reasonable alternatives.
A5.5.4. The objective is not slanted in such a way that the comparative analysis that follows
naturally leans towards preferring any particular alternative (also known as “pre-selection
bias”), nor does it unreasonably rule out others.
A5.6. Facts, Ground Rules, and Assumptions: Make sure that:
A5.6.1. Facts are documented and sources are provided.
A5.6.2. Assumptions are not used in place of discoverable facts.
A5.6.3. All assumptions are reasonable and not too restrictive. Do not use assumptions that
unduly restrict the study by eliminating possible significant alternatives or by narrowing the
scope of consideration. Likewise, assumptions should not unfairly penalize one or more
alternatives. If there is any question, include a brief explanation about why each assumption
was made.
A5.6.4. The period of analysis is consistent with the type of analysis.
A5.6.5. The most recent discount rates are used.
A5.6.6. The most recent applicable inflation rates are used.
A5.6.7. Applicable/appropriate escalation indices are used to normalize and forecast costs.
A5.6.8. There is a ground rule about the type of dollars used in the document (e.g., FY19
constant year dollars).
A5.6.9. There are assumptions about economic life, depreciation, and residual value.
A5.6.10. Assumptions made in the analysis can reasonably be expected to represent the most
likely condition, and are properly supported.
A5.6.10.1. When an assumption is given a value in the analysis, ensure the baseline value
is reasonable and not too optimistic or pessimistic.
A5.6.11. The analysis does not assume away costs, especially significant ones. If minor costs
are assumed away, include a reasonable explanation.
A5.6.12. Assumptions are examined to determine if they should be included in the Uncertainty
Analysis. Assumptions impose a limitation or a judgment. It is important to assess the impact
of limitations and judgments contained in significant assumptions. Uncertainty analysis
examines the effect that major uncertainties in assumed values have on analysis results.
A5.7. Alternatives: This section of the comparative analysis should list and describe all
reasonable methods of satisfying the objective. Make sure that:
A5.7.1. All reasonable alternatives are discussed. It is important to discuss all seemingly
reasonable alternatives even if some are subsequently determined to be infeasible. That way,
later readers/reviewers will know that all reasonable alternatives were considered.
AFMAN65-506 6 SEPTEMBER 2019 79
A5.7.2. All alternatives determined to be infeasible have a convincing explanation as to why
that is the case. Explain how the determination of infeasibility was arrived at. The explanation
should assume the reader is not familiar with the project or program, or the location at which
the project or program will be implemented. Infeasible alternatives are not analyzed any
further after this point.
A5.7.3. Alternatives are sufficiently different from each other as opposed to a superficial
restructuring of a single course of action.
A5.7.4. Contract and other government agency alternatives are considered where reasonable.
A5.7.5. The status quo is used as a baseline for alternative evaluation where possible.
A5.7.6. The explanation of each alternative describes what would have to be done to
implement the alternative if it were to be selected, and that the explanation is written as if the
reader were unfamiliar with the project. Make sure that all aspects of the alternative that
differentiate it from other alternatives in ways that influence costs and benefits are adequately
described.
A5.7.6.1. Use the standard that the descriptions should not leave readers/reviewers
confused over why certain costs or benefits are included in some alternatives, but not
others.
A5.7.6.2. For example, when a Supply Warehouse comparative analysis includes
acquisition costs for new material handling equipment in Alternative 2 but not any other
alternatives, the description of Alternative 2 should explain the reason, such as this
equipment is required only if the warehouse function were to relocate to a different facility,
due to the different configuration of that facility.
A5.7.7. When faced with an environment where key variables in the analysis are changing, or
are expected to change in the near future, these changes are incorporated into the base case. In
this situation, the analysis may include just this “revised” base case, or both a status quo
without the changes and a base case with the changes.
A5.7.8. All significant interfaces with existing systems or projects are adequately considered
in developing the alternatives. Proper treatment of alternatives requires careful examination
of how the proposed alternatives affect and are affected by related systems or projects. This
examination is crucial in areas such as transportation and management information systems.
A5.7.9. Combinations of Systems or Projects are considered among the alternatives. Consider
viable alternatives based on mixtures of two or more efforts that combine the best features of
each. For example, in a management information system analysis, one alternative might be a
manual system and another might be an automated system. If feasible, a third might be a
combination of a manual and an automated system.
A5.8. Cost Analysis: This section of the comparative analysis describes the cost estimating
methodologies used in the analysis and presents the costs and revenues, as applicable, for each
alternative. Make sure that:
A5.8.1. The costs and revenues are labeled with their type of dollars as well as the associated
FY (e.g., then-year FY18 dollars, FY12 constant dollars). Check that all totals and other
calculations are completed with the same type of dollars.
80 AFMAN65-506 6 SEPTEMBER 2019
A5.8.2. Each alternative’s costs and revenues are, as a minimum, reported in present value
dollars. The report may also include reporting in other types of dollars.
A5.8.3. Revenue estimates are based on realistic assumptions, are computed in the same type
dollar as any costs in the same alternative and have realistic phasing.
A5.8.4. If part of the analysis report identifies funding required by FY in order to facilitate
budget preparation, those dollars are presented in then-year dollars for that section of the
analysis and analysis report.
A5.8.5. Investment costs and recurring costs are properly categorized.
A5.8.6. The costs and revenues for each alternative are estimated as if that alternative was
actually going to be implemented, and ALL relevant costs and revenue that are incremental to
the decision are included. Exceptions are noted in paragraphs A5.8.1.13 and A5.8.1.14.
A5.8.7. Direct and indirect costs all have been considered and included, as appropriate.
A5.8.7.1. Ensure the level and details of costs in the analysis provide enough information
for the decision maker.
A5.8.7.2. Ensure costs and related estimating techniques are adequately described and the
alternatives remain comparable even when different estimating techniques are used for
each alternative.
A5.8.7.3. Items determined to be cost avoidance are not included in the cost analysis. For
example, productivity improvements sometimes lower costs and results in savings when
compared to other alternatives, but sometimes productivity improvements result in cost
avoidances, not savings. If an alternative is estimated to save 100 hours per year, but no
manpower positions would be eliminated, then the manpower costs are not reduced. In
this situation, productivity improvements are cost avoidance benefits and are captured as
hours in the Benefits Analysis section.
A5.8.7.4. Cost avoidance also includes a reduction in some future resource requirement
which: (a) has not been included in an approved (funded) Air Force program or function
within the Future Years Defense Program, and (b) would not be reasonably assumed to be
included in an Air Force approved program beyond the Future Years Defense Program.
These cost avoidances are also not included in the cost analysis. They are incorporated
into the benefit analysis.
A5.8.8. All discounting calculations are correct.
A5.8.8.1. As required by paragraph 4.5.7.4.1, use midyear discount factors (vice End-of-
Year factors).
A5.8.8.2. Any use of End-of-Year or other factors should be explained in the Assumptions
section.
A5.8.9. Appropriate inflation and cost escalation indices are used, and that they are applied
properly. AFMAN 65-502 provides information on how to appropriately make these
adjustments.
A5.8.10. The time phasing of cash flows is realistic.
A5.8.11. Cost collection aggregation and normalization is reasonable.
AFMAN65-506 6 SEPTEMBER 2019 81
A5.8.12. Confidence levels are reported for any cost estimate that assessed cost risk. If cost
risk was assessed in the estimate for one alternative, cost risk is included for other alternatives,
where appropriate, and all alternatives are evaluated at similar confidence levels.
A5.8.13. Common costs are treated the same for all alternatives. These costs need not be
included in the comparative analysis. Since these costs are common to all alternatives, there is
no value added to comparing them across alternatives, although there is no problem with
including them, and for obvious cost items, they often are. Later readers (e.g., Commanders,
reviewers) may wonder why there is no cost for an obvious cost element when they read the
comparative analysis.
A5.8.14. Only differential costs are included if the cost estimate is a delta estimate. To avoid
confusion for those readers who may be unfamiliar with this concept, its use should be
explained as a ground rule and in the cost section. If there are multiple alternatives, the
differential costs should all be taken from the same reference point, typically the status quo.
A5.8.15. Sunk costs are not included in the analysis. These costs will be incurred regardless
of any decision the decision-maker makes. The purpose of comparative analyses is to help
decision-makers make choices about resource allocation, and any costs beyond the control of
the decision-maker should not play a part in the decisions.
A5.8.16. Costs incurred in foreign currency are converted at the known or estimated exchange
rate of the base year of the analysis, NOT the Foreign Currency Fluctuation Account budget
rate. Include an explanation of the exchange rate being used and its source. The Assumptions
section is a typical location for this explanation.
A5.9. Benefit Analysis: This section of the comparative analysis identifies, measures, and
evaluates the non-monetary benefits of the proposed alternatives. Make sure that:
A5.9.1. The Benefits Analysis includes all non-monetary benefits.
A5.9.1.1. Generally speaking, only non-monetary benefits are included in this section.
The only benefit measured in terms of dollars is a reduction in some future resource
requirement which: (a) has not been included in an approved (funded) Air Force program
or function within the Future Years Defense Program, and (b) would not be reasonably
assumed to be included in an Air Force approved program beyond the Future Years
Defense Program.
A5.9.1.2. Reduced costs and increased revenues are included in the Cost Analysis.
Although these are positive, beneficial attributes, they are monetary in nature and are not
addressed in the Benefit Analysis.
A5.9.1.3. Any items identified as cost avoidance are included in the Benefit Analysis and
not included in the Cost Analysis.
A5.9.2. Benefits primarily relate to the project objective. There may also be ancillary benefits
gained from a particular alternative. These ancillary benefits can be recognized in the analysis,
but should be secondary to those benefits that are directly related to the project objective.
A5.9.3. Benefits realized in the past are not included in the analysis. Similar to sunk costs,
these have already been received and the decision cannot change that.
82 AFMAN65-506 6 SEPTEMBER 2019
A5.9.4. Benefits are clearly defined and that they are mutually exclusive. The analysis should
not double count anything. To avoid double counting, review benefits to ensure they are not
already captured in another benefit or in the Cost Analysis.
A5.9.5. A weighting system is used if all benefit measures are not of equal importance in the
analysis/decision. A weight system adjusts the level of impact each benefit has on the analysis.
A5.9.6. Quantitative benefits are included in the analysis in the units in which they naturally
occur, unless they are converted to percentages.
A5.9.7. Benefit measuring techniques are properly defined and supported.
A5.9.7.1. Ensure that prioritization (i.e., weighting) of benefits is logical and consistent.
A5.9.7.2. For any scored benefits, ensure the scoring approach is applied consistently
across alternatives and the assigned scores are reasonable.
A5.9.8. The timing of the benefits is considered for future systems. The benefits of a proposed
future system often depend on when it will be available for operational use and the total
operational life span (economic life) of the system. In examining the effect of the time
dimension on benefits, pay particular attention to the time between the present and the initial
operational availability of the complete system.
A5.9.9. The impact of other operations are considered. Sometimes the system or organization
interfaces with other systems or organizations to the point where its operations affect and are
affected by the operations of the other. For example, peak use of power, or vehicles, or people
may have detrimental effects on related projects or activities. Consider the “ripple effect.”
A5.9.10. If risk elements are analyzed (see section 6.3.2 of this manual) and are analyzed as
part of the benefits analysis, ensure their treatment is consistent with the treatment of other
benefits to the maximum extent possible. If consistent treatment is not possible, (e.g., risk
assessment is narrative while other benefits are quantified), explain how the risk elements are
to be evaluated in the overall benefits analysis.
A5.10. Uncertainty Analysis, Including Sensitivity Analysis and Risk: An Uncertainty
Analysis includes a Sensitivity Analysis and may include a Risk Analysis. A Sensitivity Analysis
tests the effect that uncertain assumptions have on the results of the alternatives relative to each
other. A Risk Analysis evaluates risk to program execution (cost, schedule, performance) and risk
to the Air Force for each alternative. Make sure that:
A5.10.1. A sensitivity analysis is performed on all assumptions that have a great deal of
uncertainty and a significant impact on analysis results.
A5.10.1.1. For quantitative assumptions, a useful technique is to vary the value of the
assumption across the range of probable values. This type of analysis will show not only
how sensitive results are to changes in the assumption’s value, but should also reveal the
nature of the relationship between the assumption’s value and analysis results (e.g., linear,
exponential).
A5.10.1.2. For qualitative assumptions, a useful technique is to try to make other plausible
major assumptions. If these invalidate the study’s results, then the results are not robust in
this area. Ensure this is discussed in the analysis.
AFMAN65-506 6 SEPTEMBER 2019 83
A5.10.2. A sensitivity analysis is considered for all cost elements that constitute a high
percentage of total life cycle costs. Similarly, ensure a sensitivity analysis is considered for
benefits with a large relative weight.
A5.10.3. If the benefits derived in the analysis depend on the assumptions, some consideration
has been made to determine the degree of dependence. Generally a good analysis will show
the degree of dependence through various kinds of sensitivity analyses.
A5.10.4. If the PVs of the two lowest-cost alternatives are close, a sensitivity analysis is
performed on the most uncertain assumption(s) of the alternatives, and if it shows a change in
the cost ranking of alternatives, this should be pointed out in the Summary and Comparison of
Alternatives section. Identify the crossover points for each assumption.
A5.10.5. Scenario analysis is considered if the decision-maker would benefit from the
information gained by analyzing changes to multiple variables simultaneously or if a change
in one variable almost always impacts a different variable and they should be examined
together.
A5.10.6. The comparative analysis describes what was done in the Sensitivity Analysis and,
at least briefly, state its results. Do not just rely on graphs and charts. Explain what they mean.
A5.10.7. The study includes adequate sensitivity analyses in light of the time and resources
allotted to the study, the magnitude of the proposed investment, and the likelihood additional
analyses would significantly affect the study results. At the minimum, assumptions with
uncertainty and a large effect on analysis results and variables comprising a large percentage
of costs should be considered for a Sensitivity Analysis.
A5.10.8. A risk analysis is included, if warranted.
A5.10.8.1. Is there reason to believe that the level of risk associated with any alternative
will likely be a key consideration for the decision-maker?
A5.10.8.2. Is significant execution risk (i.e., cost, schedule, or performance) associated
with the alternatives?
A5.10.8.3. Did the decision-maker direct a risk assessment?
A5.10.8.4. Is there significant uncertainty associated with the assumptions in the benefits
analysis?
A5.10.9. If a risk assessment is included:
A5.10.9.1. Adequately explain the risks.
A5.10.9.2. Ensure subject matter expertise underlies the risk assessment.
A5.10.9.3. Only assess political risk if the requirements of section 6.3.7 are met.
A5.10.9.4. If risk mitigation measures are assumed when assessing the risk of an
alternative, include the costs of those mitigation measures in the cost analysis.
A5.10.9.5. Include elements rated as zero risk in the overall assessment of risk unless they
are common among all alternatives. Leaving those elements out biases the risk assessment.
A5.10.9.6. Include the risk assessment results in the Summary and Comparison of
Alternatives.
84 AFMAN65-506 6 SEPTEMBER 2019
A5.11. Summary and Comparison of Alternatives: This is where the analyst summarizes the
results of the Cost Analysis, Benefit Analysis, and Uncertainty Analysis for each alternative
compares the strengths and weaknesses of each alternative with respect to the other alternatives,
and explains the implications of the results. Make sure that:
A5.11.1. Summary tables for the cost analysis, benefit analysis, and uncertainty analysis are
provided for areas where analyses have been expressed in quantitative terms.
A5.11.2. Analyses expressed in qualitative terms are summarized in narrative form.
A5.11.3. A brief narrative explanation of the summarized cost and benefit data and uncertainty
assessment, as well as any measurements and indicators, is included.
A5.11.4. All criteria for comparison are identified. The criteria, or characteristics of cost,
schedule, and performance, are the bases for the conclusions.
A5.11.5. All criteria are stated clearly. Decisions will likely be based on them.
A5.11.6. Each alternative’s relative strengths and weaknesses are compared.
A5.11.6.1. At a minimum, ensure comparison of the present value of costs and revenues
for all alternatives.
A5.11.6.2. At a minimum, ensure benefits of all alternatives are narratively compared.
A5.11.6.3. Ensure present value calculations and other comparison metrics are
accomplished in accordance with Attachment 7.
A5.11.6.4. Ensure any requirements for special analyses are adhered to (e.g., inclusion of
a return on investment calculation for economic analyses required for Clinger-Cohen Act
certification).
A5.11.7. Ensure the alternative comparison techniques are appropriate for the project being
evaluated.
A5.11.8. Any interpretation in this section is consistent with the interpretation in the Executive
Summary. Sometimes, changes made in one of these do not catch up to the other sections
before the documentation is finalized.
A5.11.9. The rationale behind any recommendation is explained. A recommendation is not
required, but may be provided by the analysis team.
A5.11.10. The analyst/comparative analysis preparer should encourage the decision-maker at
each level to prepare a memo stating which alternative they prefer. All such memos should be
included with the comparative analysis.
A5.12. Attachments & Appendices - Supporting Documentation: This is everything that
serves as the basis for the analysis. Each comparative analysis should be a stand-alone document.
Therefore, it should include copies of source data and all calculations used to turn the source data
into comparative analysis inputs (e.g., normalization calculations). A reviewer should be able to
understand the comparative analysis without having to look at anything else. They should be able
to replicate the comparative analysis using the source data and documentation.
A5.13. This is the end of the Preparer’s Guide. For more assistance in preparing a comparative
analysis, contact the MAJCOM’s FM Office, AFIMSC/RMC, or SAF/FMCE.
AFMAN65-506 6 SEPTEMBER 2019 85
Attachment 6
COMPARATIVE ANALYSIS REVIEWER/CERTIFICATION GUIDE
A6.1. This is a guide for reviewers and certifiers of comparative analyses. It is like a
checklist, but the intention is for it to go beyond the mere listing of items to check. It provides a
narrative description of the thought processes behind a comparative analysis review, and is
organized consistent with the organization of a comparative analysis, so that a reviewer can go
through the guide while going through the comparative analysis. It takes the form of questions,
followed by a brief identification of the issue being highlighted.A6.2 It will help to begin by
describing what a Comparative Analysis is:
A6.2. A comparative analysis is : A decision analysis that identifies alternatives and presents
defendable economic and technical arguments (to include costs, benefits, and uncertainty) for and
against each alternative leading to an assessment of each alternative’s ability to achieve stated
objectives and the associated costs. Names for comparative analyses include Economic Analysis,
Business Case Analysis, Cost-Benefit Analysis, Capability Analysis, and Analysis of Alternatives,
among others.
A6.3. Certificate of Satisfactory Comparative Analysis: This is the first page of a typical
comparative analysis package. It should follow the format shown in the sample Certificate of
Satisfactory Comparative Analysis at the end of Attachment 3.
A6.3.1. There should be signature blocks for the installation FMA, FM, and functional office.
For simple administrative reasons, it may be simpler to do MAJCOM certification on a separate
certificate, but if not, the certificate should have signature blocks for MAJCOM FM and
Functional offices.
A6.3.2. Check to see that all FM and Functional Office OPRs at lower levels have certified
(i.e., signed) the comparative analysis. It should be certified by all FM and Functional Office
OPRs at lower levels before the reviewer assesses the document at the current level.
A6.3.2.1. Each FM certifier certifies that the comparative analysis complies with the
guiding regulations (AFI 65-501 and AFMAN 65-506) and that it reasonably reflects the
costs and benefits of the alternatives presented.
A6.3.2.2. Each Functional OPR certifier certifies that the assumptions, reasoning and
functional technical assessments in the comparative analysis are sound and are consistent
with their functional area of technical expertise.
A6.3.2.3. The FM or Functional reviewer will be expected to certify (i.e., sign) the analysis
when thereview is complete. By doing so, the reviewer will be acknowledging agreement
with either paragraph A6.3.2.1 or A6.3.2.2, depending on whether the reviewer is an FM
certifier or a Functional OPR certifier.
A6.3.3. What to look for: The certificate should:
A6.3.3.1. Follow the format shown in the sample Certificate of Satisfactory Comparative
Analysis at the end of Attachment 3.
A6.3.3.2. State the Installation name, MAJCOM, and Project Title. If the project has a
Project Number (e.g., MILCON economic analyses), it should be stated, as well.
86 AFMAN65-506 6 SEPTEMBER 2019
A6.3.3.3. State all alternatives that were considered in the analysis, even if any of them
were deemed infeasible.
A6.3.3.4. Include this statement, which describes what the FM certifier is certifying about
the analysis: “This comparative analysis follows the instructions in AFI 65-501, and the
procedures in AFMAN 65-506. Significant changes to project scope, major assumptions,
or estimated costs will invalidate this certificate and require revision of this analysis.”
A6.3.3.5. Include this statement, which describes what the Functional certifier is certifying
about the analysis: “The assumptions, reasoning, and functional technical assessments in
this comparative analysis are sound with respect to the function implementing this
program/project.”
A6.4. Executive Summary: The Executive Summary should briefly summarize the comparative
analysis and its results.
A6.4.1. The Executive Summary should follow the format in Attachment 2.
A6.4.2. For additional guidance on a Real Property Construction and Repair analysis
executive summary, see Attachment 11.
A6.5. Objective: The objective should state the requirement each alternative must meet. It is the
reason the project has been proposed. What to look for:
A6.5.1. Does the stated objective address the real problem? Critical to the successful
completion of a comparative analysis is the identification and clear statement of the correct
objective. Often symptoms and not the disease are believed to be the problem. Seeking
solutions to the wrong problem, or a poorly stated problem, almost always leads to the wrong
solution due to missed alternatives, faulty assumptions, etc.
A6.5.2. Is the objective statement too narrow? Does it unnecessarily eliminate reasonable
alternatives?
A6.5.3. Does the objective statement favor one alternative over another?
A6.5.4. Does the objective statement identify all significant pieces of the problem? The
analysis addresses the objective statement. Therefore, the objective statement must fully
identify, consider, and address all facets of the problem. Look for significant problem
components that are not identified and addressed.
A6.6. Facts, Ground Rules, and Assumptions: What to look for:
A6.6.1. Are all assumptions identified? Look for assumptions that are not identified since
assumptions imply a limitation or a judgment. Assessing the impact of limitations and the
validity of judgments contained in all assumptions is necessary. A common assumption,
seldom made explicit, is that a given organization or system operates by itself. Such an
assumption can contribute to inadequate consideration of support provided and complementary
outputs produced by related systems. This can lead to improper measurement of total costs
and benefits and erroneous conclusions. As a minimum, this section should:
A6.6.1.1. Identify facts and their sources.
A6.6.1.2. Include a ground rule about the type of dollars used in the analysis (e.g., FY19
constant year dollars).
AFMAN65-506 6 SEPTEMBER 2019 87
A6.6.1.3. State the inflation and escalation rates used and their sources.
A6.6.1.4. State the discount rates used. They should be the most recent discount rates
published in OMB Circular A-94, Appendix C.
A6.6.1.5. Include assumptions about economic life, depreciation, and residual value.
A6.6.2. Are any assumptions used in place of discoverable facts?
A6.6.3. Are the major assumptions reasonable? All major assumptions should be examined
at each level of review by either a FM or Functional OPR to determine if they are reasonable
with respect to their area of expertise.
A6.6.4. Are the assumptions unduly restrictive? Assumptions, when properly used, narrow
the scope of a comparative analysis to manageable proportions. However, the assumptions
should not unduly restrict the study, thereby eliminating possible significant alternatives or
narrowing the scope of consideration. This examination should continue throughout the review
of the analysis and not only during the initial review of the stated assumptions.
A6.6.5. Do any of the major assumptions incorrectly treat a variable whose value has inherent
uncertainty as a fact?
A6.6.5.1. Uncertainty can be defined as the lack of reliable knowledge to assign values or
probabilities to factors influencing analysis results. Uncertainties can be quantitative or
qualitative.
A6.6.5.2. The reviewer should be alert to major assumptions, either stated or implied,
assigning fixed values to variables subject to uncertainty--the assigned values then being
treated in the analysis as facts.
A6.6.5.3. Examples of quantitative variables that have inherent quantitative uncertainty
are: projected workloads, personnel retention rates, equipment usage rates, and availability
and reliability rates. If a quantitative variable’s value that has inherent uncertainty is
treated as a fact, check to see if the assumption is included in the Uncertainty Analysis
(addressed in Chapter 6). Major qualitative uncertainties treated as assumptions can also
affect results.
A6.6.5.3.1. Examples of variables that have inherent qualitative uncertainty are:
availability of community services, availability of spare part manufacturers, and
advances in technology that lead to new equipment capabilities.
A6.6.5.3.2. Political considerations, such as availability of base rights, assurance of
overflight permission, and the character of future environmental standards are also
examples of qualitative variables with inherent uncertainty, and can sometimes make
the difference between an alternative being feasible or not. Treatment of these kinds
of uncertainties is not easy, but if they are important to analysis results, a good analysis
will address them, even if only narratively. Sometimes these variables’ values can have
a limited number of discrete values (e.g., “yes” or “no”; “low”, “medium” or “high”).
For this type of qualitative variable, the Uncertainty Analysis can show how different
assumptions have an impact on analysis results. A study of alternative waste disposal
systems thus might investigate the effects of increasingly severe environmental
standards and the possible use of improved filtration processes.
88 AFMAN65-506 6 SEPTEMBER 2019
A6.6.5.4. Does the analysis assume away any costs? The analysis cannot simply assume
away costs. A red flag should go up any time a reviewer see something like this. If minor
costs are assumed away, ensure there is a reasonable explanation. Depending on the
reasons given, it may be justified, but ensure it passes the sanity check.
A6.7. Alternatives: This section of the comparative analysis should list and describe all
reasonable methods of satisfying the objective. What to look for:
A6.7.1. Are all seemingly reasonable alternatives considered?
A6.7.1.1. If the reviewer can think of an alternative that could achieve the objective, but
that was not mentioned and discussed in the comparative analysis, then the analysis should
probably be returned for further work. If the alternative is feasible, it should be included
in the analysis. If the alternative is not feasible, it should be mentioned and the reasons for
its infeasibility explained. It is the analyst’s responsibility to state the relevant facts and
explain why the alternative is infeasible.
A6.7.1.2. Are all feasible alternatives analyzed?
A6.7.2. Are current capabilities or the "base case" adequately considered?
A6.7.2.1. Current capabilities should be considered when constructing alternatives except
for clearly stated valid reasons. Valid reasons may include inability of the current system
to accomplish the proposed objective. Current capabilities, where applicable, should also
be considered as part of a proposed alternative.
A6.7.2.2. If the current system is included as an alternative in an analysis, it should be
identified as the Status Quo, or the baseline or base case. The analysis should concentrate
on the differences in costs and benefits expected to result from the implementation of the
other proposed alternatives versus the baseline. This is proper provided the base case is a
feasible alternative; that is, capable of achieving the stated objectives.
A6.7.2.3. If key variables (e.g., projected workload, legislation) in the base case are
changing, or are expected to change in the near future, does the base case adequately
address the evolving environment? One possible way the analysis can consider the changes
is for it to include a “revised” or “modified” base case, or both a status quo without the
changes and a base case with the changes.
A6.7.3. Is the implementation of each alternative described? It should be clear to the reviewer
what will have to be done to implement each alternative if it were to be selected. Ensure, at a
minimum, that aspects of the alternative that differentiate it from other alternatives in ways
that influence costs and benefits are adequately described.
A6.7.3.1. The reviewer should not be confused over why certain costs or benefits are
included in some alternatives, but not others.
A6.7.3.2. For example, when a Supply Warehouse comparative analysis includes costs for
new material handling equipment in Alternative 2, but not any of the other alternatives,
the description of Alternative 2 should explain the reason, such as this equipment is
required only if the warehouse function were to relocate to a different facility, due to the
different configuration of that facility.
AFMAN65-506 6 SEPTEMBER 2019 89
A6.7.4. Are combinations of systems or projects considered among the alternatives? Given
two or more viable alternatives, would an alternative based on a mixture of two or more
alternatives that combine the best features of each be reasonable? For example, in a
management information system analysis, one alternative might be a manual system and
another might be an automated system. If feasible, a third might be a combination of a manual
and an automated system.
A6.7.5. Are all significant interfaces with existing systems or projects adequately considered
in developing and describing the alternatives? Proper treatment of alternatives requires careful
examination of how the proposed alternatives affect and are affected by related systems or
projects. The need for this examination is crucial in areas such as transportation and
management information systems.
A6.8. Cost Analysis: This section of the comparative analysis describes the cost estimating
methodologies used in the analysis and presents the costs and revenues, as applicable, for each
alternative. What to look for:
A6.8.1. Are all the costs and revenues labeled with their type of dollars, as well as with their
associated FY (e.g., FY18 then-year dollars, FY12 constant dollars)? Check that all totals or
other calculations are completed with the same type of dollars.
A6.8.2. Are cost models identified? A cost model implements the methodology used to
construct the cost estimate. These models may be complex and computer assisted or may
consist of a few relatively simple equations readily computed by hand. The study should
identify and describe all cost models used so the reviewer or decision maker can determine the
validity of the model used and how the cost estimates were derived. If the documentation does
not permit the reviewer to do this, then more information is required.
A6.8.3. Are the cost estimating relationships valid? Does the cost estimating methodology
make sense?
A6.8.3.1. Cost estimating relationships may be unsophisticated cost factors, simple
extrapolation of recent experience, or complex equations with many variables. In all cases,
the purpose of a cost estimating relationship is to translate a characteristic or a specification
of a physical resource (e.g., aircraft weight) or conceptual resource (e.g., lines of code) into
a cost.
A6.8.3.2. Cost estimating relationships should be based on current data, or distorted
estimates may result. For example, the purchase price per pound for engines has increased
over the years due to changes in metal alloy technology (advanced alloys are lighter, but
cost more per pound to produce), and the maintenance cost per flying hour for aircraft has
increased significantly over the past years as more sophisticated aircraft have been
introduced into the force structure.
A6.8.4. Are all relevant costs and revenues that are incremental to the decision included in
constructing the cost estimate? Deciding which costs are relevant requires analysis and
judgment. Preparing a universal list of always-relevant costs is not possible. Ideally, the
analysis should indicate why certain costs were considered relevant and why others were
omitted. Are revenue estimates based on realistic assumptions and computed in the same type
dollar as the costs in the same alternative?
90 AFMAN65-506 6 SEPTEMBER 2019
A6.8.5. Is the time phasing of all cash flows realistic?
A6.8.6. Are any cost avoidance items included in the cost analysis? For example,
productivity improvements sometimes lower costs (and result in savings when compared to
other alternatives), but sometimes only result in cost avoidances. If an alternative is estimated
to save 100 hours per year, but no manpower positions will be eliminated, then manpower
costs will not be reduced. In this situation, productivity savings should be captured as cost
avoidances in the Benefits Analysis section, not as savings in the Cost Analysis section.
A6.8.7. Are sunk costs and inherited assets properly treated?
A6.8.7.1. Inherited assets are those resources such as installations, equipment, and trained
personnel inherited from efforts that are being phased out. Sunk costs are costs already
expended or irrevocably committed. The costs pertinent to decision making are those yet
to be incurred. These previously incurred or committed costs should be excluded from
comparative analyses.
A6.8.7.2. Including the costs of inherited assets and other sunk costs can produce distorted
cost estimates and financial metrics with consequent effect on the conclusions. On the
other hand, if inherited assets have alternative uses, any relevant costs and benefits should
be included in the analysis.
A6.8.8. Are construction costs included? The costs for additional installations or facilities are
sometimes overlooked, yet these costs can be significant. Costs of facility rehabilitation should
also be included.
A6.8.9. Are replacement, consumption, and maintenance costs included? Cost estimates for
major equipment items should include not only the acquisition of the operational equipment,
but also costs for the additional items required for initial inventory and operations and
maintenance for the life of the system (e.g., replacement parts, overhauls).
A6.8.10. Are all training costs included? The resource implications of training personnel can
be significant. Initial training costs represent the resources for training personnel necessary for
introduction of the alternative. The availability of fully trained personnel and the number of
personnel requiring complete or transitional training is the initial resource required. Annual
training costs represent the resource implications for maintaining currency/certifications and
training replacements. These replacements are required because of usual attrition.
A6.8.11. Are all directly related support costs incremental to the decision included in the cost
estimate? Cost estimates of systems or organizations should include the marginal cost of those
other units or elements required in direct support.
A6.8.12. Are investment costs and recurring costs properly categorized?
A6.8.13. Are the cost data accurate?
A6.8.13.1. Cost data can be from many different sources and the reviewer cannot check
all cost data for accuracy. However, the reviewer should consider whether the sources of
data are authoritative and spot check for accuracy. Cost data furnished by manufacturers
should be viewed critically. These cost data may be understated, particularly for new or
advanced projects. Advanced system costs stated as an exact figure rather than presented
as a range with estimated lower and upper values are particularly suspect.
AFMAN65-506 6 SEPTEMBER 2019 91
A6.8.13.2. Great accuracy in cost estimates is often not feasible. In fact, in dealing with
costs of future acquisition, having a range of possible costs (i.e., upper and lower values)
is usually more realistic than a single point cost estimate that implies no uncertainty. The
analysis should use the most likely cost in the estimate, but vary costs with uncertainty in
a sensitivity analysis.
A6.8.14. Are price escalation and inflation appropriately addressed and properly applied?
AFMAN 65-502 provides information on how to appropriately make these adjustments.
A6.8.15. Are costs presented in terms of present value? As explained in paragraph 4.5.6.4.1.,
were midyear discount factors used (vice End-of-Year factors)? The costs of proposed
alternatives will differ both in total dollars and in the percentage distribution of the total over
the years included in the period of analysis. The present value, or discounting method, is the
means by which dollars in any year of the analysis can be converted to dollars of the present
so they can be compared. Using midyear discount factors produces consistency in identifying
the resource implications of proposed investments. Any use of End-of-Year or other discount
factors should be explained in the Assumptions section. The report may also present costs in
other types of dollars, but present value dollars is required.
A6.8.15.1. If the analyst prepared the comparative analysis using an Air Force approved
comparative analysis software application, then it is safe to assume all the discounting
calculations were done correctly. If not, spot-check the calculations, including calculations
of the discount factors from the discount rates (or double-check ALL calculations if there
is reason to believe there may be calculation errors).
A6.8.15.2. If part of the analysis report identifies funding required by FY in order to
facilitate budget preparation, those dollars should be presented in then-year dollars for that
section of the analysis and analysis report.
A6.8.16. Are cost aspects of all alternatives treated equally? Inconsistency in handling the
costs of competing alternatives prevents an objective evaluation and can lead to incorrect
conclusions. Realize, though, that using the same cost estimating technique for calculating a
particular cost element for all alternatives is not always possible. The issue is whether the final
dollar estimate accurately reflects the actual resource requirements for the alternative and that
the differences in estimating techniques do not distort the cost results. Are wash/common costs
included in the cost estimate of any of the alternatives? If so, they should be included in the
cost estimate for all alternatives.
A6.8.17. If costs are incurred in foreign currency, have they been converted at the known or
estimated exchange rate of the base year of the analysis, NOT the Foreign Currency Fluctuation
Account budget rate? Verify that an explanation of the exchange rate being used is provided,
as well as its source. The assumptions section is a typical location for this explanation.
A6.9. Benefits Analysis: This section of the comparative analysis identifies, measures, and
evaluates the non-monetary benefits of the proposed alternatives. What to look for:
A6.9.1. Are any monetary (i.e., budget) benefits included in the Benefits Analysis?
A6.9.2. Only non-monetary (non-budget) benefits should be included in this section.
Therefore, cost avoidance items can be included, but no savings. Budgetary effects should be
included in the Cost Analysis.
92 AFMAN65-506 6 SEPTEMBER 2019
A6.9.2.1. Examine any items identified as cost avoidance to ensure they are not actually
savings.
A6.9.3. Are the benefits clearly defined and mutually exclusive? Ensure there is no overlap
in benefits (i.e., double counting of benefits). For example, if upgrading an aircraft’s
propulsion system, two possible benefits that sound different, but likely overlap would be
“Range of Aircraft” and “Air Refueling Tanker Demand.”
A6.9.4. Are the benefits all equal in importance? If not, was a weighting system used to adjust
the level of impact each benefit has on the analysis? If so, does the weighting scheme seem
logical and consistent?
A6.9.5. Are the benefit measuring techniques identified and explained? The study should
clearly identify the standards or measures used for evaluating the quantity of benefits provided
by the alternatives under study. The alternatives cannot be properly evaluated, particularly
when their costs are similar, without proper evaluation of the benefits received.
A6.9.5.1. Are some aspects of benefits received not measurable? The treatment of
immeasurable benefits in the total measurement of benefit should be treated thoughtfully.
A6.9.5.2. Measures of benefit obtained by quantifying study aspects such as morale or
leadership can be misleading. At times, the only practical solution may be a qualitative
discussion of these factors.
A6.9.6. Is the evaluation of benefits based on straight extrapolation? Occasionally a study may
evaluate benefits by straight (linear) extrapolation from the measurement of benefits of a small
unit. For example, a hypothetical study may show that Airmen are twice as happy when the
dining hall serves three entrees rather than one. An extrapolation stating that 21 entrees will
make Airmen 10 times happier (i.e., two additional entrees increase happiness by X, so 20
additional entrees will increase happiness by 10X) may not be justified without supporting
evidence. The potential error in straight line extrapolation is that it disregards the concept of
diminishing marginal utility (i.e., diminishing returns).
A6.9.7. Is the impact of other operations ignored? In measuring the benefits of a system or
organization, consider the effects on other operations. For example, peak use of power, or
vehicles, or people may have detrimental effects on related projects or activities. The "ripple
effect" should be considered.
A6.9.8. Do the benefits of future systems take into account the timing of benefits? The benefits
of a proposed future system often depend on when it will be available for operational use and
the total operational life span (economic life) of the system. In examining the effect of the time
dimension on benefits, pay particular attention to the time between the present and the initial
operational availability of the complete system.
A6.9.9. Is there a reason to believe there is significant execution or schedule risk associated
with the alternatives? If so, risk can be handled either in the Benefits Analysis or the
Uncertainty Analysis sections of the comparative analysis. If it is not in the Benefits Analysis,
make sure an independent risk assessment is included in the Uncertainty Analysis.
A6.9.9.1. The more easily risk can be quantified and measured, the easier it is to handle in
the Benefits Analysis. If the risks are difficult to quantify and measure, it might be more
appropriate to include the risk assessment in the Uncertainty Analysis.

A6.9.9.2. If the amount of risk is not quantified, is a convincing explanation provided on
why the risk was different across the alternatives and what characteristics drove the risk or
distinguished the alternatives?
A6.9.10. Has the analysis included any benefits that were realized in the past? Like sunk
costs, unless benefits will be received in the future as a result of implementing an alternative,
they should not be recognized as benefits.
A6.10. Uncertainty Analysis, including Sensitivity Analysis and Risk: An Uncertainty
Analysis includes a Sensitivity Analysis and may include a Risk Analysis. Sensitivity Analysis
tests the effect that uncertain assumptions have on the results of the alternatives relative to each
other. A Risk Analysis evaluates risk to program execution (cost, schedule, performance) and risk
to the Air Force for each alternative. What to look for:
A6.10.1. Is a Sensitivity Analysis performed on all assumptions whose value is uncertain and
significantly affects analysis results? The study should clearly explain how sensitive analysis
results (costs and benefits) are to changes in assumption values.
A6.10.1.1. Verify that cost elements that constitute a high percentage of total life cycle
costs were considered for a Sensitivity Analysis. Similarly, verify that benefits constituting
a large relative weight were considered for a Sensitivity Analysis.
A6.10.1.2. If the present values of the two lowest-cost alternatives are very close, a
Sensitivity Analysis should be done on the most uncertain assumption(s) of the alternatives,
and if it shows a change in the cost ranking of alternatives, this should be pointed out in
the Summary and Comparison of Alternatives section.
A6.10.2. Are the processes followed in conducting all sensitivity analyses explained?
Additionally, are the results of each sensitivity analysis explained? Reader of the comparative
analysis should not have to rely solely on graphs and charts. An explanation of the graphs and
charts highlighting the important findings should be included.
A6.10.3. For each sensitivity analysis performed, did the sensitivity analysis consider the
effects of varying variable values across the entire range of reasonable values for the period of
analysis? For example, if the period of analysis is two years and current interest rates are 5
percent, a reasonable range for a sensitivity analysis might be 3-7 percent. However, if the
period of analysis is 20 years, a reasonable range might be 1-10 percent.
A6.10.3.1. If sensitivity analyses show a change in the cost ranking of alternatives, is this
finding pointed out in the Summary and Comparison of Alternatives section?
A6.10.3.2. Are the crossover points for each assumption identified?
A6.10.4. The period of analysis is often not considered to be a subject for sensitivity analysis,
but if one or more alternatives have occasional “balloon” costs (e.g., overhaul of heavy
equipment, replacement of air conditioners, water heaters, washers/dryers, and other durable
goods), it probably should be. For example, would 10 years of operations as opposed to 5
make a significant difference in the relative costs of the alternatives?
94 AFMAN65-506 6 SEPTEMBER 2019
A6.10.5. For qualitative assumptions, were sensitivity analyses considered? A useful
technique is to make other plausible major assumptions (e.g., the use of a Fixed Price contract
versus a Cost Plus contract). If these invalidate the study’s results, then the analysis should
discuss the assumption values that drive the results and try to assess the likelihood of the
different values.
A6.10.6. The number of sensitivity analyses required and feasible is a matter of judgment.
There are limits to the time and manpower available for a given study. At the minimum,
though, a sensitivity analysis should be performed on assumptions with uncertainty and a large
effect on analysis results. Variables comprising a large percentage of costs should also be
considered for sensitivity analysis. The reviewer should have a confident understanding of the
circumstances under which analysis results would change.
A6.10.7. Does the level of risk associated with any alternative have a reasonable likelihood of
being a key consideration for the decision-maker? Or, is a risk analysis required by the type
of analysis or the decision-maker? If so, ensure a risk analysis is performed. If not, a risk
assessment is not required.
A6.10.8. If a risk analysis is included, does it assess the following issues (if appropriate):
A6.10.8.1. Risk that the benefits expected from an alternative may not be achieved. If
there is uncertainty associated with the assumptions in the benefits analysis, a risk analysis
can examine the probability and impact of not achieving the benefit.
A6.10.8.2. The degree of execution risk (i.e., cost, schedule, or performance) associated
with the alternatives.
A6.10.9. Ensure the cost of any risk mitigation measures assumed when assessing the risk of
an alternative are included in the cost analysis.
A6.10.10. Make sure the risks are adequately explained and are included in the Summary and
Comparison of Alternatives section.
A6.10.11. If risk is not quantified, make sure a convincing explanation is provided on why the
risk is different across the alternatives and what characteristics drive the risk or distinguished
the alternatives.
A6.10.12. Ensure risk elements rated as zero risk are included in the overall assessment of risk
unless they are common among all alternatives. Leaving those elements out biases the risk
assessment.
A6.11. Summary and Comparison of Alternatives: This is where the analyst summarizes the
results of the Cost Analysis, Benefit Analysis, and Uncertainty Analysis for each alternative,
compares the strengths and weaknesses of each alternative with respect to the other alternatives,
and explains the implications of the results. What to look for:
A6.11.1. Are the present value of costs and revenues summarized, compared, and discussed
across alternatives? (Ensure cost avoidance is not included in the discussion of costs).
A6.11.2. Are the benefits, both quantitative and qualitative, compared across alternatives?
A6.11.3. Are the results of the Uncertainty Analysis summarized and the assumptions with
crossover points identified?
AFMAN65-506 6 SEPTEMBER 2019 95
A6.11.4. Are summary tables accompanied by a narrative explanation of the summarized cost
and benefit data and uncertainty assessment included?
A6.11.5. Are analyses expressed in qualitative terms summarized?
A6.11.6. Are the criteria for comparison identified? The criteria (i.e., or characteristics of
cost, schedule, and performance) are the bases for the conclusions. The criteria should be
stated specifically and clearly.
A6.11.7. Are the criteria too general? Very general criteria should be suspect. For example,
a study may state a criterion as being "the system with maximum military worth" or the "best
system." These generalizations can be interpreted differently by different people and,
therefore, are not meaningful. Good criteria leave less room for individual interpretation (e.g.,
“the minimum cost of maintaining a specified level of transport capability over a specified
time span.").
A6.11.8. Is the interpretation of results (conclusions) logically derived from the material in
the study?
A6.11.8.1. Do the conclusions show bias? Studies sometimes unwittingly show bias
because of parochial or institutional interests. One test for bias is to judge whether the
same conclusions would be reached by another study agency based on the material in the
study.
A6.11.8.2. Are the conclusions based on outside considerations? If so, document those
considerations in the analysis.
A6.11.8.2.1. Occasionally, conclusions must be drawn in the face of great uncertainty.
A study may find several alternatives exhibiting similar costs and benefits, but the
results are very sensitive to the values assigned to the inputs. In this situation, some
studies arrive at conclusions based on considerations other than those studied. In other
words, the study agency is stating, after the analysis was performed, that applying the
criteria did not lead to a preference, but rather to indifference among the alternatives.
In that case, the issue was decided based on other unstudied criteria. In situations of
this kind, those criteria should be stated, and sensitivity to the unstudied criteria must
be examined.
A6.11.8.2.2. Some studies draw conclusions based on previous studies and materials
that are not fully documented within the study (mention in a bibliography is not
enough). If input from another study is essential, it should be documented and
explained. This requires at least a statement of the validity, scope of application, and
uncertainty related to the particular input.
A6.11.9. Have all the significant consequences been considered in arriving at the conclusions
and interpretations?
A6.11.9.1. Sometimes a study fails to consider all the pertinent consequences in
developing the conclusions of the study or arriving at the decisions to be made. These
consequences are often referred to as "spillovers." For example, if a study recommended
adoption of an engine requiring a new type of fuel, the supply system to include supply,
storage, and transportation operations would be affected.
96 AFMAN65-506 6 SEPTEMBER 2019
A6.11.9.2. Spillover effects are not always negative. For example, adopting dehydrated
rations to achieve greater shelf life may also reduce construction and transportation costs
because of the smaller unit volume and weight of dehydrated food.
A6.11.10. Are the interpretations and conclusions in this section consistent with the
interpretations in the Executive Summary? Sometimes, changes made in one of these do not
catch up to the other sections before the documentation is finalized.
A6.11.11. Are the conclusions intuitively satisfying? When the conclusions of the study are
not intuitively satisfying, one should try to isolate the cause. If the study fails to show by data,
models, and other means that the intuition is wrong, further examination is required to
determine if some subtle considerations have been neglected because of over simplification or
other reasons.
A6.11.12. Are the criteria consistent with higher echelon objectives? No matter what the
concern of a study, the subject falls into a larger framework. Are the criteria used in the study
consistent with higher-level objectives? This requires management judgment and the necessity
to examine the larger context of the problem. If the study criteria are not consistent with
objectives at the higher level, then the analysis may be addressing the wrong problem (sub-
optimization).
A6.11.13. If a recommendation is included in the analysis, does the recommendation logically
follow from the conclusions? Is the rationale used to determine the recommendation included?
Consider the feasibility of the recommended alternative in light of political, cultural, policy,
and other considerations not included in the analysis.
A6.12. Documentation and Data Evaluation: This is everything that serves as the basis for
the analysis. Each comparative analysis should be a stand-alone document, so it should include
copies of source data and all calculations used to turn source data into comparative analysis inputs.
A reviewer should be able to understand the comparative analysis without having to look at
anything else. They should be able to replicate the comparative analysis using the source data and
documentation. If the reviewer does not feel the documentation provides enough information to
do so, the documentation may be insufficient. What to look for:
A6.12.1. Is the analysis adequately documented? One characteristic of good documentation
is that it provides enough information about the data sources and methodology used so a reader
not familiar with the study could arrive at essentially the same result. Without documentation,
an analysis appeals for acceptance solely on faith in the authority of the issuing agency.
A6.12.2. Are all data sources provided? Are the data sources authoritative?
A6.12.3. Are the facts correct? It is usually not possible to verify all the facts from a variety
of sources used in the study. However, facts upon which conclusions are based should be
specifically evaluated.
AFMAN65-506 6 SEPTEMBER 2019 97
A6.12.4. Are the facts stated with proper qualifications? In addition to checking the validity
of the facts, completeness should also be evaluated. Some material may be correct in isolation,
but may take on a different meaning when other facts are added. For example, a bulldozer may
generally be able to move "x" cubic yards of earth per day. However, this rate may not be valid
for earth removal in rocky or frozen terrain. Likewise, a builder might be able to construct
buildings at a certain pace, but if work cannot be performed in the rain, then the rate of
construction may not be valid if the project is scheduled for rainy season.
A6.12.5. Are the performance characteristics valid?
A6.12.5.1. Performance characteristics are often the key element in determining the
benefits of a system or piece of equipment.
A6.12.5.2. In evaluating the validity of performance characteristics, the source of the data
should be examined.
A6.12.5.2.1. Performance characteristics based on manufacturer’s claims are often
optimistic.
A6.12.5.2.2. Performance characteristics derived from tests at research installations
also require examination. Test performance characteristics are usually derived under
controlled conditions. Performance characteristics derived from field tests should be
examined. Such tests can, at times, produce misleading results due to artificialities
caused by abnormally stringent operating and safety regulations and choice of test
areas.
A6.12.6. Are the data from supporting simulation models valid? Does the analysis use the
results from simulation models in an appropriate manner?
A6.12.6.1. In determining the validity of simulation results, the reviewer should judge how
well the model portrays the essential relationships. The review should also evaluate the
validity of the judgments and assumptions used in conducting the analysis. Major
judgments and assumptions used in the model should be fully identified.
A6.12.6.2. Studies sometimes use the results of simulation models as facts. In evaluating
whether the analysis uses simulation results appropriately, the reviewer should consider
the nature of simulation. Basically, a simulation involves an abstraction from the real
world. Models are structured according to mechanistic rules or judgments or both, and
these are made by people. Additionally, many assumptions are made when constructing
the model. Therefore, simulation results should not be treated as fact. However, they can
be used to provide insight into problem behavior, and sensitivity analysis can be used on
the simulation model assumptions to determine the volatility of the model’s results, or on
the model’s output if it is fairly stable and predictable.
A6.12.7. Are any of the data derived from questionnaires? The data obtained from
questionnaires should be examined to determine the validity of the questions, adequacy of the
number of people surveyed, and the relevant qualifications of the people surveyed.
A6.12.8. This is the end of the reviewer’s guide. If reviewer need more assistance in
reviewing a comparative analysis, there is also a Comparative Analysis Preparer’s Guide in

Table A7.1. Midyear discount factor.
A7.2. End-of-year discount factor.
Table A7.2. End-of-year discount factor.
A7.3. Present Value (PV): Present Value is the value of a future amount or series of future
amounts, discounted to reflect the time value of money. The future amounts are discounted to a
date chosen by the analyst (e.g., first year of investment). Present value comparisons are used in
economics to meaningfully compare different cash flows. Present Value is the primary cost
measurement for decision-making and will be included in all formalized cost comparisons.
AFMAN65-506 6 SEPTEMBER 2019 99
Table A7.3. Present Value (PV).
A7.4. Uniform Annual Cost (UAC): Uniform Annual Cost is a method to compare alternatives
with unequal lives, UAC is calculated by dividing the present value of the costs of an alternative
by the sum of the discount factors for the periods covering the life of each alternative in which
costs were incurred. The following is a notional example showing the Uniform Annual Cost
calculations for two alternative methods for meeting an objective. The first alternative has an
economic life of 5 years and the second alternative has an economic life of 10 years. The example
uses a 2.7% midyear discount rate:
Figure A7.1. Uniform Annual Cost Calculation Example.
A7.4.1. UAC Calculation. This table above shows that Alternative A has a lower total cost
than Alternative B, but their economic lives of the alternatives are different. The benefit of
Alternative B is being received for 10 years and only the benefit of Alternative A is being
received for 5 years. When the difference in economic lives of the alternatives are normalized
using the UAC Approach, Alternative B has a lower Uniform Annual Cost.
100 AFMAN65-506 6 SEPTEMBER 2019
Table A7.4. UAC Calculation.
A7.4.2. Uniform Annual Cost is used as an alternative to the Terminal Value Method of
reporting costs for the alternatives. The Uniform Annual Cost measure has the benefit of not
requiring the estimate of a terminal value. Senior leaders will differ as to which method they
prefer.
A7.5. Savings/Investment Ratio (SIR): The SIR equals the present value of the savings
generated from an investment divided by the present value of the implementing investment
amount. The SIR should include all savings across the program life.
Table A7.5. Savings/Investment Ratio (SIR).
A7.6. Return on Investment (ROI): The present value of the total return generated by an
investment (minus the implementing investment amount) divided by the present value of the
implementing investment amount.
Table A7.6. Return on Investment (ROI).
A7.6.1. Return on Investment is required in Clinger-Cohen Act Economic Analyses.
A7.6.2. The Return on Investment is very similar to the Savings to Investment ratio. They are
related by the following formula.
Table A7.7. Savings to Investment ratio.
A7.6.3. Return on Investment is useful for projects that are expected to achieve efficiencies
that would realize savings or a profit. Return on Investment allows for a comparison of
financial return as a percent of the implementing investment. A drawback of Return on
Investment is that it does not provide the magnitude of the financial benefit/cost in absolute
terms (present value calculations provide that information). Many government projects are
selected for the non-monetary benefits they yield. As a result, return on investment may be
zero or negative for many government projects.
AFMAN65-506 6 SEPTEMBER 2019 101
A7.7. Cost/Benefit Ratio (CBR): The present value cost of an alternative divided by the benefit
measure of that alternative. The result will be the average cost per unit of benefit. This metric is
applicable with benefits measured quantitatively (e.g., direct quantitative measure or weighted
benefit score)
A7.7.1. This technique should be used with caution. Decisions generally should not be made
on average costs and benefits, but instead should be based on marginal costs and benefits. As
an example, assume the benefit being measured is hangar size as measured in square meters,
assuming all square meters of area produce the same marginal benefit. Nominal life cycle
costs and the benefits are provided in the Figure A7.2
Figure A7.2. Notional Example Cost Benefit Ratio.
A7.7.2. The cost per benefit ratio in Figure A7.2 implies that the status quo is a better choice
than the Add/Alter alternative because the average cost per square meter is lower. However,
the decision should not be based on which alternative has the lower average cost per square
meter. Instead, the decision should be based on whether the decision-maker believes the
additional 1,000 square meters is worth $4.5M. That is the marginal cost paid for the marginal
benefit received. Even though the cost per benefit is higher for the additional 1,000 square
meters, that may still be an acceptable price for the decision-maker.
A7.7.3. An additional concern with cost benefit ratios is that with some types of analyses, the
decision-maker does not directly incur the cost for the benefit received. For example, funding
for major MILCON projects does not come out of a local organization’s budget. The fact that
the cost is not directly incurred at the local level, may impact how benefits are valued relative
to cost.
A7.8. Payback Year:
A7.8.1. To calculate the Payback Year, add the expected savings for each period (i.e., the
numbers in the Annual Totals column) until the cumulative total equals or exceeds the
investment total. That will be the year in which payback is achieved. In the example in Figure
A7.3 below, investments are reflected as negative cash flows in the Annual Totals column. All
of the cash flows are the incremental changes that result from the decision to invest. By the
end of the investment year (year 0) there are cash outflows of $100,000. By the end of year 1,
there is a mix of cash outflows and savings that net to $50,000. By the end of year 2 and for
subsequent years, the incremental cash flow has turned positive in that the savings now exceed
the incremental cost for that year. Looking at the Cumulative Totals column, the cumulative
cash flow switches from negative to positive sometime in year 5, so the Payback Period is
between 4 and 5 years. To calculate the Payback Period, the analyst needs to have an idea of
the schedule of cash inflows in the Payback Year. In this case, cash inflows will be $53,000
and there will be $50,000 remaining until payback is reached. It is common to assume that the
cash inflows occur evenly throughout the year. As a result, the portion of year before payback
102 AFMAN65-506 6 SEPTEMBER 2019
is reached is:


. As a result, it takes 4.94 years, or about 4 years and 11 months
to reach payback.
A7.8.2. By convention, payback year analysis ordinarily uses un-discounted dollars.
Figure A7.3. Payback Year Example (TY19$).
A7.8.3. Payback is useful for projects that are expected to achieve efficiencies. Payback tends
to be biased toward projects with earlier savings. This could be good given that savings later
in the life of a project are commonly less certain. The drawback is for those cases where
savings expected later in a project are anticipated to be much larger than the other alternatives.

PRELIMINARY COMPARATIVE ANALYSIS
A9.1. Preliminary comparative analyses are internal planning tools. A preliminary
comparative analysis is a first, less detailed effort of performing a comparative analysis. Typically,
the Air Force performs preliminary comparative analyses early in project consideration: (1) when
it is more practical to do an abbreviated analysis and (2) to provide for a better understanding of
which alternatives of a specific project merit further development/consideration. A preliminary
comparative analysis could also be used when resources are limited and there are many potential
projects that would benefit from an analytical approach. There are some situations where a
preliminary analysis is required. See AFI 65-501.
A9.1.1. The findings of a preliminary comparative analysis do not preclude a different set of
findings or recommendation in a full comparative analysis.
A9.1.2. When a preliminary analysis has been done, care should be taken to ensure the
decision-maker is not anchored to those results when subsequent information in the full
comparative analysis leads to different results.
A9.2. In no case may a preliminary comparative analysis be substituted for: A full
comparative analysis when a full comparative analysis is required by AFI 65-501.
A9.3. The format below provides: An idea of the contents appropriate for a preliminary
comparative analysis, which is generally a document of no more than a few pages.
A9.3.1. Background. Provide a brief, relevant and clear context surrounding the project.
A9.3.2. Objective. State the generic need in an unbiased, non-limiting manner, quantified to
the extent possible, e.g., provide adequate housing for 300 unaccompanied enlisted personnel.
If "adequate" can be translated into square footage or other parameters, this quantification
should be done.
A9.3.3. Facts/Assumptions/Ground Rules. Identify only the most significant limitations,
constraints, assumptions, legal or regulatory considerations, e.g., all dormitories are currently
averaging 95 percent occupancy; no present base organizations are planned to be inactivated
or relocated.
A9.3.4. Alternatives. Identify, as a minimum, all alternatives that sound reasonable.
Categorize the alternatives into two groups: feasible alternatives to be analyzed (e.g., status
quo, renovation, new construction, basic allowance for housing (BAH)), or infeasible
alternatives to be eliminated (e.g., leasing). Analyze all alternatives that are both reasonable
and feasible. Include reasons for eliminating infeasible alternatives.
110 AFMAN65-506 6 SEPTEMBER 2019
A9.3.5. Costs. Identify the major categories of costs and include preliminary estimates by
major category. "Wash" or common costs may be excluded. Ignore minor categories of cost
or incidental costs. Summarize the differences in costs among alternatives as a rough order of
magnitude. Discounting would only be necessary in a preliminary comparative analysis if cash
flows vary significantly in timing. Work to develop cost estimates with the appropriate local
functional expert (e.g., facility maintenance and new facility construction costs from civil
engineering, number of dorm occupants by pay grade from base billeting office).
Documentation of costs should be at an appropriate level to track both the source of the data
and the methodology behind the estimate. Calculations should be checked for accuracy.
A9.3.6. Benefits. Identify the more important benefits associated with each of the
alternatives being analyzed (e.g., renovation corrects all deficiencies, or opting for off-base
housing results in demolishing old poor quality dorms.
A9.3.7. Uncertainty (Sensitivity/Risk) Assessment. Identify the key variables which, if
varied within a reasonable range of analysis, could possibly change the results of the analysis.
Also, identify any significant risks to project execution or benefit realization for each
alternative.
A9.3.8. Summary and Comparison of Alternatives. Briefly summarize the cost, benefit
and uncertainty analysis and interpret the results. Emphasize that the conclusions are based on
preliminary analysis only and could possibly change based on results of a complete, formal
comparative analysis.

Attachment 11
REAL PROPERTY CONSTRUCTION AND REPAIR ECONOMIC ANALYSES
A11.1. Introduction. This Attachment provides guidance on the preparation of construction and
repair comparative analyses required as part of the project justification process for Facility
Improvement, Replacement, and New Construction projects. Based on the guidance governing
the requirement analyses, a comparative analysis for real property construction and repair is called
an economic analysis. A thorough and well documented economic analysis is a critical factor in
project approval and subsequent Congressional appropriation. The purpose of this manual is to
assist in conducting and documenting the results of applying the economic analysis approach to
real property decisions. In this area, the analyses that result are called economic analyses.
A11.1.1. Types of Facilities Covered. The information contained in this section is relevant
to construction and repair projects.
A11.1.2. Relevant projects include, but not limited to: administrative facilities, transient
quarters, dormitories, maintenance facilities, warehouses, child care facilities, Military Family
Housing and mission support facilities.
A11.2. Initiating and Updating an Economic Analysis
A11.2.1. An economic analysis is initiated as early as practical during the project planning
process. An early start assures the analysis is in place for decision making and allows sufficient
time to collect all the necessary data to conduct a more accurate life cycle cost analysis and a
more informed benefit and uncertainty analysis in order to provide better information and lay
the foundation for superior program support documentation.
A11.2.2. Do a preliminary economic analysis after an Installation Facilities Board has
established a requirement for a project, but before the Installation Facilities Board has chosen
an alternative. Develop the preliminary analysis as the civil engineering staff develops the
Department of Defense Form 1391.
A11.2.3. Complete a full economic analysis or a waiver to an economic analysis for each
facility project likely to be funded in the budget year. Complete the analysis prior to the
documentation deadline contained within the respective facility project business rules (e.g.,
MILCON; Unspecified Minor MILCON; Facilities Sustainment, Restoration, and
Modernization). The preliminary economic analysis is often the basis for this full economic
analysis unless conditions surrounding the project have changed substantially.
A11.2.3.1. For MILCON projects, a completed economic analysis or approved waiver
must be evident in each project’s development and analysis before the Air Force Corporate
Structure decides to include the project in the Air Force’s Program Objective Memorandum
submission. (T-1).
A11.2.3.2. For Unspecified Minor MILCON, Unspecified Minor Construction, or repair
projects, an approved economic analysis or waiver must be part of each project’s
development and analysis at cost thresholds in AFI 65-501, and must be included as
attachments in higher headquarters approval request packages. (T-1).
AFMAN65-506 6 SEPTEMBER 2019 113
A11.2.4. An economic analysis is updated when significant developments occur that would
invalidate or alter its conclusions. The following situations require an update to the economic
analysis if there is decision space remaining to impact execution of the project:
A11.2.4.1. When there is a change in project scope.
A11.2.4.2. If there are major changes in the initial study assumptions.
A11.2.4.3. When new alternatives are identified that appear to satisfy the stated
requirement.
A11.2.4.4. If changes in costs or benefits would be likely to change a decision made using
the analysis.
A11.3. Analysis Coordination. According to AFI 65-501, the primary responsibility for
performing the economic analysis lies with the FM staff at the affected organizational level.
Collateral responsibility lies with the Civil Engineering staff and the project user. Completing the
economic analysis requires close coordination between Civil Engineering, FM, and the end user
of the facility. Figure A11.1 presents the responsibility matrix. Some of the tasks have multiple
OPRs and Offices of Collateral Responsibility (OCRs). In these cases, the asterisks indicate the
division of responsibilities within the task. The responsibilities in the matrix are for both economic
analyses and waivers to the economic analysis requirement. See Attachment 3 of this manual for
the certification process for construction and repair economic analyses and for the approval process
for economic analysis waivers.

A11.4. Analysis Foundational Elements
A11.4.1. Defining the Project, Formulating Assumptions, and Identifying
Alternatives. A clear, concise statement of the project objective is necessary in order to
identify potential alternatives for the project. This section will assist the analyst in accurately
identifying the problem, defining the project objective, formulating assumptions, and
identifying alternatives to meet the need.
A11.4.2. Collecting and Reviewing Background Information. The analyst collects and
reviews all written documentation available that could affect any project alternatives. This
review will include: the most current Department of Defense Form 1391, the construction cost
estimate for the proposed project, previous economic analyses, the Base Comprehensive Plan,
and the Planning Charrette Report. Next, interviews are conducted with personnel involved in
the project planning process and with the current facility users. The current facility users are a
good source for identifying deficiencies in the existing facility. All information is collected in
writing, including the source of the data, and the name, organization, title, and phone number
of each point of contact. The signed source documents are presented in Appendix B of the
economic analysis.
Figure A11.2. Sample Questions for Interviews and Background Data Collection.
AFMAN65-506 6 SEPTEMBER 2019 115
A11.4.2.1. The issues raised in the sample questions have to be identified in order to
determine scope of the proposed project. For example, a facility that is on or under
consideration for addition to the National Register of Historic Places may not be eligible
for demolition and could generate unique architectural/engineering compliance
requirements for renovation. As another example, asbestos, radon, or lead-based paint in
the existing facility can lead to costly abatement procedures which may impact the project
schedule. These costs may be incurred if the facility is renovated or demolished, depending
on the scope and type of remediation required.
A11.4.2.2. When reviewing the current facility situation, it is important to consider the
user. Does the existing facility meet the needs of the user? Are the current working
conditions affecting morale? Is an organization disjointed and spread over several
facilities? Would the organization work more efficiently if it were consolidated into one
facility? Could labor time be saved or duplicate functions be eliminated as a result of a
consolidation? It is important to address these and other types of user concerns when trying
to define the requirement.
A11.4.2.3. The following are possible facility deficiencies and other concerns that may
need to be addressed for the proposed construction or repair project.
Figure A11.3. Possible Facility Deficiencies.
A11.4.3. Defining the Project Objective. From the information collected, a clear, concise
statement of the project objective should be developed.
A11.4.3.1. When writing the project objective, it is important that the statement not be
biased toward any alternative. Also, the project objective should be quantified to the extent
possible.
A11.4.3.2. Once the project objective is clearly defined, the analysis team will identify
alternatives that satisfy the requirement. Figure A11.4 presents examples of project
objectives for several facility types. (T-2).
116 AFMAN65-506 6 SEPTEMBER 2019
Figure A11.4. Sample Analysis Objectives for Selected Construction and Repair Projects.
A11.4.4. Formulating Assumptions. Economic analyses are based on facts and data
pertaining to the project in question. However, an economic analysis deals with costs and
benefits occurring in the future. Since the future is unpredictable, assumptions and sensitivity
analyses are prepared to account for uncertainties. To avoid invalidation or bias of the analysis,
assumptions based on realistic assessments or anticipated conditions should be made by
qualified individuals. There are several common assumptions made when preparing an
economic analysis for a construction or repair project:
A11.4.4.1. Economic Life of the Project. The economic life for construction and repair
projects is different for each facility type. Additionally, the economic life of a renovated
facility is normally less than a newly constructed facility.
A11.4.4.1.1. Residual Value. Residual Value is the remaining (depreciated) value of
the facility at a point in time. Residual value is normally calculated using straight-line
depreciation of the start value over the project's economic life. State which method is
used to determine the assumed residual value.
A11.4.4.1.2. Inflation and Escalation. The source and date of all inflation and
escalation indices used must be documented in the assumption section. (T-2). Inflation
measures a sustained rise in the general price level. When historical data is used to
estimate future costs, the historical costs must be escalated to the year in which funds
would be appropriated for the project using a specific price index. (T-2). When
converting those costs to a constant year dollar (or base year dollar), use the inflation
index published by SAF/FMC. (T-1). Consult the Resource Management Cost Division
(formerly FM Center of Expertise) or SAF/FMCE for assistance on escalation indices
and inflation indices.
AFMAN65-506 6 SEPTEMBER 2019 117
A11.4.4.1.3. Discount Rate. The discount rate is used to account for the time value of
money when comparing the cost and benefits of alternatives over several years and is
documented as an assumption. Economic analyses performed to support Air Force
construction and repair programs should be discounted at the interest rate published in
the most recent President's Budget. The President’s Budget is published in January or
February of each year and includes both the constant and current-dollar discount rates
to be used in economic analyses. The annual discount rates are posted on the
SAF/FMCE SharePoint
®
page, to which a link is provided on the SAF/FMCE page of
the Air Force Portal. These discount rates reflect the latest values contained in the
OMB Circular A-94 Appendix C.
A11.4.4.1.4. Additional assumptions will likely be required when project data is
unavailable, when future costs are uncertain, or when a project involves unique
circumstances.
A11.5. Identifying Alternatives. For potential construction and repair projects, there are
typically six possible alternatives available to meet the objective:
Figure A11.5. Typical Construction and Repair Project Alternatives.
A11.5.1. Typical Alternatives
A11.5.1.1. The first three typical alternatives (Status Quo, Improvement and New
Construction/Replacement) are always reasonable alternatives for real property
construction and repair decisions. As a result, they must be included in all real property
construction analyses and waivers. (T-1). They may be deemed infeasible when
appropriate, but must at least be addressed. The last three typical alternatives (Leasing,
Community Partnerships and Non-Construction Solutions) may or may not be reasonable
alternatives given the project under consideration.
A11.5.1.2. The Status Quo alternative is considered the baseline for the economic analysis.
The Status Quo can be one or a combination of scenarios. Four common examples are:
A11.5.1.2.1. The continued use and operation of existing facilities in their current
condition.
A11.5.1.2.2. The continued payment of Basic Allowance for Housing to personnel
living off base in private residential housing when there is insufficient dormitory space
on base.
A11.5.1.2.3. The continued payment of lodging per diem to personnel on temporary
duty when there are insufficient transient quarters on base.
118 AFMAN65-506 6 SEPTEMBER 2019
A11.5.1.2.4. The continued use of temporary leased space in a privately owned facility
off base.
A11.5.1.3. The Improvement alternative involves renovating an existing facility to
eliminate deficiencies and/or reduce future maintenance and repair costs, altering the
facility to improve its operating efficiency, or constructing an addition to the facility to
increase space. Various levels of improvements can be addressed as alternatives, from
minimal correction of life-safety deficiencies to comprehensive "gut and rebuild" efforts.
The actual work to be performed is explicitly documented in the analysis.
A11.5.1.4. The New Construction or Replacement alternative consists of the construction
of a new facility in order to eliminate an existing shortage or deficiency, to meet a shortage
or deficiency created by a new mission or mission change, or to replace a substandard
facility. If new construction involves replacing an existing facility, then the disposal of the
existing facility is addressed.
A11.5.1.5. A Government Leasing alternative involves direct, long-term leasing by the
Air Force of a suitable, privately owned facility off base. General Services Administration
handles long-term leases for general-purpose facilities. If leasing is used to replace an
existing facility, then the disposal of the existing facility is addressed.
A11.5.1.6. The Community Partnerships alternative can use partnerships with local public
and private sector organizations to provide facilities for the Air Force.
A11.5.1.7. Non-construction alternatives consider that there may be ways of resolving the
need without construction. It is important to remember that improved facilities are just one
way of meeting a need. Other alternatives may include making operations more efficient
so that a new facility is not required. For instance, a shortage of warehouse space may be
compensated for by acquiring new handling and stacking equipment that allows more
efficient use of vertical space (i.e., cubed footage) or instituting just-in-time parts provision
procedures. Another solution may involve consolidating related functions to make better
use of existing or new space. These innovative approaches to meeting space requirements
can result in significant cost savings, and may offer the added benefit of improving
operational efficiency and/or productivity. It is important that the user take an active
role in alternative development so that these non-facility solutions can be properly
represented.
A11.5.2. In the case of a transient or dormitory quarters requirement, a direct compensation
alternative may also need to be considered.
A11.5.2.1. Direct compensation is an alternative when:
A11.5.2.1.1. There is suitable housing off base for non-mission essential personnel
within the allowable Basic Allowance for Housing rates.
A11.5.2.1.2. There is suitable lodging available off base for temporary duty personnel
within the allowable per diem.
A11.5.2.1.3. In other situations where compensation can potentially be made to
members in lieu of providing a facility on base.
A11.5.2.2. A market analysis of the local hotel or housing market is normally conducted
to assess the viability of a Direct Compensation alternative.
AFMAN65-506 6 SEPTEMBER 2019 119
A11.5.3. The above-mentioned alternatives are the ones most frequently addressed in
construction and repair economic analyses. However, an analyst should always aggressively
pursue all reasonable alternatives, since the final decision can be no better than the available
choices. Throughout the economic analysis process, the analyst will continually consider
accepting new alternatives and discarding old ones.
A11.5.4. Occasionally, after a complete review of the facts and circumstances pertaining to
the proposed project, the analyst may conclude that there is only one feasible alternative. In
this case, a waiver from the requirement for an economic analysis is required. This waiver
must follow the process described in this manual and in AFI 65-501. (T-1). Cost is not a basis
for infeasibility. If cost is the only aspect of an infeasibility determination, that alternative
must remain and an economic analysis must be developed. (T-2).
A11.5.5. Disposing of Existing Facilities. If the alternative involves replacing the current
facility either by means of new construction, private sector development, or a long-term lease,
the issue of what to do with the existing facility must be addressed. (T-2). There are three
common disposal practices:
A11.5.5.1. Converting the facility to another use. This is normally only an option if an
existing need could be met by the conversion. Conversion and operating costs are assumed
to be borne by the new occupant and are not included in the economic analysis.
A11.5.5.2. Demolishing the facility. This option is considered whenever the existing
facility is substandard, its site is required for a new facility, or if there is no other potential
use for it. Facilities are a resource, however, so before demolition is selected, a review of
all possible current or future uses needs to be conducted. The cost of demolition is included
in the analysis.
A11.5.5.3. Placing the facility in caretaker status. This option involves closing up the
facility and preserving it for potential future use by providing periodic maintenance to
preserve its structural integrity; "mothballing" and "pickling" are colloquial terms for
caretaker status. The sustainment costs associated with caretaker status are included in the
analysis.
A11.6. Conducting the Cost Analysis. This section discusses the cost analysis required in the
economic analysis. The costs and savings associated with each alternative under consideration
must be quantified and included in the analysis calculations. (T-2).
A11.6.1. All incremental costs expected to be incurred over the economic life assumed for
each alternative, except sunk costs, are included in the life cycle cost analysis. Examples of
sunk costs could include: project planning, preliminary design, and preparation of the
economic analysis itself depending on the phase at which the analysis is being completed.
Design costs are considered sunk if they are obligated or spent prior to selection of an
alternative. The amount of design costs that are considered sunk will vary based on the project.
Wash costs are optional to include.
A11.6.2. Construction and Other One-Time Costs. Most one-time costs occur early in a
project's life cycle although they can occur at any point, e.g., disposal costs. Construction costs
are usually the most significant example of one-time costs. However, all other one-time costs
are also considered.
120 AFMAN65-506 6 SEPTEMBER 2019
A11.6.2.1. Construction/Improvement Costs. Construction/Improvement costs include
design fees for the primary facility or building addition, demolition, site preparation,
utilities, roads and pavements, contingencies, and Supervision, Inspection, and Overhead.
Since the largest percentage of the project cost is determined by the scope of the
Improvement or New Construction project, it is imperative that all primary and support
costs are considered in the economic analysis. Equally important is the need for accurate
and complete cost estimating capabilities. Parametric cost estimating systems, such as the
Parametric Cost Engineering System (PACES), allow the analyst to readily compile costs
for multiple project construction or renovation alternatives. It is important for users of a
parametric cost model to understand how changes to model inputs will impact estimated
cost.
A11.6.2.2. Construction/Improvement costs are included on the Department of Defense
Form 1391 and attachments. The Department of Defense Form 1391 and attachments for
an economic analysis include:
A11.6.2.2.1. The project title, project number, and alternative name.
A11.6.2.2.2. The scope of the estimate in square feet or square meters (noting which
unit is used).
A11.6.2.2.3. A brief description of the costing methodology or estimating system used.
A11.6.2.2.4. Dated sources for variables, such as area cost factors and escalation
factors.
A11.6.2.2.5. The base year of the project cost.
A11.6.2.2.6. Authority signature for the estimate.
A11.6.3. The estimate shows all interim calculations so that the values can be tracked from
the source data to the total project cost appearing on the Department of Defense Form 1391
and in the Life Cycle Cost Report. Clear documentation speeds review of the analysis. In
addition, a clearly documented Department of Defense Form 1391 can be easily updated when
the source data changes or when the project is changed for a different program year.
A11.6.4. When compiling project costs, special attention is also given to ensure that all costs
associated with a renovation alternative, such as asbestos abatement, lead-based paint
remediation, environmental compliance, etc., have been considered.
A11.6.5. Other One-Time Costs. Accurate assessment and inclusion of other one-time costs
is imperative to ensure a complete analysis. Examples (many of which can be found in
Housing AFIs 32-6001, Family Housing Management, 32-6005, Unaccompanied Housing
Management, 32-6004, Furnishings Management Program) of one-time costs include:
A11.6.5.1. Moving and storage of furnishings and equipment when users are relocated.
A11.6.5.2. Disposal and replacement of furnishings and equipment.
A11.6.5.3. Lease payments made for temporary space.
A11.6.5.4. Temporary contracting out of the requirement.
A11.6.5.5. Tenant build-out requirements involving renovations to the temporary space in
order to make the facility meet the users' needs.
AFMAN65-506 6 SEPTEMBER 2019 121
A11.6.6. All attempts should be made to time facility replacement or improvement
construction activities to correspond with the expected requirement. However, even with the
best scheduling attempts, temporary accommodations may be required. Occasionally,
contracting out the requirement may be feasible and economical. In other cases, users may
require temporary accommodations. For renovation alternatives, this may involve moving the
users into temporary leased space while the existing facility is being improved and, following
completion of the project, moving into the completed facility. Lease rates are discussed below.
Moving and storage costs (drayage) can be obtained from the base transportation office. The
Interstate Commerce Commission can also provide approximate moving costs based on
weight, as well as requirements for cartons and custom-built crates. In addition, some tenant
build-out, such as partitions, power, and telecommunications, may be required to meet the
users' requirements.
A11.6.7. The improvement or replacement of a dormitory can result in some unique one-time
costs, such as:
A11.6.7.1. Reconnection fees associated with telephone and cable television service.
A11.6.7.2. Moving and storage of personal belongings for dormitory residents.
A11.6.7.3. Basic Allowance for Housing payments made to personnel in temporary
housing off base.
A11.6.8. As with other construction and repair projects, all attempts should be made to
schedule or phase dormitory improvements or replacements so as to minimize these one-time
costs.
A11.6.9. Recurring Costs. Recurring costs are the repeated costs required to operate and
maintain a facility. They are generally calculated on an annual or periodic basis.
A11.6.9.1. Examples of recurring costs include:
A11.6.9.1.1. Maintenance and repair of the facility.
A11.6.9.1.2. Utilities, such as electricity, natural gas, steam, water, and sewer.
A11.6.9.1.3. Personnel costs, such as building management, lease management,
custodial service, and security service.
A11.6.9.1.4. Lease costs
A11.6.9.1.5. Miscellaneous costs, such as grounds maintenance, landscaping, and
snow removal.
A11.6.9.2. Maintenance and Repair Costs. Maintenance and repair costs include both
annual maintenance and repair and periodic maintenance and repair. Annual maintenance
and repair expenses include preventive maintenance, unscheduled plumbing and electrical
repairs, and minor structural repairs that are required to ensure a safe and efficient work or
living environment. Periodic maintenance and repair expenses include major repairs to
building components, such as roof systems, electrical systems, heating ventilation and air
conditioning, plumbing fixtures, and interior finishes. These costs can be estimated based
on the expected life of the building system.
A11.6.9.2.1. Annual maintenance and repair costs
122 AFMAN65-506 6 SEPTEMBER 2019
A11.6.9.2.1.1. When an existing facility is associated with the Status Quo
alternative, historical annual maintenance and repair costs typically are used to
project future annual maintenance and repair costs in the economic analysis. The
analyst should collect and review at least three years of data in order to develop a
valid estimate.
A11.6.9.2.1.2. An industry reference that provides maintenance and repair cost per
square foot for a given facility type can also be utilized.
A11.6.9.2.1.3. Renovation and replacement alternatives typically have lower
annual maintenance and repair costs than the Status Quo alternative. Therefore, the
historical maintenance and repair cost data are normally adjusted downward by an
assumed percentage (commonly based on engineering judgment) for the
improvement and replacement alternatives. These assumptions must be clearly
stated in the analysis. (T-2). In the absence of information specific to the current
project, the Building Age Multiplier factors presented in Figure A11.6 may be used
to adjust annual maintenance and repair costs over the life of the improved or new
facility. If an assumption is made that there is no increased annual maintenance
cost associated with building age, then that assumption should be explicitly stated
and justified.
Figure A11.6. Building Age Multiplier Factors.
A11.6.9.2.2. Periodic maintenance and repair costs:
A11.6.9.2.2.1. Periodic maintenance and repair schedules are based on the
expected life of the equipment or fixtures. Civil Engineering can provide the date
the item was last replaced so that the analyst can project future schedules and costs
under the Status Quo alternative. Renovation and new construction alternatives
generally begin with all new equipment; hence, replacement schedules are based
on the construction date. It is important to remember that scheduled intervals will
often vary based on local conditions. For example, the salt air in marine
environments corrodes and shortens the expected lives of exterior mechanical units,
roof membranes and drainage systems, window frames, exterior doors, etc. Figure
A11.7 displays the generally accepted useful lives of various equipment and
fixtures.
AFMAN65-506 6 SEPTEMBER 2019 123
Figure A11.7. Life Cycles of Selected Building Systems.
A11.6.9.2.2.2. Periodic maintenance and repair costs can be estimated from local
prices or by using the cost of any recent replacement of similar items, including
appropriate labor fees. If such cost data is unavailable, commercial sources, such
as R.S. Means, Whitestone or Dodge Cost Data can be used and documented.
Another possible source would be comparable maintenance and repair costs from
another installation for a similar facility.
A11.6.9.3. Utility Costs. Utility costs include the expenses associated with the provision
of utility services, such as: Electricity, Natural gas or Oil, Steam, Water, Sewage, and
Telecommunications.
A11.6.9.3.1. Figure A11.8 presents an example of the technique used to estimate
annual electricity costs for all alternatives based on an area (square footage) basis; other
energy-consuming utility costs can be similarly calculated. The analyst uses annual
utility usage and facility size for similar facility types to estimate utility costs for the
proposed facility. The most accurate estimates of utility costs are available when bases
can meter utility usage at the facility level. Utility bills or Defense Utility Energy
Reporting System reports provide total utility consumption figures for the facility. The
Defense Utility Energy Reporting system can also provide the necessary area figures.
Civil Engineering is the best source for this data. If possible, usage rates from three
previous years are averaged after adjusting them to the base year of the economic
analysis. IHS Energy escalation Indices are used to escalate energy costs to the base
year. This data is available from SAF/FMC.
A11.6.9.3.2. Non-energy-consuming utilities such as sewage, and telecommunications
can also be calculated based on a three-year average. Since improvement or
replacement usually will not influence these usage rates, status quo values can be used
for all alternatives where the same users will move back into the facility. The analyst
should escalate non-energy costs to the base year using an appropriate escalation rate.
124 AFMAN65-506 6 SEPTEMBER 2019
Figure A11.8. Calculation of Annual Electricity Costs on an Area Basis.
A11.6.9.4. Personnel Costs. Personnel costs include the costs of staffing building
services, such as building management, lease management, and security.
A11.6.9.4.1. Personnel costs are calculated as the product of the number of personnel
and their appropriately burdened salary.
AFMAN65-506 6 SEPTEMBER 2019 125
A11.6.9.4.2. As noted in paragraph A11.6.1., the analyst should only include
incremental costs (additional costs that will result from an alternative being selected).
The following examples apply the incremental cost concept to personnel costs. If the
Air Force had to create a manpower position in order to support the facility, then the
Air Force will incur additional personnel cost as a result of the facility and the cost
should be included in the analysis. Conversely, if the building will require more time
within normal duty hours from an individual already employed by the Air Force, then
the Air Force did not incur additional personnel cost unless overtime pay is required.
In this second example, the increased hours should be assessed in the benefits section.
A11.6.9.4.3. Different alternatives or alternative facility designs can result in different
personnel costs. For example, a facility with a small number of exterior entrances may
require fewer security personnel than a design with numerous entry points or multiple,
unconsolidated facilities.
A11.6.9.4.4. For transient quarters, personnel costs also include maid service and the
front desk operation. Consult the AFI 65-503, US Air Force Cost and Planning Factors
for the most recent tables of Military and Civilian Compensation. If more specific data
than AFI65-503 is available, use that information.
A11.6.9.5. Contract Operations and Maintenance Costs. Contract costs include the costs
for contracts needed to keep the facility in working order. Contract costs can vary based
on building design. For example, a dorm with exterior walkways may require fewer
custodial personnel than a dorm with interior corridors.
A11.6.9.5.1. Many building services could be estimated either under personnel costs,
if the services are provided by base personnel, or under contract costs, if the services
are provided by a contractor.
A11.6.9.5.2. For administrative facilities, the median cost per square foot for building
services can be obtained from the Building Owners and Manager's Experience
Exchange Report (BOMA International, Washington, DC, (202) 408-2662).
A11.6.9.6. Lease Costs. Lease costs are associated with using off-base facilities on either
a temporary or long-term basis. If there is an existing Air Force lease of similar space off
base, then that lease rate per square foot can be used to estimate future lease costs for either
temporary space or a long-term requirement under a Government Lease Alternative. If
there is not an existing Air Force lease, then the General Services Administration lease
rates for the appropriate geographic area are used. The base office responsible for real
property management can normally provide the General Services Administration space
rates. For most facility types, Air Force leases are negotiated and managed by the General
Services Administration. General Services Administration rates are provided by functional
space type (e.g., office, conference, storage, laboratory, and industrial). General Services
Administration lease rates are typically gross leases--that is, the lease rate includes
reimbursements for services like maintenance and utilities. Gross leases are also known as
“full service” leases. The Air Force has authority to negotiate and manage leases directly
for land and unique, special-purpose facilities.
126 AFMAN65-506 6 SEPTEMBER 2019
A11.6.9.7. Direct Compensation
A11.6.9.7.1. For a dormitory facility, the primary cost element associated with a Direct
Compensation alternative is Basic Allowance for Housing payments. Basic Allowance
for Housing payments are based on grade and geographic location. Basic Allowance
for Housing data can be obtained from the Defense Travel Management Office
https://www.defensetravel.dod.mil/site/bah.cfm.
A11.6.9.7.2. For a transient quarters facility, the primary cost element associated with
a Direct Compensation alternative is lodging per diem payments. The Defense Travel
Management Office can provide lodging per diem rates for the geographic area
https://www.defensetravel.dod.mil/site/perdiemCalc.cfm. Where there are no
existing transient quarters, the billeting office can also provide the number of
"Certificates of Non-Availability" that have been issued over the last 3 years.
A11.6.9.8. Basic Allowance for Housing or per diem payments may also be incurred when
users need to find temporary accommodations off base during a renovation or construction
project for dormitory or transient quarters. These costs would be incurred in accordance
with the construction schedule.
A11.6.9.9. Figure A11.9 summarizes the suggested data sources for obtaining the data
required to conduct a construction or repair economic analysis.
Figure A11.9. Summary of Data Sources for Construction and Repair Economic Analyses.
A11.6.10. Impact of Project Schedule on Cost.
A11.6.10.1. The project schedule provides information about project phasing and facility
occupancy under each alternative. Many costs associated with the existing situation
continue to be incurred during the construction period. In general, reduced costs, such as
lower utility costs, cannot be realized until the new facility is occupied and the old facility
has been disposed.
AFMAN65-506 6 SEPTEMBER 2019 127
A11.6.10.2. Where the project schedule allows for phased occupancy, costs such as annual
maintenance and repair and utilities are pro-rated. The occupancy or “move-in” date may
vary for some alternatives due to different time factors associated with the construction
period, approvals, and the solicitation process.
A11.6.11. Other Cost Considerations
A11.6.11.1. The concept of present value is fundamental to the economic analysis. Present
value calculations allow comparison of different dollar amounts received or expended
during different time periods. In addition to presenting the costs in either then-year or
constant-year dollars, the costs for each alternative must be presented in present value
terms. (T-2).
A11.6.11.1.1. Discounting is the technique used to determine the present value of
future cash flows. Discounting is further explained in Chapter 4 of this manual. The
Air Force normally uses a mid-year discounting convention. The mid-year discounting
calculation is illustrated in Attachment 7 of this manual.
A11.6.11.2. Uniform Annual Cost. Uniform Annual Cost is a technique used to account
for alternatives having different economic lives. It is required for real property
construction and repair economic analyses (T-2).
A11.6.11.2.1. Uniform Annual Cost uses a life cycle cost to measure the cost of each
alternative. In addition, construction and repair economic analyses are required to
report the life cycle cost of each alternative using the Uniform Annual Cost Method,
and the Terminal Value Method as described in Chapter 4 of this AFMAN.
A11.6.11.2.2. The Uniform Annual Cost Method is further illustrated in Attachment
7. Reporting costs in terms of the Uniform Annual Cost Method and the Terminal
Value Method provides the Air Force with methods of comparing the costs of
alternatives with different economic lives.
A11.7. Conducting the Benefits Analysis. A benefits analysis takes into account the non-
monetary aspects of each alternative in an economic analysis. A benefits analysis is required in
all economic analyses.
A11.7.1. There are a variety of ways benefits can be evaluated including narrative description,
ordinal measurement and quantitative measures. Chapter 5 of this manual provides details on
conducting benefit analyses.
A11.7.2. The financial management analyst is responsible for conducting the benefits
analysis. However, input should be provided by a variety of installation functions including,
but not limited to, the primary user or beneficiary of services from the facility, civil
engineering, services, security police, transportation, and other appropriate agencies. One
effective approach is to convene a "roundtable" discussion with all participating organizations
to determine benefit categories and elements and to evaluate the benefits by alternatives.
A11.7.3. The financial management analyst should prepare a source document for the benefits
analysis showing participants, assumptions, rationale for benefit selection, and sources. This
document must be included in the economic analysis. (T-2).
128 AFMAN65-506 6 SEPTEMBER 2019
A11.7.4. Examples of typical benefits are presented in Figure A11.10 Note that the list in
Figure A11.10 is by no means exhaustive, but it does include many of the benefits which are
normally considered when evaluating construction and repair projects.
Figure A11.10. Benefits for Consideration in Construction and Repair Projects.
AFMAN65-506 6 SEPTEMBER 2019 129
A11.8. Uncertainty Analysis (Sensitivity and Risk Analysis).
A11.8.1. A sensitivity analysis is required in all economic analyses (T-1). Sensitivity analysis
identifies key assumptions and variables within an economic analysis and determines how
changes affect the results of the alternatives relative to each other. For decision makers facing
an investment decision, sensitivity analysis is a tool for determining how changes in costs or
benefits (e.g., due to estimating errors that stem from uncertainty) affect the economic analysis
conclusion and interpretation of results.
A11.8.2. Sensitivity Analyses should be performed on assumptions that drive cost and any
assumptions that have the possibility of significantly changing the relative value of the
alternatives. Chapter 6 of this nanual provides additional information on how to conduct a
sensitivity analysis.
A11.8.3. Risk Analysis A risk analysis is an evaluation of unfavorable events or outcomes
and assesses uncertainty in a manner different from sensitivity analysis.
A11.8.4. A risk analysis is not required in real property construction and repair economic
analyses, but should be included when directed by the decision-maker or when the level of risk
associated with any alternative has a reasonable likelihood of being a key consideration for the
decision maker. Chapter 6 of this manual provides additional information on how to conduct
a risk analysis.
A11.9. Summary and Comparison of Alternatives. This section is the key to a meaningful
economic analysis. The analyst summarizes the analysis, compares the alternatives and provide
some interpretation of the results for the decision maker.
A11.9.1. Summarizing Alternatives
A11.9.1.1. Provide summary tables for the cost analysis, benefit analysis, and uncertainty
analysis for areas where the analyses have been expressed in quantitative terms.
A11.9.1.2. The cost summary should include a table(s) with the present value of the
alternatives, new funding required by alternative, and any other financial measures used to
evaluate the alternatives.
A11.9.1.3. Benefits - The benefit summary should include a summary table if the benefits
were measured using: physical counts, an index/ratio, or a rating scale. If benefits were
evaluated using narrative descriptions, then those descriptions should be summarized in
this section.
A11.9.1.4. Uncertainty - A description of the sensitivity analyses should be included in
this section. This also is the appropriate section to summarize results for the risk
assessment. If risk was measured quantitatively, a table should be included.
A11.9.2. Comparing Alternatives
A11.9.2.1. The present value of costs and the Uniform Annual Costs must be compared
across alternatives and any resulting cost differences addressed. (T-2).
A11.9.2.2. As a minimum, the benefits must be narratively compared across alternatives.
(T-2). In certain analyses, comparison of benefit scores is also appropriate.
130 AFMAN65-506 6 SEPTEMBER 2019
A11.9.2.3. The overall relative strengths and weaknesses of each alternative are required
to be discussed narratively in this section.
A11.9.3. The interpretation of the results should flow logically and be consistent from the rest
of the analysis.
A11.9.3.1. For example, an economic analysis for transient quarters could demonstrate
that continuing to pay per diem to transient personnel is the least cost alternative.
A11.9.3.2. However, if off-base lodging is remote and a significant number of the
transients are distinguished visitors, the benefits analysis may demonstrate that
construction of new quarters satisfies the objective far more effectively.
A11.10. Documenting the Results of the Economic Analysis. An economic analysis must be
documented in an economic analysis report to allow complete replication by reviewers. (T-2).
This section provides guidance on how to document an economic analysis. Figure A11.11 lists
the required elements.
Figure A11.11. Documentation Elements.
A11.10.1. Certificate of Satisfactory Economic Analysis For the Certificate of
Satisfactory Economic Analysis, follow the procedure and format provided in
Attachment 3 of this manual.
A11.10.2. Executive Summary For the Executive Summary, follow the format in
Section A11.11 of this manual.
A11.10.3. Table of Contents A Table of Contents outlining the organization of the
economic analysis is placed after the Executive Summary.
A11.10.4. Background/Objective/Scope The objective and an abbreviated version of
the background will be included in the executive summary to orient the reader to the
analysis. (T-2). A more thorough background will be included in the body of the economic
analysis document in addition to the objective and a description of the scope of the analysis.
(T-2).
AFMAN65-506 6 SEPTEMBER 2019 131
A11.10.5. Facts/Assumptions/Ground Rules All economic analyses must include a list
of the assumptions made. (T-2). These assumptions must be clearly stated so evaluators can
understand the level of uncertainty and risk inherent in the economic analysis results. (T-2). It
is also important to include the source for each assumption.
A11.10.6. Alternatives - Detailed descriptions of each of the reasonable alternatives
addressed in the economic analysis are also included in the economic analysis executive
summary report. Figure A11.12 presents a checklist by alternative of the information that is
included in the project description. Justification for alternatives that were considered but
dismissed as infeasible are also presented in this section.
Figure A11.12. Description of Alternatives Construction and Repair Economic Analyses.
A11.10.7. Source and Derivation of Costs
A11.10.7.1. The methodology used for the interim calculations can be presented
narratively, or in tables or charts. Tables and charts can facilitate the review of the
economic analysis for evaluators. It is very important to include the source and any interim
calculations conducted for all estimates and data used in the economic analysis. Therefore,
this section will refer the reader to the appropriate signed source documents in Appendix
B and interim calculations in Appendix C of the economic analysis.
A11.10.7.2. Any assumptions that were used in the derivation of the cost estimate are also
reiterated here. For example, the derivation of annual maintenance and repair costs might
read like this: “Annual maintenance and repair costs for the existing facility were
based on historical data provided by the Planning Department of the Civil
Engineering Squadron (Appendix B). The data were adjusted to TY22 dollars
(Appendix C). Annual maintenance and repair costs for the renovation alternative
were assumed to be 10 percent less than the Status Quo alternative. Annual
maintenance and repair costs for the new construction alternative were assumed to
be 15 percent less than the Status Quo alternative. These assumptions were based on
interviews with Civil Engineering personnel and are documented in the Civil
Engineering Source Document dated 29 April 20XX. (Appendix B).”
132 AFMAN65-506 6 SEPTEMBER 2019
A11.10.8. Source and Derivation of Benefits: This section explains the methodology used
to develop the benefit analysis. The discussion on benefits analysis includes:
A11.10.8.1. A description of each benefit element.
A11.10.8.2. A discussion of the method used to obtain data and analyze the benefits (e.g.,
interviews, survey) to include the names and organizations of those who provided benefit
information. If the benefits were scored, include a discussion of how the weights and
values were calculated.
A11.10.8.3. Results of the benefit analysis by alternative to include rankings for non-
narrative analyses.
A11.10.8.4. When feasible, include a table summarizing the benefits by alternative.
A11.10.9. Uncertainty (Sensitivity Analysis and Risk Analysis) The Sensitivity Analysis
results will be included in the economic analysis. (T-1). If the results of any sensitivity
analysis indicates a change in the alternative rankings, then this fact will be discussed. The
results of any risk assessment will also be included.
A11.10.10. Comparison of Alternatives and Interpretation of Results In this section,
the analyst will provide a comparison of the alternatives and interpret the results. (T-2).
The executive summary will contain an abbreviated form of this section as a conclusion. (T-
2).
A11.10.11. Appendices The economic analysis appendices include the following:
A11.10.11.1. Appendix A includes the Department of Defense Form 1391 for each
alternative.
A11.10.11.2. Appendix B includes the Source Documents used to build the analysis. All
of the signed source documents and supporting data are presented, including the name and
phone number of points of contact.
A11.10.11.3. Appendix C includes the interim calculations for the analysis. All of the
worksheets used in calculating utility, maintenance, moving, temporary leases, personnel
costs, BAH for military personnel, per diem for traveling personnel, and other estimates,
as well as inflation and escalation adjustments are presented in this appendix.
A11.11. A sample Executive Summary for a MILCON Economic Analysis is provided
below. Even though the content of this sample applies strictly to MILCON, the format can be
applied to other comparative analyses. Note that only the Executive Summary is provided below,
not the entire analysis report. More details on the cost analysis, benefit analysis, and uncertainty
analysis would be included in the body of the document.
A11.11.1. The Executive Summary includes a description of all reasonable alternatives.
Including a description of reasonable alternatives that are infeasible will inform subsequent
readers of why an alternative was excluded from further consideration.
A11.11.2. The cost table includes: new funding required, life cycle costs, and Uniform Annual
Costs. The life cycle costs are only those costs relevant for comparative analyses. For
example, they do not include sunk costs and may not include wash costs.
AFMAN65-506 6 SEPTEMBER 2019 133
A11.12. A weighted benefit summary was included in the Executive Summary to: Reflect
that a weighted benefit technique was used as part of the comparative analysis. Following the
sample Executive Summary, a second example of a benefit analysis summary was provided that
could be used in an Executive Summary. The second example of a benefit analysis summary is
for when a narrative benefit technique is used in the comparative analysis. Please note that the
Executive Summary only contains a summary of the benefit analysis. A more thorough description
of the benefit analysis should be included in the main body of the document.
A11.13. The sample Executive Summary includes a recommendation.

EXECUTIVE SUMMARY
Installation/MAJCOM: Sample Air Force Base (AFB), Any State/Air Mobility Command
(AMC)
Project Title: 237
th
Aeromedical Evacuation Squadron Facility
Project Number: 1024223
Project Objective: Provide facility at Sample Air Force Base (SAFB) that meets the needs of
the 237
th
Aeromedical Evacuation Squadron
Background
The 237
th
AES conducts aeromedical evacuation missions spanning the continental United
States, Europe, the Pacific and the Middle East. A Strategic Basing Decision was approved
by the Secretary of the Air Force (SecAF) in May 20XX to relocate the 237
th
AES from Old
Air Force Base to Sample Air Force Base. This relocation aligns the 237
th
AES with the
Air Mobility Wing at SAFB.
The 237
th
AES is manned by flight medical personnel, plus medical, logistics, and
radio/communications technicians. This incoming unit will need secure space for unit
operations and climate-controlled storage to relocate its 57 officers, 110 enlisted, one civilian,
and all associated mobility support equipment.
Alternatives Considered
Alternative 1: Status Quo (Infeasible) The 237
th
AES is a new mission at SAFB and no
facility exists to accommodate the squadron without modifications. Therefore, this
alternative is considered infeasible and was not analyzed further.
Alternative 2: Renovation
Under this alternative, Building 241 on SAFB would be used
to house the incoming 237
th
AES. The building would require a major renovation to
accommodate the 237
th
AES. The renovation would replace the old, leaking roof with a new
standing seam metal roof, replace the original interior doors, install new floor coverings,
repaint the exterior of the facility, replace the ceiling throughout the facility, replace all
electrical wirings, install energy efficient lighting and controls, replace raised flooring,
remove curb slope entrance at the second floor restrooms, replace all original windows with
those approved for antiterrorism/force protection, install fire detection and suppression
systems as required. Building 83 would be used for equipment storage. The renovation
project is estimated to begin in June of 2019 and is estimated to be completed by September
of 2020.
AFMAN65-506 6 SEPTEMBER 2019 135
Alternative 3: New Construction
-
Under this alternative, a new purpose-built facility
would be constructed with 29,999 SF to accommodate the 237
th
AES and B83 would be
used for equipment storage. Under this alternative, the project is estimated to begin in
March of 2022 and would be completed by January of 2023. Since there is no currently
existing facility, disposal costs will not be incurred.
Summary of Analysis Results
Summary of Costs - A cost summary is provided in the table below. Renovate has a
significantly lower investment cost and a lower life cycle cost. Consistent with the lower
investment and life cycle cost, the Uniform Annual Cost for renovation is also lower than the
Uniform Annual Cost for new construction.

Attachment 12
ECONOMIC IMPACT ANALYSIS
A12.1. Introduction. By its very presence in local communities, both in the continental US and
around the world, each Air Force installation increases economic output of its host community
thru local spending on goods and services. In addition, individuals who work on an installation
spend their own money in the local community on things like rent, food and entertainment. These
expenditures have an impact on the local economy that can be quantified using an Economic
Impact Analysis (EIA). In turn, the EIA can be an important tool for installation leadership in
interactions with civic leaders.
A12.2. Background. An EIA is an estimate of an installation’s economic impact on its host
community. This chapter provides a methodology, guidance and instructions for estimating an
installation’s economic impact in terms of dollars and jobs.
A12.2.1. The requirement to complete an EIA by Air Force installations, units, or MAJCOMs
is determined by the MAJCOM Headquarters or installation commander. For installations that
do produce an EIA, the guidance in this chapter is provided to ensure a valid methodology is
used and to aid in consistency and comparability across installations.
A12.2.2. SAF/FMC developed an Excel
®
estimating template to assist producers of EIA and
to facilitate consistency of EIA across the Air Force. This Excel
®
template/spreadsheet is
available on the SAF/FMCE SharePoint
®
page, to which a link is provided on the SAF/FMCE
page of the Air Force Portal. The Installation and Mission Support Center Resource
Management Cost Division may also be a useful reference.
A12.2.3. While it is possible to calculate economic impact without multipliers, the Air Force
primary approach uses multipliers. An allowable alternate approach is to calculate the
economic impact without using multipliers. The analysis should state whether or not
multipliers have been included. If an installation does include economic multipliers, the
analyst should use the economic multipliers from the Bureau of Economic Analysis.
Multipliers for many installations are provided in the Excel
®
template.
A12.2.3.1. The Bureau of Economic Analysis multipliers are developed using the
Regional Input-Output Modeling System (RIMS II) and the resulting multipliers are called
final-demand multipliers. Only changes in purchases made by final users are used with
final-demand multipliers. A final-demand change refers to goods and services sold to final
users. Final users are people and organizations that purchase a finished or final product.
For example, a bakery that buys ingredients (e.g., flour, sugar, eggs) to make bread and
pastries is not considered a final user; the customers who buy the final product (i.e., the
bread and pastries) are the final users. In most cases for Air Force EIA, dollars associated
with final users are limited to Appropriated Fund and Working Capital Fund expenditures
and payroll.
A12.2.3.1.1. Accounting for Government Expenditures and Payroll The Bureau of
Economic Analysis does not include a government multiplier that is suitable to use in
an EIA. Instead, analysts will have to break out expenditures by type (e.g.,
construction, utilities, payroll). This approach will then require the application of
multipliers by expenditure type as described in section A12.4 of this manual.
140 AFMAN65-506 6 SEPTEMBER 2019
A12.2.3.1.2. Examples of final user expenditures are: (1) construction funded by
appropriated funds, (2) utilities funded by appropriated funds, (3) supplies funded by
appropriated funds, (4) any other good or service funded by appropriated funds, and
(5) purchases funded by a Working Capital Fund.
A12.2.3.1.3. Examples of final user payroll are: (1) military pay, (2) civilian pay, (3)
Non-Appropriated Fund employee payroll funded by appropriated funds, (4) Army &
Air Force Exchange Service and Defense Commissary Agency (DeCA) employee
payroll funded by appropriated funds, (5) other employee payroll funded by
appropriated funds and (6) employee payroll funded by a Working Capital Fund.
A12.2.3.2. Some expenditures are purposefully not included when calculating the
economic impact of an installation on the local area. That is because they do not represent
a final-demand change caused by the Air Force installation.
A12.2.3.2.1. Expenditures that are not final user should not be included in expenditure
amounts to which the multipliers will be applied. These intermediate expenditures are
accounted for by the multiplier itself. They are similar to purchases made by a military
person or government civilian at a local community department store, grocery store,
etc. Likewise, a housing privatization expenditure is similar to the cost of construction
for a newly constructed house off-installation that is being rented to a military member.
In this case, the economic impact is accounted for under the Basic Allowance for
Housing (BAH) payment, not the privatized construction cost.
A12.2.3.2.2. Examples of expenditures that are not final user include: (1) Non-
Appropriated Fund employee payroll not funded by appropriated funds, (2) Non-
Appropriated Fund activity expenditures not funded by appropriated funds, (3) housing
privatization expenditures not funded by appropriated funds, (4) payroll and
expenditures of a business that physically resides on an installation, such as a bank,
credit union or tenant restaurant.
A12.3. Data Collection. The SAF/FMC EIA tool requires a variety of data elements (described
below). The data elements are organized into tables to help analysts organize the data. Each table
element is intended to be self-explanatory. Annualize all expenditures for payroll, contracts,
construction and other procurements that are spent over more than one FY. If actual expenditures
are not available, distribute the contract amount for a project or service evenly over the number of
years of the contract. Input the annualized number, not the full contract value. Include tenant
organizations to the extent that they impact the local economy. Who and what amount to include
will not be an exact science. That being said, it is key to document which organizations are
included in the analysis. The paragraphs under paragraph A12.3 (this section) refer to tables in
the Excel
®
template as a way to organize data collection. Figure A12.1 summarizes the data
collection requirements.
A12.3.1. Personnel.
A12.3.1.1. Input Table 1 Number of Personnel. The number of personnel table in the
Excel
®
template will show the number of personnel employed locally by the installation or
activity, regardless of where the servicing personnel or payroll offices are located.

template will show the installation payroll expenses impacting the local area. The many
people who work on Air Force installations (military personnel, civilian personnel and
host-nation civilian employees) increase the economic output of the local community by
spending some portion of their pay on such items as rent, restaurants, entertainment and
daily necessities.
A12.3.1.2.1. Payroll is defined as gross income including basic pay, benefits and
allowances. Do not include retirement funds accrued or employer contributions that
are not immediately available to the employee.
AFMAN65-506 6 SEPTEMBER 2019 143
A12.3.1.2.2. When appropriate, or when specific cost information is not available, use
cost factor tables from AFI 65-503. The current cost factor tables are available on the
SAF/FMCE SharePoint

page, to which a link is provided on the SAF/FMCE page of
the Air Force Portal. Table references that follow refer to AFI 65-503.
A12.3.1.3. The community on an Air Force installation consists of many different kinds
of employees funded by appropriate funds. The intention is to count all these personnel in
the EIA. Personnel categories to include:
A12.3.1.3.1. Military Pay.
A12.3.1.3.1.1. Regular Air Force.
A12.3.1.3.1.1.1. Data Source: Servicing Financial Services Office. An

A12.3.2. Input Table 3 Expenditures by classification. Table 3 in the Excel
®
template
will show the installation expenses for Construction, Services, and Procurement of Materials,
Equipment and Supplies. This is spending in the local community by installation units,
organizations and activities. An Air Force installation increases economic output of its host
community through spending on locally-purchased materials, supplies, equipment and
contracts. Installations also spend locally for services and construction contracts as well as
utilities and many other items, large and small. In addition to spending by official Air Force
units, recreational and other supporting organizations also make purchases off-installation, as
do tenant vendors, banks and many other unofficial activities on the installation.
A12.3.2.1. Locally produced goods and services This category includes goods and
services that are not only purchased from local suppliers, but also produced locally.
A12.3.2.1.1. Construction expenditures. Include the following construction-related
expenditures as appropriate (suggested source: Civil Engineer function staff):
A12.3.2.1.1.1. MILCON Program.
A12.3.2.1.1.2. Military Family Housing Construction.
A12.3.2.1.1.3. Military Family Housing Operations and Maintenance (O&M).
A12.3.2.1.1.4. Construction-related Operations & Maintenance. Include only
those costs associated with contract construction (i.e., minor construction,
architectural and design fees, and real-property maintenance contracts).
A12.3.2.1.1.5. Non-Appropriated Fund Construction.
A12.3.2.1.1.6. Working Capital Fund Construction.
A12.3.2.1.2. Locally produced non-construction expenditures.
A12.3.2.1.2.1. Include all expenditures for goods and services that were produced
in the local area.
A12.3.2.1.2.2. Examples include: utilities (e.g., Cost Element Code 2332xxx for
commercial utilities, Legacy: Element of Expense 480xx), warehousing and
storage, printing, telecommunications, internet, real estate services (leasing, etc.),
Advisory and Assistance Services, Administrative and Support Services, waste
management, educational services, lodging services and hospital services.

A12.3.2.1.2.3.2. Army & Air Force Exchange Service and Defense
Commissary Agency. Use appropriated fund expenditures only. Information
may be obtained directly from the installation manager. If unable to determine
how much appropriated fund spending is local, the analyst may make a reasoned
estimate.
A12.3.2.1.2.3.3. Medical. Ensure that any local procurement spending of Air
Force funds in the medical appropriation are included. The local medical
facility may also help determine the amount of local TRICARE spending in the
local economy.

A12.3.2.1.2.3.4. Non-Appropriated Funds. Information on local procurements
may be obtained directly from the local Non-Appropriated Funds resource
management office. If unable to determine how much of Non-Appropriated
Funds spending is local, the analyst may make a reasoned estimate.
A12.3.2.1.2.3.5. Working Capital Fund. Installation budget office.
A12.3.2.1.2.3.6. Education.
A12.3.2.1.2.3.6.1. Department of Defense Education Activity. Information
may be obtained directly from the local the Department of Defense Education
Activity. If unable to determine how much of Department of Defense
Education Activity spending is local, the analyst may make a reasoned
estimate.
A12.3.2.1.2.3.6.2. Impact Aid. The Federal Government provides financial
assistance to local school districts to assist with the provision of educational
services to children of Federal employees (in accordance with Title VIII of
the Elementary and Secondary Education Act of 1965 (20 U.S.C. § 7701 et.
seq.)). An allocation should be used if there is more than one military
installation in the economic area (e.g., based on military and civilian
personnel assigned to the installation). Information may be obtained from the
local school district or United States Department of Education, Impact Aid
Programs,
http://www2.ed.gov/about/offices/list/oese/impactaid/index.html or
[email protected]. Contact telephone number is: 202-260-3858.
A12.3.2.1.2.3.6.3. Tuition Assistance. Information may be obtained directly
from the installation Education Office.
A12.3.2.2. Local purchases of goods produced outside the local area.
A12.3.2.2.1. Include local expenditures that are not captured in A12.3.2.1 above.
A12.3.2.2.2. One suggested method of data collection (for Air Force appropriated fund
activities on an installation) is to perform a Commanders' Resource Integration System
(CRIS) and/or Defense Enterprise Accounting and Management System (DEAMS)
retrieval of all expenditures (Accrued Expenditures Paid) incurred in the relevant FY
by Cost Elements (Legacy: Element of Expense and Investment Code). Exclude
expenditures that were not spent locally, like the Air Force Stock Fund and e-commerce
via the Government Purchase Card (GPC) program. Based on location and
circumstances, useful information may be available in contracting and civil engineering
databases. If appropriate, the analyst may assume expenditures were made locally and
include them in the estimate. This is a difficult category of local spending to estimate
and the analyst must exercise the best reasoned judgment.
A12.3.2.3. Temporary Duty/Travel.
A12.3.2.3.1. Include the amount of local spending by individuals Temporary Duty
(TDY) to the installation (suggested source: Installation Lodging office).
AFMAN65-506 6 SEPTEMBER 2019 147
A12.3.2.3.2. Lodging cost: Number of Temporary Duty and Temporary Lodging bed
nights multiplied by the lodging rate. Account for any changes in lodging rates that
occur during the year. Account for bed nights in installation lodging separately from
those in local community lodging due to the differences in lodging rates.
A12.3.2.3.3. Meals and Incidental Expenses (M&IE): A suggested method is to obtain
the number of TDY bed nights and perform the following calculation: B * (M * 0.75).
Where B is the number of Temporary Duty bed nights in local community lodging, M
is the Meals and Incidental Expenses rate, and 0.75 assumes that travelers spend 75%
of their Meals and Incidental Expenses allowances in the local community.
A12.4. Estimate of Economic Impact.
A12.4.1. There are many measures of economic impact (e.g., output, earnings, employment,
value added). This instruction will provide two measures using the data collected. The first
measure will be “output plus payroll.” The “output plus payroll” measure represents the total
dollar change in output that occurs for each additional dollar expended by the Air Force plus
payroll expenditures. The second measure is employment. The employment measure
represents the total change in number of jobs that occurs in all industries for each additional
million dollars expended by the Air Force (expenditures should be normalized to the year of
data upon which the multiplier is based). The below calculations are performed within the
Excel

A12.4.2.1.1.2. To calculate total impact from payroll, add the original payroll
expenditures to the number calculated in paragraph A12.4.2.1.1.1 This step is
taken because the multipliers do not count household payroll as “output” to the

Attachment 13
CLINGER-COHEN ACT ECONOMIC ANALYSES
A13.1. Issues Unique To Clinger-Cohen Act Comparative Analyses.
A13.1.1. The Clinger-Cohen Act requires “…criteria related to the calculation of a Return on
Investment” when considering whether to undertake an investment in information systems.
DoDI 5000.75 provides guidance on how to satisfy the Return on Investment requirement for
Defense Business Systems acquisition programs. DoDI 5000.02 provides guidance on how
to satisfy the Element 6 Return on Investment requirement for all other defense programs.
DoDI 5000.74 - Defense Acquisition of Services provides Clinger-Cohen Act guidance for the
acquisition of contracted services.
A13.1.2. Based on this DoD guidance, the Return on Investment requirement in the Clinger-
Cohen Act will be met either through an Economic Analysis or through a Life Cycle Cost
Estimate. (T-0). This Attachment provides information that is used to determine which type of
analysis is required and when in the acquisition life cycle the analysis is required. It also
provides information specific to preparing Clinger-Cohen Act economic analyses.
A13.2. Type Of Analysis Required.
A13.2.1. The Clinger-Cohen Act requires a Return on Investment calculation for automated
information systems. These systems can either be wholly automated information systems such
as a business system or they can be part of another weapon system or product such as software
inside an aircraft. See DoDI 5000.02 Table 1 Note 4 for the definition of automated
information systems. The Automated Information System category designation is determined
by the Component Acquisition Executive, as delegated by the Secretary of Defense or
Secretary of the Military Department, DoDI 5000.02.
A13.2.2. To satisfy Clinger-Cohen Act requirement, the Department of Defense requires an
Economic Analysis or a Life Cycle Cost Estimate depending on the type of system being
procured. The following rules apply. The rules are summarized in Figure A12.1
A13.2.2.1. Acquisition Master List or Other Acquisition Designation. Programs/systems
on the Acquisition Master List or with Other Acquisition Designation, (i.e., Middle-Tier
Acquisitions from FY17 NDAA Section 804) that acquire information technology require
Clinger-Cohen Act certification. If a program/system is not on the Acquisition Master List
or does not have an acquisition definition, then Clinger-Cohen Act requirements are
performed at the discretion of the Secretary of the Air Force- Chief Information Officer/A6.
A13.2.2.2. Acquisition Phase
A13.2.2.2.1. In general, an economic analysis or life cycle cost estimate is required for
Clinger-Cohen Act purposes during the development and production or deployment
acquisition phases.
A13.2.2.2.2. A program/system at any phase after the full deployment decision (or
equivalent) in its acquisition lifecycle is not required to update its economic analysis
or life cycle cost estimate for Clinger-Cohen Act purposes.
152 AFMAN65-506 6 SEPTEMBER 2019
A13.2.2.2.3. For Defense Business Systems, a system at any point after the acquisition
authority to proceed decision point (or equivalent) is not required to update its
economic analysis for Clinger-Cohen Act purposes.
A13.2.2.2.4. Modification programs to the parent program require an independent
economic analysis or Life Cycle Cost Estimate (LCCE) for Clinger-Cohen Act
purposes if that modification is treated as an acquisition program in its own right
regardless of the acquisition phase of the parent program.
A13.2.2.3. When the system program is on the acquisition master list or other acquisition
designation and at an acquisition phase which requires an economic analysis or life cycle
cost estimate for Clinger-Cohen Act purposes, the next key discriminators for determining
the type of analysis required are (1) whether the program/system is, or just includes, an
Automated Information System; (2) whether the program/system is a Defense Business
System; (3) whether the program/system is classified as a National Security System; and
(4) whether the program system is an information technology service. The type of analysis
required in each situation is described below:
A13.2.2.3.1. If the system under consideration is not an Automated Information
System under DoD Instruction 5000.02 Table 1 Note 4, then:
A13.2.2.3.1.1. A Life Cycle Cost Estimate is required for Clinger-Cohen Act
purposes unless the program is an Information Technology Services Contract.
A13.2.2.3.1.2. If a program is an Information Technology Service Contract, then
an Economic Analysis with a Return on Investment is required for Clinger-Cohen
Act purposes. Information Technology Services are defined in DoDI 5000.74.
A13.2.2.3.1.3. Note: The current definition in Table 1 Note 4 excludes “computer
resources, both hardware and software, that are an integral part of a weapon or
weapon system” from the definition of Automated Information Systems. However,
the analyst should always validate their official automated information system
categorization.
A13.2.2.3.2. If the system under consideration is a Defense Business System, then
perform an Economic Analysis with a Return on Investment when the system is in the
“Business System Functional Requirements and Acquisition Planning Phase”
(approaching it’s “Acquisition” Authority to Proceed) or equivalent phase. Defense
Business Systems are defined in DoDI 5000.75. By definition, the category of Defense
Business System does not include National Security Systems.
A13.2.2.3.3. If the program/system under consideration is an Automated Information
System, but not a National Security System and not a Defense Business System, then
perform an Economic Analysis with a Return on Investment.
A13.2.2.3.4. If the program/system under consideration is an Automated Information
System and also a National Security System, then the return on investment required for
Clinger-Cohen Act purposes will be met using an economic analysis with return on
investment if practicable; otherwise, a life cycle cost estimate is required. This is the
one categorization where an economic analysis is required, but a life cycle cost estimate
may be substituted if the economic analysis is not practicable to complete.
AFMAN65-506 6 SEPTEMBER 2019 153
A13.2.2.3.4.1. In determining whether an economic analysis would be practicable,
the analyst should consider whether it is possible to accomplish the return on
investment, which is essentially a quantitative calculation, and also whether the
return on investment would provide information that could be relevant to the
decision.
A13.2.2.3.4.2. The initial determination of whether an economic analysis is
practicable is made by the program office. (T-2). The final determination is made
by the highest level of Financial Management concurrence required for the analysis
(Economic Analysis or Life Cycle Cost Estimate). This will be either the Product
Center Cost Chief, the Sustainment Center Cost Chief, the MAJCOM Cost Chief,
or SAF/FMC and is determined by acquisition category level (see the coordination
process in paragraph A13.4 of this Attachment). (T-2). The program office may
consult with the appropriate center level Cost Chief or SAF/FMC in advance when
making an initial determination on whether an Economic Analysis is practicable.
A13.2.2.3.4.3. For acquisition programs, lack of time is rarely an acceptable reason
for determining that accomplishing an Economic Analysis is not possible.
Figure A13.1. Clinger-Cohen Act Economic Analysis and Life Cycle Cost Estimate
Requirements.
A13.3. Timing of The Requirement For An Economic Analysis Or Life Cycle Cost Estimate.
A13.3.1. For Defense Business Systems, the Economic Analysis is required for the
Acquisition Authority To Proceed decision point (or equivalent). Figure A13.2 shows the
timing of the Defense Business System Economic Analysis in the context of the Defense
Business System Acquisition Cycle described in DoDI 5000.75.
154 AFMAN65-506 6 SEPTEMBER 2019
Figure A13.2. Timing of Economic Analysis Requirement For Defense Business Systems.
A13.3.2. For non-Defense Business Systems Automated Information Systems requiring an
Economic Analysis, the Economic Analysis is required for Milestone A, B, C and Full Rate
Production/Full Deployment decisions (or equivalent). For Milestone A, an Analysis of
Alternatives can satisfy the requirement for the initial Economic Analysis as long as the
Analysis of Alternatives includes a rigorous consideration of costs and benefits associated with
alternative means of accomplishing the objective and a return on investment. Figure A13.3
illustrates the timing of the non-Defense Business Systems Economic Analysis in the context
of the Acquisition Cycle described in DoDI 5000.02.
Figure A13.3. Timing of Economic Analysis Requirement For Non-Defense Business
Systems.
A13.3.3. An Economic Analysis with an appropriate Return on Investment calculation from a
previous milestone decision may be sufficient for subsequent milestones if the Life Cycle Cost
Estimate has not changed by more than 15%, and the results of the Economic Analysis would
not be overturned by a change in cost or benefits.
A13.4. Coordination Process.
A13.4.1. If an Economic Analysis is required for Clinger-Cohen Act compliance, the
Economic Analysis will be developed by the Program Office and submitted to the appropriate
Cost Chief for concurrence and further reviews as required in paragraph A13.4.1.1 and
paragraph A13.4.1.2 (T-2). The coordination process is also summarized in Figure A13.4
AFMAN65-506 6 SEPTEMBER 2019 155
A13.4.1.1. For Defense Business Systems that are Category I, non-Defense Business
Systems that are ACAT I, and for select programs, as identified by the Secretary of Air
Force and/or Milestone Decision Authority, the Economic Analysis and associated
documentation (including coordination by the appropriate Cost Chief’s office) will be
submitted to Secretary of the Air Force/Financial Management Cost for review. (T-1).
A13.4.1.1.1. Programs on the Acquisition Master List or other Acquisition designation
will be approved by the appropriate Center Cost Chief prior to being submitted to
Secretary of the Air Force/Financial Management Cost. (T-1).
A13.4.1.1.2. Projects not on the Acquisition Master List or other Acquisition
designation will be approved by the appropriate MAJCOM Cost Chief prior to being
submitted to SAF/FMC. (T-2). For Non-Acquisition designated Clinger-Cohen
Projects with an investment (non-recurring) cost of under five million dollars the
MAJCOM Commander may delegate review/approval to the Wing-level Commander
who may further delegate approval to the Wing-level Comptroller for where the project
originated.
A13.4.1.1.3. The reviewing offices within the Secretary of the Air Force/Financial
Management Cost are SAF/FMC and AFCAA/FMCI. Once approved, Secretary of the
Air Force/Financial Management Cost & Economics will distribute approval
coordination to the appropriate MAJCOM Cost Office or Center Cost Office. Secretary
of the Air Force/Financial Management Cost & Economics coordination will serve as
evidence of Clinger-Cohen Act compliance of the return on investment requirement for
category I Defense Business Systems, non-Defense Business Systems that are ACAT
I, and select programs.
A13.4.1.2. For non-select Defense Business Systems that are category II and III, the
highest level of concurrence required is the Product Center Cost Chief, Sustainment Center
Cost Chief, or MAJCOM Cost Chief. (T-2). Similarly, for ACAT II and III systems that
are non-select and non-Defense Business Systems, the highest level of concurrence
required is the Product Center Cost Chief, Sustainment Center Cost Chief or MAJCOM
Cost Chief. (T-2). These cost offices’ coordination will serve as evidence of Clinger-
Cohen Act compliance for category II and III non-select programs.

Figure A13.4. Clinger-Cohen Act Element 6 Process Flow And Coordination
Requirements.
A13.5. Alternatives.
A13.5.1. When developing an Economic Analysis, the analyst should consider all reasonable
alternatives for meeting the objective of the project. In some cases, Congressional legislation
may exclude the status quo (current state) as an alternative. If so, the analyst should list the
status quo and explain why it is not a feasible alternative for further consideration. It is only
in this situation that an economic analysis with only one costed course of action is acceptable.
If the status quo is not excluded, then the Clinger-Cohen Act Economic Analysis will include
at least two possible alternatives (one alternative in addition to the status quo). (T-2). The
second alternative will be the planned system investment. (T-2).
A13.5.1.1. Alternative 1 (Current State) The course of action if the investment under
consideration is not made. Essentially, it is the current or “as-is” process prior to
investment.
A13.5.1.1.1. Software maintenance to keep software up-to-date should be included in
the Status Quo recurring cost.
A13.5.1.1.2. Software maintenance as defined by Defense Federal Acquisition
Regulation System Subpart 208.7401 is defined as the right to receive and use upgraded
versions of software, updates and revisions.
A13.5.1.2. Alternative 2 (Investment) The course of action if the investment under
consideration is made.
A13.5.1.3. It is important to note that the requirements/technology maturation process may
reveal multiple reasonable material solutions that would satisfy the objective. With more
than one reasonable material solution, there may be more than two alternatives in the
economic analysis.
AFMAN65-506 6 SEPTEMBER 2019 157
A13.6. The Return On Investment Calculation
A13.6.1. A Return on Investment, as commonly defined, is intended to measure financial gain
(after investment cost) as a percent of the investment cost. For the Air Force, this financial
gain commonly translates into budget savings. Using this definition, the Return on Investment
calculation requires estimating a status quo alternative from which the budget savings can be
calculated.
Table A13.1. Return On Investment Calculation.
Figure A13.5. Return on Investment.
A13.6.2. For programs where the status quo has been excluded as a feasible alternative, the
analyst may substitute “criteria related to a Return on Investment” instead of the formal Return
on Investment calculation described above. The analyst should include the costs of the
investment alternative(s) as the investment and a description of the (non-monetary) benefits
from the investment alternatives as the return.
A13.6.3. Many programs are undertaken to correct a deficiency unrelated to budget savings.
As a result, the Return on Investment may not be a meaningful measure of which alternative
best meets the needs of the Air Force. In such a case, while the analyst is still required to
include the Return on Investment by law, the benefit analysis should carry a greater
significance than the Return on Investment in the Economic Analysis.
Figure A13.6. Return on Investment Alternative.
158 AFMAN65-506 6 SEPTEMBER 2019
A13.7. Additional Considerations.
A13.7.1. If cost risk is included in the estimate for the “investment” alternative, cost risk
should also be assessed for the status quo alternative.
A13.7.2. Both alternatives should be evaluated at similar confidence levels.
AFMAN65-506 6 SEPTEMBER 2019 159
Attachment 14
OTHER SPECIALIZED ANALYSES
A14.1. Lease-Purchase Decisions
A14.1.1. OMB Circular A-94, Guidelines and Discount Rates for Benefit-Cost Analysis of
Federal Programs, distinguishes two types of decisions regarding lease-purchase:
A14.1.1.1. The decision to acquire the services of an asset. This involves cost-benefit
analysis to show that acquiring the asset is the best economic alternative.
A14.1.1.2. Once the decision to acquire the services of an asset is made, the related
decision to lease or purchase the asset. In this lease-purchase type of analysis, benefits are
often essentially the same. In many Air Force analyses, mission need has already
determined the requirement. In this situation, only a lease-purchase analysis would be
required (i.e., an economic analysis with two alternatives, lease and purchase).
A14.1.2. When estimating for major facilities, the Air Force normally does not have authority
to solicit bids both for a lease or service contract alternative and for a purchase alternative.
Under these circumstances, one estimation method is:
A14.1.2.1. Estimate a life-cycle flow of funds for the purchase alternative.
A14.1.2.2. Compare the present value (i.e., discounted dollars) of contractor bids for the
lease or service contract with the present value of the purchase alternative. IMPORTANT:
Work with contracting offices to develop such bids since it must be made clear that the
government's request for information may not lead to an offer.
A14.1.3. All economic analyses involving lease-purchase analysis follow special guidance
outlined below.
A14.1.3.1. Leases are often "level term." Their cost is set per month or year over a number
of months or years. The lease terms are stated in nominal (i.e., inflated) dollars. For this
reason, economic analyses involving lease-purchase analysis are often accomplished in
nominal dollars. Discount these nominal dollars using the nominal discount rate provided
in OMB Circular A-94, Appendix C, for the term of the lease. The rates are updated
annually when the President presents the Budget, and can be found on the SAF/FMC
SharePoint
®
page, to which a link is provided on the SAF/FMCE page of the Air Force
Portal, or on the OMB website.
A14.1.3.2. If lease costs are stated in constant dollars, use constant dollars in the
comparative analysis and discount at the real rate.
A14.1.3.3. When the term of a lease or service contract differs from the economic life of
the asset under the purchase option, estimate asset value at the end of the lease term and
include it in the purchase alternative as a benefit (negative cost) in the final period of the
analysis.
A14.1.3.4. Add to the cost estimate for the lease the cost to the Treasury of any special tax
benefits available to the lessor associated with a lease.
160 AFMAN65-506 6 SEPTEMBER 2019
A14.1.3.4.1. For example, if a particular leased asset enables a lessor to take advantage
of accelerated depreciation tax benefits, increase the contract bid to offset these losses
to the Treasury.
A14.1.3.4.2. Consider current tax laws applicable to a lessor to determine whether or
not an adjustment is appropriate in a particular comparative analysis. Because tax laws
change, consult with legal and contracting staff.
A14.1.3.4.3. In most accelerated depreciation schedules, the amount of the special tax
advantage is only the portion of the total allowance for depreciation in excess of
"normal" economic depreciation. In such cases, the calculation of normal economic
depreciation is an annual amount equaling acquisition price divided by economic life
(i.e., straight-line depreciation).
A14.2. Energy Projects.
A14.2.1. Since energy price changes in energy sectors are apt to differ from price changes in
other sectors, use Department of Energy (DoE) indices, published annually (NISTIR 85-3273-
xx).
A14.2.2. Use the following guidelines for Energy Resilience and Conservation Investment
Program (ECIP) comparative analyses of retrofits to existing energy systems:
A14.2.2.1. Base all analyses on an economic life of 25 years or the life of the retrofit or of
the facility, whichever is less.
A14.2.2.2. Use the Department of Energy published escalation rates for energy.
A14.2.2.3. Energy Resilience and Conservation Investment Program projects will use the
published discount rates in the annual supplement to National Institute of Science and
Technology (NIST) handbook 135, NISTIR 85-3273-xx, Energy Price Indices and
Discount Factors for Life-Cycle Cost Analysis (check with the civil engineering office).
(T-2).
A14.2.3. Analyze lease-purchase decisions and private sector financed leases or service
contracts involving energy projects using the following guidance:
A14.2.3.1. Use the Energy Resilience and Conservation Investment Program approved
discount rate for lease-purchase comparative analyses.
A14.2.3.2. Escalate the government MILCON Program alternative estimate using DoE
rates for comparison with private sector financed (e.g., lease, service contract) alternatives.
Take the lessor or contractor bid at face value (i.e., not escalated, since this constitutes the
actual commercial bid).
AFMAN65-506 6 SEPTEMBER 2019 161
A14.2.3.3. Energy Resilience and Conservation Investment Program projects should in
most cases have a Simple Payback of 10 years or less with a minimum Savings Investment
Ratio (SIR) of 1.25 to meet Department of Defense criteria. (Estimated Simple Payback
time is the number of years required for the cumulative value of energy cost savings less
future non-fuel costs to equal the investment costs of the building system without
consideration of future price changes or discount rates. For example, invest $100,000 at
an annual savings of $20,000. Simple Payback is investment divided by savings, so the
Simple Payback would be 5 years. Simple Payback does not take into account the time
value of money.)
A14.2.4. Analyze energy plant conversion projects using the following guidelines:
A14.2.4.1. Discount projects using a renewable energy source at the rate for Energy
Resilience and Conservation Investment Programs.
A14.2.4.2. Discount projects using fossil (nonrenewable) fuel at the rate published by the
OMB.
A14.2.4.3. Use DoE energy indexes.
A14.2.5. Additional analytical tools can be found at the Federal Energy Management
Program’s website: (https://www.energy.gov/eere/femp/femp-solution-center-tool-box)
Note: Comparative analyses which are not specifically energy projects are not required to use
Department of Energy indexes.
A14.3. Warranty Cost-Benefit Analysis.
A14.3.1. Follow this guidance when performing a cost-benefit analysis (CBA) to determine
whether using a warranty is beneficial to the government. (T-1). The principal criterion for
determining life cycle cost (LCC) advantage is the present value (i.e., discounted dollars) of
expected program costs and benefits, estimated both with warranty coverage and without
warranty coverage, and (if appropriate) with partial warranty coverage.
A14.3.2. Plan sufficient lead time to complete the detailed work required in a warranty CBA.
Start early if it will support contract negotiations. Interim CBA findings are very valuable in
establishing government negotiating positions; the CBA identifies expected major cost drivers
and potential failure nodes.
A14.3.2.1. The analyst may do the CBA as early as the demonstration and validation phase
and then update the CBA during full-scale development and source selection or
negotiations for the production contract. It is best to accomplish the CBA before release
of the Request for Proposal for the production contract and update after receipt of proposals
with the contractor's proposed warranty price.
A14.3.2.2. The OPR for life-cycle cost analysis of the program is OPR for the warranty
CBA, unless the program manager assigns responsibility elsewhere. The program manager
(Program Office (PO) director, project manager, etc.) should ensure the CBA is initiated
as soon as system technical design is well enough established to allow LCC estimation.
A14.3.2.3. OCRs are significant stakeholders and any other organizations with
information necessary to develop the life-cycle cost model. OCRs usually include civil
engineering and logistics staffs.
162 AFMAN65-506 6 SEPTEMBER 2019
A14.3.3. A computer model is available to do the CBA. Contact HQ Air Force Material
Command Financial Management (AFMC/FM) for information. Consider information in the
Warranty Activity Report, if available, when doing the CBA.
A14.3.4. Estimate LCC for the system or component without warranty coverage. Then
estimate LCC under full or partial warranty coverage.
A14.3.4.1. Break down the system or item under consideration into its constituent parts,
based on the expected major operating and support (O&S) cost drivers and associated
failure nodes. Items considered for warranty coverage may be a combination of new
components and of components similar to those in historically procured items. Therefore,
analysts may face a combination of historical data and engineering forecasts to identify
cost drivers and failure nodes.
A14.3.4.2. Estimate the expected costs over time for each failure node, based on expected
failures and anticipated cost per failure.
A14.3.4.2.1. Use statistical methods or mathematical models to relate failures at each
node to variables measuring system deployment and operation (e.g., shelf life,
operation cycles, hours of operation, or presence or absence of special operating
conditions).
A14.3.4.2.2. Estimate the mean time between failures (mean operating cycles between
failures, etc.) and variables which are related to failure.
A14.3.4.2.3. Build estimates of the cost of a failure at each node from historical data
or projections, as applicable.
A14.3.4.2.4. Sum up monetary LCCs as the total of the costs of each failure node.
A14.3.5. Estimate LCCs for the alternative including warranty coverage. The basic procedure
is the same as above: break down the system or item into its major cost components. This is
particularly useful for addressing whether proposed warranty provisions should be accepted.
A14.3.5.1. Estimate the costs and benefits of each warranty clause or provision.
A14.3.5.1.1. Consider benefits to the government of warranty implementation plans
and procedures.
A14.3.5.1.2. Consider administrative costs of the warranty and potential claims that
the warranty is likely to cover. When possible, identify administrative costs with
specific warranty provisions, to increase the precision of the warranty assessment.
A14.3.5.2. Consider warranty effects on system or item cost components or performance
characteristics outside warranty coverage. For example, consider such factors as the effects
of warranty provisions on system field performance or the implicit cost differences due to
different turnaround times between contractor and in-house repair.
AFMAN65-506 6 SEPTEMBER 2019 163
A14.4. Military Construction Design
A14.4.1. Purpose. This guidance establishes criteria and standards for performing
comparative analyses and life cycle cost studies used in support of design decisions for
MILCON program projects, i.e., to support the selection from various alternatives of
components/systems being considered as elements in facilities design. These criteria and
standards apply to all design decisions regardless of when they are made in the planning,
programming, design or procurement process. This guidance does not apply to economic
analyses and life cycle studies used to make project justification decisions during the planning
and programming process.
A14.4.2. General. Comparative analyses shall be conducted as part of the design process to
ensure the selection/rejection of design alternatives is not based solely on construction costs,
but also on the lowest life cycle costs (LCC), that is, lowest total cost of ownership. (T-2). The
depth and degree of formality of these analyses shall be determined on a case- by-case basis to
ensure that the potential benefit from information accruing from the analysis is commensurate
with the effort for the analysis. Results of generic studies or results of previous analyses of
alternatives similar to those currently under consideration may be used in lieu of performing a
new study provided the previous study was based on similar design conditions, criteria, and
methods. Previous studies should be updated as required to reflect changes of conditions
significant enough to impact the design decision. All comparative analyses and other
justification for the selection of a design alternative, whether a previous study or a new one,
shall be clearly documented in the appropriate section of the project design analysis. (T-2).
A14.4.3. Methods. All analyses shall consider the total LCC for design alternatives, where
the LCC includes all costs and revenue associated with an alternative over its expected life,
including but not limited to construction/acquisition, energy, maintenance, operation, repair,
replacement, alteration, disposal costs, and retention values. (T-2). The present value
discounting approach shall be used to adjust for the differences in timing of cost and benefits
unless otherwise specified by other directives or by public law. (T-2). Discounting should be
applied to all cost and benefits over the appropriate analysis period. Specific criteria are as
follows:
A14.4.3.1. Energy Related Studies. All energy related economic studies (in which
energy costs are relevant, regardless of their magnitude relative to other costs) shall use the
current discount rate published by the National Institute of Standards and Technology
(NIST) in their annual supplement to NIST Handbook 135, and disseminated by the
appropriate Service Headquarters Office. (T-2).
A14.4.3.2. Non-energy Related Studies. All economic studies other than energy related
economic studies shall use the current discount rates published annually by the OMB as
Appendix C to OMB Circular A-94, and disseminated by the SAF/FMC. (T-2).
A14.4.3.3. Analysis Period. When using Terminal Value, the analysis period shall be
the life expectancy of the alternative with the shortest life. (T-2). When using Uniform
Annual Cost, the period of analysis will match the life expectancy of the facility in each
alternative. (T-2). Note: An adequate cost analysis of a utility system should be over a
term greater than 25 years. Generally, design lives of Electrical, Natural Gas, Water, and
Wastewater systems are a minimum of 50 years. LCCs over a shorter term tend to be very
inaccurate
164 AFMAN65-506 6 SEPTEMBER 2019
A14.4.3.4. Cash Flow. In general, cash flow used in the analysis will be based on the
estimated calendar dates on which the events and cost/benefits are projected/scheduled to
occur. Construction/acquisition costs may be assumed to be incurred as a single lump sum,
preferably at the time corresponding to the midpoint of the construction/acquisition
process. Other cash flows that occur periodically throughout the year (e.g., cost of fuel,
electricity, water, maintenance) may be assumed to be incurred as a single lump sum,
preferably at midyear. In circumstances where the above assumptions add unnecessarily to
the complexity of the calculations, all cash flows may be assumed to occur at the end of
the year in which they are actually scheduled/projected to occur.
A14.4.3.5. Costs. As a minimum, costs will be reported in present value terms. (T-2).
Otherwise, costs must be clearly labeled as to the year and type of dollar. In projecting
future costs, an allowance for future price-level changes, (i.e., escalation), will be made for
costs expected to change at rates higher or lower than the general rate of inflation. For
energy studies, fuel/energy costs shall use escalation rates as published by NIST in
Handbook 135. (T-2).
A14.5. Program Evaluation:
A14.5.1. A Program Evaluation is an economic analysis of on-going operations to ensure
established goals and objectives are being attained in the most cost-effective manner. A
program evaluation compares actual performance with stated program objectives. A program
evaluation must be performed when directed by the program’s leadership or higher authority,
or when prescribed by functional directives. (T-2).
A14.5.2. Responsibilities Assigned. The official who implements a program, or a higher
authority, directs that a program evaluation be completed at a specific future date. The
functional manager, with the assistance of the financial management staff, then establishes a
plan to collect and maintain the cost and benefit data necessary for the evaluation.
A14.5.3. General Program Evaluation Procedures when preparing a program evaluation
comparative analysis:
A14.5.3.1. Set reference points (baselines, milestones, and goals) for the analysis as soon
as possible.
A14.5.3.2. Determine if an analysis supporting previous decisions is available. Previous
comparative analyses may help start the process of analyzing the program or operation's
goals, assumptions, alternatives, costs and benefits, outputs, or effectiveness. However,
avoid excessive reliance on a previous analysis when the situation or contributing variables
have changed.
A14.5.3.3. Identify performance measures from the program or operation. It may be
helpful to compare performance measures with related on-going programs.
A14.5.3.4. Performance measures are inherently quantitative. If adequate data does not
exist for measuring performance, work with experts to determine adequate measures and
begin accumulating such data. The data must be auditable and reflect significant
organizational missions and functions, satisfaction of customer needs, timely
accomplishment of processes, relevant environmental impacts, or resources consumed or
required.
AFMAN65-506 6 SEPTEMBER 2019 165
A14.5.3.5. Identify and discuss important qualitative benefits (e.g., improvements in
process quality, mission fulfillment, health, safety, morale, security factors).
A14.5.3.6. Whenever trends are significantly different from previous estimates, examine
specific reasons for the variance.
A14.5.4. Methodology. The following step-by-step procedure can be used to facilitate output
measurement.
A14.5.4.1. Step I - Identify All Relevant Outputs. Government programs/projects have at
least one and often two or more objectives. These objectives may be prescribed by law,
established by policy or may be based on historical practice. There should be a causative
relationship between activities, as measured by the output indicator and the resources
consumed (costs). A restatement of resources consumed is not a good way to measure
output. For example, a statement of the man-hours required to do a job is simply another
way of accounting for resources consumed and tells little about what is accomplished. The
difference between costs of competing alternatives, i.e., differential costs or costs savings,
is not an "output" for purposes of program evaluation.
A14.5.4.2. Step II - Establish Data Sources. Avoid generating unnecessary work by
determining if adequate information is already available in some form. Consider sources
such as: established reports, opinions and judgments of experts, observations and
tabulations of steps in work process, outside organizations and information centers.
A14.5.4.3. Step III - Collect, Summarize, Evaluate, Validate and Display or Present
Output Data. Select a technique for summarizing the data in a tabular, graphic or other
format as appropriate. The analyst has discretion in deciding the method employed and
techniques.
A14.5.4.4. Step IV - Compare Output Data with Resources Consumed. In the analysis,
identify the output and costs associated with a particular alternative or activity. If
practicable, construct graphic relationships of output to cost to observe trends developing
or to detect evidence of possible substandard performance. When output data are not
quantitative, the analysis is more difficult. In such cases, identify project outputs in precise
terms and compare the outputs to the required resources so that the decision-maker can
determine the most reasonable course of action.
A14.6. Product Support Business Case Analysis:
A14.6.1. A Business Case Analysis is a statutory requirement for all major weapon systems
based on Title 10, United States Code (USC) Section 2337. DoDI 5000.02, Operation of the
Defense Acquisition System states the Business Case Analysis will be included as an annex to
the Life Cycle Sustainment Plan. (T-0).
A14.6.2. Product Support Business Case Analyses must comply with the guidance in this
manual. See Air Force Pamphlet 63-123, Product Support Business Case Analysis, for
additional guidance on preparing a Product Support Business Case Analysis.
A14.6.3. The Product Support Business Case Analyses for Acquisition Category 1, Defense
Business Systems Category I and select programs are approved at the SAF/FMC Level.
Category II and III are approved at the MAJCOM or Center Level.
166 AFMAN65-506 6 SEPTEMBER 2019
A14.7. Foreign Currency Conversion:
A14.7.1. This section provides additional guidance on and examples of foreign currency
conversions. The guidance in this Attachment addresses, in turn, constant and nominal dollar
analysis. The guidance assumes the analyst has collected some costs expressed in foreign
currency.
A14.7.2. Constant Dollar Analysis. Obtain a forecast of the exchange rate for the FY which
will be the base year of the analysis (i.e., the first year in which there will be differences in
expenditures for different alternatives). Use the exchange rate for that base year of the analysis
to convert expenditures in every year. The resulting dollars are constant dollars of that base
year, resulting in a constant dollar analysis. Note: Exchange rates are ordinarily cited on the
basis of national currency unit per US dollar (e.g., Yen per dollar). An exception is often the
British Pound Sterling, which frequently is cited as dollars per pound. Check the source for the
basis of the rate.
A14.7.3. Nominal Dollar Analysis. Obtain a forecast of the exchange rate for each year of the
analysis. Convert each year's foreign currency expenditures into dollars using the forecast
exchange rate for each year. The resulting dollars are nominal dollars. If the forecast does not
cover all the years in the analysis, use the exchange rate for the last year forecast for all
remaining years. An alternate approach: use the exchange rate for the first year of the analysis
to convert foreign currency into US dollars; then use a US inflation rate forecast to convert
these constant dollars into nominal dollars.
