  1. Step 7: Comparison of Alternatives 7a. Compare COAs using alternative selection criteria to identify the preferred COA. 7b. If there is a bill associated with the recommended COA, identify the billpayer. 7c. Identify the positive and negative impacts of the second- and third-order effects. What must be done to manage the negative impacts? 7d. Determine the robustness of the conclusions. If anything changes – assumptions, costs, benefits, etc. – would the recommendation change? 7e. Identify the high-risk aspects of the recommended COA and define appropriate risk mitigation measures.

  2. Heart of Comparative Analysis • The essence of the CBA process is in comparing two or more courses of action in order to identify the preferred alternative. • As a general rule, the preferred alternative is the alternative that provides the greatest amount of benefit in relation to its cost (Best Value!). • Value = Benefit – Costs CBA is Value Analysis UNCLASSIFIED

  3. Aid for Completing Step 7a UNCLASSIFIED

  4. Best Practices • For most comparative analyses delta costs are more informative • Present the single (or two) most important benefit(s) to compare against cost • Find the “knee in the curve” or optimal value solution UNCLASSIFIED

  5. Common Mistakes • Assuming away the problem • Assuming away cost • “Over-averaging” for sake of simplification • Show examples of each (or at least last one) UNCLASSIFIED

  6. Simple Case Which COA is the best value? UNCLASSIFIED

  7. Data Analysis • Data in and of itself is of little use. • Analysis takes data and puts it into a format that enables us to make better decisions. UNCLASSIFIED

  8. Optimization Fairly linear relationship Increasing bang for buck Decreasing bang for buck Which COA is the best value? UNCLASSIFIED

  9. Optimization example • Find the “knee in the curve” • Simple linear example • use simplex • Teach solver • Efficient frontier? – or complex example UNCLASSIFIED

  10. Normalization of Value • Facilitates easy value comparison of COAs • Allows comparison of cost today to cost tomorrow • Allows comparison of present and future benefits • Allows comparison of costs and benefits • Appropriate method must be chosen from many choices • Costs and benefits may have to be recalculated based upon chosen method UNCLASSIFIED

  11. (Net) Present Value • The difference between the present value of cash inflows and the present value of cash outflows. • Used to analyze the profitability of an investment • Costs (outflows) and benefits (inflows)are in dollars • Value presented as a single number • Only works if costs and benefits are monetary UNCLASSIFIED

  12. PV Merits Pros • Most fundamental analysis • Very easy to compare results • Incorporates discount rate which can be represent risk Cons • Limited use in the Army • Benefits are purely monetary • Discount rate application can be difficult UNCLASSIFIED

  13. Example • Which costs more? • Present costs in base year. • Present costs in present value or NPV. Current/Then year $MM Inflation 3% Discount Rate 5% UNCLASSIFIED

  14. PV Example • Which costs more? Current/Then year $MM Constant/Base year $MM PV $MM discounted at 5% rate UNCLASSIFIED

  15. PV Example • Relative costs • Compare annual savings • Discounts at cost of capital Current/Then year $MM NPV $MM discounted at 5% rate UNCLASSIFIED

  16. Benefit/Cost Ratio • Easy to compare different alternatives • Total benefit obtained per unit of cost • Projects with greater BCRs are usually given priority over those with smaller BCRs • Alternatives that have a BCR greater than one (1) are considered viable UNCLASSIFIED

  17. BCR Examples • Simplified example with dollars • Operational example • Utility/dollar • Dollars/kill UNCLASSIFIED

  18. Decision Matrix • Tool compares benefits and costs to produce a single value score • Army staff officers taught to include in decision briefs UNCLASSIFIED

  19. Decision Matrix Merits Pros • Easy to use • Normalizes costs and benefits • Familiar tool Cons • Easy to introduce error • Highly judgmental • Discourages accurate identification of value • Easy to argue against results • Scoring is difficult UNCLASSIFIED

  20. Extraneous Data • Cost Drivers capture the primary costs of a proposal • Given a list of benefits, is there a primary consideration? • Focusing on a long list can distract decision makers from true impacts UNCLASSIFIED

  21. Example • Benefits: • Increased transaction rate • Better working area • Faster email processing • Less administrative burden • How do you present the value? UNCLASSIFIED

  22. “Cost Free” Analysis • Alternatives present savings against the status quo or baseline case • Or the analysis costs are non-monetary UNCLASSIFIED

  23. “Free” Example • Problem: After a Congressional inquiry, G-3/5/7 proposes formation of a new organization to track and coordinate MRAP related issues similar to DAMO-AV, meets 10 new requirements, I to X. • Status Quo: No new office, requirements I - V currently met by AMC and TACOM. • COA 1: Fill organization with 23 Military and Civilian personnel by eliminating current AMC MRAP office of 30. • COA 2: Fill organization with 23 Military and Civilian TACOM personnel. UNCLASSIFIED

  24. “Free” Example UNCLASSIFIED

  25. Double Counting of Criteria Move to criteria Impact of using personnel is counted both as a cost and a contra-benefit UNCLASSIFIED

  26. Step 7b: Billpayers • Billpayers are the funding sources that have been identified to cover the cost of the recommended COA. • In most cases, the individual or team developing the CBA won’t have the authority to identify billpayers. This requires collaboration with the organization’s resource manager and prioritizer. • Savings can be used as a billpayer, but cost avoidances cannot. • Savings: A cost reduction that enables a manager to move funds from one function to another • Cost avoidance: A cost reduction that does not enable a manager to move funds. Move to criteria (affordability) UNCLASSIFIED CBA Training Slides

  27. Step 7c: 2nd- and 3rd-Order Effects • Second- and third-order effects are the “ripple effect” of the recommended COA: “The recommended COA will solve our problem, but it will also create an additional factor we will have to deal with.” • The cost of many CBAs is purely a 2nd or 3rd order effect (e.g. policy change). • The scope or domain often limit the # of next order effects. Move to criteria (affordability) UNCLASSIFIED CBA Training Slides

  28. Risk Assessment • Risk assessment describes risks that can impact the achievement of stated benefits or the cost of solving the business problem. For each risk, assess the likelihood of occurrence and develop a mitigation strategy. • Ways to incorporate risk into value calculation: • Sensitivity analysis • Discount factors UNCLASSIFIED CBA Training Slides

  29. Sensitivity Analysis • Sensitivity analysis identifies the impact on the recommendation should any element of the analysis change. • Sensitivity analysis is a good means to address risk impacts UNCLASSIFIED CBA Training Slides

  30. Example • Variations in assumptions that change cost and benefits • @risk or crystal ball run • Change costs • change benefits • Change decmat weights UNCLASSIFIED

  31. Questions for Steps 7d and 7e • How sensitive is the recommendation to possible changes in costs, benefits, assumptions, etc? If the recommendation is highly sensitive to changes, has more in-depth analysis been done? • Which elements of the CBA require sensitivity analysis? • Test only those elements for which there is considerable uncertainty or risk. • Can include any element: Assumptions, constraints, costs, benefits, weighting of selection criteria, etc. • Address sensitivity from either or both perspectives: • What is the impact of a change of such and such a magnitude? • How large a change can occur before the recommendation changes? • Have all reasonably likely risks and their impacts been identified? Are the recommended mitigation approaches adequate? Are they affordable? UNCLASSIFIED

  32. Step 8: Report Results and Recommendations • Preferred format for documenting the CBA is a narrative. This will probably be accompanied by a decision briefing. • Results and recommendations summarize the analysis and make conclusive statements about the comparisons of alternatives. • The results address how the alternatives were ranked using the criteria developed in Step 6. Following a clear statement of the conclusions, there should be a firm recommendation regarding the preferred alternative. • All data and other information used in Steps 1-8 must be adequately documented. Supporting information should be identified so decision makers and analysts can understand how Steps 1-8 were developed. • Questions for the reviewer: • Does the package contain all key elements, accompanied by supporting documentation? • Does the recommended COA address the problem, and is it consistent with the assumptions and constraints? • Does the analysis explain how the recommended COA is best at satisfying the selection criteria?

  33. Practice Step 8 • We will discuss Step 8 by reviewing a notional CBA decision briefing for the APS practical exerciseNote: The CBA Guide, available at the Cost & Performance Portal, includes a narrative report for the APS example. Decision package must present a strong value proposition. That is, it must clearly show that the benefits of the recommended COA more than justify the costs and risks. UNCLASSIFIED
