Analysis of Alternatives

The Analysis of Alternatives (AoA) in the United States is a requirement of military acquisition policy, as controlled by the Office of Management and Budget (OMB) and the United States Department of Defense (DoD). It ensures that at least three feasible alternatives are analyzed prior to making costly investment decisions. The AoA establishes and benchmarks metrics for Cost, Schedule, Performance (CSP) and Risk (CSPR) depending on military "needs" derived from the Joint Capabilities Integration Development System process. It moves away from employing a single acquisition source to the exploration of multiple alternatives so agencies have a basis for funding the best possible projects in a rational, defensible manner considering risk and uncertainty.

The AoA assesses critical technology elements (CTEs) associated with each proposed material solution, identified in the Initial Capabilities Document (ICD), including; technology maturity, integration risk, manufacturing feasibility, and, where necessary, technology maturation and demonstration needs. An AoA begins by establishing or modifying Key Performance Parameters (KPPs) metrics for each alternative. these metric help compare the operational effectiveness, suitability, and life cycle costs of alternatives to satisfy the military need.

DoD Instruction 5000.02 requires an AoA in support of each decision milestone: The Milestone Decision Authority (MDA) directs a study team to accomplish the AoA; the AoA then becomes the primary input to the documents for development of a weapons acquisition program. The results of the analysis provide the basis for the Technology Development Strategy (TDS), which must be approved by the MDA at program's Milestone A.^† The AoA is executed before any solution is determined, and is updated throughout the life of the program.

The AoA attempts to arrive at the best value for a set of proposals received from the private sector or other sources. Though Source Selection criteria change per proposal request, and specifics are considered sensitive information, there is usually some form of the Cost Schedule Performance (CSP) trade-space analysis, and strong consideration of Risk, (CSPR). Performance is measured by n terms of Measures of Effectiveness (MOEs), and new capabilities. Risk is analyzed in many ways; aggressiveness of the schedule, cost reasonableness and finally, each MOE and capability may carry an associated risk.
