An analysis of alternatives can be applied to anything—from a large military acquisition decision to a decision between two products.

An analysis of alternatives is an analytical comparison of the operational effectiveness, cost, and risks of proposed materiel solutions to gaps and shortfalls in operational capability. Such analyses document the rationale for identifying/recommending a preferred solution or solutions to the identified shortfall. Threat changes, deficiencies, obsolescence of existing systems, or advances in technology can trigger an analysis of alternatives.
