PMAs establish achievable and measurable annual plans that are fully resourced and reflect the approved program. PMAs must be prepared for Acquisition Category (ACAT) I and II programs after DoD makes the investment decision to pursue a new program and the program manager (PM) has been assigned. The PM, the component acquisition executive (CAE), and the requirements and, where applicable, resource authorities sign the agreement. PMAs are updated annually or more frequently if the conditions that formed the basis for the agreement (e.g., requirements, funding, or execution plans) have changed.
