What is typically evaluated during the PPBS planning phase by the Joint Chiefs of Staff and CINCs?

During the Planning, Programming, Budgeting, and Execution System (PPBES) planning phase, the Joint Chiefs of Staff and Combatant Commanders (CINCs) assess extensive input to and reviews of every product and step in the process. This includes evaluating the Defense Planning Guidance (DPG), which lays the groundwork for future defense initiatives, programmatic priorities, and budget allocations.

The focus on thorough review and input is essential to ensure that military operations align with strategic goals and allocated resources effectively. In this context, every aspect of the planning process is scrutinized, from the initial concepts to specific programs designed to achieve defense objectives.

Other options, while potentially relevant to broader defense management, do not specifically capture the comprehensive nature of evaluation that occurs during the planning phase. For instance, focusing solely on past projects or civilian budgets would not fully encapsulate the necessity of aligning current strategic aims with the detailed planning dynamics necessary at this stage.
