Is Planning, Programming, Budgeting, and Execution (PPBE) a calendar-driven process used for securing funding for major acquisition programs?

Planning, Programming, Budgeting, and Execution (PPBE) is indeed a calendar-driven process essential for securing funding for major acquisition programs within the Department of Defense. This systematic approach is designed to align defense resources with strategic priorities and ensures that funding is allocated effectively throughout the fiscal year. The process operates on a set timeline that includes phases for planning and programming, allowing for adjustments based on program requirements and budgetary constraints.

With a structured cycle, the PPBE process supports not only the identification and justification for funding needs but also the execution of budgets and tracking of expenditures. This structured approach is key to developing a disciplined method for achieving defense objectives, which further emphasizes why the statement is true.
