Defense Primer: Planning, Programming, Budgeting, and

Execution (PPBE) Process


Introduct on
The Planning, Programming, Budgeting, and Execution
(PPBE) process is a U.S. Department of Defense (DOD)
system for allocating resources among the military
departments, defense agencies, and other entities (referred
to as DOD components). This annual process serves as the
framework for DOD  civilian and military leaders to decide
which programs and force management requirements to
fund based on strategic objectives. DOD Directive 7045.14
states the objective of the process is to provide the DOD
with the most effective mix of forces, equipment,
manpower,  and support attainable within fiscal constraints.
Chairman of the Joint Chiefs of Staff Instruction 3100.01F
describes the process as the Secretary of Defense's
institutional strategic planning system and the primary
decision-making process for translating strategic guidance
into resource allocation decisions. The process produces
DOD's  portion of the President's annual budget request to
Congress and updates the DOD's five-year funding plan,
known  as the Future Years Defense Program (FYDP). In
2024, the Commission on Planning, Programming,
Budgeting, and Execution Reform recommended replacing
PPBE  with a new Defense Resourcing System (DRS) to
strengthen the connection between strategy and resource
allocation while creating a more flexible and agile
execution process.

Background
In 1961, then-Secretary of Defense (SECDEF) Robert S.
McNamara   established the Planning, Programming, and
Budgeting System (PPBS) as a framework for linking
strategic objectives with resources. In 2003, DOD renamed
the system PPBE in part to emphasize the need to better
manage  the execution of budget authority provided by
Congress. The Deputy Secretary of Defense manages the
overall process. PPBE is one of DOD's three main
acquisition-related decision support systems, along with the
Joint Capabilities Integration and Development System
(JCIDS) for developing requirements to address capability
gaps and the Defense Acquisition System (DAS) for
managing acquisition programs. PPBE is a calendar-driven
process that, for any fiscal year cycle, typically begins more
than two years before the expected year of budget
execution. Figure 1 shows when PPBE actions associated
with a fiscal year cycle may occur during a calendar year.

PPBE PhaseS
The PPBE  process typically produces internal documents
and materials for each phase. The planning phase produces
the Defense Planning Guidance (DPG), which details force
development priorities. The programming phase generates a
Program Objective Memorandum   (POM), a funding plan
for each component covering a five-year period that adjusts


programs in the FYDP. The budgeting phase results in a
Budget Estimate Submission (BES), which covers the first
year of the POM and converts programs into budget terms
for submission to Congress.

Planning
The Under Secretary of Defense (USD) for Policy leads the
planning phase. The Chairman of the Joint Chiefs of Staff
(CJCS) also plays a significant role in the process, in
accordance with statutory responsibilities under 10 U.S.C.
§151 as the principal military advisor to the SECDEF. The
CJCS's role is, in part, to advocate for solutions to
department-wide requirements. The phase involves
reviewing the President's National Security Strategy, the
SECDEF's  National Defense Strategy, and the CJCS's
National Military Strategy to align the resulting Defense
Planning Guidance (DPG) with a presidential
administration's policy goals and views on potential threats,
force structure, readiness posture, and other factors.
Developed with input from the CJCS, military departments,
and combatant commanders, the DPG typically contains
guidance on investments and divestments for the
components and is intended to inform a component's POM.

Programming
The programming  phase is meant to analyze anticipated
effects of present-day decisions on the future force. The
Director of the Office of Cost Assessment and Program
Evaluation (CAPE) leads this phase. The programming
phase involves the head of each component developing a
POM  recommending  resource requirements over five years.
