The approved budget, and whether the funds are

The Planning, Programming, Budgeting, and
Execution (PPBE) is one of three decision support systems for defense
acquisition, two others are Joint Capabilities Integration and Development
System, and the Defense Acquisition System.  We just talk about PPBE today. Planning phase includes information collection,
technologies and trends analysis, current and future capabilities needed to meet requirements
identification.  Programming phase review objectives and current
policy, assess infrastructure shortfalls, validates capability requirements, aligns
available resources, and evaluate various
tradeoff options, balance
and integrate resources according priorities, generates a Program Decision Memorandum.  Budgeting phase applies resources into an
appropriations account structure, ensure appropriate funding and fiscal
controls, ensure efficient use of
resources, and whether it
is realistic in the requested budget year. Execution phase creates Monthly
Phasing Plan, manages appropriated
funds to accomplish designed tasks, conducts continuous reviews, to determine
whether the appropriated funds are being obligated and expended in accordance
with the approved budget, and whether the funds are achieving the desired
effect (Performance and Accountability Report).

The project’s life cycle include
four phases: Project initiation, Concept Exploration, demonstration/validation,
full scale development. Four phases have common concerns, such as manning, technical
data, engineering services, facilities, etc. We can use entire PPBE as a tool
in each phase of the project’s life cycle, to ensure resources efficiency. We
also can use PPBE as a consistent framework to match
the project’s life cycle.  In
the project’s initial phase, PPBE
Planning can defines “What” needs to complete, provide
an outline of the project.  In the concept exploration phase,
PPBE Programming work out on the “How” to approach the goals, identify stake holders, define the working processes and work breakdown structure.  In the demonstration/validation phase, we make
sure the project is “ON TRACK”, PPBE Budgeting provides the “Why”, and results
in a complete budgetary request, finally enact appropriations. In the full scale
development phase, PPBE Execution ensure that team members meet designed goal and
timeline for tasks, tracking spending, manage assets and resources, to maintain
the project on track.
