Reform of the Planning,Programming, Budgeting System,and Management Control in the U.S. Department of Defense: Insights from Budget Theory

Resource decision making for the Department of Defense (DOD) is one of the most challenging tasks in all of public financial management. DOD coordinates national security threat assessment, long‐ and intermediate‐range planning and programming with annual budget formulation and execution. Between 2001 and 2004, Defense Secretary Donald Rumsfeld changed the system significantly, simplifying, and synchronizing it with presidential terms of office. We assess Planning, Programming, Budgeting System (PPBS) reform through application of applied budget theory. We review system evolution, document recent reforms, explain why change was necessary, and assess implementation feasibility. Only preliminary evaluation is possible because change implementation will require five or more years.
