Planning, Programming, Budgeting, and Execution in Comparative Organizations

The U.S. Department of Defense (DoD) Planning, Programming, Budgeting, and Execution (PPBE) System is a key enabler for DoD to fulfill its mission. But in light of a dynamic threat environment, increasingly capable adversaries, and rapid technological changes, there has been increasing concern that DoD's resource planning processes are too slow and inflexible to meet warfighter needs. As a result, Congress mandated the formation of a legislative commission to (1) examine the effectiveness of the PPBE process and adjacent DoD practices, particularly with respect to defense modernization; (2) consider potential alternatives to these processes and practices to maximize DoD's ability to respond in a timely manner to current and future threats; and (3) make legislative and policy recommendations to improve such processes and practices for the purposes of fielding the operational capabilities necessary to outpace near-peer competitors, providing data and analytical insight, and supporting an integrated budget that is aligned with strategic defense objectives. The Commission on PPBE Reform asked the RAND Corporation to provide an independent analysis of PPBE-like functions in selected countries and other non-DoD federal agencies. This report, part of a four-volume set, presents case studies of PPBE functions in the U.S. Department of Homeland Security (DHS), the U.S. Department of Health and Human Services, the National Aeronautics and Space Administration, and the Office of the Director of National Intelligence (ODNI) to provide insights for improving DoD's PPBE processes.
