The Commission on Planning, Programming, Budgeting, and Execution (PPBE) Reform asked the RAND Corporation for an independent analysis of PPBE-like functions in selected countries and non-Department of Defense federal agencies. This executive summary distills key insights from nine case studies of budgeting processes across comparative organizations, as detailed in three companion volumes.

Policy and U.S. Intelligence Community (IC) professionals have suggested that the IC is held in increasingly lower regard by some decisionmakers and that predictions have had variable success in influencing decisionmakers. Researchers explored whether and to what degree trust in intelligence predictions and national estimates has degraded over time and what factors might have driven any changes in the relationship between policymakers and the IC.

This report, part of a four-volume set, presents case studies of planning, programming, budgeting, and execution (PPBE) functions in the U.S. Department of Homeland Security, the U.S. Department of Health and Human Services, the National Aeronautics and Space Administration, and the Office of the Director of National Intelligence to provide insights for improving the U.S. Department of Defense's PPBE processes.
