Summary

The Secretary of Defense must pick a senior official in the Office of the Secretary of Defense to run and watch over performance reviews and root cause studies for major defense acquisition programs. That person must not be in charge of running any of the programs. The Secretary must give that person the staff and resources needed, and make sure other DoD experts help when needed. The senior official must do periodic performance reviews or do them when asked by top leaders. The official must do root cause studies when required by section 4376(a)(1) or when leaders ask. The official must write rules and guidance for the military departments and Defense Agencies, check how useful the cost, schedule, and performance measures are and suggest improvements, and advise acquisition leaders before certifications under sections 4376 and 4377, before full-rate production, or before asking for multiyear procurement approval. A performance assessment looks at cost, schedule, and performance against current goals and whether the program will deliver useful capability on time and at good value. A root cause analysis finds why cost, schedule, or performance fell short, including things like unrealistic expectations or baselines, immature technology or high manufacturing risk, unexpected engineering or integration problems, changes in quantities, unstable or inadequate funding, poor government or contractor performance, or other causes.
