Summary

The Under Secretary of Defense for Acquisition and Sustainment must manage the defense acquisition system under the Secretary of Defense. They must control the system and carry out whatever duties are needed to meet the system’s goals, including duties assigned elsewhere in law. Each military department’s service acquisition executive must run the parts of the acquisition system for that department, following the Under Secretary on acquisition matters and the military secretary for department control. Their duties include using fast, user-validated strategies; using data to balance life-cycle cost, schedules, performance, technical feasibility, and quantities for best value; running short develop-test cycles and ending efforts that stray from priorities or greatly exceed cost or schedule limits; notifying the Joint Requirements Oversight Council within 30 days of any program change that materially alters requirements, quantities, or delivery dates; filling critical acquisition positions (see section 1731) with trained people; and promoting clear cooperation with private companies to deliver safe, effective systems on schedule and on cost baselines.
