The Defense Acquisition Guidebook (DAG) Chapter 4, Systems Engineering is the primary reference on the use of systems engineering throughout the system life cycle. With this release, the chapter has been restructured to provide Program Managers and Systems Engineers with life cycle phase and systems engineering technical review expectations, including a knowledge-based, technical-maturity table for key events. The update reflects recent policy changes and Better Buying Power initiatives and emphasizes the role of systems engineering in providing balanced solutions (managing the system’s cost, schedule, performance, and risk) to deliver Warfighter capability needs.
