The Engineering of Defense Systems Guidebook and Systems Engineering Guidebook replace Chapter 3, Systems Engineering, of the Defense Acquisition Guidebook. The Engineering of Defense Systems Guidebook describes the activities, processes, and practices involved in the development of DoD systems. The guidebook aligns with the engineering disciplines covered in DoD Instruction 5000.88, Engineering of Defense Systems, and focuses on recommended engineering best practices for the DoD Adaptive Acquisition Framework acquisition pathways.

The Systems Engineering Guidebook provides systems engineering guidance and recommended best practices for defense acquisition programs. It is intended for Program Managers and Systems Engineers and may be tailored for programs in any of the DoD Adaptive Acquisition Framework pathways (DoD Instruction 5000.02). Programs can use the guidebook, along with other acquisition business resources, to plan and execute program systems engineering activities across the system life cycle.
