After examining the OSD "Engineering of Defense Systems Guidebook" - it is lacking details for critical Systems Engineering processes like CBRN, OSS&E, Survivability, etc.
Is there a reason for removing just the Systems Engineering section of the DAG - while the other sections remain?
The DAG is in the process of being retired. Eventually all Chapters will have replacement guidebooks.
Unfortunately, the Human Systems Integration portion of the old DoDI 5000.02T has not yet been released as a separate DoDI.
Until the new DoDI is released, you can continue to refer to:
* Department of Defense Instruction (DoDI) 5000.02T, Operation of the Defense Acquisition System Enclosure 7, Human Systems Integration
* Defense Acquisition Guidebook Chapter 5, Manpower Planning and Human Systems Integration
* Defense Acquisition Guidebook CH 3-4.3.10, Human Systems Integration
