The Defense Acquisition Guidebook (DAG) has been retired and replaced by a modern set of guidebooks aligned with our new acquisition policies that provide the acquisition workforce with discretionary best practices that should be tailored to the needs of each program. Acquisition professionals should use these guidebooks as a reference source supporting their management responsibilities.
The T&E Enterprise Guidebook further clarifies and details the procedures that should be implemented to meet the intent of the T&E policies outlined in DOD Instruction (DoDI) 5000.89.
