After nearly 20 years of service to the defense acquisition workforce through multiple iterations over the last two decades, the venerable Defense Acquisition Guidebook (DAG) has officially been retired. According to an announcement on the Adaptive Acquisition Framework (AAF) “Acquisition Guidebooks & References” website, “the Defense Acquisition Guidebook has been retired and replaced by a modern set of guidebooks aligned with our new acquisition policies. Identified below are twelve different functional areas fundamental to the operation of the defense acquisition process. Click on them to access specific guidebooks and where available, additional relevant reference materials”

For the life cycle logistics workforce, this includes the retirement of DAG Chapter 4 “Life Cycle Sustainment” earlier this year in conjunction with the deployment of the new May 2022 DoD Product Support Manager (PSM) Guidebook. The updated PSM Guidebook, along with planned updates to the rest of the “baker’s dozen” of related product support and sustainment guidebooks available in the Integrated Product Support Guidebook Suite now form the basis of key DoD product support guidance. These include the:

• Condition-Based Maintenance-Plus Guidebook

• Integrated Product Support Element Guidebook
• Logistics Assessment Guidebook
• MIL-HDBK-502A, Product Support Analysis
• Operating and Support Cost Management
• Performance Based Logistics Guidebook
• Product Support Business Case Analysis
• Product Support Manager Guidebook
• Public-Private Partnering for Product Support
