Defense Acquisition Guidebook

​The Defense Acquisition Guidebook is designed to complement formal acquisition policy as described in DoD Directive 5000.01 and DoDI Instruction 5000.02 by providing the acquisition workforce with discretionary best practice that should be tailored to the needs of each program. The Guidebook is not a rule book or a checklist and does not require specific compliance with the business practice it describes.  It is intended to inform thoughtful program planning and facilitate effective program management.
