What this publication covers

This publication establishes policy and assigns roles and responsibilities for developing, maintaining, storing, and implementing sound integrated and interoperable architectures across the Air Force for Information Technology (IT) and National Security System (NSS) across the four DoD mission areas to support decision-making processes and ensure the alignment of Air Force’s IT and NSS environment with the critical mission needs of the Air Force. It redefines the Air Force Enterprise Architecture (AFEA) framework and removes architecture approval and certification guidance and removes the Terms of Reference for the Architecture Executive Committee and Architecture Development Working Group.
