Information Dominance Governance and Management, and Headquarters Air Force Mission
Directive (HAF MD) 1-26, Chief Information Dominance and Chief Information Officer. It
provides guidance for developing, maintaining, and implementing sound integrated and
interoperable architectures across the Air Force; making architecture data discoverable,

only and not subject to Joint/Department of Defense (DoD) interoperability processes.

Chairman Joint Chiefs of Staff Instruction (CJCSI) 3170.01I, Joint Capabilities Integration and
Development System (JCIDS); Manual for the Operations of the Joint Capabilities Integration
and Development System; and Air Force Manual (AFMAN) 33-363, Management of Records.
This publication applies to individuals at all levels who prepare, manage, review, certify,
approve, disseminate and/or use official Air Force architectures and interoperability assessments,
including the Air Force Reserve (AFR) and Air National Guard (ANG), except where noted
otherwise.
