This Air Force Instruction (AFI) implements Air Force Policy Directive (AFPD) 17-1, 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, accessible, understandable, linked,
and trustworthy; and ensuring interoperability for Information Technology (IT) and National
Security System (NSS) systems and services that are Air Force only and not subject to
Joint/Department of Defense (DoD) interoperability processes.
This AFI is consistent with DoDI 5000.75, Business Systems Requirements and Acquisition;
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.
