Introduction to the US Army PEO Aviation (PEO AVN) Enterprise Architecture Framework (EAF)

The purpose of this paper is to present the technical details of the US Army Program Executive Office - Aviation (PEO AVN) Enterprise Architecture Framework (EAF) while describing its development status as of January 2024. The Future Vertical Lift (FVL) Program developed and continues to improve the FVL Architecture Framework (FAF) (Ref. 1) for use by FVL programs. The EAF is intended to be compatible with the FAF and to provide specific guidance to enduring programs. The EAF contains modeled content from the FAF and employs a technical approach that contains different perspectives for enterprise (i.e., PEO AVN) and program users depending on how the EAF will be used. As an architecture framework, the structure of the EAF follows International Standard ISO/IEC/IEEE 42020 (Ref. 2). The EAF prescribes the conventions, principles, and practices for the development of the Enterprise Architecture (EA). The EA communicates the technical, business, and organizational architecture of the enterprise for the purpose of enabling Modular Open System Approach (MOSA) (Ref. 3) objectives, such as improved affordability, increased readiness, enhanced capabilities, reduced schedule pressure, and reduced supply chain risk.
