DoD has taken a federated approach for developing and managing the DoD EA that is based on enterprise-level guidance, capability areas, and component architectures. A Federated DoD EA is the best way to effectively describe a complex Department and provide the necessary context and guidance to govern, manage, and accomplish the missions of the Department. This approach is described in a Federation Strategy that is currently being updated. The strategy describes an approach to enterprise architecture that facilitates interoperability and information sharing between semi-autonomous departments, components and programs. This approach recognizes the need for autonomy but requires linkages and alignment of architectures from the Program level up to the Enterprise level. A governance body and associated processes are in place to provide the necessary governance and oversight with respect to the strategy. The Governance body consists of subordinate working groups that contain Department-wide representation. Requirements for DoD EA compliance are captured in the CIO approved DoD Information Enterprise Architecture (IEA) document that is posted on the CIO public site for departmentwide use.
