Implementation and Use of DON Enterprise Architecture Hierarchy
DON CIO Memo - Publish Date: 01/06/09
This memo promulgates policy defining the initial implementation and directs the use of the DON Enterprise Architecture (EA) Hierarchy. The DON EA Hierarchy provides a structure to relate the complete set of activities occurring within the DON. The hierarchy is a key component of the DON EA intended to provide a means for senior leaders to make informed decisions and relate activities and capabilities within the DON to the Joint Staff Capability Areas (JCA). The JCA serves as the Department of Defense’s common framework and lexicon for the organization of capability portfolios.
