Enterprise Architecture
Agencies shall develop an enterprise architecture (EA) that describes the baseline architecture, target architecture, and a transition plan to get to the target architecture. The agency’s EA shall align to their IRM Strategic Plan. The EA should incorporate agency plans for significant upgrades, replacements, and disposition of information systems when the systems can no longer effectively support missions or business functions. ( OMB Circular A-130.Managing Information as a Strategic Resource. Page 6.)
