The District of Columbia’s City-Wide Enterprise Architecture

The District of Columbia’s Office of the Chief Technology Officer (OCTO) recently completed a set of Citywide Enterprise Architecture (EA) blueprints that illustrate IT systems and enterprise business processes with a near-term focus of the nine Services Modernization Programs (SMP). The Citywide WA is compliant with the Federal Enterprise Architecture Framework Level III. The Citywide EA is comprises four blueprints: business architecture, information architecture, application architecture, and infrastructure architecture. The Citywide EA application blueprint comprises a Services Oriented Architecture for hared software components. Three of these EA blueprints will be published in the District’s IT Strategic Plan 2005-2008. The fourth viewpoint, infrastructure architecture, is classified as Protected Critical Infrastructure Information by the U.S. Department of Homeland Security. In addition, the District is designing long-term Concepts of Operations that constitute strategic program plans and target architectures for each SMP. The District’s to-be planning approach incorporates best practices from Business Process Reengineering and EA.
