HUD'S Enterprise Architecture (EA) Practice has made significant progress defining core business, information, and technology requirements to support the CIO's leadership in modernizing the Department's information technology environment. The EA Practice ensures conceptual alignment to modernization best practices and facilitates managed change.

Maintenance of old systems limits the deployment of more efficient IT solutions. The very high maintenance cost of legacy systems depletes the pool of new system development resources. Currently, HUD has approximately 200 information systems that execute overlapping business and information management processes, and rely on diverse technologies that are expensive to maintain. Furthermore, large business capacity gaps exist because old proprietary technologies are not flexible and scale poorly with new IT solutions.

The EA Practice has created a problem-solving framework and solution methodology that rapidly defines common ways to implement technology transformations. HUD's EA Practice leverages the Enterprise Architecture V5.0 as a foundation for guiding strategic portfolio decisions, and the creation of the EA Transition Plan gives HUD a common, enterprise-wide migration path toward business and IT modernization
