Presentation
Case Study: EA at the GSA (US General Services Administration)
We will present recently completed and ongoing efforts of the US General Services Administration (GSA), the largest US Government procurement focused organization, to develop an agency-wide, comprehensive and coherent Enterprise Architecture (EA). It reviews the path taken by GSA to embrace the Object Management Group's (OMG) Model Driven Architecture (MDA) EA standards It examines how it went from a Proof-of-Concept through a Pilot to implementing an approach that embraces customer-focused Value Chain Analysis and MDA to arrive at a top-down target Architecture: OneGSA.

The presentation demonstrates how this approach helped GSA to reach a status of "green" in its EA as defined by the US White House's Management Agenda in April of 2005. It then demonstrates how the basic EA principles utilized are extended to develop system specification that will, within the next few months, be the basis for a Request for Quotation (RFQ) to modernize portions of GSA's Financial Operations. This presentation gives a compelling argument for a business-driven, top-down approach to EA development and implementation.
