The Department of Transportation (DOT) relies on over 450 information technology systems to conduct business and meet its mission. The Clinger-Cohen Act of 1996 requires each Federal department to develop and maintain an enterprise architecture (EA). An EA—with baseline (as is) and target (to be) architectures, and a sequencing plan—defines the agency’s mission, the information and technologies necessary to perform the mission, and the transitional processes for implementing new technologies in response to changing mission needs. Effective EAs help agencies: integrate; plan changes; avoid duplication of systems; improve information security practices; and optimize the use of limited information technology resources.
We are initiating this audit to (1) determine whether DOT has an effective enterprise architecture program, and (2) to assess its progress in developing its department-wide EA and an EA performance measurement system. We have contracted with KPMG LLP, an independent public accounting firm, to conduct this review subject to our oversight.
