handle is hein.gao/gaobaameb0001 and id is 1 raw text is: im Accountability * Integrity * Reliability United States General Accounting Office Washington, DC 20548 March 28, 2003 The Honorable John Ensign Chairman The Honorable Daniel K. Akaka Ranking Minority Member Subcommittee on Readiness and Management Support Committee on Armed Services United States Senate Subject: Information Technology: Observations on Department of Defense's Draft Enterprise Architecture The fiscal year 2003 Defense Authorization Act' requires the Department of Defense (DOD) to develop by May 1, 2003, a financial management enterprise architecture, including a transition plan, that meets certain requirements. The act also requires that we submit to congressional defense committees an assessment of the architecture and transition plan within 60 days of their approval. (See enclosure I for the requirements of this law.) As part of our ongoing work to satisfy this legislative requirement and at the request of your staff, we briefed your offices on March 4, 2003, on our preliminary assessment of the DOD draft architecture products dated February 7, 2003. As further requested by your staff, this letter transmits the observations we made during the briefing. (See enclosure II for a summary of our assessment approach.) An enterprise architecture provides a clear and comprehensive picture of an entity, whether it is an organization (e.g., federal department or agency) or a functional or mission area that cuts across more than one organization (e.g., financial management or homeland security). This picture consists of snapshots of both the enterprise's current operational and technological environment and its target environment, as well as a capital investment road map for transitioning from the current to the target environment. These snapshots further consist of views, which are basically one or more architecture products that provide conceptual or logical representations of the enterprise.
