To facilitate efforts to transform the federal government into one that is citizen-centered, results-oriented, and market-based, the Office of Management and Budget (OMB) is developing the Federal Enterprise Architecture (FEA), a business-based framework for government-wide improvement. As illustrated in Figure 1, the FEA is being constructed through a collection of interre-lated “reference models” designed to facilitate cross-agency analysis and the identification of duplicative investments, gaps, and opportunities for collaboration within and across federal agencies.
This document, developed by the Components Subcommittee of the Federal CIO Council Ar-chitecture and Infrastructure Committee, compliments the SRM by discussing the concepts of service component-based architectures and placing them in the context of the FEA. The pur-pose of this paper is to inform agencies’ thinking on development and use of enterprise archi-tecture, in a manner consistent with component sharing and reuse, and the objectives of the FEA. The Subcommittee will evolve this document as agency enterprise architectures and the FEA mature.
Successful service-oriented, component-based architectures will greatly serve the needs of the Federal community as the community works to ensure information technology (IT) capabilities are managed in a structured enterprise-wide technology and business process lifecycle. Ex-perience with component-based architectures has shown that reuse can be successful when the reuse efforts focus on large business level components in a collaborative environment that includes system owners, capital planners and enterprise architects.
