Executive Summary (This is a document excerpt)

Forrester recently surveyed 20 federal enterprise architects to discover how they view the role of service-oriented architecture (SOA) in their agencies. They tell us that both the program areas and agency IT groups appreciate the value of SOA. More significantly, they report that their agencies have committed to SOA and incorporated it into their enterprise-level strategies to a far greater degree than Forrester's Business Technographics® surveys have found in most other enterprises. So is SOA a perfect fit for modernizing and transforming federal agencies? It's not a slam dunk. While agencies can work to fine-tune the interactions between program and IT staff to improve SOA planning, there is a fundamental obstacle: SOA changes the granularity of applications and provides an opportunity to reuse existing components, but procurement processes are geared toward entire solutions, not combinations of internal and external application components. Architects must make sure that their procurement processes are mature enough to exploit service repositories just as they have incorporated technology architecture standards into requests for proposals (RFPs).
