Abstract
Problems with consolidating, disseminating, and ensuring integrity of corporate data management continues to confront the information systems leadership in organizations. To address these problems some organizations are employing Service Oriented Architectures (SOA) as a paradigm, which is enhanced by the use of Web services to provide a lightweight means of leveraging resources. The Federal Financial Institutions Examinations Council (FFIEC) is one such organization. In this paper, we have used the traditional systems analysis and design (SAD) principles to frame how the FFIEC employed SOA as a new paradigm of conducting business with Web services enabled by a particular XML based instantiation: eXtensible Business Reporting Language (XBRL). Using qualitative methods, we provide a methodological guide in the form of questions organizations should address in SOA projects that particularizes SAD principles for SOA. The questions derive from merging analysis of the data collected regarding the SAD efforts at the FFIEC coupled with principles asserted in traditional SAD literature. We also present lessons learned by the FFIEC while progressing through the planning, analysis, design, and implementation phases to achieve quality and flexibility in its information supply chain.
