Service-oriented architecture (SOA) has become popular as an approach to developing flexible, modular systems. Academic studies of SOA as a systems development philosophy abound, and recent industry surveys indicate that most firms are actively pursuing SOA initiatives. The authors used a rigorous case study methodology to examine five main benefits of SOA---business flow transparency, plug-and-play capability, leveraging legacy systems, rapid product development time, and reduced costs---as perceived by organizations that have implemented SOA. Participants in this study report that not all stated benefits are realized because of, among other things, a failure of service-oriented thinking at an organizational level, problems allocating financial responsibility for services within and between organizations, and a lack of mature tool chains. Study participants saw these issues as critical to leveraging SOA investments.
