Service-Oriented Architecture

This paper presents an overarching metamodel for service-oriented architecture roadmapping (SOAR). An SOA roadmap is of paramount importance to strategize and operationalize an effective SOA program in a heterogeneous enterprise computing environment. There are 20 steps defined in the framework, broken down into 4 streams: Planning and Analysis, Design and Construction, Deployment and Operations, and Management and Governance. The key inputs and prerequisites are specified for each step in the major streams. The detailed artifacts in each step are articulated in the context. This roadmap can serve as a holistic blueprint to adopt and implement SOA in a large organization.
