The promises of Service Oriented Enterprise Architecture include greater business agility, improved application integration at reduced cost, and the holy grail of aligning IT initiatives with business objectives. Achieving these goals requires organizations to approach SOA from an Enterprise Architecture perspective. Although existing EA processes and tools can be adapted to facilitate SOA, a new approach is gaining wider acceptance as being especially suited to this task. Capability Modeling focuses on the things that business units can do instead of how they do them. There is a direct corollary to the best practices of service design, where the focus of analysis is on what a service does instead of how it is implemented. Business Capabilities can be described in terms that the business is familiar with, and then mapped directly to services implemented by systems supported by the IT organization. This presentation covers the basics of Capability Modeling and how this important technique can be used by Enterprise Architects to facilitate an SOA adoption program.
