There are two main users of the IBM® Business Services Composition Studio module: The SOA Architect and the Fabric Developer.
SOA Architect
Rule of thumb - Any service meta data and service interfaces of coarse grained services is defined by the architect.
Fabric Developer
Fabric Developers take direction from Fabric Architects and are responsible for implementing the Fabric services defined by the Architect and these implementations are registered as endpoints in the Fabric meta-model. In some instances these endpoints are built from the ground up based on the specifications laid out in IBM Business Services Composition Studio, in some cases, ISV or Legacy Assets are service enabled.
Rule of Thumb — Developers define fine grained service interfaces and implement both coarse and fine grained services defined by the SOA Architect.
