Enterprise service delegation pattern

Enterprise architecture is an emerging field of study. There are multiple areas that provide building blocks for this discipline including information technology and business management. Information technology plays a vital role in shaping the direction of business. In a granular level, business processes can be mapped to hardware and software automated processes. Service oriented architecture (SOA) is a popular architecture for providing business services in the form of software and hardware services. A software service can represent a business service partially or fully. Developing architectural building blocks is a common practice recommended by open group. This paper presents one such building block in the form of software design pattern. The enterprise service delegation pattern provides a structure to arbitrate service calls. This pattern is being used to construct enterprise service buses.
