Service-Oriented Design Processes

Service Design Processes and Service-Orientation

The design of services is carried out in two specific phases. The service contract design process represents the first stage during which the technical contract is created, standardized, and finalized. This stage may involve the delivery of a series of contracts or just one, depending on the scope of the service delivery project and the overall methodology being used. At some point thereafter, the actual service logic is designed and then developed in support of the contract. The figure illustrates this simple but important sequence and also reminds us that service-orientation applies to both stages of service design.


Figure: An example of how the design of an entity service is partitioned into contract and logic design stages, both of which are shaped by service-orientation design principles.
