service-oriented design

The service-oriented design phase represents a service delivery lifecycle stage dedicated to producing service contracts. It can therefore be considered a formal representation of the well-established "contract-first" approach to software development.

The typical starting point for the service-oriented design process is a service candidate that was produced as a result of completing all required iterations of the service-oriented analysis process. Service-oriented design subjects this service candidate to additional considerations that shape it into a technical service contract in alignment with other service contracts being produced for the same service inventory.

There is a different service-oriented design process for each of the three common service models (task, entity, and utility). The variations in process steps primarily accommodate different priorities and the nature of the logic being expressed by the contract.
