A
business analyst, domain expert, and/or
enterprise architecture team will develop the organization's service model first by defining the top level business functions. Once the
business functions are defined, they are further partitioned and refined into services that represent the processes and activities needed to manage the assets of the organization in their various states. One example is the separation of the business function "Manage Orders" into services such as "Create Order", "Fulfill Order", "Ship Order", "Invoice Order" and "Cancel/Update Order". These business functions have to have a
granularity that is adequate in the given project and domain context. Many analysis and design methods can be used for service engineering, both general purpose ones such as OpenUP and
Domain-Driven Design as well as those discussed under
Service-oriented modeling. == Bibliography ==
