SOA's contribution to software engineering is under hot debate and discussion but I assert one of its impacts is in the area of both how we capture business requirements and how those requirements are communicated from business to IT. The notion of a service requires that business no longer push functionality to IT which is housed in silo applications, the function oriented approach. Instead services become first class constructs where they represent an application has more granular reusable assets called services. This changes the software engineering approach in several ways. One notable way is in how many organizations do use cases which have a large amount of behavior of things that occur on the glass, the user interface.
The change in development approach is that the service would be identified prior to use case development and as part of either understanding the business process, its re-engineering or its optimization. Separate use cases would be developed to represent the business functionality needs of the service versus the user interface work flow and design. This will allow for improved separation of concerns down stream during design and development.
But the big point is that this is complimentary to MDA as SOA builds or adds to best practices it does not conflict.
