Towards a Design Method Supporting the Alignment between Business and Software Services

This paper proposes and illustrates an approach to identify and specify requirements on information-based business services and their associated derived software services. The approach proposes first to identify business services by modeling business requirements using the goal oriented modeling notation i*. Then, in a second phase, the identified services are refined according to these requirements using UML activity and class diagrams. This specification is based on a method and a supporting toolset, called "Efficient". The approach is illustrated through the handling of a case study in the tourism sector.
