Deriving Use Case Diagrams from Business Process Models

In this paper we introduce a technique to simplify requirements capture. The technique can be used to derive functional requirements, specified in the form of UML use case diagrams, from existing business process models. Because use case diagrams have to be constructed by performing interviews, and business process models usually are available in a company, use case diagrams can be produced more quickly when derived from business proces models. The use case diagrams that result from applying the technique, specify a software system that provides automated support for the original business processes. We also show how the technique was successfully evaluated in practice.
