UCMExporter: Supporting Scenario Transformations from Use Case Maps

Abstract: The Use Case Maps (UCM) scenario notation is applicable to many requirements engineering activities. However, other scenario notations, such as Message Sequence Charts (MSC) and UML Sequence Diagrams (SD), have shown to be better suited for detailed design. In order to use the notation that is best appropriate for each phase in an efficient manner, a mechanism has to be devised to automatically transfer the knowledge acquired during the requirements analysis phase (using UCM) to the design phase (using MSC or SD). This paper introduces UCMEXPORTER, a new tool that implements such a mechanism and reduces the gap between high-level requirements and detailed design. UCMEXPORTER automatically transforms individual UCM scenarios to UML Sequence Diagrams, MSC scenarios, and even TTCN-3 test skeletons. We highlight the current capabilities of the tool as well as architectural solutions addressing the main challenges faced during such transformation, including the handling of concurrent scenario paths, the generation of customized messages, and tool interoperability.
