Information and Software Technology, 45(6), 357-369. doi:10.1016/s0950-5849(03)00031-4http://repositorio.grial.eu/handle/grial/522Use cases are the favoured technique for defining the functional requirements of a software system, but their use implies that the desired functionality of the new system is well known. The aim of this work is to present an alternate procedure -and a supporting tool- to accurately define this functionality, expressed as use cases, starting from the workflows that describe the end user work. The use of hypergraphs in the proposed algorithm of transformation reinforces the generation process. In addition, the technique is independent of the development paradigm and a variation in the algorithm allows obtaining Data Flow Diagrams.enrequirements engineeringCASE toolworkflowuse caseDFDrequisitos de ingenieríaflujo de trabajocaso de usoArticle
