DocFlow: workflow based requirements elicitation

Abstract Use 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 alternative technique—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.
