Use Case, Goal, and Scenario Analysis of the Euronet System : Comparing Methods and Results

In this paper, we compare the results of three related requirements engineering efforts: an industrial requirements specification produced with a use case based process, a case study analyzing those use cases by means of goal analysis; and a second case study analyzing the original use cases with an integrated scenario analysis and management approach and software tool support. The scenario-based analysis proved more effective than either of the other two approaches. The results provide validation for both the integrated scenario analysis and the software tool.
