User Scenarios Through User Interaction Diagrams
Douglas Hiura Longo, Patrícia Vilain · International Journal of Software Engineering and Knowledge Engineering · 2015
This paper investigates the applicability of User Interaction Diagrams (UIDs) as user scenarios for the specification of software requirements by non-technical customers. Two methods for building user scenarios using UIDs were proposed: the progressive and the regressive methods. These two methods were applied in an experiment where the results demonstrated that the regressive method requires significantly less effort as compared to the progressive method. Furthermore, there was a significant difference in the quality of diagrams obtained from each of the two methods. In our experiment, the regressive method resulted in better quality factors.
