Interactive Use Case

Abstract

In this paper we present a proposal for a pictorial and interactive tool positioned in between Use Cases and Mock-up. We call the tool "Interactive Use Case" (ruC), underlining the participatory nature of system definition. The ruc can provide a common place to structure and record the dialogue between system developers and system users. We describe a case study, in which ruc were used in the analysis of a complex information system where the number of factors to be taken into account and their variability are extremely high. The information system was used to support the definition of meta-models, which described cost analysis, management and reduction for maintenance, repair and operations. Because the information system is used for a variety of customers, it must be able to adapt to different maintenance and repair practices. Interactive Use Cases played a critical role during the participatory definition of this system.
