Scenario reuse: a technique for complementing scenario-based requirements engineering approaches

In recent years, the use of 'scenarios' have been recognised as an important tool in requirements engineering (RE), and has led to a number of scenario-based RE approaches being proposed (Potts et al., 1995; Jacobson 1995; Hsai et al., 1995). This paper presents an approach for reusing scenarios, called SCORE (SCenario-Oriented REuse), which is intended to complement existing scenario-based RE approaches. We describe our application of SCORE on two case studies, and discuss the issues that have surfaced from each. We also compare SCORE with other approaches to reuse at the RE level. Finally, we summarise our experience of scenario reuse by outlining the questions that need to be addressed by a more comprehensive model of the scenario reuse process.
