An Integration of Scenario-Based Requirements Elicitation and Validation Techniques

Scenarios are widely used in industry to support requirements elicitation and validation. Tool support is a prerequisite for effective use and management of scenarios. In this paper we propose to integrate two scenario-based techniques developed in the ESPRIT Project CREWS. One supports the elicitation of a goal model from real-world scenarios. The other allows to validate a formal system specification by playing instancelevel scenarios against it. Interestingly, the two of them complement each other in various respects. We outline the benefits obtained by integration and present how we performed it at the conceptual and technical levels. The resulting integrated environment has been validated on a small case study in the manufacturing domain.
