2 Scenario Integration into Requirements Engineering Methods 1

Scenario Based Requirement Engineering (RE) techniques have for main motivation the opening of Requirement Engineering processes to neophytes. By combining the methodological approach of requirement analysis to informal descriptions, they increase productivity into classical RE techniques. In this context, an important problem is the integration of scenario approaches into RE methods. This paper presents a knowledge base of different scenario chunks which allows to identify the scenarios appropriate to the context of the RE project, and to integrate them into any RE methods. The identification of scenario chunks is partly based on the internal properties of scenarios which are extensively described in a framework for scenario classification
