Knowledge transformation from task scenarios to view-based design diagrams

A large body of research in software requirement engineering domain has been dedicated to enhancing the structure of task scenarios using scenario schemas and predefined structures. However, less attention has been paid to the application of schemas in extracting design knowledge from scenarios. In this paper, we propose a schema-based technique to extract the design knowledge embodied in the text of scenarios and represent them using multi-view design diagrams. In this context, we define a framework and a scenario syntax that allow for generating a set of structured scenarios that cover the requirements of a software system. We define a novel scenario schema to parse the informal text of scenarios and populate an objectbase to maintain the design knowledge building blocks. Consequently, a set of guidelines are defined to incrementally build design diagrams for software views such as data and function. As a case study, the design diagram generation for a restaurant system is presented.
