Abstract

Scenarios have proven useful to elicit, validate and document requirements but the development of new methods and tools for Requirements Engineering integrating scenario based approaches has been limited. The view developed in this paper is that scenario based approaches should be looked upon as reusable components. Our concern is therefore twofold : first, to represent scenario based approaches in a modular way which eases their reusability and second, to specify the design context in which these approaches can be reused in order to facilitate their integration in existing methods. The paper presents also an implementation of our proposal using SGML-HTML to store scenario based approaches in the multimedia hypertext documents and illustrates the retrieval of components meeting the requirements of the user by the means of SGMLQL queries.
