The paper presents ~/(&5,72,5( a tool which supports the goal-scenario based approach for requirements engineering developed within the CREWS project. The approach tightly couples goal modeling and scenario authoring to elicit system requirements The approach is supported by guidelines encapsulated in modular method chunks that are assembled in different(More)
Scenarios have been advocated as a means of improving Requirements Engineering. The assumption is that scenarios allow users to better express their requirements (or more generally their knowledge of the constructed system) because they use their own vocabulary. In Europe, a few scenario-based methods and tools have already been developed in research ;(More)

the CREWS 21.903 long term research ESPRIT project has proposed several strategies to support requirements elicitation through textual scenarios analysis. In the CREWS-L’Ecritoire approach, guidelines are proposed to systematise these strategies. However these guidelines have never been evaluated so far. To evaluate the effectiveness of the(More)
A reuse based approach to construct software tool supporting a specific method built « on the fly » is presented in this paper. Its originality is to apply a process view on the reusable component which is either method chunk or software chunk. Our process view leads to construct method and software tool by assembling chunks. Chunks which are either method(More)
