Project description

CREWS was an EU-funded Framework IV 21903 long-term reactive research project into scenario-based requirements engineering. It had 4 academic partners and a steering committee of leading industrial practitioners. Key research results included natural language parsing of text scenarios and scenario-driven goal modelling, eliciting requirements using multi-media techniques, and scenario animation for formal requirement specifications.

At the Centre for HCI Design, we developed new methods and software prototypes for acquiring and validating system requirements in a systematic way. Key features of this research included:

- a critical distinction between use cases and scenarios;
- Methods for discovering socio-technical system requirements from use cases;
- Taxonomies of alternative behaviours with which to discover requirements;
- A simple language for specifying use cases;
- A prototype which automatically generates scenarios from use cases;
- A prototype which automatically generates scenario alternative courses;
- Guided scenarios walkthroughs;
- Patterns for automatic scenario-requirement cross-checking.

Results from this research have been published widely and are also delivered through the CREWS-SAVRE method and software prototype. CREWS-SAVRE was evaluated in the SERPS project with Marconi Naval Systems. CREWS-SAVRE's scenario generation and walkthrough methods and tools are the platform for the ART-SCENE prototype being developed as part of the SIMP project. Further information about the project can be found on the CREWS pages at the University of Aachen or contact Neil Maiden.
