An XML environment for scenario based requirements engineering

The pervasive use of scenarios in the development of computer systems and software has motivated the need of formalisms and tools for the description and manipulation of scenarios. To this aim, we present SME (Scenario Model Environment), an XML based tool for scenario-based requirements engineering. The tool enables to exploit the emerging XML technologies in order to offer powerful ways to create, maintain, distribute and use scenarios. We have widely experimented SME through several case studies, ranging from small examples, like a library system, to complex industrial applications.
