: Scenario-based approaches are becoming ubiquitous in systems analysis and design but their definition and scope remain vague. Complementing the recently proposed CREWS classification framework for scenario-based RE, this paper reports on an exploratory survey of practice conducted through site visits with 15 projects in four European countries. The main findings include that: (1) the variety of purposes and uses of scenarios in the process is much greater than expected; (2) as a consequence, we must take scenarios much more seriously as important design artifacts, offering better means for structuring, management, and evolution. To handle these complex processes, users request more explicit methodological guidance and more adequate tool support.
