CREWS - SAVRE : Systematic Scenario Generation and Use 1

CREWS-SAVRE is a prototype software tool for systematic scenario generation and use. This paper reports on two interleaved strands of research and development of CREWS-SAVRE. The first is theoretical research into classes of exceptions in software-intensive systems. The second is the development of a software prototype which has been used to acquire requirements from current scenario users. This paper reports these user requirements and design implications for the current version of the prototype. The paper ends with a discussion of the advantages of integrating basic software engineering research with user-centred system design. There has been considerable recent interest in the use of scenarios to acquire and validate system requirements. However, few methods or software tools are available to achieve systematic scenario use, or even to generate useful scenarios in the first place. A recent analysis of scenario use by practitioners reveals that current commercial methods and software tools provide insufficient and unsystematic guidance for requirements acquisition and validation [1].
