Abstract

A method for scenario-based requirements engineering is described. The method uses two types of scenario: structure models of the system context and scripts of system usage. A modelling language is reported for describing scenarios, and heuristics are given to cross-check dependencies between scenario models and the requirements specification. Heuristics are grouped into several analytic treatments that investigate correspondences between users' goals and system functions; input events and system processes to deal with them; system output and its destination in the scenario model, and acceptability analysis of system output for different stakeholders. The method is illustrated with a case study taken from the London Ambulance Service report. The prospects for scenario-based requirements engineering and related work are discussed.
