Inquiry-Based Scenario Analysis of System Requirements

MetadataShow full item record
The Inquiry Cycle is a formal structure for describing and supporting discussions about system requirements. It divides requirements analysis into three intertwined processes: proposing or writing requirements, challenging or discussing them, and refining or improving them. In this paper, we present an extended example (a meeting scheduler) of the Inquiry Cycle in operation, categorize the types of requirements discussion that occur in practice, and suggest some heuristics for analyzing requirements. We also explain how concrete scenarios improve analysis.
