A scenario-based methodology for conducting requirements elicitation

Abstract

Requirements analysis is the process of identifying a user's needs and determining what to build in an a system. Within requirements analysis is the process of requirements elicitation in which tacit information about "what to build" is obtained from the user and his environment. Here, we will describe a methodology, dubbed Scenario Based Requirements Elicitation (SBRE), which structures the early interaction between users and designers in order to quickly develop a set of initial requirements. The methodology features the parallel development of requirements and a high-level design, the use of scenarios to communicate the behavior of a design, an evaluation function to assess the suitability of the design, and an issue base with which to maintain the issues that arise during the elicitation process.
