ElicitO: A quality ontology-guided NFR elicitation tool

Abstract

Despite the importance of capturing a precise and complete set of requirements in the requirements engineering stage, there are few tools that adequately support requirements analysis in the process of capturing quality related requirements (non-functional requirements). This paper presents ElicitO, a requirements elicitation tool aimed at empowering requirements analysts with a knowledge repository that helps in the process of capturing precise nonfunctional requirements (NFRs) specifications during elicitation interviews. The approach is based on the application of functional and non-functional domain ontologies (quality ontologies) to underpin the elicitation activities. The tool is used as a memory aid to structure elicitation interviews, guide requirements analysts with regard to the important quality aspects relating to a class of applications, and support the development of precise requirements based on characteristics and metrics available in quality model standards. © Springer-Verlag Berlin Heidelberg 2007.
