Quality analysis of NL requirements: an industrial case study

Nowadays common practice indicates that the requirement engineering (RE) process critically influences the success of the system development life cycle. Several commercial tools allow to classify, archive and manage requirements and then to print out reports and requirement documents. QuARS (Quality Analyzer for Requirements Specifications) is an automatic analyzer of such requirement documents, developed by ISTI-CNR, that can be adopted to evaluate the document quality by linguistic point of view. This paper presents how a requirement management tool, an automatic document generator, and QuARS can be integrated to define an RE automation support. The case study investigates and highlights the efficacy and the role of such proposed support in the Siemens C.N.X. development process.
