An overview of a SysML extension for goal-oriented NFR modelling: Poster paper

Abstract

To develop quality software and systems, both functional and non-functional requirements need to be taken into account at the highest level of abstraction. However the issue of relationships between non-functional requirements and functional requirements has been rarely addressed. In this article, we outline an extension of the SysML requirements meta-model with relevant concepts of commonly used goal-oriented requirements engineering approaches. The main contribution of our approach is to analyse and describe the impact of non-functional requirements on functional requirements.
