The design of complex systems is based on the needs and expectations of multiple stakeholders. Analysing such elements and transforming them into a rigorous system specification is a long and demanding task. This research is interested in supporting engineers and other stakeholders in the specification of system requirements with a focus on requirement analysis. The paper presents an approach to conduct analysis of non-functional requirements in a way that benefits both the engineers involved in the development of the current system, and those who will need to make improvements to it. The approach includes suggestions towards a tool, a representation, and a method. The tool is a software tool that specialises in capturing decision rationale known as Decision Rationale editor (DRed); the representation is adopted from the IBIS notation; the method is based on a model synthesised from literature on requirement analysis.
