Exploring the characteristics of NFR methods - a dialogue about two approaches

It is not easy to choose a method for eliciting, detailing and documenting non-functional requirements (NFR) among the variety of existing methods. In order to explore typical characteristics of such methods, we compare two approaches which specify NFR: MOQARE and the IESE-NFRmethod.Both aim at deriving detailed requirements from quality attributes, but use different concepts and processes. Our analysis led to ideas for incremental improvement of each method and also to deeper insight into NFR methods.
