Taxonomy for requirements analysis

Techniques that are claimed to be applicable to analysing requirements for software intensive systems have been available for many years, but the extent to which they address this problem for large, complex systems is open to question. The techniques tend to focus on aspects of the system that are understood by specialist system designers, rather than on the issues that concern its prospective owners and users. It is not always clear how, if at all, some of these concerns may be analysed using existing techniques. This taxonomy provides a framework for classifying techniques according to the concerns that need to be addressed and the abstract frames in which analysis might be performed. Identification of all concerns reveals analysis needs, that must be satisfied by the set of abstract frames in which aspects of the system are modelled. Populating the taxonomy can identify where techniques are already available and where further research is needed
