Large Scale Requirements Analysis as Heterogeneous Engineering

We examine how to improve our understanding in stating and managing successfully requirements for large systems, because the current concept of a system requirement is ill suited to develop true requirements for such systems. It regards requirements as goals to be discovered and solutions as separate technical elements. In consequence, current Requirements Engineering (RE) theory separates these issues and reduces RE to an activity where a technical solution is documented for a given set of goals (problems). In contrast, we advocate a view where a requirement specifies a set of mappings between problem and solution spaces, which both are socially constructed and negotiated. Requirements are…
