This dissertation investigates how a requirements engineer can systematically deduce subsystem requirements specifications from system requirements specifications.
A reference catalogue serves as checklist for the initial system decomposition. The approach for requirements decomposition and refinement uses predicate logics, i.e., assumption/guarantee specifications and decomposition patterns, to deduce subsystem requirements from system requirements. Thereby, both functional and non-functional requirements as well as the precise interrelation between the requirements are covered. A process description illustrates the stepwise application of the approach using a concrete artifact model.
The results are demonstrated with a running example from the automotive domain and are evaluated in a case study with respect to applicability and usefulness.
