Verification of Non-functional Requirements Using Formal Semantics

Studies have shown that finding defects in a software system is much cheaper in terms of both money and time spent when done during requirements analysis, as opposed to development or testing. To this end, significant advances have been made in the early detection of system defects. However, research on exposing unexpected system behaviors is relatively scant, especially regarding to non-functional requirements (NFRs). We propose a model-driven approach grounded in formal semantics to expose unexpected behaviors in a set of NFRs and propose future work for evaluating the effectiveness of such an approach.
