Characterizing the Implementation of Software Non-functional Requirements from Probabilistic Perspective

Non-functional requirements are quality concerns of a software envisioned. As an effective treatment, goal-oriented method can capture NFR-related knowledge so that an evaluation for a specific implementation strategy can be provided. This paper makes a meaningful attempt to observe the implementation strategies of non-functional requirements in a probabilistic way, and obtain the probabilistic result for each satisficing status. The contribution of our work is to give a clear justification about whether there exists a proper implementation strategy for multiple non-functional requirements so that they can be guaranteed of the specific satisficing statuses, and if so how big the possibility is.
