Determining the quality of a software product basically deals with checking the fulfillment of functional and quality requirements. Therefore, specifying useful and testable quality requirements is a central challenge. Many existing approaches focus on eliciting quality requirements, but often neglect the specification of respective test criteria. We present a bipartite approach that focuses on collecting testable quality requirements with quality models or goals as initial input. Firstly, using operational quality models enables us to derive measures in a goal-oriented approach that serve as basis for the specification of testable quality requirements. Secondly, identifying obstacles that obstruct goals helps closing gaps and enhances quality models. Our approach contributes to sharing and reusing common quality requirements by facilitating their specification based on a quality model. An initial application of our approach shows that it leads to quality requirements with clear criteria for testability. Nonetheless, the approach requires further applications in order to validate it in more detail and to identify improvement potentials.
