Abstract

Defect-detection techniques, like reviews or tests, are still the prevalent method to assure the quality of software. However, the economics behind those techniques are not fully understood. It is not always obvious when and for how long to use which technique. A cost model for defect-detection techniques is proposed that uses a reliability model and expert opinion for cost estimations and predictions. It is detailed enough to allow fine-grained estimates but also can be used with different defect-detection techniques not only testing. An application of the model is shown using partly data from an industrial project.
