In the software-development life cycle, various reliability assurance techniques are routinely performed in an attempt to reduce the number of errors in a software product. These reliability-assurance techniques commonly consist of a variety of technical reviews and several levels of testing. Although the utilization of these techniques is growing, there is a lack of quantitative data on their effectiveness. This paper describes two metrics, error-detection efficiency and cost effectiveness, which were used to evaluate the reliability-assurance techniques employed in a large software project. The results of the study are also presented.
