Historically, the identification and correction of inadequacies in the process of software production called process feedback has been a difficult, time-consuming, manual exercise. Recently, a methodology for process feedback, called attribute focusing, has been developed. The authors compare post-process feedback with and without attribute focusing to determine how the methodology fares against current practice in post-process correction. Five project teams analyzed post-process defect data and made recommendations to improve the quality of a large operating systems product. That data was based on a multiple-choice questionnaire that was completed for every defect in a sample of defects that was chosen by each team. Subsequently, the same data was reanalyzed using attribute focusing. The comparison suggests attribute focusing can do at least as well or better than current practice in postprocess analysis, while reducing cost of analysis substantially.< >

Software recreates are necessitated due to inadequate diagnostic capability following a failure. They impact the service process and the perception of availability, but have never been adequately quantified. This paper develops a technique to make the key measurements of: percent recreate, arrival rate and open time, from problem service data without requiring any additional instrumentation. The study is conducted over an 18 month period on two operating system products, that are among the best in the industry for diagnosis and service. The results provide the first insight into the problem and some accurate baselines.
Software engineering is a growing part of computer science. Software engineering attempts to put measurements and metrics into the area of software programming. One of these metrics, Halstead's software science [1...
