Abstract

In many software organizations, defects are classified very simply, using categories such as Minor, Major, Severe, Critical. Simple classifications of this kind are typically used to assign priorities in repairing defects. Deeper understanding of the effectiveness of software development methodologies and techniques requires more detailed classification of defects. A variety of classifications has been proposed.Although most detailied schemes have been developed for the purpose of analyzing software processes, defect classification schemes have the potential for more specific uses. These uses require the classification scheme to be tailored to provide relevant details. In this vein, a new scheme was developed to evaluate and compare the effectiveness of software inspection techniques. This paper describes this scheme and its use as a metric in two empirical studies. Its use was considered successful, but issues of validity and repeatability are discussed.
