ABSTRACT

Defect severity that is a measure of the impact caused by the defect plays an important role insoftware quality activities because not all software defects are equal. Earlier studies have concentrated ondefining defect severity levels, but there have almost never been trials of measuring module severity. Inthis paper, first, we define a defect severity metric in the form of an exponential function using thecharacteristics that defect severity values increase much faster than severity levels. Then we define anew metrics set for software module severity using the number of defects in a module and their defectseverity metric values. In order to show the applicability of the proposed metrics, we performed ananalytical validation using Weyuker’s properties and experimental validation using NASA open data sets. The results show that ms is very useful for measuring the module severity and msd can be used to compare different systems in terms of module severity.
