Inspection is a highly effective but costly technique for quality control. Most companies do not have the resources to inspect all the code; thus accurate defect prediction can help focus available inspection resources. BugCache is a simple, elegant, award-winning prediction scheme that "caches" files that are likely to contain defects . In this paper, we evaluate the utility of BugCache as a tool for focusing inspection, we examine the assumptions underlying BugCache with the aim of improving it, and finally we compare it with a simple, standard bug-prediction technique. We find that BugCache is, in fact, useful for focusing inspection effort; but surprisingly, we find that its performance, when used for inspections, is not much better than a naive prediction model - viz., a model that orders files in the system by their count of closed bugs and chooses enough files to capture 20% of the lines in the system. © 2011 ACM.
