They can use such information in prioritizing software testing and allocating resources accordingly. However, our experience shows that it is difficult to collect and analyze fine-grained test defects in a large and complex software system. On the other hand, previous research has shown that companies can safely use cross-company data with nearest neighbor sampling to predict their defects in case they are unable to collect local data. In this study we analyzed 25 projects of a large telecommunication system. To predict defect proneness of modules we trained models on publicly available Nasa \MDP\ data. In our experiments we used static call graph based ranking (CGBR) as well as nearest neighbor sampling for constructing method level defect predictors. Our results suggest that, for the analyzed projects, at least 70% of the defects can be detected by inspecting only (i) 6% of the code using a Naïve Bayes model, (ii) 3% of the code using \CGBR\ framework.
