An empirical investigation of software fault distribution
Karl Heinrich Möller, Daniel J. Paulish · 2002
The paper investigates the distribution of faults within three evolutionary versions or releases of a system software product. A greater concentration of faults was found in certain software program modules as compared to other modules. The fault rates are correlated to the percentage of new and changed lines of code, the module size, and the programming languages used. Additionally, a number of purely qualitative reasons for the observed concentration of faults are asserted.>
