It would obviously be very valuable to know in advance which files in the next release of a large software system are most likely to contain the largest numbers of defects. To accomplish this, we developed a negative binomial regression model and used it to predict the expected number of bugs in each file of the next release of a software system. The predictions are based on code characteristics and bug and modification history data. We will discuss what we have learned from applying the model to make predictions for 170 releases of nine large industrial systems, each with multiple years of field exposure, and tell you about our success in making these predictions. We'll also discuss some of the lessons learned and issues that had to be dealt with.
