Then the results of the full scale defect density assessment surveys are compared to each project in our database.  The project that is the closest to yours in terms of matching each of the survey questions is determined and the actual defect density associated with that project is returned.  The closest defect density database match is typically the most accurate predictor of software defect density as long as the surveys are completed completely and accurately.
