Improvements in or relating to the prediction of product defects

摘要

A software predictive engine is described that provides a tool to analyze the import of defection the software development process. By providing a prediction of escaping defects, in terms of the normalized sigma measure and the predicted lines of code, together with historical data the impact of defects at the stages of the design can be predicted. As actual defects are measured predicted sigma level can also be predicted. The engine includes generating a defect containment matrix for the historical data and for the current software program being developed. <IMAGE>
