This paper demonstrates the industry-centric approach of predicting defects and controlling them within system testing phase to prevent any escapees to the next testing level and later, to the end users. The importance of knowing total number of defects to be found at the start of system testing phase is a significant element in software engineering practices towards achieving zero known post release defects of the software released to users. Test defect prediction, particularly on functional defects serves as an initiative for test process improvement and optimization. Independent testing team able to discover as many defects as possible, determine when to stop testing, put comprehensive test coverage and ensuring all defects are contained within testing phase.
