Abstract
A method of identifying unacceptable levels of defects in specific sections or work centers of a manufacturing process on a real time basis and initiating corrective action is disclosed. The system allows a user to define defect tolerances or thresholds for manufacturing work centers, tracks defects at the work centers, compares the level of faults with the tolerances, reports out of tolerance work centers, automatically initiates contact with the appropriate personnel to affect a correction to the out of tolerance work center, and maintains records of corrective actions taken.
