ABSTRACT:
The project shows how the statistical process control charts were capable of tracking the forecast values that were in control and out of control . Additionally, the project shows the benefits of tracking the differences of forecast and sales order to avoid customer order shortages or production write offs. Finally ,the study addresses the importance of statistical process control application & its benefits in other companies ,products . Leading manufacturers take a proactive approach to quality by incorporating tried and true SPC solutions into auditing applications as well as production. They evolve defect detection processes and after‐the‐fact analytical tools into standard practices that reduce variability. Applying SPC techniques to the line tightens the tolerance on variability, resulting in far more efficient raw material utilization, fewer out of spec parts, and less scrap and rework. As a consequence, the end product is of higher quality, customers are happier, costs are lower, and profits are up.
