They practice on removal of the causes of imperfect quality. Prevention is better than cure. As and when there is a non-conformance detected, initially the piece is rejected.
Every rejected piece is rechecked to find the reason for rejection. There is an in depth study of the reason if it repeats. The root cause behind the reason is identified. The technical director sets up a team of two or three people to find the best solution for elimination of the root cause. Further, the steps taken are documented and given to the respective departments. This makes it sure that the root cause does not come up again.
The system is so effective that the rejection goes down very fast and the staff too becomes aware of the causes and are conscious to such an extent that rejections are prevented.
Further, Laboratory testing, Observational checking Stage wise QC all add up to form a perfect QC system that gives out uniform consistent quality batches of the product.
Further to this the Technical Director strives to check the attitude of the manpower by regular team meetings. He improves their way of thinking by constantly, training and motivating them for giving out best results. He also encourages team spirit. The tests carried out at different stages and their respective results vis-à-vis the industry standards are shown in the table |
