The entire procedure is modeled on the needs of quality. It is marked by several rounds of quality-checks, stage-wise division of the manufacturing process and proper monitoring. The checks are conducted by the experts at the end of each stage of manufacturing. To move on to one stage from another the products have to fulfill the quality norms of the host stage. The sieving is done by the experts based on the established criterion of quality. The criterions are separately designed on every finer point of the products. Finally, a stringent inspection is held to detect faults, before the products are released to the market.
