Statistical quality control

Certainly nobody wants to purchase any product that is damaged or dysfunctional. No one in his right mind would want to throw away hard-earned money. Practically, everybody wants his money’s worth. As such the quality of a product is very vital in making purchases. As consumers, we always expect products to function properly and work according to how it is designed for. Have you ever tried buying a DVD player and finding out that it only chooses the discs that it plays? Moreover, what about bringing home a newly purchased bag and discovering that the zipper is not functioning? These situations can be very depressing and disappointing. While it is true that manufacturers have full responsibility over their products; it cannot be assumed that these discrepancies are done intentionally. In as much as manufacturers aim for their products to be functional and defect-free, defects are inevitable.Product defects are most observable for products that are mass-produced. In addition, product defects are more significant in manufacturing companies that are not so keen in controlling the quality of their products. If manufacturers want top quality products, measures should be taken in ensuring that product quality is maintained from the beginning of the production process until the end of the production line.

Other manufacturing companies even guarantee the quality of their products way beyond after the products are purchased. As such, these companies offer warranties for their products because these companies are confident that their products are of excellent quality. STATASTICAL QUALITY CONTROL is a ensuring quality control which is integrating quality into the process. Every process should be critically considered and guarded against errors that lead to product defects. However, in reality it is difficult to impose product inspection along every process- so much more if the production is quite large. This is why the task of maximizing the ability to control the quality of the products has become a challenge for most manufacturing companies.
