Quality inspection also refers to the actual inspection of products. It is vital to provide quality products to consumers that comply with all market regulations. Customers pay for and expect quality and therefore, top-quality products need to be delivered without fail. There are many quality control methods, and many of them are industry specific. A significant aspect of quality inspection is the establishment of well-defined controls. These controls help standardize both production and reactions to quality issues. Quality inspection involves testing units and determining if they are within the specifications for the final product. Quality inspection creates safe measures that can be implemented to make sure deficient or damaged products do not end up with customers.
