Quality control and inspections encompass measuring, testing and examining a product and then compare results with specified requirements. The objective is to determine if the output features conform specifications, such as size, function, appearance, and other characteristics that may be relevant to product.
By performing inspections throughout all production processes, we are able to identify problems early, with the goal of eliminating process problems and ensuring that the product meets customers' required expectations.
