In my opinion quality control is an integral part of any company and is worth every single dollar spent on it. Companies serve to customers who have specific needs and it is the quality engineers’ responsibility to make sure that the products developed by that company meet those needs. They go through a list of specifications and evaluate the product output against these specifications. If something is wrong, then they have to go back and find the root cause to prevent further and possibly bigger issues in the future. This department is especially important in a medical device or pharmaceutical industry where serious harm can be done to human health by releasing unsafe and poor quality products.
