Yes I agree that design control is an integral process and its failure can have a wide effect. If not done properly, the company will have to make recalls on the product which results in a large loss of money and time. Even worse, if it is a medical device and there is a flaw in its design that is not caught by design controls, it can harm a human being. On a lesser level, if there are minor flaws in the design that don’t have any immediate effect but are documented in the design control, these can be improved upon in future versions of the product.
