You make an interesting point Lamiaa. It definitely becomes a problem when a company strays away from adhering to their design controls. I am not quite sure what you mean when you say that “when the process becomes heavy, they start following the regulation instead of understanding its intent and main purpose”. I hope you can clarify what regulation you are referring to here. Apart from this, I would like to add that this goes hand-in-hand with having a mission statement for the company. If the company deters from the original goal, it starts to become unclear as to what their purpose is. This is why design controls are implemented to make sure companies are keeping track of the products they are putting out in the market and that they are consistent with their original product claims.
