While working at General Dynamics Electric Boat on submarines, I took part in most of the design controls outlined in lecture and my experience was fairly similar to what was outlined in class except my company could benefit from some design controls we don’t have (no DHF). For the most part, I think it is similar across industries and very necessary.  
 
In my experience, the planning stage is pretty much what was outlined in lecture. We would put together a DDP (didn’t call it that but same thing) and gather design input. A DSD (didn’t call it that but same thing) would be made to outline specifications or how we plan to do the design input. Verification was the same but validation was a little different. Validation wasn’t so focused on the user, rather, it was emphasized that one should engineer something that is functional first and then consider the user second. We were told to engineer what the user had in mind but to remember that sometimes the user doesn’t have an engineering background and can ask for some rather dangerous things. That being said, safety, functionality were first and what the user wanted or “feel” was last or not considered at all. Design transfer, design change requests and design review meetings was pretty much exactly what was described.
