Question about relation between measure department and customer

here we're usually a subcontractor so getting a drawing change requires 1) we submit a request to our customer 2) they decide if it needs to be changed then 3) they have to go through the print change request process with their customer (who has a terminal case of "not thought of here" desease") so we end up having a lot of red-lined prints from our customer's engineering dept. to "get by for now" (read indefinitely)

the fun part for us is our 3 biggest customers are supplying the same end user. we make the same parts for each of them so the end customer gets the parts from 3 vendors who all get their parts from us.

Other reasons why prints can't get changed: Governing board approved design (FDA), Reliability analysis would have to be completely re-done (Space), change will put all produced/on-the-field product in question (molded product)...

I worked for a company who internally-designed product based upon basic customer parameters, so we had an internal design engineering team of 1 supervisor and 5 engineers. They were all buddy buddy dinosaurs. All had all been there 20+ years, and NONE "believed in GD&T". They literally put a generic note on each drawing 'GD&T per ASME Y14.5M', but no year. I asked what revision year GD&T applies to our prints and they said, "Well the current one, I guess." Facepalm. Some prints were created as far back as the 1970's so design intent would totally change if judged by today's gd&t (mmc bonus implied in 73 release).

Datums would be out of order, missing, etc. it was a mess. They would produce drawings that compounded cost so much, that we had some parts with 100% dimensional on all parts made (thousands per day), even though customer never had a single quality complaint.
