A designer doesn't have to "dictate," it is the data sheet or associated
industry standards that "dictate." The data sheet that is approved by the
component engineer, board build, mechanical engineering, and purchasing.
That's the point, and THAT is a team attitude, where everybody on the team
counts equally and the junior engineer learns how not to be a pouting brat
kicking the floor and whining "I won't do it and you can't make me."
I agree: It's not the way it's done at many companies.
Just the world class ones.
Everybody have a great weekend.

George:
You seem to have missed the point.
The question is and will always be, "Who can make a change in the
circuit (pin numbers)" and the answer always remains, "The
Responsible Engineer."
A designer asks, A designer never 'dictates.'
It's called being 'on board' with the team! (AND the Company.)
Four hundred pages of examples omitted for brevity!
