At Microsoft many years ago, they used to put a lot of product design work on PMs (who didn't have the training or time / bandwidth to do that well). I think this was the Ballmer era...
Personally, I think a PM that doesn't have training / skills to do product design work is a glorified note-taker.
I don't necessarily mean the implementation skills of "making screens", but arguably that skill is the easiest to obtain. Otherwise you end up with a weird division of labor, where the PM actually does all the creative design work and the designer is an implementation monkey, which I don't know any designers that are good that would want that job
Yep exactly what happened at Microsoft, hence Vista and all the other products that spilled out of Ballmer's tenure like trash out of an overturned dump truck
