I have been in the same situation as the OP and in my own experience this wouldn't have helped, though that is not to say your advice won't work in this situation. In my situation the issue wasn't that they hadn't been given the message in a constructive way, it was that they were incapable of receiving it, or rather their own needs and instincts meant they weren't really aware of the request. It was like noise around them. The same thing that stopped them just learning and figuring out the technical issues was the same thing that meant they couldn't be receptive to friendly constructive suggestions in that direction. To OP if your experience is like mine the situation was only fixed by the person not working in the same area of the business. Hopefully you are able to navigate to a successful solution!
