It is a frustrating process and it goes both ways.

You need to give feedback correctly both in how and why.

The developers learn to accept the feedback, but it will be a more painful experience for them more because nobody likes their work critiqued. (This is something that I've found trained artists are very good at, as they've been giving and receiving critiques from both peers and instructors from the time they were freshmen)
