Maybe a peer review would be the wrong way, but when a crew chief gets run off several crews for the same problems with different crews, it would be nice to have some sort system in place for the crew to clip his wings. Of course that same type of crew chief is most times loved by management, so they won't do the clipping.You want peer reviews? Interesting concept, but that runs the danger of becoming a modified popularity contest.
Oh, wait, you already have experience with popularity contests. It's called local elections...
