Properly evaluating other peoples' work is very hard. The comparative evaluation of that work with other people's work is even harder. But in an optimal system, such evaluation is essential. This is one of the fundamental problems of leadership--and universities suck at it.

But teaching gets shunted aside, because nobody is really taking the time to carefully evaluate the quality of the teaching. Prospective students ought to be able to make informed decisions about their prospective teachers.
The real resources need to be put into hiring and retaining people who will fairly evaluate great work. Those are your most important people.
