It has several advantages over learning from one's own, but it requires the discipline to identify faults and recognize that one might be duplicating them.

Mistakes can fall crudely fall into five categories:
1. Errors of omission (failure to act or communicate)
2. Errors of commission (doing things you ought not to have done)
3. Qualitative errors (doing the right thing inadequately or by the wrong method)
4. Errors of timing (doing the right thing too early or too late)
5. Credibility errors (doing the right thing, at the right time, but in such a way as to irritate everyone or discredit the action)
Every one of these can teach us a lesson. All about you, at all levels of contact, people are continually reminding you of the human failings which make good people bad managers.
