I believe that criticism is one of the lowest level skills–because anyone can do it. And criticism has little value for a supervisor or manager whose job it is to improve the performance and value of subordinates. The fact that performance reviews are often built around criticism is a clear sign that the manager’s skills are in need of improvement. People who have a performance difficulty need help to identify and correct the cause of weak performance. It can be a skill deficiency, a process problem, a lack of motivation, whatever. In any case, what’s needed is a system for coaching not criticism.
