PETER PRINCIPLE

An observation that in an organizational hierarchy, every employee will rise or get promoted to his or her level of incompetence. The Peter Principle is based on the notion that employees will get promoted as long as they are competent, but at some point will fail to get promoted beyond a certain job because it has become too challenging for them. Employees rise to their level of incompetence and stay there. Over time, every position in the hierarchy will be filled by someone who is not competent enough to carry out his or her new duties.
