Peter principle

The linked article is about the Peter principle, which refers to the observation that people tend to reach a level of incompetence in a hierarchy because they are promoted based on their success in previous jobs until they reach a position that requires skills they do not possess. They then remain in that position or on "Peter's plateau." Several studies have interpreted the Peter principle, and some companies have developed policies to contend with its effects. The Dilbert principle is another similar concept developed by Scott Adams.
