The Peter principle is a concept in management theory formulated by Laurence J. Peter in which the selection of a candidate for a position is based on the candidate's performance in their current role, rather than on abilities relevant to the intended role. Thus, employees only stop being promoted once they can no longer perform effectively, and "managers rise to the level of their incompetence."
In an organizational structure, assessing an employee's potential for a promotion is often based on their performance in the current job. This eventually results in their being promoted to their highest level of competence and potentially then to a role in which they are not competent, referred to as their "
level of incompetence". The employee has no chance of further promotion, thus reaching their career's ceiling in an organization.
So it may be that many large hierarchical type organisations are run by incompetents!
