Peter Principle
It holds that in a hierarchy, members are promoted so long as they work competently. Sooner or later they are promoted to a position at which they are no longer competent (their "level of incompetence"), and there they remain, being unable to earn further promotions. Peter's Corollary states that "in time, every post tends to be occupied by an employee who is incompetent to carry out his duties" and adds that "work is accomplished by those employees who have not yet reached their level of incompetence".

In an organizational structure, the Peter Principle's practical application allows assessment of the potential of an employee for a promotion based on performance in the current job; i.e., members of a hierarchical organization eventually are promoted to their highest level of competence, after which further promotion raises them to incompetence. That level is the employee's "level of incompetence" where the employee has no chance of further promotion, thus reaching his or her career's ceiling in an organization.

The employee's incompetence is not necessarily exposed as a result of the higher-ranking position being more difficult — simply, that job is different from the job in which the employee previously excelled, and thus requires different work skills, which the employee usually does not possess. For example, a factory worker's excellence in his job can earn him promotion to manager, at which point the skills that earned him his promotion no longer apply to his job.
