The Peter Principle is a special case of a ubiquitous observation: Anything that works will be used in progressively more challenging applications until it fails.
Applied to humans, the selection of a candidate for a position is based on their performance in their current role rather than on their abilities relevant to the intended role.
- The Peter Principle is an observation that the tendency in most organizational hierarchies, such as that of a corporation, is for every employee to rise in the hierarchy through promotion until they reach a level of respective incompetence.
- According to the Peter Principle, every position in a given hierarchy will eventually be filled by employees who are incompetent to fulfill the job duties of their respective positions.
- A possible solution to the problem posed by the Peter Principle is for companies to provide adequate skill training for employees receiving a promotion, and to ensure the training is appropriate for the position to which they have been promoted.
