Describe the Peter Principle. What are the arguments against it?

What will be an ideal response?

The Peter Principle, named after Lawrence J. Peter, co-author of the popular book by that title, states that employees tend to be promoted to the level of their incompetence. In other words, employees grow and develop to an upper maximum level of competence beyond which they do not grow. They then are promoted to a position of higher authority but bring with them a level of competence on which they do not improve. This is true from the perspective of the technical abilities required for work to be done. What the Peter Principle ignores is that if only employees who had fully developed all the skills needed to be successful in all dimensions of management and leadership were promoted, then we would have few managers and leaders available. Management and leadership are learned with experience. Many managers are promoted and then grow into their new roles with experience. They may be deficient in some skills, but have other well-developed valuable skills.
