book "The Peter Principle: Why Things Always Go Wrong"

"The Peter Principle: Why Things Always Go Wrong," written by Dr. Laurence J. Peter and Raymond Hull, posits that in a hierarchical organization, individuals are often promoted based on their performance in their current role rather than their ability to perform in the new position. As a result, they may eventually be promoted to a level where they are incompetent, leading to inefficiency and failure. This principle illustrates how systems can break down when people are not well-suited for their roles, highlighting the disconnect between skills and responsibilities in organizational structures.
