Laurence J. Peter, in his best selling book, The Peter Principle, argued that individuals are promoted to their level of incompetence. He saw this progression as being typified by successive promotion from success at lower levels until the individual gets to a point where he is described as inefficient. The Peter Principle has been accepted because it described clearly and vividly the experience of individuals and of organisations, but we believe that whilst it is descriptively correct, it is only partially true in its conclusions.
