Are you struggling with your maintenance management and supervisory staff who are technically competent but lacking managerial skills?

"Every employee tends to rise to his/her level of incompetence".

The Peter Principle is a concept in management developed by Laurence J. Peter, which observes that people in a hierarchy tend to rise to their "level of incompetence": employees are promoted based on their success in previous jobs until they reach a level at which they are no longer competent, as skills in one job do not necessarily translate to another.
