The work looks at the results of the Peter Principle, which predicts that people are promoted to the level of their incompetence. Their skill gets them a series of job advances until they are ultimately promoted one level higher than abilities warrant. This results in an organization promoting itself into declining performance.
The Italian researchers ran computational models and concluded that ”counterintuitively, that in order to avoid such an (Peter Principle) effect the best ways for improving the efficiency of a given organization are either to promote each time an agent at random or to promote randomly the best and the worst members in terms of competence.”
