I received my MBA from OU over 40 years ago but one of things was that discussed back in the day was the life cycle of a manager, the initial phase or learning stage, the highly productive stage, the Plateau stage and the declining stage. With the realization that every manger is different but in the end most will go through these four stages, the trick is to move the manager before he hits the Plateau stage to either a more challenging job (or out of the organization) and to avoid at all costs letting a manger get aphetic (declining stage) where his performance will hurt the organization.
