Thanks alot!... Indeed, incompetence is recking and can affect productivity and growth especially when it's being exhibited by someone who's suppose to be a role model to subordinates as well as direct, coordinate and plan the activities in an establishment.@Chris Jo very insightful comment. Some incompetent manager don't exhibit this signs early enough until their toxic character and lack of managerial skills affect the company. Some are good faking a good manager but the level of productivity has been one of the most effective ways to detect an incompetent manager.
