The better a man is, the more mistakes he will make, for the more new things he will try. I would never promote to a top-level job a man who was not making mistakes...otherwise he is sure to be mediocre.
Peter DruckerThere is no reason to believe that the people who staff the managerial and professional positions in our service institutions are any less qualified, any less competent or honest, or any less hard-working than the men who manage businesses. Conversely, there is no reason to believe that business managers, put in control of service institutions, would do better than the 'bureaucrats'. Indeed, we know that they immediately become bureaucrats themselves.
