An unsuccessful manager blames failure on his obligations; the effective manager turns them to his own advantage. A speech is a chance to lobby...a visit to an important customer a chance to extract trade information.
Henry MintzbergIf you ask managers what they do, they will most likely tell you that they plan, organise, co-ordinate and control. Then watch what they do. Don't be surprised if you can't relate what you see to those four words.
