“Delegation is the dynamics of management; it is the process a manager follows in dividing the work assigned to him so that he performs that part which only he, because of his unique organizational placement, can perform effectively, and so that he can get others to help him with what remains. How can he best share his burden? First, he must entrust to others the performance of part of the work he would otherwise have to do himself; secondly, he must provide a means of checking up on the work that is done for him to ensure that it is done as he wishes.”
