The final test of leadership is to leave behind men and women with the conviction, commitment and competency to carry on ... and this can be accomplished through delegation. Delegation is the on-going process by which a leader assigns additional tasks (i.e., responsibilities and authority) to a subordinate in such a way that there is acceptance of responsibility for the assigned tasks.
If this manager continues not to delegate, he may be taking a shortcut to the cemetery because the work will be too big and heavy for him to bear alone. Meanwhile, his subordinates will become bored and lose enthusiasm in their jobs.
Delegating work works, provided the one delegating works, too. Robert Half
The best executive is one who has sense enough to pick good people to do what he wants done, and self-restraint enough to keep from meddling with them while they do it. President Roosevelt
