True Leaders Are Also Managers; Harvard Business Review, 8/11/10

Robert I. Sutton, Harvard Business Review; True Leaders Are Also Managers:

"I am not rejecting the distinction between leadership and management, but I am saying that the best leaders do something that might properly be called a mix of leadership and management. At a minimum, they lead in a way that constantly takes into account the importance of management. Meanwhile, the worst senior executives use the distinction between leadership and management as an excuse to avoid the details they really have to master to see the big picture and select the right strategies.

Therefore, harking back to the Bennis theorem I quoted above, let me propose a corollary: To do the right thing, a leader needs to understand what it takes to do things right, and to make sure they actually get done."

When we glorify leadership too much, and management too little, there is great risk of failing to act on this obvious but powerful message."
