“Executives will have to learn what the effective department head of a university or the successful conductor of the symphony orchestra have long known: The key to greatness is to look for people’s potential and spend time developing it.
To build an outstanding university department requires spending time with the promising young postdocs and assistant professors until they excel in their work.
To build a world-class orchestra requires rehearsing the same passage in the symphony again and again until the first clarinet plays it the way the conductor hears it. […]
Similarly, leaders in knowledge-based businesses must spend time with promising professionals. Get to know them and be known by them; mentor them and listen to them; challenge them and encourage them.”
– Peter F. Drucker in the Harvard Business Review 2002
