In our teaching we have so exalted the virtues of data-driven decision making that in many ways we condemn managers only to be able to take action after the data is clear and the game is over.

Clayton ChristensenYear after year after year, people write books about managing innovation or about leadership, for example, without ever going through the pain of saying, "This kind of leadership will cause this result in these circumstances and a very different result in those circumstances." This is academic malpractice of the worst kind.
