The research indicates that leaders with the best results do not rely on only one leadership style; they use most of them in a given week—seamlessly and in different measure—depending on the business situation. Imagine the styles, then, as the array of clubs in a golf pro’s bag. Over the course of a game, the pro picks and chooses clubs based on the demands of the shot. Sometimes he has to ponder his selection, but usually it is automatic. The pro senses the challenge ahead, swiftly pulls out the right tool, and elegantly puts it to work. That’s how high-impact leaders operate, too.
