User:Rodd Wagner/12: The Elements of Great Managing

12: The Elements of Great Managing is a New York Times bestseller written by Rodd Wagner and James K. Harter. It is the sequel to First, Break All the Rules, although the first book was written by Marcus Buckingham and Curt Coffman. Both books are based on The Gallup Organization's research on employee engagement and database of employee opinions. 12 tells the story of a dozen managers selected from Gallup's global database of 10 million interviews with managers and employees. It also describes the psychology behind each of the 12 questions the company asks in its employee surveys.
