The greatest managers in the world seem to have little in common. They differ in sex, age, and race. They employ vastly different styles and focus on different goals. Yet despite their differences, great managers share one common trait: They do not hesitate to break virtually every rule held sacred by conventional wisdom. They do not believe that, with enough training, a person can achieve anything he sets his mind to. They do not try to help people overcome their weaknesses. They consistently disregard the golden rule. This amazing book explains why.Gallup presents the remarkable findings of its massive in-depth study of great managers across a wide variety of situations. Some were in leadership positions. Others were front-line supervisors. Some were in Fortune 500 companies; others were key players in small entrepreneurial companies. Whatever their situations, the managers who ultimately became the focus of Gallup's research were invariably those who excelled at turning each employee's talent into performance.There are vital performance and career lessons here for managers at every level, and, best of all, the book shows you how to apply them to your own situation.
