This is a summary of Marcus Buckingham's First Break All the Rules: What the World's Greatest Managers Do Differently

With vital performance and career lessons and ideas for how to apply them, it is a must-listen for managers at every level. 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. And, yes, they even play favorites.

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. In today's tight labor markets, companies compete to find and keep the best employees, using pay, benefits, promotions, and training. But these well-intentioned efforts often miss the mark. The front-line manager is the key to attracting and retaining talented employees. No matter how generous its pay or how renowned its training, the company that lacks great front-line managers will suffer.
