By Tom Rath and Barry Conchie. Nearly a decade ago, Gallup unveiled the results of a landmark 30-year research project that ignited a global conversation on the topic of strengths. In recent years, while continuing to learn more about strengths, Gallup scientists have also been examining decades of data on the topic of leadership. They studied more than 1 million work teams, conducted more than 20,000 in-depth interviews with leaders, and even interviewed more than 10,000 followers around the world to ask exactly why they followed the most important leader in their life. With its novel research and actionable ideas, Strengths Based Leadership will give you a new road map for leading people toward a better future. Gallup Press (2009), English, Paperback: 216 pages.
