This book is designed to help leaders apply whole leadership lessons to the fundamental leadership dilemmas that keep leaders awake at night. The book explores how leaders developed their capacities for leadership and what they believe will be the key ways to prepare other leaders to meet these challenges in the future. Each section describes the challenges and includes specific tips for managing the challenges based on the interviews and research. The models are based on the authors' personal observations of the executives they have taught and coached over the last three years through Oliver Wyman's Delta Executive Learning Center, in addition to interviews with 20 current CEOs including William Weldon, CEO of Johnson & Johnson; Gregg Steinhoffe, CEO of Target; Mark Parker, CEO of Nike, and many others.
