Traditional approaches to leadership development focus on a small number of individuals at the top. However, in today's world of constant change and decentralized decision-making, organizations need effective leaders at all levels of their organizations. That requires a much broader and deeper pool of leadership talent, and most organizations fall far short of what they need.Leadership at Scale defines a new approach. In it, top experts at McKinsey, the world's number one leadership factory, expose the secrets of how to drive leadership development that reaches the entire organization, adapts to diverse contexts and achieves impact at scale. Grounded in extensive research and the global experience of +25 leadership experts and illustrated with a fictional step-by-step case with numerous real-life examples, this book provides leaders with the systematic and fact-based approach they need to unlock organizational performance through leadership effectiveness.
