When times are hard, leadership makes the greatest difference. So says the evidence. This book shows how to make the kind of difference that all organizations, both public and private sector, want and need. Early chapters show the powerful effect leadership can have on organizations; subsequent chapters present new ideas that are elegantly simple, conceptually coherent and radically different, based on the best research in the field. The ideas in this book have also been tested in major multinational organizations over recent years. The aim is to provide leaders and those who work with them with a practical guide to how to increase the effectiveness of leadership in any organization.
