" In our view, leadership is always a relationship, and truly successful leadership thrives in a group culture of high openness and high trust. Leadership and culture can be seen as two sides of the same coin, and culture is quintessentially a group phenomenon. Though this book focuses on a new model of leadership, it is equally a book about culture and group dynamics. "
