Heenan and Bennis believe we must look beyond the Bill Gateses of the world to understand what makes an organization excel. Written for CEOs, managers, and anyone else interested in modern organizations, this is the first comprehensive study of co-leaders and their often quiet power. Exhaustively researched and illustrated with memorable anecdotes and lively stories, Co-Leaders examines a dozen great partners such as Steve Ballmer of Microsoft, Bob Lutz of Chrysler, Bill Guthridge of the University of North Carolina basketball team, and Anne Sullivan Macy, Helen Keller's teacher.

The changing nature of corporate leadership has seen the emergence of a new Silicon Valley model of success, where boss and subordinate seem more like peers, with the spotlight on great partnerships. Talent, not title, is the source of power at a growing number of hot high-tech companies. In these collegial, nonhierarchical organizations, today's deputy can become tomorrow's CEO simply by taking his or her breakthrough idea and walking out the door. Good ideas belong, initially at least, to the people who have them, not to the company and not to the boss, which is why this new egalitarianism isn't just a matter of style - it's a question of survival. Co-leaders understand both the executive and subordinate experience, making them better adapted to the needs of the new millennium, where men and women who can command and follow will prove to be the greatest assets of any organization.
