" In successful transformations, the president, division general manager, or department head plus another five, fifteen, or fifty people with a commitment to improved performance pull together as a team. This group rarely includes all of the most senior people because some of them just won’t buy in, at least at first. But in the most successful cases, the coalition is always powerful—in terms of formal titles, information and expertise, reputations and relationships, and the capacity for leadership. Individuals alone, no matter how competent or charismatic, never have all the assets needed to overcome tradition and inertia except in very small organizations. Weak committees are usually even less effective. "
