The global economy-the flattened world-demands a new type of leadership: collective and collaborative, where the solutions and vision are co-created by the team. Yet the practical application of collective leadership remains a mystery to many practicing executives and managers. The Leaderful Fieldbook helps change agents-from managers and trainers to consultants and coaches-create the conditions for transitioning from conventional to more collaborative forms of practice. Everyone is capable of participating in leadership, and not just sequentially, but collectively and concurrently-that is, all together and at the same time. The Leaderful Fieldbook presents a fresh and successful approach to leadership development across organizations.
