"Cohen and Bradford give both leaders and followers the tangible tools they need to create high performance. Their transformational leadership system is both sophisticated enough to capture the realities of life in today's organizations and simple enough to be immediately useful to managers in any part of the world. This book will be read, re-read, and sent to bosses everywhere."--Rosabeth Moss Kanter, author of Rosabeth Moss Kanter on the Frontiers of Management "In Power Up, Bradford and Cohen not only convincingly argue the benefits of leading by building a shared responsibility team, they also describe in detail how to do it. Loaded with many powerful examples and detailed cases that bring their concepts to life, this book will inspire any leader."--Jerry Porras, coauthor of Built to Last and Lane Professor of Organizational Behavior and Change, Stanford Business School "Traditional assumptions about the roles of managers and subordinates are barriers to long-range success ...Bradford and Cohen provide practical insights into how to transform the leadership systems of modern business organizations, and these insights should be shared among employees and managers at all levels."
