In today's world, it's incumbents against insurgents, the old guard versus the vanguard. Companies must reinvent themselves and their industries--not just in times of crisis, but continually. Drawing on the experiences of Charles Schwab, Cisco, Virgin Atlantic, Disney, and other world-class companies, Gary Hamel explains the underlying principles of radical innovation, explores where revolutionary new business concepts come from, and identifies the key design criteria for building companies that are activist-friendly. He shows how to avoid becoming a "one-vision wonder" and instead harness the imagination of every employee, develop new financial measures that focus on creating new wealth, and generate vibrant internal markets for ideas, capital, and talent.
