Since the publication of Clay Christensen's The Innovators' Dilemma nearly two decades ago, Michael Tushman PhD '76 and his colleague Charles O'Reilly III have studied successful firms, large and small, that didn't exactly fit the new norm of disrutpive innovation. The result of this study is Lead and Disrupt: How to Solve the Innovator's Dilemma. In this interview, Tushman discusses his new book, a well-researched corrective for Christensen's formula for success in business.
