Think about how much our world has changed over the past decade. Innovation has transformed the way we work, live, communicate, and play. The future promises even more change. Innovation might seem to be a force beyond our control, but it doesn't have to be, as I show in my book, "The Little Black Book of Innovation " [Harvard Business Review Press, $25.00]. Innovation - something different that has impact - is a discipline. It can be mastered; it can be managed. Decades of academic research and practical field work have highlighted simple steps that allow anyone to more reliably spot and seize opportunities for innovation.
