Book excerpt: Management experts discuss the innovation challenges that lie ahead, building on Clayton Christensen's famous theory of "disruptive innovation." Clayton Christensen's groundbreaking theory of "disruptive innovation" has proven to be one of the most influential management ideas of the last several decades. In this book, business and management experts--many of them Christensen's colleagues and former students--discuss the innovation challenges that lie ahead. Building on Christensen's work, they offer companies a guide for navigating a new world of disruption--a future in which artificial intelligence is a business tool, the speed of innovation increases dramatically, and capital is more easily accessible. The book also includes one of the last interviews with Christensen before his death in January 2020.
