The definitive books on one of the most influential business ideas of our time, disruptive innovation. His work is cited by the world's best-known thought leaders, from Steve Jobs to Malcolm Gladwell. In these classic bestsellers, innovation expert Clayton Christensen shows how even the most outstanding companies can do everything right—yet still lost market leadership. In The Innovator's Dilemma, Christensen presents his theory of disruptive innovation and explains that, no matter the industry, a successful company with established products will get pushed aside unless managers know how and when to abandon traditional business practices. In The Innovator's Solution, Christensen and his coauthor, Michael Raynor, expand on the idea of disruption, showing how companies can and should become disruptors themselves. Sharp, cogent, and provocative, these are the two books that no manager, leader, or entrepreneur should be without.
