In this classic bestseller--one of the most influential business books of all time--innovation expert Clayton Christensen shows how even the most outstanding companies can do everything right--yet still lose market leadership. Christensen explains why most companies miss out on new waves of innovation. No matter the industry, he says, a successful company with established products will get pushed aside unless managers know how and when to abandon traditional business practices. Offering both successes and failures from leading companies as a guide, The Innovator's Dilemma gives you a set of rules for capitalizing on the phenomenon of disruptive innovation. Part Two--comprising chapters 5 through 10-suggests that although the solution to disruptive technologies cannot be found in the standard tool kit of good management, there are sensible ways to deal effectively with this challenge. Chapters 9 proposes that the phenomenon in which product performance overshoots market demands is the primary mechanism driving shifts in the phases of the product life cycle. It also highlights how and why accounting software and insulin businesses fell victim to disruption.
