The Innovator's Guide to GrowthPutting Disruptive Innovation to WorkScott D. Anthony, Mark W. Johnson, Joseph V. Sinfeld and Elizabeth J. AltmanHarvard Business Press, $35, £19.99Ten years ago, Clayton Christensen's book, The Innovator's Dilemma, was a bestseller. Christensen showed how innovation could become a form of trap. Companies invest large amounts of time and money in innovation but then lack the ability to make their innovations viable commercially. The investment never yields a return. Meanwhile, other less innovative companies figure out how to capitalise评估，利用 on the opportunity and go on to make a fortune, leaving the original innovator languishing.

This new book, The Innovator's Guide to Growth, is not by Christensen but his stamp is all over it. He wrote the foreword, and three of the four authors are consultants with Innosight, the consulting firm he founded, while the fourth is an executive at Motorola (NYSE:MOT) . It can be assumed that the writers have his approval.

The book is meant to pick up where The Innovator's Dilemma left off. "The odds remain stacked against the growth-seeking innovator," the authors claim, "whether he or she is an entrepreneur or a manager inside a deep-pocketed incumbent. Most start-up companies...fail. Most internal innovation effort delivers disappointing returns."
