The Innovator's Dilemma: The Revolutionary Book That Will Change the Way You Do Business Paperback – October 4, 2011

The Innovator’s Dilemma is an interesting work written by Clayton M. Christensen in 1997. The book seeks to explain why certain businesses are successful in their ventures and why other firms fail in response to new technologies. Christensen tries to explain throughout the book why some firms, when new technologies enter the market, fail either because they adapt the new technology or not. The author initially believes that new technologies are constantly emerging and all businesses must continually adapt to stay relevant. However, this proves to be false as in his studies not all firms that ignored the new technology failed while not all firms that adapted the new technology succeeded. This is the fundamental dilemma in the book, and Christensen’s main purpose is to figure out a recipe for managers to follow to stay successful when disruptive technologies enter the market. Most of the book revolves around the study of the disk drive market since they were first developed in the 1950’s. The disk drive industry was important because technology was rapidly advancing and smaller drives were being released within a few years of each other. Many of the established firms often chose not to invest in the next smaller disk drive because they did not have enough memory to meet their standards. However, emerging firms would find new markets for the use of smaller drives and also find ways to make them more powerful, eventually drive the existing firms out of business. Christensen eventually concludes that successful businesses often collapse, despite having good managers, because they fail to find the new markets for disruptive technologies while instead supplying current customers with what they currently need.
The goal of the book is to educate people in the business world about how new technologies affect firms and to provide a new way of thinking about disruptive technologies. The end of the piece brings the conclusion that leading firms almost always have set technologies that work well for their current customers, choosing not to invest in new technologies because what they are currently doing is working, current customers do not want change. That is, until new technologies grow to be superior than their predecessors. Christensen does a fantastic job in making his point clear as he provides a plethora of studies across different markets to support his claims. The first half of the book is essentially a detailed history of the disk drive industry that has multiple examples of different firms both choosing to invest in smaller drives and continuing to use their already established, larger drives. He uses this information to create hypothesis’ about why these firms made their decisions and whether it lead them to success or not. Essentially, the author’s process in writing the book is to look at different industries that had disruptive technologies and discover what trends lead to success and what trends lead to failure. He spends a lot of time focusing on a single industry, the disk drive. However, he does bring up several other markets including the mechanical excavator, steel, computer, and discount retailer industries. This variety of different scopes enhances his argument, especially since he sees similar trends across all of these different markets. Many of his examples include established firms choosing not to adopt new technologies because it does not fit their current business motives, but then later being replaced by firms that dared to find new markets for the new technology. His claims are definitely unbiased as all of his conclusions are drawn from the hard evidence that he compiles and delivers to the reader throughout the book about the different firms in those industries. It is almost impossible to disagree with his conclusion since all of his evidence accurately backs up his claims.
Personally, I enjoyed reading the book but mostly because it appeals to my interests. As a young business major, the book is intended for me to read and may directly pertain to my own future. However, this book would be challenging to read for the average person that is not interested in business. The book is confusing at some times and is clearly designed for educated readers with a basic understanding of the business world. I would say that the book is a must-read for managers of a company that may be facing disruptive technologies in their industry as it does provide direct advice for people of that demographic. It is a book that I would certainly recommend to my peers within my major.
Christensen does a decent job in making the book engaging. Some of the chapters where he is providing data are dry and confusing, but he does always provide a summary at the end of chapters to keep the reader focused. A lot of the book is also repetitive in regards to the disk drive industry and the author reiterating his claims about disruptive technologies. Nonetheless, the book is overall definitely a success for its purpose. There is plenty of evidence throughout the book that prove his claims in real-world situations. His main ideas about why firms choose to serve current customers with current technology rather than try to force new technologies on customers also makes logical sense, given the customer-centric market that is present in today’s society. His complex conclusion that disruptive technologies succeed only when they find a market that does not currently exist is confusing, but is definitely supported with his evidence.
In conclusion, the book is a great read for those looking to advance their knowledge in the business world and think about topics that are not usually discussed. The author’s conclusions are creative and complex, but are backed up with hard evidence throughout the piece. The insights and advice brought up by Christensen are useful knowledge to any person studying business and the impact of emerging technologies. This is a book that I will definitely keep in mind in the future and I will recommend to others.

This book used to be required reading, but it is woefully outdated and has lost relevance. The central themes are still sound but the stale references to companies and industries from the 80s/90s and nods to then-'emerging' technologies and services that are now old school is all just distracting and, to be honest, boring. Since this book arrived and wowed the progressive thinkers of 20+ years ago we have all gone through Lean Start-ups, self-disruption, Red-Blue Ocean, etc. - this is all Innovation 101 now. His hardware and manufacturing-centric world has been replaced with software, content, and services - and, frankly, the models have changed a bit. I was initially encouraged to see the book has been reprinted in 2016 but it seems like they updated little to nothing. It is a shame - the core lessons are still valid but his delivery has lost context in a much-evolved world.

This is not a nail-biter, nor does the author do a good job of keeping you interested. It is dry and tedious. So why do I give it five stars?

Clayton M. Christensen has recognized a major problem in business, that of tapping into disruptive innovation in a successful way, and tells us how to avoid the pitfalls and to leverage it to the advantage of the company. He has plenty of insight and is a big-picture thinker. The book is enlightening and is required reading for any business person that is in a field where innovation is important. By the way, this is a business book, not an inventor's book - as it is not about innovation itself, but is about applying that innovation to your business.

Once you get through the first couple of chapters you will realize how important this book can be and you will want to read the rest of it.

I've been involved in innovation most of my career, and now wish I'd read this book much earlier. The simple but powerful thesis of the book is backed up by data and case studies from disparate industries. Like many business books it is a bit repetitive at the end. And my Kindle edition suffered from poor editing in the first few sections although those problems disappeared later on. But the ideas and usefulness are five stars.
