I will give this four stars ... but I am probably a bit high with that and Goodreads does not encourage or permit fractional ratings. The book is topical and sharply written, but it is also a bit odd, in that it is both too long, with lots of repetition, rehash, and digression, while at the same time being too short, in that many of the key caveats and limitations to what is presented are not spelled out.
You hear Christensen’s name bandied out a lot, to the point where you would expect there to be a trademark associated with using the phrase “disruptive innovation”. What does that mean? If you get to that question, you have reached a critical question to ask about this iteration of Christensen’s disruption sage in general and this version of it in particular.
The general idea is fairly straightforward and even a bit alluring. Innovation comes to established industries in at least two ways: sustaining innovation and disruptive innovation. Sustaining innovation is what happens to reinforce and improve the existing ways of doing business iu the industry — better machines and techniques that help us do what we have already been doing but better than before. Disruptive innovation provides a qualitatively different way of getting key tasks and jobs done that have the promise of lower costs and high quality. When these show up initially, they are embodied in simple applications but are likely inferior to the dominant approaches in an industry. As a result, firms in an industry fail to adopt and advocates of the disruption go elsewhere and gain valuable experience in the innovation. The rejected disruption comes back at higher volume and quality and then dominates the industry, but the purveyors of established practices out in the cold when they prove unable to adapt. Disruption leads to progress and the key is for industry incumbents to embrace disruption, even at the cost of potentially cannibalizing one’s current business. This was sort of the argument that Christensen used for disk drives and backhoes in his first book on this - the Innovator’s Dilemma. And the rest, so they say, is history!
So, how does this play out for health care? Are hospital and physician services akin to the work of personal computers or digging machines? Hmmm... Yes, sort of, but the argument morphs a bit when the move to health care is made, I think.
The idea for health care is that of a complex business with at least three different types of business models. The first in Intuitive Medicine, which is characterized by the expert work of highly trained physicians and their staff in diagnosing serious medical problems in patients and then crafting, through trial and error, the best responses for the patient. This is expert intensive, uncertain in outcomes, time consuming, and very expensive via fee for service billing. The second type of business embedded in health care is Empirical Medicine in which, once a diagnosis has been standardized regarding a health ailment, value can be added through a fairly standardized set of processes that are generally successful in addressing a patient’s problem. Newborn deliveries, cardiac catheterization processes, and hip replacement would be examples of such processes. They still require expert can but have sufficient volumes that they can be managed and have their outcomes assessed. The third type of medicine is embodied in expert networks that enable patients to managing continuing chronic conditions through combinations of medication, behavioral treatments, and periodic consultations with physicians, nurse practitioners, or other health professional.
The point of this book is to argue that the way to improve health care and health care patient outcomes is through innovations that move as much of the health care business as possible and necessary away from fee for service intuitive care in “solution shop” hospitals - unless of course you really need that - and into well understood value added processes and extended networks.
The book is long and detailed. Christensen and his co-authors explain the arguments in some depth and frequently repeat them - in case you are unable to look back in the book or did not get it the first time around. There are lots of examples and numerous imposing charts and graphs. The tone of the book is very upbeat and encouraging — the future is here, we should all get ready!
What is not to like? Well, Christensen tells a mean story, but most of the points in the book could easily have been made without reference to Christensen’s theory, such as it may be. I do not really need him to tell me that a lot has changed in the practice of health care over the past twenty five years. I already knew that the industry had changed a lot, had been shaken up, — oh yes had been disruptied. If a reader is not familiar with the industry, then the book is informative and potentially even helpful.
But what about the theory? To start with, it changes with each iteration. There are different nuances to different types of innovation, disruptive or otherwise. If it is a theory rather than a story, it would have helped for there to be predictions and there are not that many of those that I could find. More to the point, Christensen himself has written more recently about how his expectations for disruptions in health care have not come about as he expected. Progress towards the innovations he has focused on has been slower than first expected. We still have to go to hospitals. Mass consumer clinics through your local drug store chain or Wal-Mart have not developed as planned, although there has been some progress. Very few works like this are completely off base, and Christensen has a lot to say that is worth considering.
What troubles me more is what is not emphasized. There are lots of problems in health care that do not boil down to a need for disruptive innovation. For example, in many areas there is rampant over-pricing, in which providers make use of their local market power and the unequal distributions to charges high multiples for products and services. That is not innovation as much as it is the workings of capitalism in some very imperfect market situations. Some recent books by Marty Makary bring this out in considerable detail. More generally, it seems clear that many decision makers in health care do not wish to innovate but rather like their market positions.
Overall, if you give Christensen the full benefit of the doubt here, his approach is more of a bottom up approach in which local actors and innovator/entrepreneurs can by their choice change the health care business. At the same time, however, he often notes how unless the overall context of the health care system is changed, it will not be possible for innovators to really change that much. So where will the impetus for system change come from? I do not believe it will bubble up from below but it is not clear who in government, business, or the medical establishment will lead the charge for change. The book focuses on large employers as a potential source of change but even in the book, the long term potential for this is limited.
So ... it sounds like a good idea and the story rings true in some circumstances, but it “you cannot get there from here” then what conclusions are we to draw about the argument? It is a good story that sells a lot of books and executive education classes at the Harvard Business School, but what does it really mean for practice? If the overall solution is not feasible, that is not a good recommendation.
Stylistically, this book reads like a collection of chapters and presentations that have been knitted together into a book. That is the only way I can make sense out of the extensive repetition of arguments that occurs throughout the book. It makes a long book even longer. Some of the digressions are also not helpful. The argument is frequently made that health care is analogous to some other industry. I do not find such analogical reasoning helpful. Perhaps there are some overall similarities, but industries as discussed in this book are extraordinarily complex in their details and none of the surface comparisons in the book was particularly informative or helpful.
