So, the information, the ideas would make this a five star book. It's a way of thinking that helps ward off obsolescence, a way of thinking that gets people to understand where future disruption may come from. The whole idea: that good management (like, truely good) eventually leads to poor decisions is fascinating.

The example: If current customers demand "faster horsers" companies rightly put their energy into faster horses. What the customer says and wants isn't necessarily what's good for the company. Meaning: everyone wants something and they lie about their wants.
This book is about how to differentiate between "Sustataining innovation" (more megabytes) and "disruptive innovation" (a different form factor, a different approach.)

This would score very poorly on the "Flesch Reading Scale," and I found the writing to be opaque at times - it's easy to write sentences with multiple qualifiers . It's more difficult to write like the Heath Brothers.

This business classic resonated with my long career in high tech. There were no major conclusions that I took issue with. I nodded my head often while reading.

So in a few words — Christenson really knows his material.

The negatives:

At twenty plus years the examples are dated and presented in an academic manner. Disk drives compose the largest of the industry analyses, so some boring examples in many cases.

The charts and graphs are poorly done and it makes one actually appreciate power point slides.

3.5 stars. This read might be most beneficial for someone entering the work force or going through a radical company transformation in high tech or corporate America who has not experienced these dilemmas yet.

The book's primary value lies in its final two chapters. The preceding sections contain bloated corporate garbage and outdated examples that diminish their relevance.

This book was on my list of "Books I should read" for a long time. Maybe this is why it was so disappointing, or maybe I've just read too many modern case studies of business models to find this engaging. It was interesting to read about the origins of many terms that I take for granted (i.e. disruptive technology), but I couldn't really relate any of the examples or theory beyond anything that's already been mentioned by other more recent authors. And its hard for a 20-something to relate to the modernity of disc drives.

Some great stuff at the expense of going through a lot of boring reading. Prosperity Paradox is a much better and wonderful book that highlights some of the same lessons from this book.

This is such a well articulated and well organized book. The book can pretty much be divided into two parts: the problems that arise with disruptive tech and how to deal with them; they are further dissected into eleven chapters for better comprehension of the topic. Sure, you could grasp the crux of the book by reading the summary provided at the end. But the cases provided to complement the author's points turn out to be pretty great and help the readers gain greater insights into disruptive tech.

This innovation classic is still as relevant as ever with well-explained theories grounded in data and practical implications for managing disruptive innovations.

Business cycles move fast. So fast, in fact, that theories about what’s going on rarely outlast them. Such theories “live and die like fruit flies” (The Economist). Every so often, though, an idea with lasting power comes along. An idea that won’t die. The concept of “disruptive innovation” is one of them.

Revolutions can be violent: if you want to create something utterly new, you have to break something. In economics, this is not an entirely new concept. A long time ago, in the 1940s, Austrian-born author Joseph Schumpeter came up with the term “creative destruction.” According to him, destruction can be a good thing, because it helps to advance and restructure the economy.

Half a century later, it was Clayton Christensen who offered a significant update to this idea. It’s hard to overstate the splash his book The Innovator’s Dilemma made when it was published in 1997. Steve Jobs said it had deeply influenced his thinking. Michael Bloomberg sent fifty copies to his friends. Andy Gove, the CEO of Intel, said it was the most important book of the decade. It sold over half a million copies within a year.

Why was the book so successful? Well, it predicted how a significant part of the economy would function in the new millennium – long before apps and e-commerce were omnipresent. And Christensen was right. Today, it feels obvious that innovation has a destructive side: Uber disrupted the conventional taxi system; Amazon disrupted the business of brick-and-mortar stores; and so many other companies are trying to do the same to their industries.

So, let’s zoom in, we’d like to focus on the key concept of The Innovator’s Dilemma: disruptive innovation.

Let’s start with a story.

Who needs cheap radios?

We’re in the United States and it’s the early 1950s. The war is over. People feel hopeful. The economy is booming. More households have more disposable income than ever before, and they’re spending it.

That’s good news for all kinds of industries, from carmakers to the manufacturers of refrigerators. It’s also great for consumer electronics companies like RCA and Zenith. One of their top sellers is the vacuum tube music console – a handsomely veneered cabinet with an integrated radio that sits at the center of middle-class living rooms across the nation.

These consoles are well-made, sturdy objects. More to the point, they’re highly engineered and sound great. All that makes them expensive, but that’s not a problem. This is an age of affluence, and people can afford to pay top dollar for what matters to them – quality. And so that’s what companies focus on. They tinker and improve and continue making big, expensive consoles that sound great.

And that’s when a small Japanese firm called Sony enters the picture. Founded in 1946 with around $6,000 start-up capital, it still has fewer than twenty employees. But Sony’s chairman, Akio Morita, has an idea.

He takes up residence in a cheap hotel in New York City and starts negotiating a license to patented transistor technology owned by the American telecommunications company AT&T. Morita gets his license, but AT&T executives are baffled by his plan to use the technology to build small radios. Why would anyone care about small radios, they ask. His answer is cryptic: “Let’s see.”

Sony’s portable transistor radio appears on the market in ’55. It’s a terrible radio. The static is so loud you can hardly hear the music, and the fidelity is much lower than those vacuum tube consoles. If you’re an affluent household that values sound quality, there’s no chance you’re buying a Sony radio! But what if you don’t have a lot of disposable cash? What if, in other words, you’re a typical American teenager? Well, the alternative to crappy transistor radios for ’50s teenagers is no radio, and so they start buying a lot of Sony radios!

You can probably guess where this story is going. Sony’s crappy radios give the company a crowbar to prize open the American market. And, slowly but surely, transistor technology improves. By the time it’s so good that it becomes interesting to more affluent market segments – those teenagers’ parents, say – it’s already too late for companies like RCA and Zenith to catch up to Sony.

That is how Sony came to dominate the radio market in the United States.

Convenience trumps quality.

Business analysts had a neat explanation of why established companies like RCA and Zenith end up losing out to upstarts like Sony. It goes like this.

Technological change is fast and furious; you have to run to stand still. Managers, though, often lose sight of this fact. They’re so focused on what works in the present that they fail to plan for the future. That’s how they get picked off. Call it complacency. Call it lack of innovation. Call it bad management.

But for Christensen, that isn’t the moral of the Sony story or any of the many other stories that follow the same pattern. When he looked at industries in which incumbents were overtaken by new entrants, he realized that technological breakthroughs were rarely the work of plucky start-ups – they were typically developed in the well-funded R&D departments of big companies. As we saw, Sony, a new entrant to the radio market, piggybacked the sophisticated technology of an established player – AT&T. Then there’s Kodak, the market leader in photographic film for much of the twentieth century before it was devoured by digital entrants. The first digital camera, though, was developed by a Kodak engineer in the late ’70s! There are countless other examples.

So, the real question isn’t why big companies fail to innovate – it’s why they don’t capitalize on the breakthrough technologies they often have a hand in developing. Christensen’s answer is that breakthrough technologies usually are worse than what already exists. Sony’s portable radios sounded terrible. The first cell phone cameras took awful pictures. The first car Toyota released in the American market, the Corona, couldn’t hold a candle to the vehicles rolling off GM and Ford’s production lines.

Christensen sees low-quality innovation of this kind as fundamentally disruptive. He compares it to “sustaining innovation” – the constant tinkering that leads to higher performance. To go back to radios, companies like RCA and Zenith were constantly innovating their core product, which sounded better and better over time. Sony disrupted that pattern. Akio Morita didn’t work in his lab until his transistor radios could compete with the radios made by the industry’s big hitters. Instead, he gambled on finding a new market which would value portability and low cost over quality.

It had to be a new market, too. Established companies’ customers aren’t interested in breakthroughs: they already have something that’s proven to work really well. And from a manager’s perspective, it’s perfectly rational to ignore shoddy new products that have no existing market and focus a company’s resources on improving the high-margin products that do have customers.

Those new markets often end up being hugely profitable, however. Teenagers will buy crappy radios if they’re cheap and portable. Cell phone cameras were so convenient, people used them even though they took grainy photos. Toyota’s Coronas looked like rust buckets, but they got people to work for less money than GM’s or Ford’s cars. All these products were extremely useful.

Which brings us to the dilemma in the book’s title. You can’t invest in every dumb-sounding new idea – that’s how you bankrupt a company. But say you continue pursuing those high margins while waiting to see if that dumb idea turns out to be a stroke of genius. By the time you find out that it is, it’s already too late: the new market that’s suddenly interesting enough to enter has already been cornered. Even worse, the shoddy, low-end products created by upstarts are likely to improve to the point that they become attractive to your customers. That’s also a recipe for bankruptcy.

Why Gillette is stuck on the horns of a dilemma.

Let’s recap. There’s sustaining innovation. And there’s disruptive innovation.

Sustaining innovation improves existing products. We can take Gillette as an example – a company which proudly states on its website that it’ll only stop making razors when it can’t make them any better. First-generation Gillette razors were fairly straightforward pieces of a kit: a two-piece safety razor with a double-edged blade attached to a reusable handle. Today’s battery-powered razors, by contrast, feature five anti-friction blades, lubricating strips, and a precision trimmer for sideburns.

Are new Gillette razors better than the old ones? Sure. Are they also overengineered and overcomplicated? The Dollar Shave Club, a new entrant to the razor market, thought so. Lots of people don’t want to spend small fortunes on complicated razors, the start-up thought. They want something that’s simple and cheap and works. Offer to deliver those razors directly to people’s doors, and you’ve created a new market in which comfort trumps quality. That’s disruptive innovation.

Unfortunately for incumbents like Gillette, new entrants move upstream into high-value markets. That’s what companies offering home delivery of razors are now doing. The American brand Harry’s, for example, now sells its products online and in department stores, Gillette’s old stomping ground.

Gillette, in other words, is stuck on the horns of a dilemma – the “innovator’s dilemma.”

---

Stuck in the innovator’s dilemma: that’s a scary place to be. Is there a way out? In Gillette’s case, it’s too early to tell – we’ll have to wait to see if its own home delivery subscription service will be enough to fend off competitors. But Christensen’s book isn’t really about finding a way out. Its biggest lesson is that managers have to avoid the trap in the first place.

As Paul Steinberg, the chief technology officer for Motorola Solutions, put it, Christensen’s message is that companies must learn to incubate new ideas or perish. Steinberg adds that that message “scared the crap” out of him when he first read The Innovator’s Dilemma. He wasn’t alone. Christensen’s greatest legacy may well be that he taught a generation of business leaders that fear is often the best guide on the path to success.

God, business books can be so dense and boring.

While I do believe Clayton Christensen is right on the money with his hypothesis, framework and careful (OH SO CAREFUL) curation of case studies in disruptive/innovative tech and business, I really wish he and his editor worked together to make this a bit more easily digestible. My favorite break down was towards the end with exemplifying electric cars versus gas cars and drawbacks. Because the metaphor and case studies were more current and recent, the premise was much easier to grab onto than disc space and computer case studies.

A reread.

This book (or close clone) could benefit from an update to contextualize the theoretical applications, which made this an extremely useful read when it first came out.

Good management doesn’t always win. Grappling with and exploiting disruptive technologies in a way that allows an historically profitable company to jump to the next escalator requires courage and creativity that often doesn’t fit neatly into the world of quarterly investor briefings and daily stock movements.

Think about Sears or NCR a generation or so again…….hard to remember these were giants in the past and today just sad memories. Figure out what they should have done and you’ll understand the crux of this book.

A brilliant book on Innovation & Strategy! Prof Christensen aims to why Great Firms always lose out to Disruptive Innovations. The book is divided into two parts: Why Great Firms fail & How Great Firms can defend their empire. The juice lies in the first part!

3 Key Points from the Book on Why Great Firms Fail
1) Disruptive vs Sustaining Innovations.
*Sustaining innovation = improvements to the current performance thru tech advancements.
*Disruptive innovation = Creating a brand new value proposition (possibly with the same tech)
e.g. iPhone with features any smartphone in the market had but re-positioned as simple, elegant, lifestyle device.

2) Big Firms don't want to enter into disruptive technologies because cost is high, low-profit margins, cannibalizes existing products sales (e.g CD makers unlikely to make Thumbdrives).

3) Performance oversupply. Sustaining innovations take place at a rate that it exceeds what consumers want (e.g. Apple vs. Samsung specification war. Extremely powerful processor, pixel-perfect screens, Animojis and a whopping 1+k price tag). Do customers really need them? This opens up the lower end market (new entrants like Xiaomi, Huawei).

I was surprised to find out that the book was first published in 1997. But the principles and ideas discussed are relevant till today. Steve Jobs said he was profoundly influenced by this book! Definitely worth a read!

A very interesting thesis with compelling examples.
