[2007] A provocative title and premise. Probably some good ideas in here. But I found the case studies so dry and boring, yuck! Read this primarily because Christensen is considered an important thought leader by my company. ( )

I must admit I breezed through this one. Not because the information is bad but because the information is now a standardized focus in any good business book (of which I have read not a few). But, gathering from his premise, this information was not as widely known when he published the book, therefore I didn't think it was worth docking stars.

Interestingly, his information regarding older firms going under because of new firms' unseen strengths has played out. Particularly telling was his comparison on Kmart beating out Sears(yes, even 20 years ago Sears was struggling). Looking now at the defunct-ing Kmart/Shopko superstores, they have (as he predicted) forgotten what got them there in the first place and are now being lambasted by stores like Target and Walmart who jumped on the Amazon(aka innovative tech) bandwagon.

Final point that I thought was brilliant: you can't predict what will be the new thing because the customer doesn't know what it is/wants until that new thing actually exists. Take that HiTech and Sandra Foster (#[b:Bellwether|24985|Bellwether|Connie Willis|https://images.gr-assets.com/books/1431535122s/24985.jpg|1194887]). ( )

This is pretty much part of the canon of startup books, and explains why startups, or teams structured like startups, routinely out-compete large organizations in certain kinds of new technology (while being defeated in other kinds of new technology). Christensen basically splits technological shifts into sustaining vs. disruptive innovations, largely around whether developing and implementing them will require shifts in the "value network" of a company (the customers, distributors, suppliers, etc.). He makes a data-supported case that in disruptive innovation, the very things which make organizations efficient and successful at scale work against success in innovation.

The most famous examples he uses are getting a bit dated (the shift in computer storage from disk packs down to 14, 8, 5.25, 3.5, 2.5, 1.8, and 1.3" hard drives -- i.e. the storage hardware devices used in ancient history before flash/ssd on phones and whatever-magic-space-technology is used in the cloud; various types of motorcycles, i.e. some dead dinosaur juice fueled devices used before Uber or Lime...), but everything is just as applicable today. ( )

Some books are important when they are new and not so important twenty years later. This is one of those. With this book Clayton Christensen made the term "disruptive technology" mainstream and created a new language when discussing technological and market evolution. Now we are used to that term. iPhone was disruptive, Internet was disruptive, the web was disruptive, anything that makes parts of the market obsolete is disruptive.

But now, 20 years later, the book has been so successful that it is not really needed. It talks about things that most people that care have already learned.

Basically: Smaller organizations are better at handling small opportunities that may later be large business. Larger companies can't both handle the large business and the small opportunities.

I think he's right but it's no help when trying to find those small opportunities that will later become large businesses and that is the hard problem. If you solve that part, then sure, this book says it's best to handle it in a completely (very completely) separate organization from the "business as usual" or one or both branches will suffer badly.

The most interesting part is the historical comparisons, mostly from the retail industry and the disk drive industry. Disk drives went from 14 inch packs to 8 inch floppy disks to 5.25 inch floppy disks to 3.5 inch not so floppy disk. This is basically where the book ends though he mentions 1.8 inch disks as well. (We now know that there was no next step evolutionary step, zip disks don't count. The next step was instead a combination of CD-ROM/RW and flash disks, and network connected storage.)

One good thing with the edition I consumed is that it was short. Could maybe have been even shorter, but it's rare that (American) authors present their ideas compactly. Too hard to sell short books I think which is a bit crazy. I see that some other reviews complain that it's too repetitive so I realize my edition was a shortened version. ( )

A great book that explains why better products are often not able to beat new and somehow inferior products and why big companies cling on their old products until they have almost lost.
