Good introduction to a nice Theory,
This review is from: The Innovator's Dilemma: When New Technologies Cause Great Firms to Fail (Hardcover)
Not quite as easy to read as I would have liked. Christensen describes some very interesting & plausible theories, but is somewhat confined into employing the computer disk industry as the rapidly changing example which both demonstrates & proves his theories, and its not necessarily the most exciting case material. Other products only get a minor look-in.
What I did like is how he covers the footnotes at the end of each Chapter - so if they don't interest you, you can skip over them, but if they do interest you, then you don't have to struggle to the back of the book. I wish more authors & publishers would use that technique.
One quibble - given his Economics background - of course there are plenty of graphs, and 99% of them are straight lines - there are no time dependent variances in his world.
Read this before you read the Innovators Solution.
