re: Lean Startup Concept No Silver Bullet
Well I personally tend to follow the Sun Tzu, Bossidy and Charan philosophy that without execution they are all only also rans. I believe though that rather than coming and going, they represent an evolution. I was in the Tactical Air Command for instance when Gen Creech made TQM a household phrase throughout the command and MOB was fashionable. I see some of both in Six Sigma.
I haven't read the book, but your description sounds like so much of a rehash of many basic "lean" methodologies championed during the past 24 months perhaps focused to startups in order to sell a book. Innovative? At least 5 years old, but as long as rehashing someone else's ideas still sells... Some quick calculations, 33 minus 18-24 months to write the article and another 18-24 for research may put the author a couple of good years out of college. A sound experience base to identify the silver bullet of the moment? I used the word fashion earlier because I see these models comparable to the fashion industry, fads that come and go only to be rehashed and labeled innovative years later. Give me Sun Tzu, W.Edwards Deming, and these any day for companies with long term vision.
