I suppose I wasn't very clear, but what I was trying to say is that a lot of entrepreneurs are turning to Lean for a framework that will lead them to success. That's about as big of a misunderstanding as thinking being able to predict the weather will allow you to force a sunny day tomorrow. Eric Ries has never claimed to be able to do the latter, and I was just pointing that out. But right up there with misunderstanding #1 about Lean (i.e., "Lean means bootstrapped cheap right?") has got to be this particular misunderstanding.

What I meant by jury is still out, is that we might find that the framework suggested in The Lean Startup actually increases success rates amongst startups in addition to being a model for revealing truth. Revealing truth faster will allow startups to extend their runway and if we find that most successful businesses only require X pivots on average before they start to profitable, we very well might see startups be able to accomplish these X pivots succeed where they may have followed a more traditional launch and pray model and achieved fewer than X pivots, running out of runway.

If it sounds like I'm trying to be negative about the book, I'm not. It's fantastic and I'm absolutely suggesting everybody buy a copy :P
