The A/B test crap is just that.. crap.
Where Lean does make sense is applying the scientific method to the startup process. If you can identify your assumptions, figure out a way to test them, and then adjust accordingly, that is a fantastic thing. Every assumption is a risk, this is just a process for addressing/mitigating them to determine which are "good enough."
That said, every time I hear the word "pivot," I want to hit someone. It's been so misused and abused that it's lost most of the meaning. :(
Point of Lean is to think in a structured and rigorous way about problems. Not just to look at A/b results but to always be aware of the hypothesis that underlies any decision.
How about you? What are you reading/doing?
the answers to which are probably: - no, not just yet, but we hope it's useful - definitely - maybe, and we'd love your help figuring it out :)
in other words, it's a work in progress with some very likely positive benefits, but by no means a perfect science (yet, anyway).
