Minimum Viable Product

I'm challenged (in the best way) and intrigued by this idea of creating the "minimum viable product." It all goes together with the idea of "rapid prototyping" - which is easier and easier in this digital world.Here's a clip from Eric Ries on the topic. I'm looking forward to reading his book, The Lean Startup.http://ecorner-beta.stanford.edu/swf/player-ec.swf
