How is the lean machine startup able to save entrepreneurs from shattered dreams, squandered capital and wasted efforts?
Sorry Sammy, it's called lean startup and the name was born out of the Toyota lean manufacturing processes. Please google "Steve Blank Lean Startup Overview" for a good introduction. My best answer to your question is by keeping the entrepreneur in sync with the customer and delivering what they have proven they want to buy. Or, as Paul Graham puts it, make something people want.
