About evaluating startup success:
The two most important assumptions are the value hypothesis and the growth hypothesis. These give rise to tuning variables that control a startup’s engine of growth. Each iteration of a startup is an attempt to rev this engine to see if it will turn. Once it is running, the process repeats, shifting into higher and higher gears.[]”
Eric Ries – The Lean Startup
“Startups have a similar engine that I call the engine of growth. The markets and customers for startups are diverse: a toy company, a consulting firm, and a manufacturing plant may not seem like they have much in common, but, as we’ll see, they operate with the same engine of growth.
Eric Ries – The Lean Startup
Every new version of a product, every new feature, and every new marketing program is an attempt to improve this engine of growth.”
