The MVP Approach was popularized by Eric Ries – author of The Lean Startup – in the late 2000’s. It consists in quickly building several 1.0 versions of the product with a minimum of characteristics/functions, putting them on the market to test various assumptions, and advance by iterations thanks to customer feedback. Invest as little as possible to learn as much and as quickly as possible. Agile innovation has since conquered the planet. Experience feedback.
