The Lean Startup

The Lean Startup: How Today’s Entrepreneurs Use Continuous Innovation to Create Radically Successful Businesses by Eric Ries introduced a methodology that has transformed how startups and established companies approach product development and innovation. Drawing on lean manufacturing principles, Ries introduces the concept of the Minimum Viable Product (MVP), the build measure learn feedback loop, and validated learning the practice of treating every product decision as a hypothesis to be tested with real data from real customers as quickly and cheaply as possible. The book challenges the traditional startup model of long planning cycles and big launches, replacing it with rapid experimentation, customer feedback, and the willingness to pivot when evidence demands it.
