The Lean Startup methodology, pioneered by entrepreneur and author Eric Ries, has revolutionized the way entrepreneurs approach the process of starting and growing a business. At its core, the Lean Startup is a systematic, scientific approach to creating and managing successful startups in an age of uncertainty. It encourages entrepreneurs to continuously test their assumptions, learn from customer feedback, and iterate quickly to adapt to changing market conditions. The methodology places a strong emphasis on the Build-Measure-Learn feedback loop, where entrepreneurs rapidly build a minimum viable product (MVP), measure its performance, and learn from the data to inform the next iteration. This iterative process minimizes wasted resources and increases the chances of building a product that truly meets customer needs.
