This concept is at the heart of "The Lean Startup." Ries emphasizes the importance of learning what customers really want through direct experimentation and feedback. Instead of relying on assumptions, startups should build minimum viable products (MVPs) to test their hypotheses and gather data. This approach helps in making informed decisions and reduces the risk of failure.

This cycle is a core principle of the lean startup methodology. It involves building a prototype or MVP, measuring its performance through customer feedback and data analysis, and learning from the results to make necessary adjustments. This iterative process allows startups to refine their products continuously and align them more closely with market demands.

One of the most critical decisions a startup must make is whether to pivot or persevere. A pivot involves making a fundamental change to the product or business model based on validated learning. If the current strategy isn't working, a pivot can help redirect efforts towards a more promising direction. On the other hand, if the data shows positive results, the startup should persevere and continue refining its approach. This flexibility is crucial for navigating the uncertainties of the startup world. <h2>Key Ideas</h2>
