Build-Measure-Learn cycle: core principle of the Lean Startup

The build-measure-learn cycle is an iterative process that is at the centre of the lean startup methodology and aims to accelerate product development through rapid learning from real user experiences. Through the cycle, companies build a minimal product, measure how customers react to it and learn from this to continuously improve the product or service in rapid iterations. This method enables startups to work more efficiently by focusing time and resources to develop exactly what the market needs, minimising the risk of bad investments.
