When you are developing a service or a product as a start-up, you need a continuous flow of feedback from customer side to realize what they want and keep your process in a right direction. “Build, measure, learn” feedback loop is a methodology that helps you to do so.

Your first task is to define the idea that you want to test and the information that you need to learn. You do this by developing a hypothesis – your prediction of what will happen during the experiment .

Also, let’s see what Eric Ries, the father of the Lean Startup concept, says about Build-Measure-Learn feedback loop.

The model may be called “Build-Measure-Learn” but, if you follow that sequence and jump in at the “Build” phase, you’ll be missing the mark. Instead, it’s essential to start with a planning stage.
