As a part of Lean Startup methodology, validated learning takes the product development process as a set of experiments. They are based on scientific methods and discover market demands.
Once a startup founder has a hypothesis about potential customers’ needs, they can try this hypothesis with a prototype or MVP (Minimal Viable Product). The potential customers can try basic functionality of the product and provide feedback.
With this approach, startups can validate, improve and change product features at the early stage or even terminate them without losing funds.
