A lo-fi prototype is a simple, often rough-around-the-edges version of a product or idea that is used to validate the concept. It is a way to test out the idea in a practical way and get feedback from real users. By creating a low fidelity prototype, teams can quickly assess the feasibility of their concept and identify potential areas for improvement, allowing them to refine the design before investing more time and resources into a higher-fidelity version.
