A prototype is an early model or sample of a product that is created to test and validate ideas before full-scale production. It allows designers and engineers to explore concepts, identify potential issues, and gather feedback from users. Prototypes can vary in complexity, from simple sketches to fully functional versions of the final product. In various fields, such as software development and industrial design, prototypes play a crucial role in the development process. They help teams visualize their ideas, make necessary adjustments, and ensure that the final product meets user needs and expectations.
