Prototype development is the process of creating an early model or sample of a product to test and validate ideas. This initial version, known as a prototype, allows designers and engineers to explore concepts, identify potential issues, and gather feedback from users. Prototypes can vary in fidelity, from simple sketches to fully functional models, depending on the stage of development. The main goal of prototype development is to refine a product before full-scale production. By using prototyping techniques, teams can iterate on designs, improve usability, and ensure that the final product meets user needs and expectations. This approach helps save time and resources in the long run.
