Prototype development is the process of creating an early model or sample of a product to test its design and functionality. This initial version, known as a prototype, allows designers and engineers to explore ideas, identify potential issues, and gather feedback from users. Prototypes can vary in complexity, from simple sketches to fully functional models. The goal of prototype development is to refine a product before mass production. By using prototyping techniques, teams can make informed decisions, reduce costs, and improve the overall quality of the final product. This iterative process is essential in fields like software development and product design.
