What is Functional Prototype?
A design prototype that functions almost like the final product. Such a prototype is used in usability tests, especially where navigation is important.
A functional prototype acts as a visual unit that can be simulated, enhanced, and learned. A functional prototype brings your mental formalization of a product into its actual form, feel, and function. It is a decisive step toward designing an idea, invention, or new product.
It is a sample or model of a product created to test a concept or process or to serve as a visual prop to replicate, improve, and learn from it. This term is used in a variety of contexts, including semantics, design, electronics, and software programming, but is most common in product development.
