Introduction:
A prototype is a conceptual model, a preliminary depiction of the ultimate intent or idea of a design. Prototypes tend to be incomplete models. They provide the basis for working out design ideas, testing assumptions, and obtaining feedback from users.

Prototype Advantages:
Improve communication
Decrease development time
Reduce project cost and minimize risk
Minimize the number of design-process modifications
Extend product lifetime by adding necessary features and eliminating redundant ones early in the design process
Enable design variations
Enable greater product complexity, if desired
Decrease delivery time, ultimately facilitating quicker introduction to the marketplace
