What is a prototype? A prototype is a design tool used to help create a new product, much like a model. There are different kinds of prototypes; some are more like rough drafts and some are more like the final version. When you first come up with an idea for a new product, you'll probably sketch it out so you can show people what you're thinking of: This is one version of a prototype. But as time goes on, you'll want to make your drawing more detailed, especially if you're thinking about creating a complicated system.
