What is a Prototype?
One of the most important steps in the design process is prototypes. They are referred to as the sample version of a final product that is used prior to launch for testing.
The role of a Prototype
By placing an early version of the solution in front of actual users and gathering feedback as quickly as possible, prototypes allow designers to validate their ideas, and make improvements.
Key point:Prototypes are the last step in the design process, after wireframes and mockups.
