A UX prototype is a simple version of your final product, which you use to test the design before launch. The earlier you test a prototype, the more user-centred the development and the less likely you’ll waste time and money launching a failure.

You may hear the term fidelity when it comes to prototyping…

• High fidelity prototype: the model is as close to the finished, fully workable and realised product as possible.
• Low fidelity prototype: the model is incomplete, simple and has the very broadest idea of what the finished product will look or feel like.
