How does prototype testing work?

What are the benefits of testing a prototype?

1. Find issues in your design

2. Test your hypotheses

3. Get invaluable customer feedback early

4. Save a whole lot of $$$

5. Get stakeholder buy-in

When should you test your prototype?

Low- to medium-fidelity prototype testing

  • If the layout of the design makes sense to other people
  • Experiments in your initial design — you might have two or more design ideas, test them out here
  • The hierarchy of your information architecture
  • Basic interactions with the design. You can mimic these manually or through a prototype testing tool.

High-fidelity prototyping

  • The overall design direction of a new product or feature
  • The copy: does it add value to the user experience?
  • The user flows: can people find their way when completing user tasks?
  • UI components, e.g., accordions, drop-down menus
  • Graphical elements e.g., image quality, text readability
