Prototype testing plan

How can it help me?

This worksheet helps you plan a prototype - a way of modelling and testing your idea. This can uncover the holes in your project, showing you what needs to improve, as well as sparking new ideas.

How do I use it?

  • Set out a key element you would like to test in the ‘Hypothesis’ box.
  • Follow the instructions in the next two boxes to test your idea using different methods.


  • Use what you have at hand to make your prototype. It’s meant to be a quick visualisation of your idea to highlight any potential issues, rather than a product in itself.
  • You should prototype often, at the different phases of your idea’s development.
