Even good ideas need to be tested.


Test your prototype and gain feedback on your solution.


It’s important to validate or invalidate your hypotheses about what motivates behavior and gain feedback to improve your solution.

When to move to the next step:

You have tested your prototype and incorporated feedback from your target audience. Note: You might have to return to Prototype and Test more than once!

Diversity, equity, and inclusion considerations:

  • Ask who is represented in your test group
  • Consider any potential negative impacts/harm for those who participate
  • Consult local experts
  • Compensate people for their participation if appropriate
  • Commit to incorporating feedback on the solution
