Test Cards

The purpose of the test card is to clearly define what you will test in an experiment. The more you can define it the easier it will be to validate or not the experiment. What is a good experiment? A good experiment is precise enough so that team members can replicate it and generate usable and comparable data.

  1. Make sure you have created assumptions and done an assumption mapping exercise
  2. Pick the most critical assumptions from the top right quadrant of your Assumptions Map.
  3. Print Test Card templates or use a similar digital solution


  1. Start by describing the background and context
  2. Follow the steps on the Test Card and add information
    1. Hypothesis
    2. Test
    3. Metric
    4. Criteria
  3. Check how critical, cost, reliability, and time required if possible
  4. Create as many Test Card you think is possible to test in the next test phase.
  5. Your next step is to design your actual test or experiment.
