Description
The test card is a tool to keep track of hypotheses you have, design experiments to test those hypotheses and run the tests. This will help you to base decisions not just on believes and assumptions but on actual data.

How to use the template
1. Fill out the test card by (1) stating your hypothesis, (2) explaining the experiment you want to conduct to test the hypothesis, (3) defining clear metrics of what will be measured in the experiment and (4) what the exact outcome needs to be to prove or disprove the hypothesis.
‍
2. Do this exercise for all the hypotheses you have and consider having several experiments and test cards for the same hypothesis, to increase reliability of the tests.
‍
3. Prioritize your test cards and start with the experiments that are easy to implement and costs little (don't invest a lot early because easy tests might already lead you into new directions)
‍
4. Conduct experiments and use learning cards for each experiment
