A simple to use template that encapsulates the experiment to run against a defined hypothesis.
The template offers a single view of what is being tested, how it will be measured, success criteria, results from the experiment and the actionable learnings deduced from the results
👥Who
The test and learn card is typically drafted by a product manager or service designer. If the experiment is technically focused, an architect may draft the card
Once drafted it is reviewed and baselined by the whole core team, and may be shared with key stakeholders
🛠 Running the technique
Complete the left hand side of the card - write the target outcome you are hoping for in the format of a prediction. Start the statement with ‘We believe that by (action taken) … (resulting outcome seen) ‘. This is the Hypothesis statement
Define the tests that will be run for the experiment to prove or disprove the hypothesis. Focus on identifying a causal relationship between action taken and resulting outcome to build a high level of confidence in the efficacy of the experiment.
Make sure your hypothesis can be tested empirically, capturing the variables that need to be measured - this ensures that the team can meet the requirements as part of developing and running the experiment
Define the success criteria, what the outcome should demonstrate to deem the hypothesis proven. The success criteria should be definitive, with suitable degrees of confidence(>95%) where large volumes of data may be involved.
Capture a summary of the experiment result, and the key actionable learnings to take forward to prioritise future work in Validation
