A practical starting point
A growth experiment tests one assumption with a bounded amount of work. It should tell you something useful even when the result is disappointing.
State the hypothesis, audience, channel, measure and time window before starting. Compare like-for-like results. Avoid changing the message, audience and offer at the same time.
Record what happened and what you would do differently. Small samples are uncertain, so look for repeated evidence before making a major commitment. Growth follows learning and delivery capacity together.
The practical guide below works through a hypothetical example, the decisions to check and a way to review the result. Use it to prepare questions for your own situation; adapt the exercise to the information and tools you are authorised to use.
Lean Growth Experiments should end with a practical next step: keep the change, revert it or gather more evidence. Write the reason and the uncertainty. Productised Services gives you a clearer offer to test, while Founder Systems helps the team handle the enquiries that follow. Do not scale an experiment just because its headline number looks positive; check whether the resulting work fits your capacity.
