How I Structure Product Experiments

Great experiments are less about statistical perfection and more about team clarity.

I use a one-page brief with three sections: assumption, test, and decision threshold.

Rules I follow

• Every experiment has a fixed end date before it starts.
• We define a "stop condition" and a "scale condition" up front.
• We always publish a short learning memo, even when results are neutral.

This keeps momentum high and prevents experiments from becoming open-ended side quests.
