Experiment passport
- Growth model
- Break revenue down into actionable variables: volume, conversion by step, value, retention. We test where the lever actually exists.
- Instrumentation
- Without reliable measurement at each step, a test proves nothing. Reading precedes experimentation.
- Backlog
- Hypotheses stated explicitly: what changes, for whom, and the expected effect on which variable.
- Prioritisation
- Estimated impact, confidence in the hypothesis, implementation effort. Costly, low-confidence tests wait.
- Protocol
- One variable at a time, defined population, duration fixed before launch, written stopping rule.
- Reading
- An honest outcome: conclusive, inconclusive, or unreadable for lack of volume. All three are useful.
- Industrialisation
- What works becomes a documented standard, built into processes and permanent pages.
