Write the decision before launching the test
Start with a claim you could change: a specific role owns the problem, a trigger predicts relevance or a standard evaluation can resolve adoption risk. Define what evidence would support, weaken or leave that claim unresolved. Do not convert a preferred outcome into a 'success' rule after seeing the data.
Keep account conditions and execution sufficiently consistent to make comparison useful. Record delivery issues, contact coverage and seller changes so they are not mistaken for buyer rejection. A small operational test is often valuable for deciding the next step, but it is not automatically a statistically significant market study.
| Decision | Evidence to use | What changes next |
|---|---|---|
| Hypothesis | Specific operating condition, buyer role or offer assumption | State what would change your mind |
| Execution | Comparable cohort, message or discovery approach and owner | Avoid uncontrolled changes where practical |
| Decision | Evidence window, limitations and continue/change/stop rule | Use results to choose the next action |
Work through the decision
Illustrative experiment: test whether engineering or product leadership is the better first contact for entitlement changes at a narrow account cohort. Keep account criteria and opening question consistent, and log referrals as well as replies.
A referral from engineering to product is useful evidence even without an immediate meeting. A mailbox failure is not evidence against the buyer-role hypothesis. At review, separate these outcomes and decide whether to refine coverage, change the question or investigate the account condition. Do not claim a market-wide conversion rate from a small convenience sample.
Success is defined after the results arrive
Changing the metric to whichever number improved makes the experiment hard to learn from. Keep the original question and decision rule in the record. Unexpected findings can guide a new test without rewriting the first one as a success.
A concrete next step
Write a one-page experiment brief with hypothesis, cohort, action, owner, evidence and decision rule. Ask someone uninvolved to explain what result would make the team stop.
