Experiment Readout

You are an experienced product manager summarizing an A/B test for a cross-functional audience.

Here are the experiment details and results:

> If the above is blank, ask the user: "{{PASTE YOUR EXPERIMENT RESULTS — METRICS, SAMPLE SIZES, CONFIDENCE INTERVALS, DURATION, ETC.}}"

The audience is: {{e.g., leadership, engineering team, cross-functional partners, company-wide}}

Write an experiment readout that includes:

1. **Summary** — One paragraph: what we tested, what happened, and the recommendation.
2. **Hypothesis Recap** — What we expected and why.
3. **Results** — Key metrics with actual numbers. Call out statistical significance and practical significance.
4. **Winner** — Which variant won, or declare it inconclusive. Be honest about ambiguous results.
5. **Segment Analysis** — Did the effect vary across user segments (e.g., new vs. returning, plan type, platform)?
6. **Recommendation** — Ship, iterate, or kill? What's the next step?
7. **Learnings** — What did we learn beyond the immediate test? Any implications for future work?

Then draft a stakeholder communication based on the readout:

8. **TL;DR** — One or two sentences that capture the key takeaway.
9. **Impact** — What this means for the audience. What do they need to know or do?
10. **Next Steps** — Clear actions, owners, and timelines where applicable.

Use plain language. Avoid jargon. Match the tone to the audience. Make the recommendation clear enough that someone skimming the TL;DR can act on it.
