1. Use a one-page summary format
Stakeholders want clarity, not a full deck. Keep summaries to one page or one screen with these sections: decision, impact, confidence, and next steps.
If a summary requires scrolling more than once, it is too long.
2. Translate metrics into impact
Instead of "conversion up 2.1%," state the impact: "This adds ~120 more weekly signups." Tie the metric to a business outcome so the decision feels concrete.
Include the baseline so the lift makes sense.
3. Call out confidence and caveats
Stakeholders need to know what you are confident about and what is still uncertain. Use a simple confidence label (high, medium, low) and list any caveats such as seasonality or low sample size.
4. Recommend a clear next step
A summary should answer "what happens next." If the decision is to ship, state the rollout plan. If the decision is to iterate, outline the next test. If the decision is to stop, explain what will replace the idea.
5. Archive summaries in one place
Keep a shared folder or wiki with every summary. This creates a searchable history and helps new stakeholders understand why the product evolved the way it did.
Make the format consistent
Consistency builds trust. When stakeholders know what to expect, they spend less time interpreting the summary and more time making decisions.
