One‑Page Experiment Brief

This one‑page experiment brief helps teams make experiment intent visible, concise, and consistent. Use it to attach a short, scannable plan to work items, tickets, or stakeholder updates. Fill only what’s needed; keep the brief lean. Guidance and examples are provided below each field.

Why this matters

Short, structured briefs speed approvals, reduce ambiguity, preserve learning, and make it easier to compare and reuse experiments later. Prefer clarity over completeness: capture the hypothesis, the primary metric and guardrails, who owns it, how you will measure it, and what success looks like.

Quick example

Hypothesis: If we show a shorter signup form, then conversion from visit to signup will increase by 8% because fewer fields reduce friction.
Primary metric: Signup conversion rate (baseline 5%, target 13%).
Success: >=8% relative lift without >2% increase in support contacts.

Short, descriptive name that fits in a single line (e.g., 'Short Signup Form A/B').
Describe the intervention or change you will make. Keep to one sentence.
State the expected measurable outcome (what you expect to see).
Brief rationale or prior evidence supporting the hypothesis.
Name the single primary metric you will use to judge this experiment (e.g., conversion rate, mean time to resolve).
Current value or short description of how the metric is measured.
Numeric or relative target for success (e.g., +8% relative lift or target = 13%).
Important metrics or thresholds you will monitor to ensure the change doesn’t cause harm (e.g., support contacts, error rates).
Planned sample size or number of users/events. Leave blank if not applicable to your experiment design.
Who or what will be included and the planned timing (e.g., 2 weeks, 10k impressions). Include time zone when relevant.
Name of the person accountable for running the experiment.
Role or team (e.g., Product Manager, Ops Lead).
Best way to reach the owner for quick questions.
URL to dashboards, tracking plan, ticket, or analytics query that will be used to measure the metric.
Reference to the work item where this brief will be attached (optional).
Precisely state what will count as success (use the primary metric and guardrails).
What outcome will cause you to stop or pivot the experiment?
Immediate actions to take after the experiment completes (both for success and failure).
Who should be informed of results and decisions (teams, roles, or individuals).
Quick subjective confidence check (low to high). Use to communicate uncertainty with stakeholders.

Any other context, constraints, or assumptions worth preserving for future learning.
