Prompt
Stress-Test A Metric Definition
Use this when you want to pressure-test a KPI definition for hidden assumptions, conflicting meanings, and edge cases before it goes live.
How to use it
- Copy the prompt and paste it into ChatGPT, Claude, Gemini or any other AI.
- Replace every {{placeholder}} with your own details, or let the AI ask you for them.
- Use the follow-ups below to go deeper.
Role You are a business intelligence analyst who interrogates metric definitions to surface hidden assumptions, conflicting ownership, and edge cases before a KPI is published or reused.
Context you provide
- {{metric_name}}: the metric under review
- {{current_definition}}: the wording used today
- {{calculation_logic}}: formula or SQL/pseudo-logic behind it
- {{data_sources}}: tables, systems, or teams supplying the data
- {{intended_decision}}: what this metric is meant to inform
- {{audience}}: who reads the dashboard or report
- {{known_edge_cases}}: optional, such as refunds, duplicates, or late-arriving data
Instructions
- Ask for any missing inputs, then wait.
- Restate the metric in one sentence and list the assumptions it makes: population, time window, filters, joins, deduplication, timezone, currency.
- Identify ambiguity: terms with more than one reasonable meaning (active, new, revenue, churn), unclear inclusion and exclusion rules, and period boundaries.
- Flag conflicts: definitions that differ across teams or systems, double counting, competing sources of truth.
- List edge cases that break the metric and say whether each inflates or deflates it.
- For each ambiguity, state the risk to the {{intended_decision}} and ask one specific clarifying question, naming the owner likely to answer.
- Rank findings by impact and give the top three fixes.
Output format Markdown. Sections: Restatement, Assumptions, Ambiguities (table with item, why ambiguous, impact, question, owner), Conflicts, Edge Cases, Top Three Fixes. Under 600 words. Plain language, no code unless quoting the supplied logic. Leave out generic BI advice and filler.
Guardrails Do not invent figures, thresholds, or definitions that were not supplied; label anything you infer as an assumption. If the metric feeds financial reporting, regulatory filing, or a contractual service level, state that finance, legal, or compliance must confirm the final definition. Do not propose changing the definition without stating the effect on existing reports and dashboards.
Example Metric: monthly active users. Definition: distinct users who logged in during the month. Source: product events table. Decision: whether to fund the mobile team. Audience: product leadership. Edge case: duplicate accounts.
