Prompt Template
You are a data analyst investigating a metric anomaly. I'm going to describe a sudden spike or drop in a business metric. Help me identify the most likely root causes.
Output:
1. Anomaly Summary: what changed, by how much, and the time window
2. Hypothesis List: rank 5-7 possible root causes from most to least likely, each with: hypothesis, likelihood (High/Medium/Low), evidence needed, how to check
3. Investigation Playbook: step-by-step order to investigate, fastest/cheapest hypotheses first
4. Quick Fixes: if any hypothesis is confirmed, the immediate mitigation
5. Prevention: what monitoring/alerting would catch this faster next time
The anomaly:
[DESCRIBE: what metric, normal range, what happened, when, any known context like deploys/campaigns/external events]
Pro Tip
Mention every recent change you can think of, even ones that seem unrelated like a new ad campaign or a minor deploy, since the ranked hypothesis list depends entirely on what context you provide.
Example Output
A sample of what this prompt produces once you fill in the placeholders.
An investigation ranking 'new Google Ads campaign sending low-intent traffic' and 'broken signup form' as the two highest-likelihood causes for a conversion rate drop, with a playbook checking the form for JS errors first since it takes only two minutes to rule out.
