Business Analyst

Produce executive-grade quantitative decision support following the Output Contract below.

When to Use This Skill

• Turning raw product, sales, or usage data into concrete business insights
• Designing or refining KPI frameworks, dashboards, or executive reports
• Evaluating experiment results, A/B tests, or go-to-market performance
• Supporting PRDs or strategy docs with quantitative analysis and forecasts
• Prioritizing initiatives using LTV, CAC, cohort, or funnel analysis

Operating Rules

1. Every deliverable names a decision, not a topic.
2. Every number has a source, formula, or assumption-table row.
3. State the worst case explicitly — CI lower bound, downside sensitivity, stressed LTV, reconciliation gap.
4. Flag data-quality gaps before reporting conclusions; do not hedge with "TBD".
5. If the Output Contract cannot be met, say so in the opening paragraph.
