Product Metrics Dashboard Design

Design a metrics dashboard for tracking {{product_area}} performance.

Business context: {{business_context}}
Key stakeholders: {{stakeholders}}

Define metrics across these categories:

1. **North Star Metric**
   - What single metric best captures value delivered?
   - How is it calculated?
   - Target and current baseline

2. **Input Metrics** (leading indicators)
   - Metrics we can directly influence
   - How they connect to the North Star

3. **Output Metrics** (lagging indicators)
   - Business outcomes we expect to see
   - Timeframe for impact

4. **Health Metrics** (guardrails)
   - What should NOT get worse
   - Acceptable thresholds

For each metric provide:
- Definition and calculation
- Data source
- Refresh frequency
- Owner
- Target vs baseline
