### Traceability KPIs

1. **Forward Traceability**
   ```
   Forward = (Requirements with downstream links / Total Requirements) × 100%
   Target: 100%

   ```
   Backward = (Tasks with upstream links / Total Tasks) × 100%
   Target: 100%
   ```

3. **Complete Traceability Chains**
   ```
   Complete = (Requirements with full BRD→Code chain / Total) × 100%
   Target: ≥95%
   ```

### Quality KPIs

1. **Code Coverage Trend**
   ```
   Track: Weekly, target: ≥90%
   Alert: If drops >5% week-over-week
   ```

   ```
   Track: Per PR, target: ≥80/100
   Alert: If average <70 for 2 consecutive weeks
   ```

3. **Security Vulnerability Density**
   ```
   Density = Critical vulnerabilities / KLOC
   Target: 0 critical vulnerabilities

## Best Practices

1. **Update frequency**: Daily automated collection, weekly reports
2. **Baseline establishment**: Set baseline metrics at project start
3. **Trend analysis**: Focus on trends, not absolute numbers
4. **Actionable insights**: Every metric should inform decisions
5. **Anomaly detection**: Alert on unusual patterns
6. **Historical data**: Maintain 6+ months of history
7. **Stakeholder alignment**: Customize reports per audience
8. **Continuous improvement**: Evolve metrics based on feedback

---

## Limitations

1. Requires consistent SDD artifact structure
2. Historical analysis limited to available data
3. Predictive accuracy depends on data quality
4. Cannot measure subjective quality factors
5. Requires regular data collection for accuracy

---

## Success Criteria

- Real-time dashboard availability
- <5 minute report generation time
- 100% data accuracy
- All KPIs tracked automatically
- Trend analysis with 90% forecast accuracy
- Zero manual data collection required
- Stakeholder satisfaction ≥4/5

---

## Notes
