• Documentation debt tracking

2. Requirement Tracking

• Total requirements by category
• Requirement status (draft, approved, implemented, tested)
• Requirement coverage (REQ → BDD → TASK mapping)
• Orphaned requirements
• Requirement age and staleness

3. Traceability Analysis

• Complete traceability chains (BRD →... → Code)
• Broken traceability links
• Traceability coverage percentage
• Gap identification
• Circular dependency detection

4. Implementation Progress

• Tasks completed vs total
• Implementation phase progress
• Blocked vs active tasks
• Timeline adherence
• Milestone tracking

5. Velocity Tracking

• Requirements completed per sprint/week
• Implementation velocity
• Documentation velocity
• Test coverage velocity
• Trend analysis over time

6. Quality Metrics

• Code review scores over time
• Test coverage trends
• Security vulnerability trends
• Code complexity trends
• Documentation quality scores

7. Bottleneck Identification

• Stuck requirements (no progress)
• Blocked tasks
• Resource constraints
• Dependency chains blocking progress
• Review bottlenecks

8. Custom Report Generation

2. Backward Traceability 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

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

• Reports saved to reports/analytics/
• Historical data stored in metrics/history.json
• Dashboard auto-refreshes every 15 minutes
