Building a QA Metrics Dashboard
Metrics without context are just numbers. A good QA dashboard tells a story about quality trends and helps stakeholders make informed decisions.
Essential QA Metrics
Process Metrics
| Metric | Formula | Target |
|---|---|---|
| DRE | Pre-release defects / Total defects x 100 | >95% |
| Test Coverage | Requirements with tests / Total requirements x 100 | >90% |
| Automation Rate | Automated tests / Total tests x 100 | >60% |
| Test Pass Rate | Passed tests / Executed tests x 100 | >95% |
Quality Metrics
| Metric | What It Measures |
|---|---|
| Defect Density | Defects per KLOC or feature |
| Escaped Defects | Bugs found in production per release |
| Mean Time to Detect | Average time from bug introduction to discovery |
| Mean Time to Fix | Average time from bug report to fix |
Delivery Metrics
| Metric | What It Measures |
|---|---|
| Cycle Time | Time from story start to production |
| Release Frequency | How often you deploy |
| Rollback Rate | Percentage of deployments rolled back |
| Lead Time for Tests | Time to create tests for new features |
Dashboard Design Principles
- Audience-appropriate: Technical dashboards for the team, executive summaries for leadership
- Trend-focused: Show trends over time, not just snapshots
- Actionable: Every metric should suggest what to do if it goes red
- Automated: Data collection must be automatic, not manual
- Living: Update in real-time or at least daily
Tools for QA Dashboards
| Tool | Best For | Cost |
|---|---|---|
| Grafana | Custom metrics, CI/CD data | Free (open source) |
| Allure TestOps | Test execution tracking | Paid |
| Google Sheets | Simple, quick, shareable | Free |
| Jira Dashboard | If team already uses Jira | Included |
