Measure to improve
Metrics help communicate the state of quality and make decisions. They are not meant to 'score' people, but to give objective visibility of progress and risk.
| Metric | What it indicates |
|---|---|
| Defect density | Defects per size/module |
| Defect leakage | Defects that reached production |
| Requirements coverage | % of requirements with tests |
| Pass rate | % of cases passing |
Be careful using metrics as goals in themselves: optimizing a number can worsen real quality (e.g. closing bugs without solving them to improve the pass rate).
