Development metrics — quick notes
| Measure | Signals |
|---|---|
| PR cycle time / time to first review | Usually the largest hidden delay |
| PR size | Large PRs get worse review |
Build failure rate on main | Trunk health |
| Code churn | Unsettled design in that area |
Misleading metrics: lines of code · commits per developer · individual velocity — all measure an individual's output, so helping a colleague lowers your score.
Trap: optimising the two-minute build while an eleven-hour review wait sits unmeasured.
