Delivery metrics — quick notes
| Metric | Signals |
|---|---|
| Deployment frequency | How often value ships |
| Change failure rate | Share of deployments causing failure |
| Time to recovery | Speed of recovery |
| Lead time for changes | Commit → production |
- Frequency alone is gameable — pair it with change failure rate.
- Rising frequency + flat failure rate = real improvement.
- Smaller batches reduce risk: less change per release, easier to attribute and reverse.
- Halving recovery time is usually cheaper than halving failure rate.
