4 metrics:
- Lead time
- Release frequency
- Time to restore
- Change fail rate

CD:
- Lowers lead time, increases release frequency, lowers time to restore
- Charity's connections

Test(-driven development) and CI:
- Lowers change fail rate
- Builds confidence in CD

Observability:
- Lowers time to restore
- Builds confidence in CD

Monitoring:
- Lowers change fail rate (e.g., fix before escalation)
- Informs testing/CI

Peer reviews:
- Lowers lead time, (indirectly) increases release frequency
- Informs testing/CI

Feature flags:
- Increases release frequency, lowers time to restore
- Builds confidence in CD
- Reduces blast radius from lack of testing/CI

Automation:
- Enables CI, CD, monitoring

Architecture:
- Improves testing
- Accelerates peer reviews
