Reliability Practices
Operational habits that keep deployment velocity and resilience in balance.
- Error budget policy pauses risky releases when burn rate spikes.
- Synthetic checks validate critical user journeys before and after rollout.
- Incident postmortems feed runbook updates and measurable prevention actions.
- Reliability work is tracked alongside feature work, not treated as optional debt.
