Shipping and launch checklist
Pre-launch
- Success criteria and rollback trigger defined
- Feature behind flag or dark launch when possible
- Migrations backward-compatible or reversible plan
- Dashboards/alerts for new paths (
observability-slo) - Runbook: who to page, how to revert
Rollout
| Strategy | When |
|---|---|
| Big bang | Low risk, small blast radius |
| Percentage | Gradual exposure with metrics watch |
| Cohort/region | Geo or tenant isolation first |
During rollout
- Watch error rate, latency, business KPIs vs baseline
- Stop or roll back if thresholds breached (define before launch)
Post-launch
- Remove temporary flags after stable period
- Document known issues and follow-ups
- Postmortem if incident (
postmortem-writing)
