const checks = [
this.metrics.errorRate < 0.1,
this.metrics.responseTime < 2000,
this.metrics.conversionRate > -5,

Best Practices
✅ DO
- Plan releases with clear timeline and milestones
- Communicate early and often with stakeholders
- Test thoroughly in staging environment
- Use phased rollout to reduce risk
- Monitor metrics continuously during rollout
- Have clear rollback procedure
- Document all changes and decisions
- Conduct post-release review
- Include support team in planning
- Plan releases during lower-traffic periods
❌ DON'T
- Release without adequate testing
- Deploy Friday afternoon
- Release without monitoring in place
- Skip UAT/acceptance testing
- Release all major changes together
- Deploy without rollback plan
- Surprise customers with breaking changes
- Release without support team readiness
- Make unreviewed last-minute changes
- Ignore performance or error metrics
Release Planning Tips
- Phased rollouts reduce blast radius from 100% to 5%
- Monitor first 2 hours critically, then every 30 min
- Have incident commander on call during rollout
- Document lessons learned for next release
- Celebrate successful releases with team
