this.phases = []; this.metrics = { errorRate: 0, responseTime: 0, userCount: 0, conversionRate: 0 }; } createPhases(strategy) { return [ { phase: 1, name: 'Canary', rollout: '5%', duration: '2 hours', successCriteria: { errorRate: '<0.1%', responseTime: '<2s', conversionRate: 'No significant change' }, gatekeeper: 'Automated checks + human approval' }, { phase: 2, name: 'Early Access', rollout: '25%', duration: '4 hours', successCriteria: { errorRate: '<0.2%', responseTime: '<2.5s', conversionRate: 'No drop' }, gatekeeper: 'Manual verification' }, { phase: 3, name: 'General Availability', rollout: '100%', duration: 'Ongoing', successCriteria: { errorRate: '<0.1%', responseTime: '<2s', businessMetrics: 'Targets met' }, gatekeeper: 'Continuous monitoring' } ]; } monitorRollout() { return { metrics: { errorRate: this.getErrorRate(), responseTime: this.getResponseTime(), userCount: this.getUserCount(), conversionRate: this.getConversionRate() }, health: this.calculateReleaseHealth(), alerts: this.checkForAnomalies(), recommendation: this.getRolloutRecommendation() }; } calculateReleaseHealth() { const checks = [ this.metrics.errorRate < 0.1, this.metrics.responseTime < 2000, this.metrics.conversionRate > -5, this.metrics.userCount > 0 ]; const healthScore = (checks.filter(Boolean).length / checks.length) * 100; return healthScore > 80 ? 'Healthy' : 'Degraded'; } } ``` ## 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
