# Project: E-Commerce Platform Migration
Date: 2024-01-15
Duration: 3 months
Team Size: 8 people
## What Went Well
✓ **Incremental Migration Strategy**
- Reduced risk by migrating one service at a time
- Maintained system stability throughout
- Learning: Gradual transitions work better than big bang
✓ **Daily Sync Meetings**
- Caught issues early
- Maintained team alignment
- Learning: Consistent communication prevents surprises
✓ **Automated Testing Investment**
- Caught 95% of bugs before production
- Gave confidence for refactoring
- Learning: Upfront test investment pays dividends
## What Could Be Improved
✗ **Underestimated Complexity**
- Data migration took 2x longer than planned
- Learning: Always buffer 50% for unknowns
- Action: Create complexity assessment framework
✗ **Documentation Lag**
- Docs updated after implementation
- Caused confusion for other teams
- Learning: Document as you go, not after
- Action: Add docs to Definition of Done
✗ **Performance Regression**
- New system 20% slower initially
- Not caught until production
- Learning: Performance tests in CI/CD pipeline
- Action: Implement automated performance benchmarks
## Key Insights
1. **Communication > Documentation**
- Face-to-face solved issues faster
- But document decisions for future reference
2. **Small Wins Build Momentum**
- Early successes motivated team
- Celebrate incremental progress
3. **Technical Debt Compounds**
- Old shortcuts made migration harder
- Address debt continuously, not later

Problem: Production deployment failed
Why? → Database migration script failed
Why? → Script assumed empty tables
Why? → No check for existing data
Why? → Migration testing used clean database
Why? → Test environment doesn't mirror production
Root Cause: Test environment divergence
Solution: Use production data snapshot for testing
## Event: Critical Bug in Production
Date: 2024-01-10
### What was supposed to happen?
- Feature deployment with zero downtime
- Gradual rollout to 10% of users
- Monitoring for issues before full release
### What actually happened?
- Deployment succeeded initially
- Bug affected 100% of users immediately
- 2-hour outage while rolling back
### Why were there differences?
1. Feature flag configuration error
2. Insufficient test coverage for flag logic
3. Monitoring alerts not configured for new feature
### What can we learn?
1. **Test feature flags explicitly**
- Add flag configuration to test scenarios
- Verify gradual rollout behavior
2. **Pre-configure monitoring**
- Set up alerts before deployment
- Test alert triggers in staging
3. **Deployment checklist update**
- Add feature flag verification step
- Include monitoring setup confirmation
## Technical Growth Reflection
### Skills Developed
- **System Design**: Can now design distributed systems
- Evidence: Successfully architected microservices
- Growth path: Study more advanced patterns
- **Performance Optimization**: Improved code efficiency
- Evidence: Reduced latency by 60%
- Growth path: Learn more profiling tools
### Areas for Improvement
- **Communication**: Technical concepts to non-technical audience
- Challenge: Executive presentation confusion
- Action: Practice simplified explanations
- **Time Estimation**: Consistently underestimate by 30%
- Challenge: Optimism bias
- Action: Track estimates vs actuals, adjust
### Key Learnings
1. **Simplicity wins**: Complex solutions often fail
2. **Ask questions early**: Assumptions are dangerous
3. **Document decisions**: Future self will thank you
4. **Test in production**: Nothing beats real-world validation

## Failure Analysis: [Incident Name]
### Timeline
- T-24h: Configuration change deployed
- T-0: First error detected
- T+15m: Alert triggered
- T+30m: Root cause identified
- T+45m: Fix deployed
- T+60m: System recovered
### Contributing Factors
1. **Technical**: Race condition in cache update
2. **Process**: No code review for config changes
3. **Human**: Engineer unfamiliar with system
4. **Organizational**: Understaffed during incident
### Lessons Learned
1. Config changes need same rigor as code
2. Knowledge silos are dangerous
3. Automation could have prevented this
### Action Items
- [ ] Add config validation pipeline
- [ ] Implement buddy system for critical changes
- [ ] Create runbook for this scenario
- [ ] Schedule knowledge sharing session
