Retrospective Highlights
What Went Well 🎉
- Pair programming on deposit logic reduced bugs (0 defects found in QA!)
- Early stakeholder demo (Day 7) caught UX issue before full build
What Could Improve 🔧
- Database migration delayed US-047 by 3 days → Plan migrations earlier
- Last-minute design change to modify modal → Lock designs before sprint
Action Items
- [ ] Jordan: Set up DB migration review process
- [ ] Alex: Start design review 1 week before sprint planning
Key Learnings
Technical:
- Stripe's incremental authorization API required extra validation (not documented well)
- Real-time availability check added 200ms latency → Added caching (30-second TTL)
Product:
- Users want to modify date too (not just time) → Add to backlog as US-048
