Build vs Buy Decision
❌ Don't Build From Scratch When:
- • Common use case (search, weather, calculations)
- • Open-source alternatives exist
- • Time-to-market is critical
- • Small team or limited resources
✓ Consider Building When:
- • Proprietary internal systems
- • Unique business logic required
- • Security/compliance constraints
- • Performance optimization needed
