Stack Compatibility Check

| Yeni Tech | Mevcut Stack | Uyumluluk | Risk |
|-----------|-------------|-----------|------|
| [Tech] | Node.js | Uyumlu | Düşük |
| [Tech] | PostgreSQL | Adapter var | Orta |
| [Tech] | Docker | Native support | Düşük |

Migration Prioritization

Checklist

• Her büyük tech kararı ADR ile documented
• Radar quarterly güncelleniyor
• Hold ring'deki tech'ler migration planında
• Yeni tech 8-dimension evaluation'dan geçmiş
• Stack compatibility check yapılmış
• PoC results documented
• License uygunluk kontrolü

Anti-Patterns

• Resume-driven development (CV için tech seçimi)
• Shiny object syndrome (her yeni framework'u deneme)
• Evaluation'sız tech adoption
• ADR yazmadan büyük karar
• Hold'daki tech'i yeni projede kullanma
