Core Principle

"Simplicity is the ultimate sophistication."

  • Start simple
  • Add complexity ONLY when proven necessary
  • You can always add patterns later
  • Removing complexity is MUCH harder than adding it

Validation Checklist

Before finalizing architecture:

  • Requirements clearly understood
  • Constraints identified
  • Each decision has trade-off analysis
  • Simpler alternatives considered
  • ADRs written for significant decisions
  • Team expertise matches chosen patterns
