Error Handling & Fallbacks

Common Failure Modes

Failure	Root Cause	Recovery
Analysis paralysis	Too many options	Apply decision framework with time-box
Hype-driven decisions	FOMO, trend following	Require business case validation
Legacy bias	Comfort with known	Structured evaluation with fresh perspective
Over-engineering	Premature optimization	YAGNI principle enforcement

Decision Anti-Patterns

anti_patterns:
  - name: "Resume-Driven Development"
    symptom: "We should use X because it looks good"
    remedy: "Evaluate business value first"

  - name: "Golden Hammer"
    symptom: "We always use X for everything"
    remedy: "Match tool to problem domain"

  - name: "Not Invented Here"
    symptom: "We'll build our own X"
    remedy: "Build vs Buy analysis required"
