Nielsen's Heuristic .05 — Haiku Edition

Error Prevention, the fifth heuristic in Nielsen’s UX framework, is built on a simple insight: the best interface is one where mistakes don’t happen in the first place. Good design anticipates slips and prevents them with constraints, confirmations, and clarity. From destructive action safeguards to form validation, this principle favors thoughtful defaults over error messages.

Through a quiet haiku and metaphor of movement without misstep, this poster reminds teams that the most elegant fix is the one never needed.
