# Review Checklist

Systematically verify every required step before signing off on a process.

## Why This Is Best Practice

**Adopted by:** Aviation (FAA), surgery (WHO), NASA, nuclear power (NRC).
**Impact:** WHO Surgical Safety Checklist reduced surgical complications by 36% and deaths
by 47% (Haynes et al., NEJM 2009).
**Why best:** Human memory under time pressure is unreliable. External checklists eliminate
recall failures.
