Worked Example — Inspection Result Logic
Cleaning inspection, Zone C, 5 standards in scope:
- • 4 answered YES
- • 1 answered NO — AOS-CLN-004 (CRITICAL), washroom cleaning standard not met
Result: FAILED
No percentage is calculated. A CRITICAL failure fails the inspection immediately, and the finding stays open across shift boundaries until closed.
