ABSTRACT
Knowing the existence of mismatches between reality and formality is the first step for better remedy. Enforcing rules without understanding the mismatches is not an effective remedy. Appropriate monitoring mechanisms are a prerequisite for knowing the existence of mismatches. So are appropriate evaluation mechanisms for understanding mismatches. These mechanisms should maintain independence from and authority over administrative mechanisms. Respecting humans at the front end (e.g., operators, maintenance persons) is also a useful step towards better remedy. They are the ones who best know the demanding reality, and how to cope with it. Overall safety has to be ensured by evaluating their behaviors, and corrective actions must be taken if their reactions are too risky.
