Contingency training equips users with defined procedures to check and respond to exceptional conditions during disruptions, reducing exploitation of mishandled errors.

Performing IR tests ensures exceptional conditions are properly checked and handled to enable effective response.

Mandates explicit, predictable handling of exceptional conditions rather than undefined continuation.

Requires systematic prediction and handling of failure conditions, reducing the impact of unhandled exceptional states.
