This chart depicts that the design focus should depend on the operational situation, as follows:

• In designing the routine operation, the focus should be on slip prevention
• In designing the behavior in alarm conditions, the focus should be on exception detection
• In designing the behavior under hazard, the focus should be on optimizing the operational procedures for easy troubleshooting
• In designing the behavior under threat, the focus should be on restricting the procedures to a safe-mode operation.
