Unit synchronization

Risk

Units do not synchronize (sync failure)

Costs of delay

If the system operation depends on coordination, and the units that need to coordinate are not synchronized, the results might be an incidence.

Example

Therac-25

Prevention

Disable operation dependent on the synchronization

Protection

Notify the operators about the synch progress and the remaining time

Notify when the elapsed time surpasses a likelihood threshold

Implementation

• Define rules for sync dependent activity
• Notify the operators about delays.
