maybe I am to much of an engineer and react to a human failure with the same process as I would with an equipment failure.
If a high capital piece of equipment fails you would have a look at its use and maintenance.
Has its use exceeded its design.
Has the maintenance been lacking or out of schedule.
If a parameter has been exceeded suitable remedial maintenance will be performed and then the unit put back into service with increased monitoring to prevent failure again.
Quite often you find that it becomes the most dependable bit of plant in the factory.
