Thank you for your information.
I can understand that the operator was trained appropriately in the OTH OJT system.
By the way, I found the go / no go standard in the evaluation sheet that 40% or over of the total points is evaluated as “passed”.
Isn’t it too low to give the “pass” with 40% of the total points?
It means that the operator might make mistakes at the rate of 60%, but it is acceptable in the OTH system, doesn’t it?
