Presses 7 and 12. ERP job log.
Job switches still as slow as before any change
What it shows: The ERP shows when each old job ended and when the next job made its first good part.
Why it proves the point: The six average 71 minutes, close to the 70 in the ERP before any change, so no job switch is faster yet.
