Dear Khun Tawatchai,
Thank you for your management.
As we mentioned yesterday, overtime working should be managed properly.
For PM, please consider the idea like following,
A: Highest priority, if machine is broken, need to stop main assembly line and take a long time to recover.
B: Higher priority, if machine is broken, need to stop main assembly line but can recover in short time.
….so on
These are just example, and please consider and discuss how to prioritize PM activity.
We understand sometimes we need to do Overtime working for PM because some PM cannot be done when the line is operating to produce trucks.
Please consider priorities carefully because PM is so important for the factory operation.
Best regards,
