So I recently got into a leadership role for Quality Control. Production line is very good, but...
You see, the production manager, also very proficient in the field of Quality, has made the next process reliant on the previous process, so that the whole thing becomes a fault-free product at the end.
But the thing is... we are currently using about 40% of our production capacity, and next month, we are going 100%... and here's where I'm worrying.
If in 300 pieces per day, there are like 10 reworks done by the next station, that would mean about 40 reworks at 100%... not to mention the energy of the workforce dropping as the time passes by (we currently shut down at 4PM, but we are planning to increase the working hours to 7PM for full scale manufacturing) which would lead to more faults, as I have studied.
Here is where I'm worried about: what if the workers miss these reworks and it show up in the final product? I've raised this concern to the Production manager, he said that in about 5 years of working, we had zero issues with the customers. I've already checked the records, and it's correct.
Am I overthinking this? If all is well, what should I do?
I have Quality Control and Laboratory under my domain. Just yesterday, we got a grade level up, complying with IATF16949.
