Starting to get Involved
I am interested in thoughts/opinions/best practice when calculating PPM and filtering out defects from the calculation.
Situation: We calculate Supplier PPM each month based on quantity of parts written up on nonconformance reports during the month against quantity of part reciepts for the month. Period.
I have been asked to remove all the defects where the disposition of the nonconformance was "Use As Is".
In my opinion these should still be part of the PPM calculation. Regardless of the disposition, we had nonconforming product.
Thoughts or comments please.
