Re: System corrective actions when conforming product depends heavily on inspection
It really depends on the industry that you are in, as well as the severity of the consequences of the defect.
If it is not very critical, sometimes we will place a picture of the defect at the workbench and include this in the Attribute G R&R tests (short method) for the inspectors involved in inspections.
However, you must note that visual inspections are only 70%-80% effective. Perhaps the low ppm is due to visual inspectors not being able to pick up these defects effectively?
Any sound corrective actions will try to improve the process up front.
If we are requiring visual inspectors to stay alert for a 2ppm defect, it will place undue pressure and may affect the output in the end.
Just my two cents
