Hi There,
One of our customers has set their acceptable DPPM level at 5K, for all their suppliers.... across the board.
The problem is we send them about 20 different p/n's totaling 130 pcs per month. The parts are extremely high tolerance machinings and inevitably one (or more) will be found out of tolerance (by .0001") in a month’s time.
I've been attempting to persuade their Global Quality Director that this DPPM requirement does not fit the highly complex low volume product type we manufacture for them. Not going to far with this.
Is there a standard minimum qty that must be measured before DPPM can be accurately calculated? Something I can throw back that might assist me in my effort?
Thanks - Brookway
