We are doing two similar parts for two different customers.To avoid any mixup we requested both the customers to allow some identification on the part , but the customers are not relenting? What other methods acn be adpoted to avoid mixup?

Keep the parts seperated. Don't process them on adjacent machines. Seperate the production scheduling as much as possible. After processing one of the parts, use strong housekeeping programs to ensure none of the first part are left at the process station.

If the visual identification and mixing of paperwork is an issue, use different colored paper or bin labels.

We find our biggest problem area in this regard is not cleaning up the work area completely. We have the procedures, training, fail safes, and set-up sign-offs in place to ensure we clean up, but guess what. I guess we need to come up with a way to make the process get up, walk out to the parking lot, and brush itself off.

Oh well, someday maybe.
