Exit Safe Launch / Exit PPAP-permanent plant closure

[OLDQCNANA]

Hello All! Help!
Looking for advice related to this new thing called an Exit PPAP. We are IATF16949 Automotive. Where does it state this as a requirement? Could not locate in IATF or AIAG. Suddenly our customer is requesting this document. We have less than 7 weeks to go for permanent closure. The only thing I see is the CSR is to keep long term SPC data. We have the Data, but it is not formatted in Minitab. We are meeting all specifications.

What period of time is considered to be used for "long term data"? Since our inception in 2012 to date? How do you perform this and determine what is used for long term data?

In addition, they have CPK 1.67 for PPAP and then 1.33 Cpk and 1.0 Ppk for different specifications as ongoing production. I am still confused about Ppk vs Cpk regardless.

Are you transferring product to another location? Ford and Lear appear to require exit PPAPs for product transfers. Here is an OLD thread about Exit PPAPs.

Long term data will partial depend on the volume. It is typically several months, but if you only run a product infrequently, it could be more. The key is to include multiple setups. Cp/Cpk is from short-term data (single setup). Pp/Ppk is from long-term data. There are differences in the calculation methods also. Cp/Cpk uses the within subgroup variation while Pp/Ppk uses the overall within/between variation.

No transfer other than warehouse to hold finished product.

Does this mean that your entire company is going out of business and no one will make that product in the future? And you are returning the tooling to the customer?

 

[OLDQCNANA]

Yes, the US facility is going out of business. Customer has another company in MX that they have previously sourced to make product. There is no tooling that will be transferred.

In cases like this the customer wants the Exit PPAP as reference, both for the new supplier as well as for problem-solving if the run into issues with the new supplier. For example, you may have been running a certain characteristic in the upper portion of the spec. New supplier starts providing material toward the lower end of the spec and a problem arises. The customer can now compare your Exit PPAP with the new suppliers PPAP and see the difference.

I guess part of my thoughts are why we should help out this new supplier customer already has, when that's the reason were shutting down....

Well, that is a business decision. If your entire company is going out of business, you don't have much to lose. However, if this is just one location and the company itself is remaining in business, they may not want to burn bridges with this customer and jeopardize future business.

If you're not transferring tooling and they are moving parts to a supplier in MX, I don't think there is much for you to worry about. Just wait them out. What are they going to do?
