APQP - Is the APQP process supposed to include process changes?

[Kevin Tan]

Hi all,
This may seem to be a naive question, but is the APQP process supposed to include 'process change' as well, as opposed to only introduction of (or changes to) a new product.

By process change I mean changes in work / manufacturing method, which does not affect the design record (drawing, BOM, etc).

I couldn't find clear references to 'process change' in APQP manual. But I know this is included in PPAP.

Thanks in advance for your kindly assistance.

Hi Kevin!
In the QS9000 3rd Edition, 4.9.5, you are to maintain records of process change effective dates - and consult your customer for submission requirements.

In 4.5.2.1, it mentions customer originating changes and the need for an updated PPAP.

Most importantly, in 4.2.3.1, it states convening multi-diciplinary teams to prepare for production of changed products. These teams should use appropriate techniques identified in the APQP manual (or similar techniques that accomplish the intent).

When you change a process, don't you want verification that the product has not changed negatively? So prove it, utilizing the appropriate methods listed above.

Yeppers...

In fact, I have an "APQP Checklist" that has a specific section for "Product/Process Changes" and such. SEE APPENDIX A IN THE BACK OF THE BIG 3'S APQP REFERENCE MANUAL.

It all boils down to the significance of say, for instance, if you don't switch work from a piece of equipment, but relocate that piece from one end of your shop to another --> you have to evaluate the potential impact to the processing of said product... sad to say, but true.
