Re: Customer Supplier Manuals and TS 16949 Audit
Our automotive customers are a small percentage of our total customer base. Our quoting process consists of acquiring customer requirements that they state must be meet. (Hardness, straightness, etc). If they want us to follow a specific document, whether it is their supplier manual, customer drawing, etc then they must make it know to us.
Our customers are perfectly happy with the work we are doing for them. If they did not feel it necessary to require the use of a “Supplier Manual” (SM) then that is their choice.
Again, now that we know that an auditor will make an issue of this we will address this in the quoting process. It is a very good idea to ask this because the customer may not know if it is necessary or not. IT is always good to be aware of documents that are “hanging out there” that could become an issue later.
One of the customers that we asked about the SM had forgotten that they even had one!
There are many “things” that could be asked and that may not be told to us by the customer. We have some obligation to ask but the customer also has a responsibility to give us all pertinent info and requirements. We try our best to get as much information from them as possible but we are at there mercy.
AS for this audit, the requirement to use SM was not in evidence on purchase orders or in customer quotes.
I believe (whether it is good practice or not) the auditor should not make a determination that we should have asked or that the customer should have told us.

Jim, you are correct from a contractual/legal perspective. It could be one of those cases where the customer has a bad process of clearly invoking all of the requirements associated with a purchasing order or contract.
Many times, a supplier quality manual gets issued and/or revised, and the contractual instrument used in a long term agreement never gets changed to reflect the fact that the supplier manual is now part of the requirements.
Once again, while the supplier might be "covered" from a legal/contractual point of view, if they fail to abide by the supplier manual requirements, now invoked by the customer, they might lose the business altogether.
It is "concerning", imho, when an external auditor knows about the existence of supplier manuals and the suppliers don't. Shouldn't the supplier be very aware of documents such as these? The existence of such documents should be no surprise to the supplier when they have a good working relationship with their customers.
