On-site Supplier Audits

In my recent post in March on Supplier Evaluations, I addressed supplier self-assessment questionnaires.  Questionnaires are good, but sometimes it is good to visit the customer.  What should one do when on-site at the supplier?

A client recently asked me how to conduct an on-site process audit of a supplier.  He was visiting the supplier anyway, so it made sense to him to conduct a process audit while there.

When doing such an audit, I like to start with known purchase orders (open and closed) and follow those orders from the point where the PO is received by the supplier to the point where the product ships.  Asking the supplier to retrieve records about a closed order also helps to assess the supplier’s record keeping.

To assist the client, I came up with 10 areas of questioning.   The questions follow a customer purchase order through the sales order, design, procurement, production and inspection processes.  They offer a pretty good idea about the supplier’s processes and how well aligned with the standard they are.  Such an audit can be conducted in a couple of hours and give a pretty good idea of the supplier’s compliance with ISO 9001 requirements.
