The quality of your products and services usually depends heavily on the raw materials, intermediate products and other external services used. Incoming goods inspections can certainly catch many errors, but they cost money. Does this even detect all possible defects? The necessary complaint processing is also an important cost factor. And can you afford to wait for replacement deliveries?
In order to control these risks, Chapter 8.4 of ISO 9001 therefore requires that you ensure that the goods and services supplied or processes outsourced meet your requirements. In addition to checking supplier output, process or system audits at the supplier’s premises are an effective means of doing this.
