Per AS9100, we are supposed to maintain an approved list of suppliers. I have always assumed that this requirement only applied for vendors that directly impact product quality (e.g., raw materials providers, manufacturers, processors, etc.); however, I am wondering if this requirement is more broad in its reach. In particular, I need to know if the following types of vendors need to be added to the approved supplier list.
- Machine Maintenance Service Providers
- Machine Vendors
- Software Vendors (e.g., ERP)
