For the IATF 16949 section 8.4.1.2, Supplier Selection Process, a question that frequently comes up is what is the scope of suppliers that should be included in this process. For example, do all of our providers need to be a part of this process? Do providers of services, such as a third party sorting company, need to be a part of this process? Is there a definition somewhere that defines what type of suppliers need to be a part of the definition of external providers?
