Tony S said this on another thread and now im thinking. Control of documented information applies to: those that your organization needs to "maintain" - i.e. documented information that support the operation of the processes (e.g. procedures, instructions, etc.; those that your organization needs to "retain" - i.e. documented information that provide evidence of conformity with requirements (i.e. records) Some of my customers require a CoC, This specific customer simply does not want one or care to have one, the product we send them in nature is virtually impossible to have a visible defect on it. Can my SO/PO be considered a Record of documented information that provides evidence of conformity with requirements. We Still inspect and audit for appearance and mechanical operation. The customer has never returned or complained about the quality of the product. (we ship hundreds a week) If not do i have to create/retain a separate inspection form to prove that is in fact conforming with requirements.
