An OEM makes a part that is sold to for End Use in some other guise (possibly in addition to being offered commercially by the OEM itself). In our context, the original part might (for example) be part of some next-higher assembly, or might be designated for our purpose as an interchangeable part by a VICD, having customer-owned verification data driven by the customer-unique requirements in an SCD, or modified by an Altered Item Drawing.
