PLM non-implementing change (see also implementing change)

A non-implementing change form does not release or cancel anything, but simply announces a particular fact about the affected items listed on it. A "fact" may be, for instance, that a document needs revision ("change request"), or product shipments must be stopped until a defect is corrected ("stop ship"), or an unapproved component can be used as a temporary substitution ("waiver"). Even when approved, none of these change forms will release or cancel an item.
