NPQP - Ground Rules of Document Submission
- Nissan Product Quality Procedure (NPQP) utilizes electronic documentation. Some of these documents require the signature of the supplier representative.
The supplier shall agree the document sign off requirements with Nissan. - If the supplier uses their own document format, which has been agreed with Nissan, the header portion of the supplier document shall include the same information
as the corresponding NPQP document. - If the content of a document that was submitted to Nissan is revised, the supplier shall resubmit the revised document together with a "Document Revision Record".

The part family shall be agreed between Nissan and the supplier. - Where a document has been completed for a part family, a separate list of applicable part numbers shall be completed using the Part Number Details (PND) format below
and attached to the document.
