GM Design Validation Vs Product Validation, what do they mean

[sundarun]

Hi,

I am new to this forum.

I seek assistance in understanding the difference between Design validation & Product Validation in GM's terms.

Common sense gives an explanation of the difference between these 2, however what is specifically meant by GM?

Thanks in Advance.

Welcome to the forums.
I am not an expert but the matter ios refered to in GM 1927 Global SQ Manual
in Gate 11

Task Description: The purpose of the GP-11 activity is to assemble and test production intent parts, assembly systems and vehicles for design and assembly validation. Part approval at GP-11 will ensure part problems are identified and corrected in order to minimize the impact of part variation upon design evaluation, manufacturing, and assembly. The GP-11 activity encompasses the suppliers’ Analysis/Development/Validation (ADV) plans. The specific type of GP-11 requirements will be listed in the SOR (i.e., GP-11, GP-11 ADV Design Validation [GP-11 ADV-DV] and / or GP-11 ADV Product Validation [GP-11 ADV-PV]). The suppliers’ validation plan and DFMEA requires approval by the GM Validation Engineer.

Deliverables:
• Serialized parts with GP-11 documentation
• Approved DFMEA and GP-11 ADV-DV and/or GP-11 ADV-PV plan for commodities specified in the SOR

Methodology:
• Pre-prototype and prototype parts are made to GM authorized drawings, templates, models, and/or other engineering design records.
• Parts are numerically serialized and referenced to test/inspection results.
• A complete characteristic inspection is performed on three (3) parts, unless different quantities are specified by the procuring division.
• A key product characteristic (KPC) inspection is required on all parts for any KPC identified in the design record.
• A material certification is obtained to provide evidence of compliance to GM product specifications.
• A GP-11 warrant is completed for each part number and shipment to GM.
• Design and/or Product validation (ADV-DV and/or ADV-PV) is required when specified in the Statement of Requirements (SOR).
• The ADV-DV and/or ADV-PV plans and results are submitted to the GM Validation Engineer for approval prior to shipment.
• Suppliers’ submission requirement will be specified by the procuring division in the prototype purchase order. Reference GP-11, section 2.0 for submission requirements when not specified.
• Suppliers must ensure that all subcontractors follow the requirements defined in GP-11 or equivalent.

I hope this helps
