PRE-PRODUCTION PART QUALITY PROCESS (PPQP)

PRE-PRODUCTION / PROTOTYPE Version 6

SUPPLIER REQUIREMENTS GUIDELINE

GM Confidential

Introduction

The PPQP SUPPLIER REQUIREMENTS GUIDELINE specifies the General Motors global minimum part quality certification

requirements for Pre-Production/Prototype/Production parts that have not received full PPAP (Production Part Approval Process)

approval for use in design intent Pre-Production Builds at General Motors.

All PPQP Pre-Production/Prototype part quality supplier warrant certification shall be in accordance with the requirements set forth in

this PPQP Supplier Requirements Guideline.

The term “Supplier” shall be used to indicate the prime contractor (Tier 1 Supplier) to General Motors Corporation. Tier 1 Suppliers are

responsible to apply the PPQP Supplier Requirements Guideline to subcontractors (Tier 2 Suppliers).

GM PPO Supplier Quality may request suppliers to provide additional control evidences not specified in this document.

Pre-Production Part Quality Process – Key Points

1. PPQP classifies Pre-Production/Prototype parts that have not received full PPAP approval being used in Pre-Production builds

into two categories:

a. Pre-Production/Prototype “CRITICAL” parts

b. Pre-Production/Prototype “NON-CRITICAL” parts

2. The category of the part and conformance to General Motors specifications determines approval requirements.

3. Suppliers must utilize the following new forms, labels and tags available via GM Supply Power in accordance with the new

PPQP process: PPQP-1 (Quality Warrant), PPQP-2 (Corrective Action Plan), PPQP-3 (Pre-Production part tag), PPQP-4

(Container Label), PPQP Non-Conforming Part Approval Email Process. PPQP-5 (Body Stamping/Sub Assemblies

Supplement) (When in Supply Power: Select the “Document Library” tab, then select “Supplier Quality” folder, then select the

“Procedures and Forms” folder, then select “Global Pre-Production Part Quality Process (PPQP)”).

4. PPQP labels and tags are available for supplier purchase from CMS Print Solutions via the “CMS/Supplier Portal” link on the

GM SupplyPower website home page. Contact your regional GM procuring location for local suppliers.

5. Electronic copies of the PPQP-3 and PPQP-4 tags and labels are available for suppliers who prefer in-house printing in lieu of

purchase via GM SupplyPower in the Quality Document Center, Procedures and Forms, PPQP Process folder.

6. All shipments to PPO sites without proper documentation or without previous agreement with PPO Supplier Quality will be

quarantined pending resolution and payment will be withheld until necessary documentation is received by GM.

7. Documentation issues that are not rectified within 24 hours may lead to the issuance of a Problem Reporting & Resolution

(PR&R).

8. The supplier is required to retain all original PPQP documentation (including dimensional inspection and material reports) for a

specified model year for two (2) years after the last shipment and is obligated to provide copies to GM upon request.

9. Suppliers with questions relative to the identity and email address of the respective Program Subsystem Validation Engineer

(PSVE) for Vehicle or Design Release Engineer (DRE) Powertrain, should contact the respective Program or Account

Manager assigned to the part within their company.

PRODUCTION APPROVED PARTS:

copies of all associated test reports shall also be submitted with the shipment.

PPQP CRITICAL PARTS

1. The Request for Quote and Purchase Order will identify Critical Parts based on the Program Specific Critical Parts List.

2. GM PPO Supplier Quality (for Vehicle and Brazil) / DRE (for PPO Powertrain) must approve the checking strategy

(checking fixtures, holding fixtures, etc.).

3. GM PPO Supplier Quality (for Vehicle and Brazil) / DRE (for PPO Powertrain) must approve the first (1st) batch of Critical

parts before it is shipped to General Motors. The supplier is required to provide the inspection data regardless of

conformance to the design record.

4. When supplier checking strategy proposal is ready, the supplier shall contact GM to schedule approval. The

supplier shall obtain GM approval prior to beginning construction on checking devices.

When the first batch of parts is ready for shipment to GM, the supplier shall schedule review with GM

representative and gain approval from GM prior to shipping parts/components to the build site. For Powertrain,

the DRE is the GM representative referenced above. For Vehicle Assembly and Brazil the GM representative

must be PPO Quality.

5. Supplier is responsible to ensure all documentation is accurate and complete before scheduling the first batch review.

6. The GM Release Engineer and PSVE will support GM PPO Supplier Quality and the supplier providing technical expertise

when required.

7. Subsequent shipments of Critical Parts, without Corrective Action Plans, shall be inspected and self-certified by the supplier.

8. In all cases, the GM Release Engineer and PSVE (for Vehicle and Brazil) / DRE (for PPO Powertrain) must approve the

Correction Action Plan for ALL nonconforming parts prior to shipment to GM. (Refer to Key Points Item #3 Non-Conforming

Part Approval Email Process)

9. Suppliers must submit each NON-Conforming Part Quality Warrant, Corrective Action Plan and supporting documentation via

a dual addressed email to:

a. For vehicle: the GM Release Engineer and the PSVE, simultaneously for their respective review and approval.

1.1 PPQP-1 Part Quality Warrant / PPQP-2 Corrective Action Plan Form

The PPQP-1 Part Quality Warrant form is a document which

contains the part identification, dimensional status, material

specification compliance and functional data about the submitted

Pre-Production/Prototype part. The Part Quality Warrant must be

completed in full and signed by an authorized Quality Engineer or

Product Engineer at the Supplier who is responsible for the stated

quality certification. There shall be a separate Quality Warrant

form for each part number shipped to General Motors. All parts

are to be made to GM authorized drawings, templates, models

and/or other engineering design record, using specified material.

If parts do not meet GM specifications, but are deemed usable for

Pre-Production/Prototype use, the Supplier must also complete in

full a PPQP-2 Corrective Action Plan form. The completed

PPQP-2 Corrective Action Plan form and the completed PPQP-1

Part Quality Warrant along with supporting documentation

(inspection results, test reports, marked drawings, etc.,) must be

submitted via a dual addressed email to both the GM Release

Engineer and the PSVE for vehicle and the Systems Engineer

and the Lead Design Release Engineer / Lead Engineer for

Powertrain per the Non-conforming Part Email Process

referenced on page #3. The PPQP-1 Part Quality Warrant as

well as the approved PPQP-2 Corrective Action Plan form is

then sent with the shipment of parts.

The PPQP-1 Part Quality Warrant document shall be printed

using blue paper. The Warrant and Corrective Action Plan shall

be affixed to the outside of the container and a duplicate shall be

inside the container.

1.2 2D Simplified Drawing

A copy of the 2-D Drawing (Figure 1: Manual or Figure 2:

electronic output) shall be provided with the PPQP-1 Part Quality

Warrant for all initial shipments and subsequent shipments if the

parts were run at the same time, with the same setup etc. The 2-

D Drawing shall be properly mapped as per the level of

manufacturing of the referred Pre-Production/Prototype part, so

that the analysis of information included in the dimensional,

functional and material reports are easily conducted.

For all vehicle components (non Powertrain – Powertrain skip to

section 1.3), the 2-D Drawing should include the Tolerance band,

Minimum, Maximum and Average Deviations from nominal and

Range.

Examples:

Figure 1: Manual

1.3 Design Record / 3D Math Data

The Design Record can include but are not limited to sketches,

marked prints, math data, blueprints, and other auxiliary drawings

(i.e. GD&T).The math data release shall be the same level as

that of the manufactured part , as per the Design Level Suffix

(DLS/PLS as well as the ST/REV/PDI).

In the event that math data is not available, suppliers shall

request the math data from GM Product Engineering for

construction of required part.

The Part Quality Warrant form shall log the number of the math data file used for the part manufacturing as well its release level and release date. 1.4 Material Certification

The material certification is a document from the material

producer that states the manufacturing location, lot number,

product identification number, product name, dates of test, and

test data required to show compliance to GM product

specifications. Material certification shall be on file at the supplier

location and available for review at GM’s discretion.

In case the supplier is not able to use the specified raw material,

and it is necessary to use an alternative corresponding material,

the supplier shall contact the GM Release Engineer and PPO

Process Engineer/Material Analyst for indication and approval for

the alternative material to be used for the manufacture of the

parts.

In the event the alternative material is used for the submitted Pre-

Production/Prototype part, the supplier shall complete a PPQP-2

Corrective Action Plan along with the completed raw material

certificate and submit both with the PPQP-1 Part Quality Warrant.

1.5 Key Characteristics

The General Motors Key Product Characteristics (KPC’s)

Designation System (KCDS)/GMW15049 sets forth the methods

and requirements for the identification and documentation of part

functional checks, product traceability and product characteristics

that are designated as Special Characteristics.

Parts and/or systems required to follow the KCDS (Key

Characteristics Designation System) process are selected based

on new unique design or technology, past history and current

items listed on KCDS templates. Suppliers are required to procure

GM Engineering Standards from the GM authorized distributor of

Engineering Standards. To procure and review the

KCDS/GMW15049 Engineering Standard for specific requirement

information, click on the following URL:

http://auto.ihs.com/collections/abstracts/gm-standards.html

page for GM Authorized Standards. To access the GMW15049

standard, enter GMW15049 in the search field in the “Standards

Store” “Search for Standards by Document Number, Title or Key

Words” field located on the mid-left side of the page.

Suppliers are responsible for performing, or having performed, the

inspection and/or tests required to substantiate conformance to

design record, coordinate measuring machine printout or facsimile

prior to the shipment of parts to the GM PPO Build Site. These

actual measurements must be cross-referenced to the design

record supplied by GM or the design record utilized to inspect the

part.

1.6 Dimensional Report

Suppliers are required to provide dimensional reports as

supporting documentation along with the PPQP-1 Part Quality

Warrant.

The submission of a dimensional report shall include the

information referenced in the example below.

Example: Required information by GM regardless of the

Dimensional Report format used:

2 Dimensional Measurements

2.1 Preparation

Parts may be controlled through the Coordinated Measuring

Machine (CMM) or through attributes using a certified control

device that considers the GD&T specifications.

2.2 Means of Control

In all cases the supplier is responsible to have a process control

plan.

2.2.1 Measurement using CMM or Scanning Technologies

When CMM or scanning technologies are specified, the

equipment shall meet all requirements as to calibration,

repeatability and reproducibility of the results.

2.2.2 Measurement by Attribute

In this process, the parts shall be submitted to attribute inspection

as to reference values resulting from previous inspection and

validation of a control fixture, based on GD&T concept. In this

case, the fixture dimensional report shall be submitted and the

parts control in the fixture shall depend on validation by PPO

Supplier Quality Engineering.

2.2.3 Free Form Holding Fixtures For all vehicle components

only (Powertrain suppliers skip to section 2.3.1)

Suppliers shall use a holding fixture that meets criteria specified in

Checking Fixture Standards and repeatability requirements for

repeatability (1 x 10). Fixture Datums must reflect GD&T callouts.

Free state requirements identified in GD&T must be followed (Ref.

GM1925 Fixture Standards).

Examples:

2.3 GD&T (Geometric Dimensioning and Tolerance)

2.3.1 Definition

GD&T is a procedure that integrates and standardizes the

interactions among quality, design and manufacturing process,

guaranteeing product dimensional, its manufacturing

specifications, and making sure full and functional

interchangeability of coupled parts through the application of

geometrical tolerances and admitting bonus in a few situations

and, consequently customizing the process and increasing its

capability.

For all vehicle components only, (not for Powertrain suppliers).

GD&T also includes feature control frames for Free State

checking requirements.

2.3.2 Application and responsibilities

Suppliers are charged the responsibility to “correctly apply the

GD&T concepts” and assuring any personnel directly

responsible for the development and validation phases of the

supplied products are fully updated and capable.

For dimensional requirements, refer to the GMW15745

GM Dimensional Management Supplier Minimum Standard.

GMW15745 Standard located via the following URL:

http://auto.ihs.com/collections/abstracts/gm-standards.htm

2.4 Measurement through 3D Comparison

2.4.1 Geometrical Elements Measurement and Qualification

When specified in drawings, the supplier shall perform

measurement of geometrical elements by observing the priorities

below:

Diameter, width, thickness and length, by observing the

shape regularity and element individual tolerance;

Application of GD&T tolerances and its modifiers (material

condition);

Calculation of true position, and other data based on

specifications detailed in 2D drawing.

http://auto.ihs.com/collections/abstracts/gm-standards.htm




2.4.2 Matching/Mating Surface Measurement

The matching area is understood as any surface area that has an

interface with any other part at assembly; this shall contain a

number of points to be controlled so as to assure conformance.

Example:

2.4.3 Trim Measurement

2.4.3 Trim Measurement

Trim measurement consists of measurements made in the

product end (edge), where the dimensional measurements shall

be carried as detailed in the example.

In continuous areas, spacing between measurement points may

be longer and in curvilinear areas (radius) spacing between

measurement points shall be smaller. Nevertheless, control shall

always be observed as to assure product conformance.

Example:

2.4.4 Surface Measurement

In more complex shapes, measurement between points shall be

less spaced and whenever possible they shall be taken in one

same section.

Examples:

2.4.5 Requirements for Part Mark-up (Vehicle Body and White critical parts only) (Powertrain suppliers – skip to section 3)

Note: For all points checked, only mark out-of-specification points on the part. Indicate the vehicle position and directional deviation from nominal of the checks that were out-of-specification, again using the following abbreviations: HI/LO, INB/OTB and FWD/AFT

Prerequisites to marking up a dimensional part:

Checking fixture has passed a Gage R study, 1X10, one operator, one part checked ten times.

Current GD&T and Checking Fixture Operating Procedure (OP).

Source has reviewed the requirements within this procedure.

Perform sight-checks for any holes, slots, cutouts, etc... If a hole is missing, a new part is required. Write on each part in black or yellow permanent marker or paint pen: part name, part number, engineering change level, run date, MRD, and the part’s identifying sequence number. Load and clamp the parts onto the checking fixture according to the OP/GD&T Instructions. Location, size and corresponding clamping sequence for all of the checking fixture datums should be drawn on the part in yellow/black. Also label each datums corresponding GD&T call-out in yellow/black.

Conduct a Free State Datum Check (FSDC). Use the part material thickness criteria specified within the Free State Datum Definitions document. Record the FSDC results onto the part in yellow/black utilizing the following note: FSDC______ mm. If the Free State Check fails, Integration Vehicle Build Team approval is required prior to part submission. Measure specified GD&T holes, slots, cutouts etc., for size in two directions, using calipers or other appropriate measuring device. All holes that are out-of-specification for size must be marked on the part in white permanent marker or paint pen. Denote the actual hole size measured and record to the nearest 0.1mm for each direction. Readings that are out-of-specification for variable surface (flush) measurements that were taken on the periphery of the part, per the checking routine, must be recorded on the part in red. Use a “dot with attached line” symbol to indicate where the exact measurements were out-of-specification on the part, see example (Attachment E2). Surface features not contained in the periphery check (example: surfaces on the interior of the part), must be evaluated against the checking fixture features, e.g. swing templates.

Readings that are out-of-specification for variable trim (gap) measurements that were taken on the periphery of the part, per the checking routine, must be recorded on the part in yellow. Use a “yellow arrow” symbol to indicate where the exact measurements were taken on the part. 2.5 Assembly Joining Quality Verification

All assembly joining methods shall be verified in accordance

to the following requirements within this section. The

supplier shall provide quality reports to GM Supplier Quality

for each joining method used based upon the applicable

GMW standard. The supplier may request for GM approval

any exception or deviation to the standard and/or Sampling

Plan during the Program Check Strategy Review with GM

Product Engineering.

3. Inspection Requirement

3.1 Sampling Plan

Samples shall be arranged to assure conformance to both

handling and control, thus avoiding the parts to be furnished

present any rust points, injection points, cracks, distortions, burrs,

misshaped areas etc.

Unless otherwise specified by GM, the minimum amount of parts

to be submitted to full inspection is as follows:





Supplier to provide 10 CONFORMING CMM checked parts.

Supplier required to check the first 3 parts per DES file provided.

Remaining 7 checks will be used at discretion of SQE/VDQM/DRE.

Parts must meet the minimum regional dimensional Requirements:

- (GMNA-PPO Vehicle only – 85%)

- (SGM – PPO Vehicle only – 80%)

- (GMK – PPO Vehicle only – 85%)

- (GMB – PPO Vehicle only – 85%)

Supplier is responsible to have Quality Process Control Plan in place to maintain minimum dimensional, functional and quality requirements.

Exceptions to this sampling plan may be required if determined by

GM at the checking strategy approval meeting.

The supplier should review the inspection data on the required

parts to determine part to part variations are within an acceptable

range and that no parts will be statistically out of print tolerance

based on the batch size of the order.

In case of any discontinuous variation that is likely to jeopardize

the capability of assembling and/or functionality, then the whole

batch shall be inspected 100% until process is deemed in control.

Remark: Whenever Key Characteristics are indicated in a

drawing these features shall be inspected for all parts (100%)

(Refer to item 1.5)

For parts that are delivered to GM as a final assembly, (ie parts

delivered from a Tier 2 to a Tier 1) the Tier 1 supplier is required

to retain inspection documentations for the sub-components and

any pertinent documentation for the assembly processes (staking

load, press-in load, etc.) that form the final assembled part. This

information will be made available to GM upon request. Tier 1

suppliers are responsible to ensure that all of their tiered

suppliers perform inspection in accordance to the inspection

requirements. Tiered suppliers will serialize parts so that the

inspection data can be correlated.

The dimensional measurements shall be representative and the

supplier shall have an internal process control plan to assure that

the item in the different process steps are in control, by collecting

samples at random.

GM reserves the right to audit the Supplier’s process control at

any time.

3.2.1 PPQP Parts procured with a M Suffix (Measured)

GM will require certain suppliers to fully inspected parts

using an “M” suffix as a PLS. This will be specified on the

purchase order, when required. M suffix parts shall require

the supplier to bubble the print for each dimension and

record the feature, tolerance and measurement in a

spreadsheet of other approved document. The inspection

documentation shall be sent to GM regardless of the

conformance to the design record.

Design Responsible Suppliers - Suppliers who own the

design responsibility will certify that the parts have been

100% inspected.

The design responsible supplier shall provide GM with the

interface dimensions, and the supplier design measurements

will be retained by the supplier.

3.3 Serialization

The serialization shall be engraved in all parts to assure proper

tracking using the example shown:

Identify parts by linking the part number and DLS, PLS according

to the Bill of Materials. The combination is given with the

Purchase Order.

This marking shall be indelible (i.e., using electrical pen, type,

industrial marker etc.), and shall not compromise the item

conformance, i.e., it shall not cause any distortions to samples nor

compromising the part function nor appearance. Contact the GM

representative to evaluate alternatives when the serialization

process will compromise part quality or performance.

Tiered suppliers shall also serialize their subcomponent parts so that inspection data can be correlated.

The serial number is continued only as long as the design level is

maintained. If production of a new design level of a specific part

number has started, the serial numbers start again with ‘0001.’

Note: Reworked parts require a new serial number.




The serial number is to be configured as follows:

Example: S-0001, S-0002, S-0003.

3.4 Part Identification & Container Labels

3.4.1 PPQP Part Identification and Traceability

Suppliers must utilize the PPQP-3 Pre-Production Part Tag for all

Pre-Production/Prototype parts.

3.4.2 PPQP Part Identification for fully inspected parts (M Suffix)

The M suffix will allow the part to be stored separately and

identified for engineering review as it is received in the

warehouse. The parts should be tagged, serialized (if

possible, checking with DRE for approved location) and

individually packaged (if possible). The supplier should use

the part number(s) ordered on the PO.

Example: 90578945 D M

PLS

PPQP-3 Pre-Production Part Tag

3.4.3 Shipping Container Label

All containers must be identified with the PPQP-4 Pre-Production

Container Label. The container shall assure that parts will be duly

arranged, thus preventing any distortion or damage during

transportation. The Container label shall be fixed outside the

container in an easily visible location.

PPQP-4 Pre-Production Container Label

3.5 Shipping & Containerization Requirements

Supplier is responsible for packaging and containing Pre-

Production material in a manner that will prevent

part/component damage during shipment. Pre-Production

packaging standards are available on GM Supply Power.
