APQP Sector Specific Guidance Petition

Experience has shown that variation in the interpretation of APQP, Control Plans (CP), and PPAP in non-traditional parts manufacturing sectors causes significant waste throughout the supply chain. Suppliers get different interpretations of what is expected from customers, supplier quality engineers, auditors, and internally between departments.


To improve the applicability of APQP/CP/PPAP by clarifying requirements for specific sectors or commodities with significant differences in design and manufacturing operations. Provide a means for developing, documenting, and distributing clarifications. Clarifications may include changes in terminology, alternate requirements, or change in applicability.

Rules for successful sector requirements:

  • Sector clearly defined.
  • Broadly applicable across the sector and possibly beyond that.
  • Sector consensus on agreement to use the revised definitions.
  • OEM agreement, as applicable.


Sector proposes clarifications indexed to the APQP/CP/PPAP requirements through the following process:

  1. The sector identifies and justifies the need for clarification (typically initiated by a few motivated representatives).
  2. The sector, to proceed with development of the guidance table, completes and submits a petition to AIAG using the on-line petition form.
  3. AIAG reviews the petition and works with the author to prepare it for submission.
  4. When all requirements are met, AIAG manages the review and approval process with the appropriate oversite team for the approval to start.
  5. AIAG, or the appropriate sector association, conducts a call to action for volunteers and forms a team to draft the guidance table.
  6. The sector team reaches consensus on the significant clauses in the APQP/CP/PPAP and develops the guidance table.
  7. The sector team submits the draft guidance table to AIAG for review with the appropriate oversite team for disposition.
  8. If rejected, AIAG provides feedback to the sector team.
  9. If approved, return to sector team for stakeholder review and reconciliation of comments.
  10. After final approval, AIAG announces and posts the guidance table as a free download.
  11. Ongoing edits and periodic reviews are managed by AIAG.

APQP Output Reference Alternative(s) Links to details/information to support alternative text
2.1 Design Failure Mode and Effects Analysis (DFMEA) DFMEA may follow the PFMEA 2.1 Design is generally dependent on the process. Therefore, the DFMEA may follow the PFMEA.
2.3 Design Verification Catalog items without a Customer specified set of requirements may have a generic verification. 2.3
2.12 Gages/Testing Equipment Requirements See 3.7  
3.5 Process Failure Mode and Effects Analysis (PFMEA) The PFMEA may precede the DFMEA 2.1
3.6 Pre-Launch Control Plan (including Error-Proofing Devices) Highly automated systems may not have a hardcopy control plan detailing every test. The control plan may refer to the automated controls and general requirements for reaction plans. https://www.iatfglobaloversight.org/wp/wp-content/uploads/2022/05/IATF-16949-SIs-May-2022.pdf

number 24
4.1 Significant Production Run Evidence of runs of similar products on the same equipment is sufficient.  
4.3 Preliminary Process Capability Study 100% automated inspection. Evidence of runs of products with equivalent tolerances on the same equipment is sufficient.  
4.4 Production Part Approval Default is Level 1  
4.7 Production Control Plan See 3.7  

Detailed explanations of the differences and instructions to address the APQP requirements:

  • 2.1 - Design is generally dependent on the process. Therefore, the DFMEA may follow the PFMEA.
  • 3.7 - See https://www.iatfglobaloversight.org/wp/wp-content/uploads/2022/05/IATF-16949-SIs-May-2022.pdf number 24

Final guidance must provide detailed explanations of the differences and instructions on how to address the APQP requirements
