IATF 16949 SIs and FAQs

The International Automotive Task Force (IATF) has approved the release of updated IATF 16949:2016 Sanctioned Interpretations (SIs) and Frequently Asked Questions (FAQs).

Sanctioned Interpretations alter the existing published requirements of the IATF 16949:2016 standard.  Frequently Asked Questions clarify an existing requirement.

Sanctioned Interpretations

The approved Sanctioned Interpretations include “revised” SI 8, clause, Supplier quality management system development and SI 10, clause, External laboratory.

The “new” Sanctioned Interpretations are shown below. The replaced text has strike-throughs and the new text is in bold.

SI 12 –  Clause, Process effectiveness and efficiency

Top management shall review the product realization processes effectiveness and efficiency of the quality management system  and support processes to evaluate and improve their effectiveness and efficiency the organization’s quality management system. The results of the process review activities shall be included as input to the management review (see Section

Rationale for change: Clarified that not every process requires an efficiency measure.  The organization needs to determine which processes require efficiency measures within their quality management system.  Additionally, the organization’s problem-solving processes need to have an effectiveness review conducted by the organization’s management.

SI 13 – Clause, Management review inputs – supplemental

Input to management review shall include:

a) cost of poor quality (cost of internal and external nonconformance);
b) measures of process effectiveness;
c) measures of process efficiency for product realization processes, as applicable;
d) product conformance;
e) assessments of manufacturing feasibility made for changes to existing operations and for new facilities or new product (see;
f) customer satisfaction (see ISO 9001, Section 9.1.2);
g) review of performance against maintenance objectives;
h) warranty performance (where applicable); i) review of customer scorecards (where applicable);
j) identification of potential field failures identified through risk analysis (such as FMEA);
k) actual field failures and their impact on safety or the environment.

Rationale for change: Clarified that not every process requires an efficiency measure.  The organization needs to determine which processes require efficiency measures within their quality management system.

Frequently Asked Questions

The approved Frequently Asked Questions include these two new entries:

FAQ 21 – clause 8.6.2, Layout inspection and functional testing

QUESTION:  Is a layout inspection different from a product requalification or functional testing?

ANSWER:  Yes, as stated in Note 1 of 8.6.2 of IATF 16949, [Layout inspection is the complete measurement of all product dimensions shown on the design record(s)]; layout inspection is limited to dimensional measurement and requirements. Performance or materials measurements are not included in a layout inspection.

Product requalification would normally imply full validation to all product approval requirements (e.g., PPAP or PPA) and therefore exceeds the scope of a layout inspection.

Functional testing/verification would normally be limited to performance and material measurements such as durability or tensile strength and would not include dimensional measurements.

Where frequency is not defined by the customer, the organization is responsible to define the frequency of layout inspection.

Layout inspection is a part of product requalification, if product requalification is required by the customer. On-going layout inspection and functional testing requirements are defined in the control plan.  If customer-specific requirements exist, then those requirements (including layout inspection and functional testing requirements) are also included in the control plan.

FAQ 22 – clause, Product audit 

QUESTION:  How does a product audit differ from a layout inspection?

ANSWER:  As defined in section 3 of IATF 16949, the term product is used to represent “…any intended output…” of the manufacturing process.

Products typically have dimensional, performance (functional) and material requirements, therefore, product audits may contain verification of dimensional, performance (functional), or material requirements. As stated in the FAQ 21 above, a layout inspection is limited to dimensional requirements.

Product audits can be carried out on finished or partially finished product, following customer specified approaches (e.g., VDA 6.5 Product Audit), if applicable.  Product audits may include packaging and labeling requirements.

A product audit, like other audit types, is an independent verification of compliance to requirements. As such, the product audit has a defined frequency and scope specified within the audit program and is based on risk.
