For almost a decade, IATF 16949:2016 has defined what a quality management system looks like in the automotive supply chain. That is about to change. In July 2026 the International Automotive Task Force (IATF) issued Stakeholder Communiqué SC-2026-005, confirming that a second edition of IATF 16949 is in development and setting out the five areas it will address.
The timing is not accidental. IATF 16949 sits on top of ISO 9001, and ISO 9001:2026 was published on 16 September 2026. The automotive standard has to be rebuilt on that new base, and the IATF has used the opportunity to tackle problems suppliers have complained about for years: complexity, inconsistent interpretation and the sheer weight of customer-specific requirements.
This Insight explains what the IATF has confirmed, what each priority area is likely to mean in practice, and what suppliers can sensibly do now while the detail is still being written.
The short version: IATF 16949:2016 remains the standard for certification until the second edition is published, which the IATF currently plans for mid-2027. The revision focuses on simplification, software quality, lower-tier supplier management, launch management and customer-specific requirements. The IATF has said the transition will end at the same time as the ISO 9001:2026 transition, which closes on 30 September 2029, so the window to move to the new edition will be noticeably shorter than the window for ISO 9001 itself.
What the IATF Has Confirmed
The communiqué describes the second edition, referred to internally as Revision 2, as driven by stakeholder feedback from across the industry (IATF Stakeholder Communiqué SC-2026-005). Working draft development and external feedback are scheduled for 2026, final validation, translation and supporting documents for 2027, and publication for mid-2027. The IATF is clear that these dates remain indicative and may move as the work progresses.
The most important single line concerns the transition. Rather than giving the second edition its own three-year window, the IATF has aligned the end of its transition with the end of the ISO 9001:2026 transition. If publication lands in mid-2027, suppliers can expect roughly two years to complete their move, and certification bodies will need time to train auditors before transition audits are widely available. The practical window is tighter still.
The Five Priority Areas
1. Simplification, clarity and efficiency
The IATF wants a standard that is easier to understand, implement and audit, with less variation in how requirements are interpreted and less duplication with ISO 9001. Anyone who has watched two auditors read the same clause in two different ways will welcome this. It is also a signal that some of the Sanctioned Interpretations and Frequently Asked Questions issued since 2016 are likely to be absorbed into the requirements themselves.
2. Software quality assurance
IATF 16949:2016 says relatively little about software. The second edition will strengthen the quality management approach for embedded software, applying existing quality principles across the software lifecycle. For suppliers of electronic control units and software-defined features, this brings the core quality system closer to the development disciplines already expected by customers, such as Automotive SPICE. The IATF has stressed that it wants to improve software quality without adding unnecessary complexity, so a parallel software rulebook is unlikely.
3. Tier N supply chain management
Many of the quality failures that reach vehicle manufacturers originate several tiers down the supply chain. The revision will promote a more consistent risk-based approach to managing lower-tier suppliers, better deployment of customer requirements down the chain and clearer communication between tiers. Suppliers who currently rely on certificates and annual questionnaires for sub-tier control should expect to show more active, risk-proportionate oversight.
4. Launch management
Product and process launches are among the highest-risk periods in the automotive lifecycle. The revision will place greater emphasis on a structured approach to new products, change management and industrialisation. That aligns closely with the new Clause 6.3 on planning of changes in ISO 9001:2026, and it puts the quality of APQP, FMEA and control planning firmly in the spotlight. Organisations whose launch process exists mainly to satisfy PPAP submissions will find this area demanding.
5. Customer-specific requirements
Customer-specific requirements (CSRs) are consistently identified as one of the biggest burdens in the scheme. The IATF aims to improve how applicable CSRs are identified and managed, and to identify common CSRs that could be incorporated into the standard itself. If that succeeds, suppliers serving several vehicle manufacturers could see a meaningful reduction in the number of overlapping requirements they have to track.
What Stays the Same for Now
Until the second edition is published and the IATF issues its transition rules, nothing changes for certification. Audits continue against IATF 16949:2016, the IATF Rules for achieving and maintaining recognition (6th Edition, in force since 1 January 2025) and the current Sanctioned Interpretations, the most recent of which were issued in June 2026. Customer-specific requirements also continue to change independently, so keeping track of each customer’s current CSRs remains as important as ever.
It is also worth remembering that IATF 16949 certification works differently from ordinary ISO certification. Audits are carried out only by IATF-recognised certification bodies under IATF oversight, not under national accreditation such as UKAS. Transition arrangements will therefore come from the IATF and its oversight offices, and certification bodies will follow them closely.
What Automotive Suppliers Should Do Now
Start with the ISO 9001:2026 changes
The second edition will be built on ISO 9001:2026, so its changes will flow straight through. Quality culture and ethical behaviour from top management, risks and opportunities analysed separately, and a closed-loop approach to planning changes will all apply to automotive suppliers. These are published now, and they take time to evidence. Our overview of what has changed in ISO 9001:2026 explains each one.
Strengthen the areas the IATF has named
The five priorities tell suppliers where scrutiny will increase. Reviewing launch management, sub-tier supplier control, software quality and CSR management against current practice is useful whatever the final wording turns out to be. Improvements made now will deliver operational benefits immediately and reduce the work needed when the standard arrives.
Plan for a compressed transition
Check where your recertification and surveillance audits fall between mid-2027 and September 2029. With a shorter window, many suppliers will have only one or two realistic opportunities to transition. Organisations holding both ISO 9001 and IATF 16949 certification, or supplying other sectors as well, should plan one joined-up transition rather than separate projects. Our ISO 9001:2026 transition plan sets out a phased approach that works equally well as the foundation for IATF.
Avoid premature rewrites
Rewriting the quality manual against draft text that may change is wasted effort. Focus on behaviours and processes now, and leave the document changes until the published standard is in hand.
How Hillscom Helps
Our roots are in tier-one automotive supply, where TQM, problem solving and launch discipline were part of daily life long before IATF 16949 existed. We support suppliers with independent gap analysis and certification readiness reviews against the current standard and the published ISO 9001:2026 changes, practical improvement of launch management, FMEA and control planning, and joined-up transition planning across ISO 9001 and IATF 16949. Where a quality team is stretched by the transition, our interim management support can provide experienced leadership for as long as it is needed. You can read more about our IATF 16949 consultancy and our work in the automotive sector.
The Hillscom Perspective
The five priorities read like a list of lessons the industry has learned the hard way. Launches go wrong when change is poorly controlled. Field problems arrive from suppliers nobody was watching closely. Software defects escape processes designed for machined parts. None of these are new problems, and the suppliers who already manage them well will find the second edition far less disruptive than those who treat IATF 16949 as an audit to be passed. The best preparation is to run the business the way the revision describes, before anyone requires it.
Conclusion
IATF 16949 second edition is coming, with publication planned for mid-2027 and a transition that ends alongside ISO 9001:2026 in September 2029. The direction is clear even though the text is not yet final: a simpler standard with sharper focus on software, sub-tier suppliers, launches and customer-specific requirements. Suppliers who act on the ISO 9001:2026 changes and strengthen the named priority areas now will be ready when the detail arrives. We will update this Insight as the IATF publishes further information.
