ISO 9001:2015 vs ISO 9001:2026: main differences and what to review
Compare ISO 9001:2015 and 2026: leadership, risks and opportunities, change planning, knowledge and improvement, with practical audit examples.
ISO 9001:2026 builds on the quality management system you already use. The practical task is to identify where revised requirements affect your decisions, controls and evidence, then make targeted changes. Replacing the year on your procedures will not establish conformity.
ISO published the new edition on 16 September 2026. Its official publication page confirms its status. This overview responds to the topics in Carlos Pereira da Cruz’s Advisera comparison, with the headline changes checked against ISO’s own explanations.
ISO 9001:2015 vs 2026: the main differences
The process approach, customer focus, risk-based thinking and continual improvement remain. ISO describes a focused revision rather than a replacement management model. The table summarises the main review areas; it does not reproduce the standard’s requirements.
| Area | 2015 baseline | 2026 emphasis |
|---|---|---|
| Leadership and awareness | Leadership commitment and employee awareness already mattered. | Quality culture and ethical behaviour become explicit leadership and awareness themes. |
| Risks and opportunities | Both were addressed within planning. | Actions for risks and opportunities are distinguished more clearly. |
| Planning changes | Changes to the QMS were already planned. | Change planning expands to cover communication, monitoring, evaluation and review. |
| Organisational knowledge | Necessary knowledge was maintained and made available. | More explicit attention to retaining, applying and sharing knowledge for QMS results. |
| Improvement | Improvement and corrective action were established expectations. | Continual-improvement provisions are consolidated and clarified; improvement itself is not new. |
| Explanatory guidance | Users already had supporting explanations. | Expanded Annex A helps explain terminology and intent. |
| Climate considerations | Added through the 2024 amendment. | Carried into the new edition, rather than introduced for the first time. |

1. Make quality culture visible in decisions
ISO’s announcement emphasises leadership, quality culture and ethical behaviour. A useful review therefore looks beyond whether a policy has been signed.
Illustrative example: a production manager is under pressure to ship a batch before testing is complete. Examine who can stop release, how concerns are escalated and whether the decision is recorded honestly. A training attendance sheet alone will not explain how people respond under pressure.
Get-ISO review prompt: sample one recent quality concern and trace the response from the person who raised it to the management decision.
2. Give opportunities their own decisions
ISO’s publication summary distinguishes dealing with risks from pursuing opportunities. A list containing only potential failures can leave the second part underdeveloped.
Illustrative example: a fabricator identifies a risk of inaccurate measurements and an opportunity to introduce digital measurement capture. The first needs a control decision; the second needs an assessment of benefit, resources and feasibility. Record who will act and how the result will be judged. These are practical recording suggestions, not prescribed forms.
3. Follow changes through to results
Advisera highlights stronger change planning and a broader treatment of organisational knowledge. Use these as areas for a detailed comparison with the published standard.
Illustrative example: when introducing new scheduling software, check more than installation. Identify affected customers and staff, transfer essential knowledge, trial the revised workflow and compare missed deliveries before and after the change. If the change causes new errors, assign a response rather than declaring completion at go-live.
Get-ISO review prompt: select one completed change and check whether its intended result was achieved and the learning reached the people who need it.
4. Review the supporting controls
The Advisera comparison also flags customer and supplier communications, internal-audit objectives and management-review inputs. These deserve attention in a transition gap assessment. Read the applicable clauses before deciding that a specific new record or procedure is required.
For a practical starting sample, follow one changed customer order through acceptance, supplier instructions, delivery and feedback. Check whether the internal audit and management review would detect a failure in that chain. Treat this as a suggested audit trail, not a complete transition checklist.
5. Separate existing obligations from new changes
Climate-change consideration predates the 2026 edition: ISO issued the 2024 amendment to ISO 9001:2015. Assessing the new edition should not obscure whether your business already addressed that amendment.
Check your reasoning about relevance to the QMS and any relevant customer requirements. The ISO/IAF Auditing Practices Group guidance explains that the amendment does not automatically require climate initiatives where climate change is not relevant to QMS results.
A practical transition review
- Confirm the basis. Obtain the published standard and your certification body’s written transition arrangements. Separate publication dates, certificate expiry and applicable transition dates.
- Compare processes. Match revised requirements to existing controls and evidence. Keep effective arrangements; record genuine gaps and accountable owners.
- Test implementation. Sample actual decisions, changes and operational records. Check understanding with staff, not just document revisions.
- Review readiness. Use internal audit and management review to assess remaining gaps, resources and effectiveness before the agreed certification audit.
Get-ISO provides independent ISO 9001 gap assessments. The appointed certification body controls certification audits, transition acceptance and certification decisions. A gap assessment does not issue a certificate or guarantee a result.
