How do you move from ISO 9001:2015 to ISO 9001:2026?
Use a controlled change process: establish the final requirements, compare them with the working QMS, implement necessary changes, check effectiveness and complete the agreed certification route. Keep current quality controls operating throughout. Rewriting every document is not a substitute for changing a weak process.
The new edition was published on 16 September 2026. The committee’s published transition endpoint for existing certified organisations is 30 September 2029. Your certificate expiry, customer commitments and the issuer’s decision steps may require earlier action.
Use the transition guide for the wider context. The sequence below is an original practical method; it does not prescribe extra ISO clauses, fixed implementation durations or a particular software system.
Step one: establish the baseline and ownership
Obtain authorised access to the final standard. Confirm the QMS scope, covered locations and current certificate details. Identify the certification body and the accreditation arrangements behind the service. Ask when accredited transition assessment will be available for your scope.
Name an accountable sponsor, project coordinator and relevant process owners. Assign decisions about resources and conflicting priorities to people with authority to make them. A coordinator who can chase actions but cannot resolve blocked changes needs a clear escalation route.
Write a short outcome statement: the organisation intends to demonstrate conformity with the new edition and obtain the appropriate certification decision. This helps distinguish the actual goal from intermediate tasks such as training or policy approval.
Step two: assess real gaps
Compare the published requirements with current processes and evidence. Use a requirement matrix to avoid omissions, then sample actual work to challenge claims of conformity. Include links between departments, outsourced activities and locations where these influence results.
Record each gap precisely. For example, say that decisions about a changed supplier control lack an assigned owner and follow up, rather than that supplier management needs improvement. The precise statement makes action and acceptance criteria easier to define.
Distinguish uncertainty from confirmed nonconformity. If evidence is unavailable, investigate rather than automatically declaring the whole process deficient. Conversely, do not label a genuine requirement gap as an optional improvement to keep the project looking healthy.
Step three: design proportionate changes
Prioritise work by effect on conformity, customers and the ability to complete the transition reliably. Specify who will change the process, what resources are needed and how the result will be checked. Include dependencies on systems, suppliers or central functions.
Consider a repair business that relies on experienced technicians to recognise recurring faults. A proportionate change might make those observations visible in existing job review meetings and link agreed actions to verification. A large new database would be useful only if it solved an identified control problem.
Before approving a solution, ask the people who perform the task whether it can work under normal conditions. A process designed around exceptional staffing or constant managerial intervention is unlikely to remain effective.
Step four: implement and communicate together
Introduce changed working methods and relevant documented information at the same time. Remove superseded instructions from active use. Explain what changed, who decides what and how uncertainty should be raised.
Check competence in the context of the task. For a reviewer, this may involve evaluating a realistic customer request. For a manager, it may involve explaining how quality issues affect resource decisions. Attendance at a briefing shows exposure to information, not necessarily ability to apply it.
Use the transition checklist as a control prompt, adapting it to your scope and processes. Record implementation evidence as work happens so the team does not later reconstruct an artificial audit story.
Step five: evaluate effectiveness
Let the changed process operate sufficiently to produce meaningful evidence. The appropriate period depends on the process and its frequency; the sources reviewed do not prescribe a universal waiting interval for every transition.
Internal audit should examine the revised criteria and their operation within the QMS. Sample transactions, speak with relevant staff and test handovers. Evaluate actions against acceptance criteria rather than closing them because a new document exists.
Management review should support decisions on unresolved issues, resources and timing. If a critical action is ineffective, adjust the plan and tell the certification body where the assessment proposal may be affected. Concealing a known readiness problem usually creates a larger decision problem later.
Step six: complete assessment and confirm the result
Agree whether transition will be combined with surveillance, recertification or a separate assessment. Confirm criteria, scope, evidence requirements and the certification decision process. Do not infer an audit duration from accreditation body assessment estimates.
After the visit, respond to findings through the issuer’s arrangements and retain evidence of effective action. Confirm the resulting decision before changing public certification claims. Check the revised certificate’s scope, locations, edition, dates and accreditation information.
Fold successful controls into normal operation and close temporary project arrangements deliberately. The transition should leave the organisation with a stronger working QMS and accurate assurance information, rather than a permanent second system maintained only for audits.
