ISO 9001:2026 Transition Plan: A 20-Week Template for Certified Companies
ISO Cloud Consulting editorial team
A company already certified to ISO 9001:2015 can plan its transition to ISO 9001:2026 over about 20 weeks of part-time work, in eight phases: understand, assess, plan, update, train, audit, review and certify. The plan below shows what to do each week and what evidence to keep.

Phase by phase
1. Understand (week 1)
Buy the standard. Read the requirements and Annex A. Brief top management for thirty minutes using a summary of the changes. Ask your certification body for its transition dates.
2. Assess (weeks 2 and 3)
Run the gap analysis with each process owner. Record evidence for what conforms and describe each gap.
3. Plan (week 3)
Convert gaps to tasks with owners and dates. Have top management approve the plan. Record it in your change log with its communication, monitoring and review arrangements.
4. Update (weeks 4 to 12)
- Weeks 4 and 5: context review, climate change relevance, interested parties.
- Weeks 6 and 7: quality culture and ethical behavior statement, leadership log, speak-up route.
- Weeks 8 and 9: split risks and opportunities, add disruption scenarios.
- Week 10: extend the change management procedure and form.
- Week 11: organizational knowledge and customer communication about disruption.
- Week 12: update clause references, policy wording, manual if you keep one, and the audit program.
5. Train (weeks 13 and 14)
Deliver a 45-minute awareness session to all staff and a short leadership module to top management. Brief internal auditors on the changes. Keep attendance and quiz records.
6. Audit (weeks 15 and 16)
Audit the changed requirements and sample the rest. See the internal audit questions for the new edition.
7. Review (weeks 17 and 18)
Hold a management review that covers transition status, audit results, risks, opportunities, changes and culture.
8. Certify (weeks 19 and 20)
Close actions. Send your certification body the evidence it asks for and confirm the transition audit.
