ISO 9001:2026 Transition Audit: How to Prepare

An ISO 9001 transition audit will be an important step for organisations moving from ISO 9001:2015 to the 2026 edition. ISO/FDIS 9001 has been approved, and ISO/TC 176 has announced that the sixth edition is scheduled for publication on 16 September 2026.

For organisations already certified to ISO 9001:2015, the transition is an opportunity to review the effectiveness of their Quality Management System (QMS), identify gaps and make necessary improvements. ISO has confirmed that organisations certified to ISO 9001:2015 will receive a transition period to migrate to the new edition.

However, preparing for a transition assessment is more than updating documents. Businesses need to demonstrate that relevant changes have been understood, implemented and integrated into their QMS.

This guide explains what an ISO 9001 transition audit involves, what organisations should prepare and what evidence auditors may need to review.

What Is an ISO 9001 Transition Audit?

An ISO 9001 transition audit is an assessment used to determine whether an organisation’s existing Quality Management System has been updated to meet the requirements of a revised edition of the standard.

The organisation does not normally need to build an entirely new QMS. Instead, it should:

• Review the new requirements
• Compare them with the existing QMS
• Identify applicable gaps
• Update processes where necessary
• Implement changes
• Train relevant employees
• Conduct internal audits
• Review the effectiveness of the changes
• Prepare objective evidence for the certification assessment

The exact transition assessment arrangements should be confirmed with the organisation’s certification body and the applicable accreditation requirements.

When Will the ISO 9001:2026 Transition Begin?

ISO’s current information lists ISO 9001:2026 as Edition 6, with publication scheduled for September 2026. ISO/TC 176 has specifically announced 16 September 2026 as the scheduled publication date.

ISO also states that organisations certified to ISO 9001:2015 will have a transition period to migrate to the revised edition.

This means certified organisations should plan ahead rather than waiting until the end of the transition period.

Important: The final transition deadline and detailed assessment arrangements should be confirmed through the applicable accreditation and certification-body arrangements. Businesses should avoid relying on unofficial deadlines published online.

ISO 9001 Transition Audit vs Regular ISO 9001 Audit

What Will an ISO 9001 Transition Audit Review?

An auditor will need objective evidence that the organisation’s QMS continues to meet the applicable requirements.

Depending on the organisation’s scope and the changes that affect its QMS, areas for review may include:

Leadership and Responsibility

Auditors may examine how top management demonstrates commitment to the QMS and how quality responsibilities are assigned.

Organisational Context

The organisation should understand its relevant internal and external issues and how these affect its ability to achieve intended QMS results.

Quality Objectives

Auditors may review whether quality objectives remain relevant, measurable where appropriate and aligned with the organisation’s direction.

Risks and Opportunities

Organisations should be able to demonstrate how relevant risks and opportunities are identified, assessed and addressed.

Quality Culture

ISO’s information about the 2026 edition highlights a stronger focus on leadership, quality culture and accountability.

Businesses should therefore be able to show that quality is integrated into how work is managed rather than treated only as a documentation activity.

Operational Processes

Auditors can review whether processes are effectively implemented and whether they produce the intended results.

Internal Audit

The organisation should be able to demonstrate that its internal audit programme is effective and that relevant findings are addressed.

Management Review

Management review records should demonstrate that leadership evaluates QMS performance and improvement opportunities.

Corrective Action

Where nonconformities or process problems have been identified, the organisation should be able to show how they were addressed and whether corrective actions were effective.

How to Prepare for an ISO 9001 Transition Audit?

1. Obtain the Final ISO 9001:2026 Standard

Start with the official published standard once it is available.

ISO currently lists the 2026 edition as under publication.

Avoid basing the final transition assessment solely on:

• Social media posts
• Consultant summaries
• Unofficial checklists
• Draft versions
• Blog articles

These resources can help with awareness, but the official standard should be the reference point for compliance.

2. Conduct a Gap Assessment

Compare your existing QMS with the final ISO 9001:2026 requirements.

A useful gap assessment can include:

The purpose is not to create unnecessary paperwork.

Instead, identify actual changes that affect your QMS.

3. Review Your Existing QMS

Before making changes, understand what already works.

Review:

• QMS scope
• Quality policy
• Quality objectives
• Process maps
• Procedures
• Work instructions
• Risk assessments
• Supplier controls
• Customer feedback
• Performance indicators
• Internal audits
• Management reviews
• Corrective actions

A mature QMS may already address many of the requirements that are relevant to the revised edition.

4. Identify Changes That Actually Affect Your Organisation

Not every change will have the same impact on every organisation.

For example, a manufacturing company, software company and healthcare organisation may have different processes and risks.

Consider:

What has changed?

↓

Does it apply to our organisation?

↓

Is our existing process already sufficient?

↓

If not, what needs to change?

This approach helps prevent organisations from unnecessarily rewriting their entire QMS.

5. Update Relevant Processes and Documents

After the gap assessment, update only what is necessary.

Potential updates may include:

• Policies
• Procedures
• Process documentation
• Risk assessments
• Quality objectives
• Responsibilities
• Monitoring methods
• Internal audit criteria
• Management review inputs

Remember that document changes alone do not demonstrate implementation.

Employees must understand and follow the updated processes.

6. Train Relevant Employees

Training should be based on the person’s role.

For example:

Top management

→ Leadership and quality responsibilities

Quality team

→ Revised requirements and audit preparation

Process owners

→ Changes affecting their processes

Employees

→ Changes affecting their daily activities

Keep evidence of relevant training and awareness activities where appropriate.

7. Conduct an Internal Audit

Before the external transition assessment, conduct an internal audit against the applicable ISO 9001:2026 requirements.

The internal audit should ask:

• Have applicable requirements been addressed?
• Have process changes been implemented?
• Do employees understand the changes?
• Is objective evidence available?
• Are processes producing intended results?
• Have identified gaps been addressed?

This gives management an opportunity to correct issues before the certification assessment.

8. Complete Management Review

Management should review the QMS and the results of transition preparation.

Relevant information may include:

• Internal audit results
• Customer feedback
• Process performance
• Quality objectives
• Risks and opportunities
• Corrective actions
• Resource needs
• Improvement opportunities

The review should demonstrate active management involvement.

9. Prepare Objective Evidence

One of the most important parts of audit preparation is evidence.

Examples may include:

• Approved policies
• Updated procedures
• Risk assessments
• Quality objectives
• Training records
• Internal audit reports
• Management review records
• Customer feedback
• Corrective-action records
• Process performance data
• Improvement records

The exact evidence required will depend on the organisation’s scope, processes and applicable requirements.

10. Coordinate With Your Certification Body

Do not wait until the last moment to contact your certification body.

Discuss:

• Transition arrangements
• Audit timing
• Audit scope
• Required evidence
• Applicable transition requirements
• Whether the transition assessment is integrated with another scheduled audit

The International Accreditation Forum’s general transition procedure recognises planning, impact analysis, implementation and transition assessment as important parts of moving between versions of normative documents.

The specific arrangements for ISO 9001:2026 should, however, be followed once the applicable transition requirements are formally established.

What Documents Should Be Ready for the Transition Audit?

There is no universal document list that applies identically to every organisation.

However, organisations should consider having relevant evidence available for:

QMS Documentation

• QMS scope
• Quality policy
• Relevant procedures
• Process information

Risk and Planning Information

• Risks and opportunities
• Quality objectives
• Action plans

Operational Evidence

• Process records
• Monitoring results
• Customer feedback
• Supplier evaluations

Audit Evidence

• Internal audit programme
• Internal audit reports
• Corrective actions

Management Evidence

• Management review records
• Decisions
• Resource requirements
• Improvement actions

The evidence should reflect the organisation’s actual operations.

Common ISO 9001 Transition Audit Mistakes

Updating Documents Without Implementing Changes

A revised procedure is not enough if employees continue following the old process.

Starting Too Late

Waiting until the end of the transition period can create unnecessary pressure.

Ignoring Quality Culture

The 2026 edition places greater emphasis on leadership, quality culture and accountability.

Treating the Audit as a Documentation Exercise

Auditors look at how the QMS operates, not just what documents exist.

Not Reviewing Internal Audit Results

Internal audits should help identify weaknesses before the external assessment.

Using Draft Information as the Final Requirement

The formal assessment should be based on the final published ISO 9001:2026 edition.

What Happens After the ISO 9001 Transition Audit?

The outcome will depend on the assessment and applicable certification procedures.

If the organisation demonstrates conformity with the applicable requirements, the certification body can proceed according to its certification decision process.

If nonconformities are identified, the organisation may need to:

1. Understand the finding.
2. Identify the cause where required.
3. Implement corrective action.
4. Provide appropriate evidence.
5. Undergo any required follow-up assessment.
6. Complete the certification body’s decision process.

Organisations should work directly with their certification body regarding specific timelines and requirements.

Does the Transition Audit Mean You Need a New QMS?

No.

ISO’s information describes ISO 9001:2026 as building on the established ISO 9001 framework, with targeted updates intended to improve clarity, usability and relevance.

Therefore, organisations should not automatically replace every existing procedure.

A better approach is:

Review → Gap Assess → Update → Implement → Audit → Improve

This keeps the transition practical and focused on the effectiveness of the QMS.

How Can Small Businesses Prepare for the Transition Audit?

Small businesses can use a simple, structured approach.

Start with the current QMS

Do not create a second management system just for the transition.

Identify actual gaps

Focus on requirements that affect your organisation.

Assign responsibilities

Give each action an owner and target date.

Keep evidence simple

Use existing business records wherever they demonstrate conformity effectively.

Conduct an internal audit

Use it to identify weaknesses before the external assessment.

Involve management

Top management should understand the changes and support implementation.

Conclusion

The ISO 9001 transition audit should be treated as an opportunity to strengthen the effectiveness of your Quality Management System rather than simply as a certification deadline.

ISO 9001:2026 is scheduled for publication on 16 September 2026, and ISO has confirmed that organisations certified to ISO 9001:2015 will have a transition period to move to the revised edition.

Organisations can prepare by reviewing the final requirements, conducting a gap assessment, updating applicable processes, training employees, completing an internal audit and preparing objective evidence.

Most importantly, the QMS should reflect how the organisation actually operates.

A practical transition approach is:

Understand → Assess → Update → Implement → Audit → Improve.
