ISO 9001:2015 vs ISO 9001:2026: Key Changes Explained for Quality Professionals

 ISO 9001:2015 vs ISO 9001:2026 – What Has Changed and What Does It Mean for Quality Professionals?

Quality management systems are not only about procedures, formats and audit checklists. A good QMS should help an organization understand customer requirements, control its processes, manage risks, make better decisions and continuously improve.

After several years with ISO 9001:2015, the new ISO 9001:2026 edition has now been published. ISO officially published the sixth edition on 16 September 2026, replacing ISO 9001:2015.

For organizations already working with ISO 9001:2015, the important point is that ISO 9001:2026 is not a completely new quality management system. It builds on the existing framework while strengthening and clarifying several areas that have become more important in today's business environment.

ISO 9001:2015 vs ISO 9001:2026 – At a Glance

 

Area	ISO 9001:2015	ISO 9001:2026	Practical Impact
Leadership & quality culture	Leadership and commitment are required from top management.	Stronger emphasis on leadership, quality culture, accountability and ethical behavior.	Auditors and organizations will need to look beyond the quality policy and consider how leadership demonstrates quality culture in practice.
Strategy & quality policy	Quality policy and QMS are linked to the organization's context and strategic direction.	The connection between quality management, business strategy and organizational objectives is made clearer.	Quality objectives and management review should demonstrate how the QMS supports business direction.
Risks & opportunities	Risk-based thinking is a key part of the QMS.	Clearer distinction between managing risks and pursuing opportunities.	Organizations should consider both prevention of undesirable results and actions that can create beneficial results.
People & awareness	People need appropriate awareness and competence for the QMS.	Greater emphasis on people's contribution to quality culture and ethical behavior.	Training and awareness should go beyond simply explaining procedures.
Climate change	The 2024 amendment added consideration of climate change to the context of the organization and relevant interested-party requirements.	The climate-change consideration introduced through the 2024 amendment is carried forward.	Organizations should continue to consider whether climate change is a relevant issue for their QMS.
Annex A	No equivalent explanatory Annex A in ISO 9001:2015.	New informative Annex A provides clarification on concepts, terminology and the intent of requirements.	Useful for internal auditors, quality managers and organizations interpreting requirements.
Digitalization & changing business environment	Technology and organizational changes are addressed through the existing QMS framework.	The revised edition reflects modern business conditions, digitalization, complex supply chains and resilience more clearly.	Organizations should consider whether their existing processes and controls remain suitable for today's operating environment.
Continual improvement	Organizations are required to improve the suitability, adequacy and effectiveness of the QMS.	The revised edition continues the improvement approach while strengthening the connection between quality management, performance and organizational decision-making.	KPI trends, management review and improvement actions should demonstrate that information is being used to improve the QMS.

 

ISO states that the 2026 edition retains the familiar Harmonized Structure and continues to be based on established principles such as customer focus, the process approach, risk-based thinking and continual improvement.

 

1. Leadership: From Commitment to Quality Culture

Leadership has always been an important part of ISO 9001.

Under ISO 9001:2015, top management is expected to demonstrate leadership and commitment to the QMS.

ISO 9001:2026 puts greater emphasis on quality culture, accountability and ethical behaviour. ISO describes this as strengthening the role of leadership and creating an environment in which people actively contribute to the effectiveness of the QMS. 

This means that a quality policy displayed on a wall is not enough by itself.

For example, in a fabrication organization, leadership can demonstrate quality culture by:

·                Giving adequate time for inspection.

·                Supporting proper material traceability.

·                Ensuring qualified personnel are available.

·                Not allowing production pressure to bypass required inspections.

·                Supporting corrective and preventive actions.

·                Providing appropriate training.

·                Acting when repeated quality problems are identified.

In simple words:

Quality culture should be visible in actions, not only in documents.

 

2. Risks and Opportunities

Risk-based thinking was already a major part of ISO 9001:2015.

ISO 9001:2026 provides greater clarity in distinguishing risks from opportunities. ISO describes this as encouraging organizations to proactively manage risks while also pursuing opportunities that can produce beneficial results.

Consider a fabrication project.

Risk

Incorrect material identification could result in the wrong material being fabricated.

Possible action:

Improve material identification and traceability controls.

Opportunity

The organization identifies that digital inspection records could reduce manual errors and improve retrieval of quality records.

Possible action:

Introduce a controlled digital inspection-record system.

Both should be considered, but they are not the same thing.

A risk focuses on preventing or reducing undesirable results.

An opportunity focuses on achieving a beneficial result.

 

3. Greater Focus on People

Quality is ultimately achieved through people and processes.

ISO 9001:2026 gives greater attention to people's understanding of quality culture and ethical behavior.

For a manufacturing or fabrication organization, this could mean paying closer attention to whether employees understand:

·                Why is a particular inspection required.

·                Why material traceability is important.

·                Why should NCR not be hidden.

·                Why a WPS must be followed.

·                Why do inspection records need accurate actual values.

·                Why quality cannot be compromised simply by meeting a production target.

A trained person should not only know what to do but also understand why it matters.

 

4. Climate Change and the QMS

Climate change was introduced into the ISO 9001 context through the 2024 amendment.

The 2026 edition carries this consideration forward. ISO confirms that organizations should continue considering climate change as part of their organizational context and relevant requirements where applicable.

For example, depending on the organization and its activities, relevant considerations could include:

·                Extreme weather affecting operations.

·                Temperature and humidity affect painting activities.

·                Supply-chain interruptions.

·                Water availability.

·                Energy-related considerations.

·                Customer or regulatory requirements related to climate change.

An important point is that an organization should determine whether climate change is relevant to its QMS context, rather than simply adding a generic statement to a procedure.

 

5. New Annex A

One notable addition in ISO 9001:2026 is Annex A.

ISO describes the new Annex A as informative guidance intended to clarify key concepts, terminology and the intent behind requirements. It does not create additional requirements.

This can be particularly useful for:

·                Internal auditors

·                Lead auditors

·                Quality managers

·                QMS coordinators

·                Management representatives

·                Training programs

It can help organizations interpret the requirements more consistently.

 

6. Technology and Modern QMS

Organizations today use technologies such as:

·                Cloud-based systems

·                Digital inspection records

·                Automated monitoring

·                IoT devices

·                Data analytics

·                Electronic document control

·                AI-based tools

ISO 9001:2026 reflects the changing business environment and the increasing role of digitalization.

However, the important lesson is not simple:

"We use digital technology, therefore our QMS is compliant."

The organization still needs to ensure that information used for quality decisions is reliable and appropriately controlled.

For example, if inspection records are digital, the organization should consider:

·                Data accuracy

·                Access control

·                Revision control

·                Backup

·                Record retention

·                Traceability

·                Validation of relevant systems

Technology should support the QMS rather than create another uncontrolled process.

 

7. Continual Improvement

Continual improvement remains an important part of ISO 9001.

The practical question for a Quality Engineer is:

Are we actually using quality data to improve the process?

For example, suppose a fabrication company records the following monthly NCR trend:

 

Month	Welding NCRs
January	18
February	15
March	12
April	9
May	7

 

The numbers are useful, but the Quality Team should ask:

·                What caused the reduction?

·                Which corrective actions worked?

·                Which defects remain?

·                Are the same defects appearing in another project?

·                What preventive action can be taken?

This turns quality data into a management tool rather than simply a record.

 

8. What Does This Mean for an Existing ISO 9001:2015 QMS?

An organization certified to ISO 9001:2015 does not need to throw away its entire QMS and start again.

ISO specifically states that organizations should build on their existing systems and processes, keeping what works and making targeted changes where necessary.

A practical transition approach could be:

Step 1 – Understand the changes

Review ISO 9001:2026 and identify the areas that affect your organization.

Step 2 – Conduct a Gap Analysis

Compare the existing QMS against the 2026 requirements.

Step 3 – Review Existing Processes

Check:

·                Context of the organization

·                Interested parties

·                Quality policy

·                Quality objectives

·                Risks and opportunities

·                Leadership involvement

·                Competence and awareness

·                Operational controls

·                Monitoring and measurement

·                Internal audit

·                Management review

·                Continual improvement

Step 4 – Update Documents Where Necessary

Do not revise documents simply because the edition has changed.

Update them where the new requirements or organizational needs actually require a change.

Step 5 – Train People

Quality managers, internal auditors, process owners and employees should understand the changes relevant to their responsibilities.

Step 6 – Verify Effectiveness

After implementing changes, check whether they are working.

A procedure that has been revised but is not followed on the shop floor has not created an effective improvement.

 

A Practical Example from Fabrication

Imagine a fabrication company that has repeated welding defects.

Under a traditional approach, the QC team may:

Find defect → Raise NCR → Repair weld → Close NCR

A stronger QMS approach asks:

Why did the defect happen?

Was it related to:

·                Fit-up?

·                WPS compliance?

·                Welder qualification?

·                Consumable storage?

·                Preheat?

·                Welding parameters?

·                Supervision?

·                Training?

·                Production pressure?

Then the organization can identify the root cause and monitor whether the corrective action reduced the defect trend.

This is where a quality management system becomes more than an audit requirement.

It has become a management tool for improving business.

 

ISO 9001:2015 vs 2026 – The Main Message

The biggest change is not that organizations suddenly have a completely different QMS.

The 2026 edition keeps the familiar ISO 9001 framework while strengthening areas such as:

Leadership → Quality Culture → Strategy → Risks & Opportunities → People → Improvement

ISO describes the revision as targeted updates intended to improve clarity, usability and relevance rather than a fundamental change to the established quality management approach.

For organizations already operating an effective ISO 9001:2015 system, the transition should therefore be viewed as an opportunity to ask:

Is our QMS only helping us pass audits, or is it helping us improve the way we work?

That is perhaps the most important question for every Quality Professional.

Final Thought

A quality management system should not live only on procedures, manuals and audit reports.

It should be visible in:

Leadership decisions → Employee behavior → Process control → Inspection → Data → Corrective action → Improvement.

The purpose of ISO 9001:2026 is to keep the QMS relevant to the way organizations operate today while maintaining the foundation that has made ISO 9001 widely used around the world.

Quality is not only a department.
Quality is the way an organization works.
