ISO 9001:2026 Important Update

ISO 9001:2026 was published on 16 September 2026 as the sixth edition of ISO 9001. ISO identifies it as the current edition, replacing ISO 9001:2015.

The 2026 revision does not completely change the QMS framework. Organizations already using ISO 9001:2015 can build on their existing systems and make targeted changes where necessary.

ISO highlights greater emphasis on:

Leadership and accountability
Quality culture
Ethical behavior
Strategic alignment
Risks and opportunities
People and awareness
Clearer application of requirements
Alignment with other ISO management system standards
A new Annex A providing additional clarification

The 10-clause structure remains familiar, which makes the transition easier for organizations that already understand ISO 9001.

For a complete overview of ISO 9001:2026 changes, 2015 vs 2026 comparison and transition guidance, read our [ISO 9001:2026 Complete Guide].

What Are the 10 Clauses of ISO 9001:2026?

ISO 9001:2026 follows a 10-clause structure:

Clause	Title	Main Purpose
1	Scope	Defines the scope of the standard
2	Normative References	Identifies referenced standards
3	Terms and Definitions	Establishes common terminology
4	Context of the Organization	Understand the organization and QMS context
5	Leadership	Establish leadership, commitment and customer focus
6	Planning	Address risks, opportunities, objectives and changes
7	Support	Provide resources, competence, awareness and documented information
8	Operation	Plan and control operational processes
9	Performance Evaluation	Monitor, measure, audit and review QMS performance
10	Improvement	Manage nonconformity, corrective action and continual improvement

Clauses 1–3 provide the foundation and terminology, while Clauses 4–10 contain the main QMS requirements. The 2026 edition retains the familiar Harmonized Structure.

Clause 1: Scope

What is Clause 1?

Clause 1 defines the scope and purpose of ISO 9001.

ISO 9001:2026 provides requirements for organizations that need to:

Demonstrate their ability to consistently provide products and services that meet customer and applicable requirements
Enhance customer satisfaction
Establish, implement, maintain and continually improve a QMS

ISO 9001 can be applied to organizations of different sizes and sectors, including manufacturing, automotive, engineering, construction, healthcare, education, IT, logistics and services.

Practical Example

An automotive component manufacturer may use ISO 9001 for:

Manufacturing and supply of precision machined automotive components.

The scope should clearly represent the organization’s actual activities and QMS boundaries.

Typical Audit Evidence

An auditor may review:

QMS scope
Site information
Products and services
Process map
Customer requirements
Applicable statutory and regulatory requirements

Auditor Questions

What is the scope of your QMS?
Why has this scope been selected?
Which products and services are covered?
Which locations and processes are included?
Are there any requirements that are not applicable?

Common Mistake

A common mistake is defining a scope that does not accurately represent the organization’s actual activities.

Tip: Keep the scope clear, realistic and consistent with the processes actually controlled by the organization.

Clause 2: Normative References

What is Clause 2?

Clause 2 identifies normative references relevant to understanding and applying ISO 9001.

ISO 9001 works within the ISO 9000 family of quality management standards. ISO 9000 provides fundamentals and vocabulary, while ISO 9001 specifies QMS requirements.

Practical Example

When QMS personnel need to understand terminology such as:

Quality
Process
Nonconformity
Corrective action
Documented information

they should use the applicable terminology defined within the ISO quality management vocabulary.

Typical Audit Evidence

Access to relevant ISO standards
QMS terminology or glossary
Auditor and QMS team awareness of applicable references

Auditor Questions

Which standards are relevant to your QMS?
How do you ensure that QMS personnel understand applicable terminology?
Which standard provides the vocabulary used by your QMS?

Tip: Do not treat normative references as simply a documentation exercise. Consistent terminology helps different departments interpret QMS requirements in the same way.

Clause 3: Terms and Definitions

What is Clause 3?

Clause 3 establishes the terminology used in ISO 9001.

Correct interpretation of terms is important because QMS activities depend on common understanding.

Examples include:

Process
Requirement
Nonconformity
Corrective action
Documented information
Customer satisfaction
Monitoring
Measurement

Practical Example

Suppose the quality department records a recurring defect as a “corrective action,” but the actual activity only fixes the defective product.

The organization should understand the difference between:

Correction: Fixing the detected problem.

Corrective action: Taking action to eliminate the cause of a nonconformity and prevent recurrence.

Typical Audit Evidence

QMS terminology
Procedures using consistent definitions
Auditor competence records
Employee awareness where relevant

Auditor Questions

What is a nonconformity?
What is corrective action?
What is the difference between correction and corrective action?
How do you ensure employees understand relevant QMS terminology?

Clause 4: Context of the Organization

Clause 4 is one of the most important parts of the QMS because it establishes the environment in which the organization operates.

It requires the organization to understand its context, relevant interested parties, QMS scope and processes.

4.1 Understanding the Organization and Its Context

The organization should determine internal and external issues that can affect its ability to achieve the intended results of the QMS.

Examples include:

Internal Issues

Employee competence
Manufacturing capacity
Equipment capability
Organizational culture
Process performance
Financial resources
Technology
Infrastructure

External Issues

Customer expectations
Market conditions
Competition
Laws and regulations
Supply-chain conditions
Technology changes
Economic conditions
Industry developments

Practical Example

An automotive supplier may identify:

Issue: Increasing customer demand for shorter delivery lead time.

Impact: Existing production capacity may become insufficient.

QMS response: Capacity planning, overtime control, additional equipment, process improvement or supplier capacity development.

4.2 Interested Parties

The organization should identify relevant interested parties and their relevant requirements.

Examples:

Interested Party	Possible Requirement
Customer	Product quality and on-time delivery
Government	Statutory/regulatory compliance
Employees	Competence and safe working conditions
Supplier	Clear requirements and timely communication
Owners	Business performance
Certification body	Conformity to applicable standard

Audit Evidence

Interested-party register
Customer requirements
Regulatory requirements
Context analysis
Business review records
Process documentation

4.3 Scope of the QMS

The organization should determine the boundaries and applicability of the QMS.

The scope should consider:

Internal and external issues
Relevant interested-party requirements
Products and services
Organizational activities
Sites and processes

Auditor Questions

What is your QMS scope?
How was the scope determined?
Which processes are included?
How do interested parties influence the scope?

4.4 Quality Management System and Its Processes

The organization should establish, implement, maintain and continually improve the QMS and its processes.

A process approach should identify:

Input → Process → Output → Customer → Measurement → Improvement

Example

For a production process:

Raw material → Machining → Inspection → Finished component → Customer

Possible controls include:

Material verification
Machine settings
Work instructions
In-process inspection
Final inspection
Traceability
Nonconforming-product control

Typical Audit Evidence

Process map
SIPOC
Turtle diagrams
Process KPIs
Procedures
Work instructions
Process interaction map
Process risk assessment

Common Audit Finding

The organization has a process map, but actual processes do not operate as described.

Tip: Your process map should reflect what actually happens on the shop floor.

Clause 5: Leadership

Clause 5 establishes the role of top management in the QMS.

Quality should not be treated as the responsibility of only the Quality Manager.

ISO 9001:2026 gives greater emphasis to leadership, quality culture, accountability and ethical behavior.

5.1 Leadership and Commitment

Top management should demonstrate leadership and commitment to the QMS.

Practical evidence may include:

Review of quality performance
Customer complaint actions
Resource allocation
Quality objectives
Improvement projects
Risk and opportunity decisions
Management review
Employee involvement

Auditor Questions

How does top management demonstrate commitment to quality?
How does management know whether the QMS is effective?
What actions has management taken after reviewing quality performance?
How are quality issues communicated to employees?

Quality Culture

A strong quality culture means employees understand that quality is part of their daily work.

For example:

If an operator identifies a serious defect, the organization should encourage reporting and containment rather than hiding the issue to meet production targets.

A good quality culture encourages people to:

Report problems
Prevent defects
Follow processes
Escalate important issues
Learn from mistakes
Participate in improvement
Understand customer requirements

5.2 Quality Policy

The Quality Policy should provide direction for the QMS and support the organization’s strategic direction.

A good policy should not simply be displayed on a wall.

Employees should understand:

What the policy means
How it relates to their work
How quality objectives support it
How continual improvement is achieved

5.3 Organizational Roles, Responsibilities and Authorities

Responsibilities should be clearly defined.

Typical evidence includes:

Organization chart
Job descriptions
Responsibility matrix
Process ownership
Delegation of authority
Quality responsibilities

Common Mistake

Writing responsibilities in an organization chart without ensuring that employees actually understand and perform them.

Clause 6: Planning

Clause 6 connects the organization’s direction with QMS planning.

It includes:

Risks
Opportunities
Quality objectives
Planning to achieve objectives
Planning of changes

6.1 Risks and Opportunities

ISO 9001:2026 provides greater clarity around risks and opportunities. The organization should not focus only on preventing negative outcomes; it should also consider opportunities that could produce beneficial results.

Example – Risk

Risk: Single-source supplier may stop supplying a critical raw material.

Possible action: Develop an alternate supplier and establish contingency arrangements.

Example – Opportunity

Opportunity: Automated inspection could reduce inspection time and improve defect detection.

Possible action: Conduct feasibility testing and implement the solution if effective.

Typical Audit Evidence

Risk and opportunity register
Process risk assessment
Action plans
Business continuity plans
Supplier risk assessment
Monitoring records

6.2 Quality Objectives

Quality objectives should be measurable where appropriate and relevant to the QMS.

Examples:

Reduce customer complaints by 20%
Improve on-time delivery to 98%
Reduce internal rejection below 1%
Improve supplier PPM
Increase first-pass yield
Reduce warranty claims

Each objective should ideally have:

Target + Responsibility + Resources + Timeline + Monitoring method

6.3 Planning of Changes

Changes should be planned and controlled.

Examples:

New machine
New supplier
New product
Process change
Manpower change
New software
Layout change
New customer requirement

Typical Audit Evidence

Change request

Competency evaluation
On-the-job training
Training effectiveness

Auditor Questions

How do you determine competence requirements?
How do you identify training needs?
How do you evaluate training effectiveness?
What happens when an employee is not competent?

Awareness

Employees should understand relevant QMS information and their contribution to quality.

They should understand, as applicable:

Quality policy
Relevant objectives
Their contribution to QMS effectiveness
Consequences of nonconforming output
Relevant responsibilities

ISO 9001:2026 gives greater emphasis to awareness connected with quality culture and ethical behavior.

Documented Information

The organization should control documented information required by the QMS.

Typical controls include:

Document identification
Revision status
Approval
Distribution
Access
Retention
Disposal
Prevention of unintended use of obsolete documents

Audit Evidence

Master document list
Controlled procedures
Work instructions
Forms
Records
Revision history
Electronic document control system

Clause 8: Operation

Clause 8 is where the QMS is translated into actual product or service delivery.

For manufacturing organizations, this is usually one of the most important clauses during an audit.

It includes areas such as:

Operational planning and control
Customer requirements
Design and development where applicable
Control of externally provided processes, products and services
Production and service provision
Release of products and services
Control of nonconforming outputs

Operational Planning and Control

The organization should plan and control the processes required to provide conforming products and services.

Automotive Manufacturing Example

A typical controlled production process may include:

Customer requirement → Production planning → Material → Machine setup → Process control → Inspection → Final inspection → Release → Dispatch

Possible evidence:

Production plan
Control plan
Work instruction
Inspection standard
Process parameters
Inspection records
Traceability records

Customer Requirements

Before accepting an order, the organization should understand applicable requirements.

These may include:

Product specifications
Drawings
Delivery requirements
Quality requirements
Packaging requirements
Applicable legal/regulatory requirements
Special customer requirements

Auditor Questions

How do you review customer requirements?
Who approves order acceptance?
How are changed requirements communicated?
How do you ensure production uses the latest customer specification?

Design and Development

Where design and development is applicable, the organization should control the design and development process.

Typical evidence may include:

Design inputs
Design reviews
Design outputs
Verification
Validation
Design changes

If design and development is not performed by the organization, applicability should be determined and documented appropriately.

External Providers and Suppliers

Supplier controls may include:

Supplier selection
Supplier evaluation
Supplier approval
Supplier performance monitoring
Purchase requirements
Incoming inspection
Supplier corrective action
Supplier development

Supplier KPIs

Supplier PPM
On-time delivery

Control of Nonconforming Outputs

Nonconforming products should be identified and controlled to prevent unintended use or delivery.

Typical evidence:

NCR
Rejection tag
Segregation area
Rework records
Scrap records
Concession/approval where applicable
Reinspection results

Common Audit Finding

The organization has a rejection procedure, but rejected material is physically mixed with accepted material.

Tip: Audit the physical implementation, not only the procedure.

Clause 9: Performance Evaluation

Clause 9 determines whether the QMS is performing effectively.

It includes:

Monitoring
Measurement
Analysis
Evaluation
Customer satisfaction
Internal audit
Management review

Monitoring and Measurement

Organizations should determine what needs to be monitored and measured.

Useful QMS KPIs include:

Customer complaints
Customer PPM
Internal rejection
First-pass yield
On-time delivery
Supplier PPM
Cost of poor quality (COPQ)
Process capability
Corrective-action closure
Audit findings

Important Tip

Don’t collect KPIs only because the auditor may ask for them.

Use KPIs to make decisions.

A good KPI should answer:

What is happening, why is it happening, and what action should management take?

Customer Satisfaction

Customer satisfaction can be evaluated using information such as:

Customer complaints
Customer scorecards
Customer feedback
Returns
Warranty data
Delivery performance
Customer surveys
Repeat business

Internal Audit

Internal audits should determine whether the QMS:

Conforms to applicable requirements
Is effectively implemented
Is maintained
Achieves intended results

A good internal audit should go beyond checking whether documents exist.

Example

Instead of asking:

“Do you have a work instruction?”

Ask:

“Show me how this process is performed and demonstrate how you ensure the current work instruction is being followed.”

Then verify actual records and results.

Typical Internal Audit Evidence

Audit programme
Audit plan
Checklist

Clause 10 focuses on improving the suitability, adequacy and effectiveness of the QMS.

It includes:

Improvement opportunities
Nonconformity
Corrective action
Continual improvement

Nonconformity and Corrective Action

When a nonconformity occurs, the organization should:

React to the problem.
Control and correct it where applicable.
Deal with consequences.
Determine whether action is needed to eliminate the cause.
Implement appropriate corrective action.
Review whether the action was effective.
Update relevant QMS information where necessary.

Example

Problem: Customer received components with incorrect dimensions.

Immediate correction: Contain and inspect affected stock.

Root cause: Incorrect machine offset entered after setup change.

Corrective action: Introduce setup verification and independent parameter confirmation.

Effectiveness: Monitor subsequent production lots and confirm recurrence has been prevented.

ISO 9001:2026 Documents and Records – Practical List

The exact documented information required depends on the organization’s QMS, but organizations commonly maintain evidence such as:

QMS scope
Quality Policy
Quality objectives
Process information
Organizational roles and responsibilities
Context and interested-party information
Risk and opportunity information
Competence records
Training records
Calibration records
Supplier evaluation records
Customer requirement records
Production records
Inspection records
Traceability records
Product release records
Nonconformity records
Corrective-action records
Internal audit records
Management review records
KPI/performance records
Improvement records

Do not create documents simply because an auditor might expect a particular format.

The better approach is:

Document what is needed to control the process and retain evidence where it is necessary to demonstrate effective implementation.

ISO 9001:2026 PDCA Model

ISO 9001 can be understood using the Plan–Do–Check–Act (PDCA) cycle.

PLAN

Clauses 4, 5 and 6

Understand the organization, leadership direction, risks, opportunities and objectives.

DO

Clauses 7 and 8

Provide resources and operate controlled processes.

CHECK

Clause 9

Monitor, measure, audit and review performance.

ACT

Clause 10

Correct problems and continually improve.

This creates a continuous improvement loop:

Context → Planning → Support → Operation → Performance Evaluation → Improvement → Better Planning

The purpose is not merely to maintain certification. The purpose is to create a QMS that consistently produces effective results.

ISO 9001:2026 Transition for Existing ISO 9001:2015 Organizations

Organizations certified to ISO 9001:2015 do not need to discard their existing QMS and start again.

A practical transition approach is:

1. Obtain and understand ISO 9001:2026

Use the official standard as the primary source.

2. Conduct a gap analysis

Compare the current QMS with the 2026 requirements.

3. Identify necessary changes

Focus on areas such as:

Leadership
Quality culture
Strategic alignment
Risks and opportunities
Awareness
Documented information
Relevant QMS processes

4. Update the QMS

Change procedures, forms and records only where necessary.

5. Train employees

Explain what the changes mean for their actual jobs.

6. Conduct an internal audit

Verify implementation and effectiveness.

7. Review with top management

Review transition status, resources, risks, training and actions.

8. Coordinate with the certification body

Agree on the appropriate transition audit arrangements.

ISO/TC 176 transition guidance states that organizations already certified to ISO 9001:2015 have until 30 September 2029 to complete their transition. From 31 March 2028, new and initial accredited certifications may only be issued to ISO 9001:2026.

For the full transition timeline and 2015-vs-2026 discussion, see our ISO 9001:2026 Complete Guide.

ISO 9001:2015 vs ISO 9001:2026 – What Does This Mean for the Clauses?

The overall clause structure remains familiar.

Area	ISO 9001:2015	ISO 9001:2026
Clause structure	10-clause structure	10-clause structure retained
Customer focus	Core principle	Remains central
Process approach	Core approach	Remains central
Leadership	Required	Greater emphasis
Quality culture	Less explicit	Greater visibility
Risks and opportunities	Risk-based thinking	Greater clarity
Strategic alignment	Addressed through QMS planning	Stronger emphasis
People awareness	Required	Greater emphasis on culture and ethical behaviour
Annex A	Previous structure	New clarification-oriented Annex A
Climate change	Added through 2024 amendment	Carried forward

This is a high-level comparison, not a substitute for reading the official standard. ISO itself describes the 2026 edition as building on the established framework rather than replacing the fundamental QMS approach.

Common ISO 9001 Audit Mistakes

Many organizations have documented QMS procedures but still receive audit findings because implementation is weak.

Common problems include:

1. Quality is treated as the Quality Department’s responsibility

Quality should be integrated into normal business management.

2. Risk registers are prepared only for audits

Risks should support real decision-making.

3. Quality objectives are not monitored

A target without measurement and action is not effective management.

4. Training is completed, but effectiveness is not evaluated

Attendance is not the same as competence.

5. Internal audits check documents rather than processes

Auditors should verify implementation and effectiveness.

6. Corrective actions address symptoms

Root cause should be investigated and effectiveness verified.

7. Management review becomes a routine presentation

Management review should produce meaningful decisions and actions.

8. Supplier performance is not actively monitored

Supplier problems can directly affect customer satisfaction.

9. Obsolete documents remain available at points of use

Document control must work in practice.

10. Employees cannot explain how their work affects quality

This can indicate a weakness in awareness and quality culture.

How to Prepare for an ISO 9001:2026 Audit

Before an audit, conduct a practical readiness review.

Ask:

Can employees explain the Quality Policy?
Do employees understand relevant quality objectives?
Can process owners explain their process KPIs?
Are risks and opportunities actively managed?
Are quality objectives being achieved?
Are customer complaints analyzed?
Are suppliers monitored?
Are measuring instruments calibrated?
Are internal audits effective?
Are corrective actions closed and verified?
Does management act on QMS performance?
Can employees demonstrate their contribution to quality?
Is quality culture visible in daily operations?
Are process records complete and traceable?
Are improvement actions producing measurable results?

The best preparation is not creating documents immediately before the audit.

It is making sure that the QMS is actually working every day.

Conclusion

ISO 9001:2026 should not be viewed simply as a new certification requirement.

It is an opportunity to make the Quality Management System more closely connected with:

Business strategy
Leadership
Quality culture
Customer requirements
Risks and opportunities
Employee involvement
Process performance
Continual improvement

The 10-clause structure remains familiar, but organizations should pay particular attention to the revised edition’s stronger emphasis on leadership, quality culture, accountability, strategic alignment, risks and opportunities and clearer application of requirements.

For a successful QMS, remember this simple flow:

Context → Leadership → Planning → Support → Operation → Performance Evaluation → Improvement

The objective is not simply to pass an ISO audit.

The objective is to build a QMS that helps the organization consistently meet customer requirements, control processes, make better decisions and continually improve performance.
