ISO 19011:2026 Training - Guidelines for Auditing Management Systems for Internal Auditors, Supplier Auditors and Lead Auditors

ISO 19011:2026 Training – Guidelines for Auditing Management Systems for Internal Auditors, Supplier Auditors and Lead Auditors

ISO 19011:2026 Training provides practical knowledge and auditing skills for professionals responsible for conducting, managing and leading audits of management systems. The course is designed for Internal Auditors, Supplier Auditors, Second-Party Auditors, Lead Auditors, Audit Team Leaders, Quality Managers, HSE Managers, Compliance Professionals and Management System Consultants.

ISO 19011:2026 is the current fourth edition of the international guidelines for auditing management systems. It was published in May 2026 and replaces ISO 19011:2018. The standard provides guidance on auditing principles, audit programme management, conducting management-system audits, and evaluating the competence of people involved in the audit process.

The 2026 edition responds to changes in how organizations operate, including the growing use of technology, digitization and virtual environments, while placing increased emphasis on risk analysis and mitigation.

This ISO 19011:2026 training is therefore designed not simply to teach auditors how to use an audit checklist, but to develop the ability to plan audits, collect objective evidence, evaluate conformity, identify meaningful findings, communicate with auditees, prepare audit reports and verify corrective actions.

1. What Is ISO 19011:2026?

ISO 19011:2026 – Guidelines for auditing management systems is an international standard providing guidance for organizations and auditors that need to plan and conduct management-system audits or manage an audit programme.

ISO 19011:2026 covers:

• Principles of auditing
• Managing an audit programme
• Planning audits
• Conducting audit activities
• Collecting and evaluating audit evidence
• Preparing audit conclusions
• Reporting audit results
• Evaluating auditor competence
• Developing auditors and audit teams

The official ISO Online Browsing Platform identifies ISO 19011:2026 as the fourth edition, published in May 2026. Its scope covers management-system auditing and competence evaluation for individuals involved in the audit process, including people managing audit programmes, auditors and audit teams.

2. Is ISO 19011:2026 a Certification Standard?

No. ISO 19011:2026 is an auditing guideline, not a management-system certification standard.

This distinction is important.

For example:

• ISO 9001 specifies requirements for a Quality Management System.
• ISO 14001 specifies requirements for an Environmental Management System.
• ISO 45001 specifies requirements for an Occupational Health and Safety Management System.
• ISO 27001 specifies requirements for an Information Security Management System.
• ISO 19011:2026 provides guidance on how management-system audits can be planned and conducted.

ISO specifically states that using ISO 19011 does not itself lead to certification. Instead, it supports auditing of management systems such as ISO 9001 and ISO 14001.

Therefore, appropriate terminology includes:

ISO 19011:2026 Training

ISO 19011:2026 Auditor Training

Management System Auditor Training Based on ISO 19011:2026

rather than presenting ISO 19011:2026 as a certification scheme.

3. Why Is ISO 19011:2026 Important for Auditors?

An effective management-system auditor must do more than compare documents against a checklist.

The auditor needs to determine whether:

Requirements → Processes → Controls → Implementation → Evidence → Effectiveness

are appropriately connected.

For example, an auditor should not simply ask whether a procedure exists. The auditor should determine:

• What requirement applies?
• What process implements the requirement?
• Who is responsible?
• What controls are established?
• What records or other evidence demonstrate implementation?
• How is effectiveness evaluated?
• What happens when the process does not achieve its intended result?

ISO 19011:2026 provides a structured framework for conducting these activities. ISO also describes the standard as supporting standardized audit methodology, audit-programme management, auditor competence and continual improvement through auditing.

4. Who Should Attend ISO 19011:2026 Auditor Training?

The course is particularly suitable for professionals performing or managing:

Internal Audits

• Internal Auditors
• QMS Internal Auditors
• EMS Internal Auditors
• OH&S Internal Auditors
• ISMS Internal Auditors
• IMS Internal Auditors
• Quality Engineers
• QA/QC Managers
• HSE/EHS Personnel
• Compliance Personnel

Supplier Audits

• Supplier Auditors
• Second-Party Auditors
• Supplier Quality Engineers
• Supplier Development Engineers
• Procurement Quality Personnel
• Supplier Compliance Auditors
• Customer-specific supplier-audit teams

Lead and Audit-Team Roles

• Lead Auditors
• Audit Team Leaders
• Audit Programme Managers
• Management System Managers
• Quality Managers
• IMS Managers
• Management Representatives
• Certification-audit preparation teams
• Management-system consultants

The standard is applicable to organizations that need to conduct internal or external management-system audits or manage an audit programme.

5. ISO 19011:2026 Training for Internal Auditors

An Internal Auditor evaluates the organization's own management system against defined audit criteria.

The training develops skills in:

• Understanding audit criteria
• Preparing an internal audit programme
• Planning individual audits
• Reviewing documented information
• Preparing audit checklists
• Conducting process-based audits
• Interviewing employees
• Sampling records
• Observing activities
• Collecting objective evidence
• Identifying nonconformities
• Writing audit findings
• Preparing audit reports
• Following up corrective actions
• Verifying corrective-action effectiveness

The objective is to move internal auditing from a simple “check-the-box” exercise toward an audit process that provides useful information about management-system conformity and effectiveness.

6. ISO 19011:2026 Training for Supplier Auditors

Supplier auditing is generally a second-party audit in which an organization evaluates a supplier or external provider against specified requirements.

A supplier audit may include:

• Management-system requirements
• Customer-specific requirements
• Product-quality requirements
• Process requirements
• Supplier performance
• Regulatory requirements
• Environmental requirements
• Occupational health and safety requirements
• Delivery performance
• Traceability
• Special processes
• Corrective-action performance

The auditor must understand the difference between:

Audit criteria

and

Audit evidence

For example, a customer may require a supplier to control a particular manufacturing process. The supplier auditor should verify how that requirement is actually implemented through procedures, personnel, equipment, process controls, records and performance results.

This makes ISO 19011:2026 particularly useful for organizations managing complex global supply chains.

7. ISO 19011:2026 Training for Lead Auditors and Audit Team Leaders

A Lead Auditor or Audit Team Leader has responsibilities beyond conducting individual interviews.

The role may involve:

• Establishing audit objectives
• Defining audit scope
• Determining audit criteria
• Selecting audit team members
• Assigning audit responsibilities
• Preparing the audit plan
• Coordinating audit activities
• Managing communication with the auditee
• Controlling audit time
• Resolving issues within the audit team
• Consolidating audit evidence
• Reviewing audit findings
• Leading the closing meeting
• Preparing or approving the audit report
• Coordinating audit follow-up

The course therefore develops both technical auditing skills and audit-team management skills.

8. ISO 19011:2026 Audit Principles

ISO 19011:2026 establishes fundamental principles for auditing.

The current standard identifies principles including:

• Integrity
• Fair presentation
• Due professional care
• Confidentiality
• Independence
• Evidence-based approach
• Risk-based approach

These principles provide the foundation for credible and consistent auditing.

Integrity

Auditors should perform their work honestly, responsibly and professionally.

Fair Presentation

Audit findings, conclusions and reports should accurately reflect audit activities and evidence.

Due Professional Care

Auditors should exercise appropriate judgment and diligence according to the importance and complexity of the audit.

Confidentiality

Audit information should be appropriately protected.

Independence

Auditors should avoid conflicts of interest and maintain appropriate objectivity.

Evidence-Based Approach

Audit conclusions should be based on verifiable information rather than assumptions.

Risk-Based Approach

Audit planning and execution should consider risks and opportunities that may affect achievement of audit objectives.

9. Audit Programme Management According to ISO 19011:2026

One of the important areas of ISO 19011:2026 is managing an audit programme.

The programme may involve multiple audits conducted over a defined period.

Training can cover:

• Establishing audit programme objectives
• Determining audit programme risks and opportunities
• Establishing the audit programme
• Selecting audit methods
• Assigning auditors
• Managing resources
• Implementing audits
• Monitoring the programme
• Reviewing audit results
• Improving the audit programme

The current ISO 19011:2026 structure specifically includes audit-programme risks and opportunities and the monitoring, review and improvement of the programme.

10. Audit Planning Training

A competent auditor should know how to convert audit objectives into a practical audit plan.

The training covers how to define:

Audit Objective

What is the audit intended to determine?

Audit Scope

Which locations, departments, processes, products, activities or functions are included?

Audit Criteria

Against what requirements will conformity be evaluated?

Examples include:

• ISO standards
• Company procedures
• Customer requirements
• Legal requirements
• Contractual requirements
• Internal specifications
• Supplier requirements

Audit Methods

Depending on the situation, auditing may include:

• On-site audit
• Remote audit
• Interviews
• Document review
• Observation
• Sampling
• Record review
• Process tracing
• Data analysis

11. Audit Checklist Development

An audit checklist should support the auditor rather than replace professional judgment.

A good checklist can connect:

Requirement → Process → Question → Evidence → Finding

For example:

Requirement: Supplier evaluation

Audit Question: How does the organization evaluate supplier performance?

Evidence: Approved supplier list, evaluation records, supplier scorecards, corrective-action records.

Effectiveness Question: How does the organization determine whether supplier controls are effective?

This approach helps auditors avoid asking only theoretical questions

12. Audit Interview Skills

Interviewing is one of the most important practical auditor skills.

The training can teach auditors how to use:

Open Questions

“What is your process for controlling this activity?”

Follow-Up Questions

“What happens if the required result is not achieved?”

Evidence Questions

“Can you show me the relevant record?”

Effectiveness Questions

“How do you know this control is effective?”

Traceability Questions

“Can we follow one example from input through the completed process?”

The auditor should listen carefully, verify information and avoid leading the auditee toward a predetermined conclusion.

13. Objective Evidence in ISO 19011:2026 Auditing

Audit conclusions should be supported by objective evidence.

Examples include:

• Documents
• Records
• Data
• Measurements
• Interviews
• Direct observations
• System information
• Process outputs
• Performance results
• Monitoring records
• Training records
• Inspection results
• Corrective-action records

The auditor should distinguish between:

Statement

and

Verified Evidence

For example:

“Employees are trained.”

is an assertion.

A stronger audit approach asks:

• Who was trained?
• What training was provided?
• When?
• Against what competence requirement?
• What evidence demonstrates completion?
• How was competence evaluated?

14. Risk-Based Auditing According to ISO 19011:2026

Risk-based auditing is particularly important in complex manufacturing and global supply-chain environments.

Audit resources can be prioritized according to factors such as:

• Process criticality
• Customer requirements
• Regulatory significance
• Previous audit findings
• Repeated nonconformities
• Process changes
• New technology
• Supplier risk
• Environmental significance
• OH&S risk
• Information-security risk
• Business continuity considerations

ISO/TC 176 notes that ISO 19011:2026 responds to changes in organizational operations, particularly technology, digitization and virtual environments, and places increased focus on risk analysis and mitigation.

15. Digital and Remote Auditing Skills

Modern organizations increasingly use digital systems and remote working environments.

ISO 19011:2026 addresses the changing operational environment, including technology, digitization and virtual environments.

Training can therefore include practical considerations for:

• Remote interviews
• Video conferencing
• Digital records
• Electronic management systems
• Remote observation
• Secure evidence sharing
• Digital sampling
• Access control
• Cybersecurity considerations
• Maintaining audit integrity in virtual environments

The auditor must ensure that remote methods still provide sufficient and reliable audit evidence.

16. Conducting the Audit

The practical audit process can be structured as:

Initiate → Plan → Prepare → Conduct → Evaluate Evidence → Report → Follow Up

Audit Opening Meeting

The auditor confirms:

• Audit objectives
• Scope
• Criteria
• Schedule
• Methods
• Communication arrangements
• Confidentiality
• Safety requirements

Audit Investigation

The auditor:

• Interviews personnel
• Reviews documents
• Samples records
• Observes processes
• Traces activities
• Collects evidence
• Evaluates conformity

Audit Team Review

For team audits, auditors consolidate evidence and discuss potential findings.

Closing Meeting

The audit team presents:

• Audit results
• Findings
• Conclusions
• Required follow-up

17. How to Write an Effective Audit Finding

One of the most important practical skills is writing a clear audit finding.

A strong finding should connect:

Requirement + Objective Evidence + Nonconformity

For example:

Requirement: The organization shall evaluate supplier performance according to its defined criteria.

Objective Evidence: During the audit, supplier XYZ was listed as an approved supplier, but no documented performance evaluation was available for the previous evaluation period required by the organization's procedure.

Finding: The organization did not demonstrate implementation of its defined supplier-performance evaluation process for supplier XYZ.

This is substantially stronger than writing:

“Supplier evaluation is not good.”

The second statement is subjective and does not clearly establish the audit evidence.

18. Audit Conclusions and Reporting

The audit report should provide information that is:

• Accurate
• Clear
• Relevant
• Evidence-based
• Traceable
• Understandable

Depending on the audit objectives, the report may include:

• Audit objectives
• Scope
• Criteria
• Audit team
• Audit dates
• Locations
• Summary of activities
• Conformities
• Nonconformities
• Opportunities for improvement, where applicable
• Audit conclusions
• Follow-up requirements

The report should distinguish factual audit results from unsupported opinions.

19. Corrective Action and Audit Follow-Up

Auditing does not end when the audit report is issued.

The auditor or audit programme manager may need to evaluate:

1. Correction
2. Root-cause analysis
3. Corrective action
4. Implementation
5. Evidence of completion
6. Effectiveness
7. Closure

Typical root-cause techniques may include:

• 5 Whys
• Fishbone / Ishikawa
• Process analysis
• Cause-and-effect analysis
• Data and trend analysis

A corrective action should address the cause of the nonconformity rather than merely correcting the immediate symptom.

20. Auditor Competence and Evaluation

ISO 19011:2026 provides guidance concerning the competence and evaluation of people involved in auditing.

Auditor competence can involve a combination of:

• Audit knowledge
• Audit skills
• Management-system knowledge
• Sector knowledge
• Technical knowledge
• Communication skills
• Interviewing skills
• Analytical ability
• Professional judgment
• Appropriate experience

Organizations should therefore consider auditor competence as an ongoing development process rather than simply a one-time training event.

21. Internal Auditor vs Supplier Auditor vs Lead Auditor

Auditor Role	Main Purpose	Typical Responsibilities
Internal Auditor	Audit the organization's own management system	Plan and conduct internal audits, collect evidence, identify findings and report results
Supplier / Second-Party Auditor	Evaluate suppliers or external providers	Assess supplier conformity, capability, controls, performance and customer requirements
Lead Auditor / Audit Team Leader	Lead an audit or audit team	Plan, coordinate, manage the team, review findings, lead meetings and finalize audit conclusions
Audit Programme Manager	Manage a programme of audits	Establish objectives, manage resources, monitor performance and improve the audit programme

A single professional may perform more than one of these roles depending on the organization's structure and competence requirements.

22. ISO 19011:2026 Training for Different Management Systems

ISO 19011:2026 can support auditing of many types of management systems.

Examples include:

Quality

• ISO 9001
• IATF 16949
• AS9100
• ISO 13485

Environment

• ISO 14001
• Environmental compliance systems

Occupational Health and Safety

• ISO 45001

Information Security

• ISO/IEC 27001

Energy

• ISO 50001

Business Continuity

• ISO 22301

Laboratory and Related Systems

• ISO/IEC 17025

The auditor must still possess the specific competence and knowledge needed for the management system, industry and audit objectives. ISO 19011 provides general auditing guidance; it does not replace the technical requirements of the standard being audited.

23. Integrated Management System Auditing

Organizations operating multiple ISO management systems can use ISO 19011:2026 as a common auditing framework.

For example, an integrated audit may examine:

ISO 9001 + ISO 14001 + ISO 45001

within a single manufacturing process.

The auditor may evaluate:

Quality

• Process control
• Customer requirements
• Product conformity
• Supplier performance

Environment

• Environmental aspects
• Waste
• Emissions
• Operational controls
• Compliance obligations

OH&S

• Hazard identification
• Risk controls
• PPE
• Machine safety
• Emergency preparedness

This integrated approach can reduce duplication while maintaining the specific audit criteria applicable to each management system.

A practical exercise may simulate an internal audit of a manufacturing process.

Participants receive:

• Management-system requirements
• Procedures
• Process information
• Records
• Employee interviews
• Sample evidence

They must determine:

1. What should be audited?
2. What evidence should be collected?
3. What questions should be asked?
4. Is the process conforming?
5. Is there sufficient evidence for a finding?
6. How should the finding be written?
7. What should be included in the audit report?

This exercise helps transform theoretical knowledge into practical auditor skills.

26. Practical Supplier Audit Exercise

For supplier auditing, participants may evaluate a simulated supplier against:

• Quality requirements
• Process controls
• Supplier management
• Product inspection
• Traceability
• Corrective actions
• Customer requirements

The exercise can include actual supplier-audit scenarios such as:

• Repeated quality problems
• Late delivery
• Incomplete records
• Process changes
• Unqualified personnel
• Inadequate corrective actions

The auditor must determine which findings are supported by objective evidence.

27. Practical Lead Auditor Exercise

A Lead Auditor exercise can include:

• Selecting the audit team
• Assigning audit responsibilities
• Preparing the audit plan
• Conducting an opening meeting
• Managing audit-team communication
• Reviewing evidence
