ISO 9001:2026 & ISO 19011:2026 Auditor Training - Internal, Supplier and Management System Auditors

ISO 9001:2026 & ISO 19011:2026 Auditor Training - Internal, Supplier and Management System Auditors

ISO 9001:2026 & ISO 19011:2026 Auditor Training is designed to develop practical auditing competence for Internal Auditors, Supplier Auditors, Second-Party Auditors and Management System Auditors. The training combines the requirements of ISO 9001:2026 Quality Management Systems with the auditing principles and methodologies provided by ISO 19011:2026 Guidelines for Auditing Management Systems.

For organizations operating in global supply chains, particularly FDI manufacturers, automotive suppliers, electronics manufacturers, supporting industries and companies managing multiple suppliers, effective auditing is no longer limited to checking whether documents exist. Auditors need to understand processes, evaluate objective evidence, identify risks, determine conformity, communicate findings and assess whether corrective actions address the underlying causes.

VINTECOM International provides ISO 9001:2026 Auditor Training and ISO 19011:2026 Auditor Training with a practical approach focused on process-based auditing, risk-based thinking, objective evidence, audit interviewing, supplier assessment and effective audit reporting.

1. What is ISO 9001:2026 Auditor Training?

ISO 9001:2026 Auditor Training provides auditors with the knowledge and practical skills necessary to audit a Quality Management System against the requirements of ISO 9001:2026.

The training focuses not only on understanding individual clauses but also on understanding how the requirements are implemented through organizational processes.

An ISO 9001:2026 auditor should be able to:

• Understand the requirements of ISO 9001:2026.
• Identify applicable audit criteria.
• Plan and prepare an audit.
• Understand organizational processes and their interactions.
• Identify risks and opportunities relevant to the audit.
• Collect and verify objective evidence.
• Conduct effective interviews.
• Use sampling appropriately.
• Evaluate conformity and nonconformity.
• Record clear and evidence-based audit findings.
• Evaluate root causes and corrective actions.
• Prepare an effective audit report.
• Follow up on corrective actions.
• Communicate audit results professionally.

The objective is therefore not simply to teach auditors how to use an audit checklist, but to develop the ability to determine whether the management system is effectively implemented and controlled.

2. What is ISO 19011:2026 and why is it important for auditors?

ISO 19011:2026 – Guidelines for Auditing Management Systems provides guidance on the principles of auditing, managing audit programmes, conducting management system audits and evaluating the competence of people involved in the audit process.

ISO 19011:2026 is an auditing guideline, not a management system certification standard.

This distinction is important:

• ISO 9001:2026 specifies requirements for a Quality Management System.
• ISO 19011:2026 provides guidance for auditing management systems.
• ISO 9001 can be used as audit criteria when conducting an ISO 9001 audit.
• ISO 19011 helps auditors determine how an audit programme and individual audits should be planned, conducted, documented and followed up.

Therefore, an ISO 9001:2026 & ISO 19011:2026 Auditor Training course combines two complementary areas:

What should the organization comply with? → ISO 9001:2026

How should the management system be audited effectively? → ISO 19011:2026

3. ISO 9001:2026 and the new context for auditors

ISO 9001:2026 is the sixth edition of ISO 9001 and was published in September 2026, replacing ISO 9001:2015.

The revision maintains the fundamental process approach and quality management principles while providing updates intended to improve clarity, usability and relevance. The revised standard also places greater emphasis on areas such as leadership, organizational accountability, risks and opportunities, and the relationship between quality management and the organization's broader context.

For auditors, this means that auditing should not become a simple clause-by-clause document review.

Auditors need to understand:

• The organization's context.
• Relevant interested parties.
• Organizational risks and opportunities.
• Quality objectives.
• Process performance.
• Leadership involvement.
• Operational controls.
• Monitoring and measurement.
• Evaluation of performance.
• Improvement activities.
• Interactions between processes.

A mature auditor therefore asks questions such as:

“Show me how this process works.”

rather than simply:

“Do you have a documented procedure?”

The auditor then follows the process through objective evidence.

4. ISO 19011:2026 and the development of modern auditing

The 2026 edition of ISO 19011 responds to changes in the way management system audits are conducted, including greater use of technology, digital information and virtual or remote audit environments.

Modern auditing can involve:

• Electronic records.
• Cloud-based management systems.
• Digital production records.
• ERP and MES systems.
• Remote interviews.
• Online document review.
• Digital audit trails.
• Data analysis.
• Remote or hybrid audits.
• Technology-assisted evidence collection.

This creates additional considerations for auditors.

For example, an auditor may need to determine:

• Whether electronic evidence is reliable.
• Whether access controls affect the evidence available.
• Whether remote interviews provide sufficient information.
• Whether sampling is representative.
• Whether digital records can be traced to the relevant process.
• Whether audit risks change when an audit is conducted remotely.

ISO 19011:2026 therefore supports an auditing approach that considers both audit effectiveness and audit risk.

5. Internal Auditor Training

Internal auditors evaluate the organization's own management system.

An effective ISO 9001:2026 Internal Auditor Training program should therefore develop the ability to audit independently and objectively while understanding the organization's operational environment.

Typical internal audit activities include:

Audit programme management

The organization should determine:

• What processes need to be audited.
• How frequently they should be audited.
• Which risks should influence audit frequency.
• Who should conduct the audit.
• What audit criteria will be used.
• How audit results will be followed up.

Audit planning

The auditor prepares:

• Audit scope.
• Audit objectives.
• Audit criteria.
• Audit schedule.
• Audit team.
• Process sequence.
• Sampling approach.
• Required resources.

Conducting the audit

The auditor then:

1. Holds the opening meeting.
2. Reviews relevant information.
3. Interviews personnel.
4. Observes activities.
5. Examines records.
6. Traces processes.
7. Verifies objective evidence.
8. Evaluates conformity.
9. Records findings.
10. Conducts the closing meeting.

The emphasis should remain on evidence rather than assumptions.

6. Supplier Auditor and Second-Party Auditor Training

For companies operating complex supply chains, Supplier Auditor Training is particularly important.

A supplier audit is generally a second-party audit, where an organization evaluates another organization in its supply chain.

Supplier audits may assess:

• Quality management systems.
• Manufacturing processes.
• Product quality controls.
• Incoming materials.
• Production controls.
• Special processes.
• Traceability.
• Measurement and testing.
• Change management.
• Nonconforming product control.
• Corrective action.
• Delivery performance.
• Customer-specific requirements.
• Environmental and occupational health and safety controls where applicable.

A supplier auditor should not simply copy an ISO 9001 internal audit checklist.

The audit criteria should be established according to the purpose and scope of the supplier evaluation.

For example, an automotive supplier audit may combine:

• ISO 9001 requirements.
• IATF 16949 requirements where applicable.
• Customer-specific requirements.
• VDA requirements.
• AIAG Core Tools.
• Product and process requirements.
• Supplier quality requirements.
• Specific purchase specifications.

This is why supplier auditor competence requires both management-system auditing skills and technical understanding of the supply chain.

7. Management System Auditor Competence

An auditor's competence consists of more than knowledge of ISO clauses.

A competent auditor needs a combination of:

Knowledge

Understanding:

• ISO 9001:2026.
• ISO 19011:2026.
• Management system principles.
• Process approach.
• Risk-based thinking.
• Audit principles.

Skills

Ability to:

• Plan audits.
• Interview personnel.
• Listen actively.
• Follow audit trails.
• Evaluate evidence.
• Sample records.
• Identify gaps.
• Write findings.
• Communicate effectively.

Experience

Auditors should understand the operational environment in which they conduct audits.

For example, auditing a manufacturing process requires an understanding of:

• Production flow.
• Equipment.
• Process parameters.
• Inspection points.
• Measurement systems.
• Traceability.
• Nonconforming products.
• Maintenance.
• Competence.
• Process performance.

An auditor does not necessarily need to be a technical specialist in every area, but the audit team must collectively possess the competence required for the audit scope.

8. Risk-Based Auditing

One of the key areas of practical auditor training is risk-based auditing.

Instead of allocating identical audit time to every process, the auditor considers the relative importance and risks associated with different processes.

For example:

Process	Potential Audit Focus
Purchasing	Supplier risks, incoming quality, supplier evaluation
Production	Process controls, parameters, defects, traceability
Quality Control	Inspection methods, records, measurement equipment
Maintenance	Equipment reliability, preventive maintenance
Warehouse	Identification, preservation, FIFO/FEFO where applicable
Engineering	Design/change control, technical specifications
Customer Service	Complaints, customer requirements, feedback
Management	Objectives, resources, performance evaluation

The purpose is not to automatically classify a process as “high risk” or “low risk.”

The auditor needs to understand the organization's actual circumstances and determine where audit attention can provide meaningful assurance.

9. Evidence-Based Auditing

A professional auditor should distinguish between:

Statement → Evidence → Evaluation → Conclusion

For example:

An employee says:

“All operators have been trained.”

The auditor should not immediately record conformity.

The auditor may verify:

• Training records.
• Competence criteria.
• Training content.
• Evaluation results.
• Authorization records.
• Practical competence.
• Relevant job requirements.

The audit conclusion should be based on verified evidence.

This is the foundation of evidence-based auditing.

10. Audit Interview Techniques

Interviewing is one of the most important practical skills for an auditor.

Poor questions often produce limited information.

For example:

Weak question:

“Do you follow the procedure?”

Better question:

“Please show me how this process is performed.”

The auditor can then follow the process:

Requirement → Process → Activity → Record → Result

Useful audit questions include:

• How do you know what the current requirement is?
• Who is responsible for this activity?
• What happens when the requirement is not met?
• How do you monitor this process?
• What records demonstrate that the activity was completed?
• What risks have you identified?
• What changes have occurred recently?
• How do you evaluate process effectiveness?
• What corrective action was taken after the previous issue?

These questions help the auditor move from document review to process verification.

11. Audit Sampling

An audit cannot normally examine every single record, transaction or product.

Auditors therefore use sampling.

Training should explain how to establish a reasonable sample based on:

• Audit objectives.
• Process complexity.
• Risk.
• Previous audit findings.
• Volume of activities.
• Changes.
• Performance trends.
• Available audit time.

Sampling should be sufficiently justified to support the audit conclusion.

Auditors should also understand the limitation of sampling.

Finding no problem in a sample does not automatically prove that the entire population is free from nonconformity.

12. Nonconformity Identification and Writing

One of the most important auditor competencies is writing a clear nonconformity.

A useful nonconformity statement should identify:

Requirement + Objective Evidence + Gap

For example:

Requirement: The organization is required to maintain defined records demonstrating completion of inspection activities.

Evidence: During the audit, inspection records for selected production lots were reviewed and records for two sampled lots did not contain the required inspection results.

Gap: The available evidence does not demonstrate that the specified inspection records were consistently maintained for the sampled lots.

This is more useful than writing:

“Inspection records are not properly maintained.”

The second statement is too general and does not provide sufficient evidence.

13. Root Cause and Corrective Action

Auditors also need to understand the difference between:

• Correction.
• Corrective action.
• Root cause.
• Effectiveness verification.

For example:

Problem: A required inspection record is missing.

Correction: Reconstruct the missing record where objective evidence exists.

Root cause analysis: Determine why the record was not generated or controlled.

Corrective action: Modify the process, responsibility, system or control to prevent recurrence.

Effectiveness verification: Determine whether the corrective action actually prevents recurrence.

The auditor should avoid accepting superficial corrective actions such as:

“Retrain the employee.”

Training may be appropriate, but the auditor should ask whether the actual cause was:

• unclear responsibility;
• inadequate procedure;
• system design;
• workload;
• insufficient supervision;
• missing automation;
• unclear requirements;
• ineffective monitoring.

14. Audit Reporting

An effective audit report should communicate the results clearly to management and relevant process owners.

Typical information may include:

• Audit objective.
• Audit scope.
• Audit criteria.
• Audit dates.
• Audit team.
• Processes audited.
• Summary of evidence.
• Conformities.
• Nonconformities.
• Opportunities for improvement where appropriate.
• Follow-up requirements.
• Overall audit conclusion.

The report should remain factual and evidence-based.

An auditor should avoid emotional or subjective language.

15. Practical Training Methodology

VINTECOM's approach to auditor training emphasizes practical application rather than only theoretical clause interpretation.

Training activities can include:

Case studies

Participants analyze realistic organizational situations.

Audit role play

Participants work as:

• Lead auditor.
• Auditor.
• Auditee.
• Process owner.

Audit interviews

Participants practice:

• Opening questions.
• Process questions.
• Evidence verification.
• Follow-up questions.
• Closing questions.

Audit trail exercises

Participants learn how to follow evidence from one process to another.

Nonconformity writing exercises

Participants review evidence and write audit findings.

Corrective action evaluation

Participants evaluate whether proposed corrective actions address the actual cause.

Mock audit

Participants conduct a simulated audit from planning through reporting.

This approach allows participants to practice the complete audit cycle.

18. Application to FDI and Global Supply Chains

For FDI companies and suppliers participating in global supply chains, auditing competence is closely connected with supplier development and risk management.

A supplier auditor may need to evaluate not only whether the supplier has an ISO certificate, but also whether the supplier's processes actually deliver consistent results.

For example:

Supplier requirement → Process capability → Production control → Inspection → Product conformity → Customer performance

This approach is particularly useful in sectors such as:

• Automotive.
• Electronics.
• Electrical equipment.
• Mechanical components.
• Precision manufacturing.
• Medical devices.
• Industrial equipment.
• Aerospace.
• Supporting industries.

VINTECOM's training and consulting approach can be adapted to the organization's industry, customer requirements and supply-chain structure.

19. ISO 9001:2026 Auditor Training vs. ISO 19011:2026 Training

These two subjects are related but not identical.

ISO 9001:2026	ISO 19011:2026
Quality Management System requirements	Auditing management system guidance
Defines what the QMS should address	Provides guidance on how to audit
Used as audit criteria	Used as auditing methodology guidance
Applies to organizations implementing QMS	Applies to organizations conducting management system audits
Supports conformity evaluation	Supports effective audit planning and execution

A combined course allows auditors to understand both sides of the audit:

The requirements being audited + the methodology used to conduct the audit.
