Understanding Internal Audits and Their Importance

Internal audits are systematic, objective assessments of an organization's processes, procedures, and activities. They are conducted by internal auditors who are independent of the processes they are auditing. The primary goal of internal audits is to evaluate the effectiveness, efficiency, and compliance of an organization's quality management system.

For organizations seeking IATF 16949 compliance, internal audits are critical in identifying areas that require improvement and assessing adherence to the standard's requirements. These audits provide valuable insights, allowing organizations to take corrective actions, optimize processes, and align their quality management systems with industry best practices.

Preparing for Internal Audits

Preparing for Internal Audits

1. Establishing an Internal Audit Program

Before conducting internal audits, organizations must develop a well-defined internal audit program. This program outlines the scope, frequency, and objectives of the audits. It also defines the roles and responsibilities of internal auditors and provides guidelines for audit planning and execution.

2. Selecting Competent Internal Auditors

Selecting competent and trained internal auditors is crucial to the success of the audit program. Internal auditors should possess a comprehensive understanding of IATF 16949 requirements, audit principles, and relevant automotive industry practices. Investing in internal auditor training ensures that auditors can effectively assess the organization's compliance.

3. Creating an Audit Schedule

Developing a detailed audit schedule is essential for ensuring that all relevant processes and areas are audited regularly. The audit schedule should consider the organization's size, complexity, and operational requirements. Audits should cover all aspects of the quality management system, including processes, documentation, and personnel competence.

4. Audit Planning

Effective audit planning is critical to conducting thorough and systematic audits. Before the audit, auditors should review relevant documents, process manuals, and previous audit reports. They should also communicate with process owners and key stakeholders to understand the processes and gather necessary information.

Conducting the Internal Audit

Conducting the Internal Audit

1. Opening Meeting

Each internal audit should commence with an opening meeting. During this meeting, auditors introduce themselves, explain the audit's purpose and scope, and outline the audit process. The opening meeting is also an opportunity to address any concerns or questions from the auditees.

2. Document Review

Auditors should review relevant documents and records to assess the organization's compliance with IATF 16949 requirements. This review includes process documentation, quality manuals, work instructions, and records of non-conformities and corrective actions.

3. Process Observation

During the audit, auditors should observe the processes in action. This involves observing how activities are carried out, verifying that procedures are followed, and assessing the effectiveness of process controls. Auditors may ask questions and seek clarification from process owners and operators.

4. Evidence Gathering

Auditors must gather objective evidence to support their findings and conclusions. Evidence can include records, data, photographs, and interviews. The evidence should be sufficient to demonstrate the organization's compliance or non-compliance with IATF 16949 requirements.

5. Non-conformance Identification

If auditors identify instances of non-conformities during the audit, they should document them clearly. Non-conformities are deviations from IATF 16949 requirements or the organization's own processes. Each non-conformity should be specific, with a clear reference to the standard clause or process requirement.

6. Reporting and Closing Meeting

After completing the audit, auditors should prepare a comprehensive audit report. The report should include the audit findings, non-conformities, and recommendations for improvement. The audit report should be communicated to the relevant stakeholders in a closing meeting.

Implementing Corrective Actions

Upon receiving the audit report, the organization must take prompt and effective corrective actions to address the identified non-conformities. Corrective actions should focus on eliminating the root causes of non-compliance and preventing recurrence.

Implementing Corrective Actions

1. Corrective Action Plans

The organization should develop corrective action plans that outline the specific steps, responsibilities, and timelines for implementing corrective actions. The plans should be realistic, achievable, and aligned with the organization's overall objectives.

2. Follow-up and Verification

After implementing corrective actions, the organization should conduct follow-up audits to verify the effectiveness of the actions taken. Follow-up audits ensure that the identified non-conformities have been adequately addressed and that the quality management system is back in compliance.

Continual Improvement and the Internal Audit Process

The internal audit process should be viewed as an opportunity for continual improvement. Organizations should use the insights gained from audits to enhance their processes, identify best practices, and optimize their quality management system.

Continual Improvement and the Internal Audit Process

1. Lessons Learned

Internal auditors and process owners should regularly review audit findings to identify common themes and trends. Lessons learned from audits can be used to refine procedures, update work instructions, and enhance the organization's overall operational efficiency.

2. Auditing for Improvement

Organizations can adopt a proactive approach to internal auditing by focusing on auditing for improvement rather than just compliance. Audits can be used as a tool to identify areas where processes can be streamlined, waste can be reduced, and customer satisfaction can be enhanced.

3. Feedback Mechanisms

Establishing feedback mechanisms from auditees and other stakeholders can provide valuable insights into the effectiveness of the internal audit process. Feedback can be used to make adjustments to the audit program and improve the overall auditing experience.


Conducting internal audits for IATF 16949 compliance is a crucial aspect of maintaining a robust and efficient quality management system in the automotive industry. By following the best practices outlined in this guide, organizations can ensure that their internal audits are effective, valuable, and contribute to continual improvement. Internal audits not only prepare organizations for external certification audits but also help them achieve operational excellence, customer satisfaction, and a competitive edge in the automotive market.
