22/05/2023by admin0Read: 6 minutes

ISO 9001 internal auditing is the systematic and independent assessment of an organisation’s quality management system (QMS) processes, procedures, and documentation to determine conformity with ISO 9001:2015 regulations. The internal audit’s goal is to establish the effectiveness, adequacy, and conformity of the Quality Management System (QMS), detect non-compliance issues, and make recommendations for improvement.  

Internal Audit involves assessing processes, procedures, records, and performance indicators to find areas for improvement and ensure that the QMS is operating at peak efficiency. 

Internal audits are critical components of the ISO 9001 system because they assist organisations in identifying nonconformities, potential hazards, and opportunities for development. Organisations can analyse their QMS’s performance, identify areas for improvement, and take remedial actions to maintain or improve the system’s efficacy by conducting frequent internal audits.  

This proactive approach assists businesses in achieving continuous improvement, improving customer satisfaction, and demonstrating ISO 9001 compliance.  

Purpose ISO 9001 Internal Audit 

Internal audits are crucial in the implementation and management of an ISO 9001-compliant Quality Management System (QMS). They serve several purposes and bring numerous advantages to organisations pursuing continuous development. The primary goal of internal audits is to ensure that the QMS effectively meets ISO 9001 requirements and assists organisations in meeting their quality objectives. 

Detect nonconformities:  

Internal audits are designed to detect nonconformities or deviations from established procedures, processes, and standards. Auditors conduct systematic reviews of documents, observe practises, and conduct interviews with personnel to find gaps and anomalies. Organisations can take corrective actions to rectify nonconformities and prevent their recurrence by detecting them. 

Assessing Effectiveness:  

Internal audits evaluate the effectiveness of the QMS in delivering the targeted results. Auditors assess if the documented procedures are being followed, whether they are effective in reaching objectives, and whether they are in accordance with ISO 9001 criteria. Organisations can find areas for improvement and optimise their processes by assessing the adoption and effectiveness of the QMS. 

Continuous Improvement:  

Internal audits promote a culture of continual development inside an organisation. Audits provide useful input to organisations by finding nonconformities, observations, and possibilities for change. Auditors evaluate the effectiveness of remedial actions performed in response to prior audits, ensuring that the organisation’s improvement efforts are producing the expected results. 

Risk Identification and Mitigation:  

Internal audits aid in the identification and mitigation of potential risks and vulnerabilities in the QMS. Audits identify areas where risks may exist by analysing processes and procedures, allowing organisations to apply appropriate controls and preventive measures. 

Process Improvement:  

Internal audits help process improvement by identifying nonconformities and observations. Auditors offer important insight into opportunities for streamlining operations, eliminating waste, increasing efficiency, and optimising resource allocation.  

ISO 9001 Internal Audit Process 

The ISO 9001 internal audit process is a critical component of an ISO 9001-based quality management system (QMS). It involves performing an independent and systematic review of an organisation’s processes, procedures, and documentation to ensure compliance with ISO 9001 criteria. Internal audits aid in identifying areas for improvement, assessing the effectiveness of the QMS, and maintaining standard compliance. 

  • Planning: Plan the scope, objectives, and objectives for the internal audit. Create an audit plan, including auditor selection and scheduling. 
  • Preparation: Gather pertinent papers for evaluation, such as the QMS documentation, processes, and records. Prepare any relevant checklists and familiarise auditors with the audit criteria. 
  • Opening Meeting: Conduct an opening meeting to introduce the audit team, communicate the audit goals and scope, and outline the audit process with the auditee. 
  • Audit Execution: Carry out the audit by thoroughly reviewing processes, procedures, and records in relation to the audit criteria. Gather evidence through conducting interviews, observations, and document reviews. Check for conformity with ISO 9001 criteria. 
  • Reporting: Write an audit report summarising nonconformities, observations, and opportunities for improvement based on the audit findings. The report should be concise, straightforward, and objective. 
  • Follow-up: After the audit, work with auditees to rectify any detected non-conformities. Establish corrective and preventive actions to rectify issues and improve the effectiveness of the QMS. 
  • Closing Meeting: Hold a closing meeting to discuss the audit findings, deliver the audit report, and address any questions or concerns raised by auditees. Highlight the need for continual improvement and make recommendations for future audits. 
  • Monitoring and Review: Review the effectiveness of remedial actions on a regular basis and track progress towards addressing non-conformities. Use the internal audit process to assess continuing ISO 9001 compliance and suggest areas for further improvement. 

Organisations may ensure the efficacy of their quality management systems and continuously improve their performance by following this systematic internal audit approach. 

Key Elements of ISO 9001 Internal Audits 

Internal ISO 9001 audits are critical in determining the performance of a company’s quality management system (QMS). There are numerous critical components to conducting successful internal audits: 

Auditors’ Independence and Objectivity:  

Internal auditors should be independent and impartial, devoid of any conflicts of interest that could risk the audit process’s integrity. They must be competent, knowledgeable, and skilled to conduct audits properly. This ensures that auditors can make objective evaluations of the organisation’s QMS. 

Sampling Technique:  

Internal audits often encompass a broad variety of organisational procedures and activities. To choose audit subjects in a representative and methodical manner, sampling procedures are used. 

Evidence Collection and Analysis:  

During an internal audit, auditors gather evidence using a variety of techniques such as interviews, document reviews, observations, and data analysis. This evidence is used to assess the organisation’s compliance with ISO 9001 criteria. Proper documentation and evidence organisation are required for appropriate analysis and reporting. 

Compliance with ISO 9001 criteria:  

The primary goal of an internal audit is to determine whether an organisation is in compliance with ISO 9001 criteria. Auditors compare the documented processes and procedures of the organisation to the requirements of the standard, ensuring that the QMS is effectively implemented and maintained. Corrective actions are identified for non-conformities and areas for improvement. 

Processes, Procedures, and Records Evaluation:  

Internal audits assess the effectiveness and efficiency of an organisation’s processes, procedures, and records. Auditors examine if the documented processes are followed, and whether the procedures are successful in obtaining the desired results and examine records to ensure compliance and traceability. 

Identification of Potential Risks and Opportunities for Improvement: 

Internal audits assist in identifying potential risks and possibilities for improvement in the organisation’s QMS. Auditors evaluate the risks associated with nonconformities, inefficiencies in processes, and customer satisfaction in order to find areas for corrective and preventive action. They also seek ways to improve the QMS, streamline procedures, and improve performance. 

Organisations can perform complete and relevant internal audits by concentrating on these important components, ensuring the continuous improvement of their QMS. 

ISO 9001 Internal Audit Checklist 

The ISO 9001 Internal Audit Checklist is a useful tool for assessing an organisation’s compliance with the ISO 9001 standard, which focuses on quality management systems.  

The checklist covers the important topics that are commonly evaluated during an ISO 9001 internal audit. It assures that the organisation’s quality management system satisfies the certification requirements. 

The checklist addresses critical issues such as the organisation’s scope and context, leadership commitment, strategy development, deployment of resources, operational procedures, performance evaluation, and improvement activities.  

Several actions can be taken to tailor the checklist to unique organisational needs. To begin, determine the organisation’s aims and objectives while keeping risks and customer requirements in mind. 

To ensure compliance, industry-specific rules, and laws should be examined. Customising the checklist’s language and vocabulary is also vital, matching it with the organisation’s own processes and nomenclature. 

Organisations may effectively evaluate their QMS and ensure that it not only satisfies ISO 9001 criteria but also addresses their specific needs and objectives by modifying the internal audit checklist.
