Understanding Internal Audits Key Risks

Internal audits play a crucial role in ensuring the effectiveness of an organization’s management system. They provide an opportunity to identify non-conformities, assess the implementation of processes, and foster continual improvement. However, the process of conducting internal audits has some challenges and risks. Below we’ll explore the key risks associated with internal audits and we’ll present some strategies to mitigate them, particularly within the context of ISO standards; like ISO 9001:2015.

Key Risks In Internal Audits

1. Management Override: Internal auditors may face pressure to align the audit findings with management’s expectations, compromising audit objectivity.
2. Subjectivity and Bias: Auditors may have a close relationship with the department/person being audited, which can compromise the objectivity of the audit findings, leading to inaccurate assessments and ineffective corrective actions.
3. Insufficient Training and Expertise: Auditors lacking proper training and expertise may fail to identify significant issues and risks, or misinterpret ISO requirements. This can result in missed opportunities for improvement and non-conformities going undetected.
4. Inadequate Scope: Misidentification of audit scope or not following the correct identified scope may result in failing to cover all critical areas, missing key risks and issues.
5. Inadequate Documentation: Poor record-keeping of audit processes and findings, and failing to provide clear and actionable audit reports may lead to misunderstanding by the auditees.
6. Inadequate Preparation: Poorly planned audits can lead to incomplete assessments. Without a comprehensive audit plan, critical areas may be overlooked, reducing the internal audit’s effectiveness.
7. Time Pressure: Rushing the audit process due to tight deadlines can lead to uncovered areas/processes during the audit.
8. Inadequate Sampling: Not using a representative sample in the audit can result in misleading findings.
9. Unavailability of conocerned person from auditee: The absence of critical personnel can cause delays in the audit process, impacting timelines and schedules, and impacting the completliness of information provided and the sufficiency of responses. This may also lead to require more follow-up actions and additional meetings to obtain the necessary information, consuming extra time and resources.
10. Resource Constraints: Limited resources, including time and personnel, can restrict the thoroughness and frequency of internal audits. This may prevent a thorough evaluation of all the relevant processes, compromising the internal audit’s comprehensiveness.
11. Confidentiality Breaches: Sensitive information disclosed during the audit process might be inadvertently or deliberately leaked by the auditors, which can lead to exploiting it for personal gain or malicious purposes.
12. Lack of Stakeholder Engagement: Not involving key stakeholders in the audit process may lead to resistance to implementing changes suggested by the internal audit.
13. Communication Gaps: Ineffective communication between auditors and auditees can hinder the audit process. Misunderstandings or lack of clarity regarding audit objectives, findings and recommendations, or personal issues, can create confusion and resistance to corrective actions.
14. Neglecting Follow-Up Audits: Failing to schedule follow-up audits to ensure compliance can result in unresolved issues and recurring problems.

How to Mitigate Risks in Internal Audits

1. Ensuring Auditor Independence and Objectivity: To mitigate bias, organizations should ensure that auditors are independent and not directly involved in the processes they are auditing. Rotating auditors periodically, involving external auditors for critical areas, and having an independent audit committee that oversees the internal audit function and ensures its independence from management, are methods that can be used to enhance audit objectivity.
2. Investing in Auditor Training and Certification: Providing comprehensive training and certification for internal auditors is crucial. Familiarity with ISO standards and auditing techniques ensures that auditors are well-equipped to identify non-conformities in an organization, and are able to suggest effective improvements.
3. Developing a Robust Audit Plan: A detailed audit plan outlining the scope, objectives, criteria, and schedule of internal audits, is essential. It helps ensure that all critical areas are covered and that audits are conducted systematically and thoroughly.
4. Phased Audits: Consider conducting internal audits in phases, focusing on the most critical areas first. This approach can help manage time and resources more effectively.
5. Checklists and Templates: Provide auditors with standardized checklists and templates to guide the documentation process and ensure all necessary information is captured.
6. Random Selection: Use random selection techniques to choose sample units in the audit in order to reduce the risk of misleading findings and ensure that each unit has an equal chance of being selected.
7. Backup Contacts: Identify and document backup contacts or deputies who can provide the necessary information and support if the primary person is unavailable during the audit.
8. Utilize Part-Time Auditors: Engage part-time or contract auditors to supplement the internal audit team during peak periods or for specific projects.
9. Audit Trails: Maintain detailed audit trails to track who accessed sensitive information, when, and for what purpose, limit data sharing to the necessary amount of sensitive information required for the audit only, avoid sharing full datasets unless absolutely necessary, and use the concerned person’s (auditee) device instead of giving access to the auditor’s device.
10. Flexible Scheduling: Be flexible with scheduling to accommodate the availability of key stakeholders, ensuring they can participate without significant disruptions to their own responsibilities. And conduct post-audit review session with stakeholders to discuss audit findings and recommendations, and gather their feedback for future audits.
11. Enhancing Communication and Feedback Mechanisms: Effective communication is a key to a successful audit. Auditors should clearly explain the purpose, scope, and findings of the audit to the auditee in order for the latter to implement the required corrective actions.
12. Develop a Follow-Up Audit Schedule: Establish a clear and detailed follow-up audit schedule as part of the initial audit plan, and include specific timelines and deadlines for follow-up activities.
13. Allocating Sufficient Resources Organizations should allocate adequate resources for internal audits. This includes ensuring that auditors have enough time to conduct thorough assessments and that the necessary tools and support are available to facilitate the audit process.

Connecting Internal Audits to ISO Standards

Internal audits are a critical component of ISO standards, like ISO 9001:2015, which emphasizes the importance of regular audits to monitor and improve the QMS effectiveness. Here’s how internal audits align with key ISO 9001 requirements:

• Clause 9.2: Internal Audit: ISO 9001 requires organizations to conduct internal audits at planned intervals to provide information on whether the QMS conforms to the organization’s requirements and standard’s requirements, and is effectively implemented and maintained. Effective internal audits ensure compliance and identify opportunities for improvement, contributing to overall quality enhancement.
• Clause 10: Improvement: The findings from internal audits feed into the organization’s continual improvement process. By identifying non-conformities and potential improvements; internal audits help organizations align their processes with strategic objectives and customers’ requirements, fostering a culture of continuous improvement.

Conclusion: Striking the Right Balance

Internal audits are instrumental in maintaining the integrity and effectiveness of an organization’s management system. By understanding and mitigating the key risks associated with internal audits, organizations can ensure more accurate, objective, and comprehensive assessments. This in turn, supports compliance with ISO standards and drives continuous improvement.

Organizations should prioritize auditor independence, invest in training, develop detailed audit plans, foster clear communication, and allocate sufficient resources. By doing so, they can enhance the value of internal audits and leverage them as a tool for sustained success and quality improvement.
