In the context of ISO standards, what is the role of the internal auditor?

The role of the internal auditor within the context of ISO standards primarily revolves around conducting audits and recommending improvements. This function is crucial for ensuring that the quality management system (QMS) adheres to both the established standards and the organization's own requirements.

Internal auditors systematically review processes and practices to evaluate their effectiveness and compliance. Through this process, they identify areas where improvements can be made, whether to enhance efficiency, address potential non-conformities, or ensure that the QMS is continually evolving to meet organizational goals and stakeholder expectations. The insights gained from these audits inform management decisions and help drive strategic improvements across the organization.

The other options do not capture the essence of the internal auditor's specific role as defined by the ISO standards. Managing all company departments is a broader leadership function, while handling customer complaints and writing company policies are tasks that typically fall under different roles within the organization. The primary function of the internal auditor is distinctly focused on assessment, compliance, and continuous improvement recommendations within the quality management framework.
