According to the ISO 19011:2018 standard, which provides guidelines for auditing management systems, the team leader of an audit team should be an auditor who has demonstrated the competence to manage an audit of the relevant management system scheme. This means that the team leader should have the appropriate knowledge, skills, and experience to plan, conduct, report, and follow-up an audit of the specific management system, such as ISO 9001 for quality management systems. The other options are false because: B. An audit team can include non-qualified auditors, but only as observers or trainees who do not contribute to the audit findings or conclusions. C. A technical expert can assist a qualified auditor on an audit team, but cannot replace them, as a technical expert does not have the competence to perform audits. D. Audits leading to auditor qualification are not undertaken annually, but rather as part of a certification process that involves meeting certain criteria, such as education, work experience, audit experience, and examination.
