According to ISO 19011:2018, Clause 6.4.2, guides may be appointed by the auditee to assist the audit team in identifying individuals to be interviewed, providing access to sites, and ensuring communication. Not every auditor must have an individual guide, and the decision is typically made collaboratively between the audit team leader and the auditee based on the audit scope, complexity, and logistics.

The scenario describes that the decision was made in mutual agreement with the audit team leader, which complies with best practices.
