Question:Which of the following describes a joint audit?

A Joint Audit is when two or more audit organizations cooperate to audit the same auditee.

ISO 19011:2018 Clause 3.9 defines joint audit as: “An audit carried out by two or more auditing organizations cooperating to audit a single auditee.”

This is further echoed in ISO/IEC 42001:2023, which supports joint audits especially in multi-country and consortium environments (Clause 9.2.1 reference to audit scope management).
