How do ISO 22301, ISO 19011 and ISO 17021-1 relate in an audit?

ISO 22301 defines the requirements of the BCMS being audited. ISO 19011 sets the audit methodology. ISO 17021-1 governs the conduct of certification bodies. All three apply in every professional BCMS audit.

ISO 22301 sets what the auditor audits: the requirements of a business continuity management system, its controls, its evidence and its links to governance. Without command of ISO 22301, an auditor cannot formulate substantive findings and can only verify that documents exist.

ISO 19011 sets how the audit is done: principles, management of the audit programme, planning, execution, auditor competence and professional conduct. ISO 17021-1, in turn, governs certification bodies and establishes the expectations of impartiality and rigour placed on external auditors.

The course integrates all three so that the auditor operates with judgement across internal, supplier and certification audits. In practice ISO 19011 provides the method, ISO 22301 provides the scope, and ISO 17021-1 provides the certification credibility — a competent Lead Auditor knows when to apply each.
