8 technical questions about ISO 22301 Audit — Business Continuity Management System. Timelines, methodology, deliverables and assessment criteria.
ISO 22301 is the international standard for business continuity management systems. It establishes requirements for planning, implementing, and maintaining an organization's ability to continue operating during disruptive incidents.
Organizations whose operational disruption generates critical impact: financial entities, essential service providers, global supply chains, data centers, and critical infrastructure operators.
Between 5 and 15 business days depending on the number of critical processes and the complexity of interdependencies between areas. Multi-site organizations require an expanded scope.
The business impact analysis (BIA), continuity risk assessment, documented continuity plans, and exercise and test results are evaluated. All in accordance with the ISO 19011 audit framework.
Continuity system gap report, BIA maturity assessment, review of recovery time objectives (RTO/RPO), and recommendations for the exercise program.
ISO 22301 complements ISO 27001 in the availability and resilience dimension. It articulates with ISO 31000 for risk management and ISO 27031 for ICT service recovery.
Frequent findings include outdated BIA, continuity plans not tested in the last 12 months, absence of defined RTO/RPO for critical processes, and lack of documented crisis communication.
Conduct an updated BIA, identify critical processes with their dependencies, document RTO and RPO per service, and execute at least one tabletop exercise prior to the assessment.
