What Are Internal and External Audits?

Internal and external audits in ISO 22301 focus on evaluating the Business Continuity Management System (BCMS). Although both aim to achieve similar objectives, their approaches and responsibilities differ significantly.

Internal Audit ISO 22301

Internal audits are conducted by the organization’s own personnel or contracted auditors working from within. Their primary purpose is to identify areas for improvement before undergoing an external evaluation.

Key Characteristics of Internal Audits:

▪️Flexible scheduling.
▪️Initial assessment of internal processes and procedures.

Main Characteristics of External Audits:

▪️Impartial evaluation.
▪️Verification of compliance with standards.
▪️Detailed reports determining certification status.
