Which type of review can often used as a secondary method to support other forms of information collection methods?

A documentary review is a type of review that involves examining documents, records, or other

forms of evidence related to the audit criteria and objectives. It can often be used as a secondary

method to support other forms of information collection methods, such as interviews, observations,

or sampling. A documentary review can help to verify the existence, implementation, and

effectiveness of the audited processes, activities, or controls. It can also provide useful information

about the context, scope, and objectives of the audit, as well as the roles and responsibilities of the

auditees and other relevant parties. Reference: ISO 22301 Auditing eBook, page 611; ISO
