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

A documentary review (or documented information review) involves examining records, policies, and procedures. In management system auditing (per ISO 19011 and ISO 22301), it is often used as a secondary or foundational method to corroborate, support, or verify information collected through primary methods like personal interviews or direct observation. Reviewing documented information ensures that the BCMS aligns with standard requirements and provides a baseline of evidence before engaging in verbal questioning.

B. "Visionary review" is a fabricated term and not a recognized audit or data collection method in ISO standards.
C. "Personal review" is not a standard auditing term; audits utilize personal interviews or personnel observations, not personal reviews.
D. "Private review" is not a recognized methodological term for data collection in ISO auditing standards.
