ISO 19011:2018(en) Guidelines for auditing management systems defines "Audit" as:

Audit

Systematic, independent and documented process for obtaining objective evidence (3.8) and evaluating it objectively to determine the extent to which the audit criteria are fulfilled.

See terms and definitions for "Review" for the relevant standards e.g., ISO 9000:2015(en) Quality management systems — Fundamentals and vocabulary.

Review

EXAMPLE:

Management review , design and development (3.4.8) review , review of customer (3.2.4)requirements (3.6.4), review of corrective action (3.12.2) and peer review .

Note 1 to entry: Review can also include the determination of efficiency (3.7.10).
