Additional guidance for auditors planning and conducting audits

A.2 Process approach to auditing

The use of a “process approach” is a requirement for all ISO management system standards in accordance with ISO/IEC Directives, Part 1, Annex SL. Auditors should understand that auditing a management system is auditing an organization’s processes and their interactions in relation to one or more management system standard(s). Consistent and predictable results are achieved more effectively and efficiently when activities are understood and managed as interrelated processes that function as a coherent system.
