Since the second edition of this document was published in 2011, a number of new management system standards have been published, many of which have a common structure, identical core requirements and common terms and core definitions. As a result, there is a need to consider a broader approach to management system auditing, as well as providing guidance that is more generic. Audit results can provide input to the analysis aspect of business planning, and can contribute to the identification of improvement needs and activities.
An audit can be conducted against a range of audit criteria, separately or in combination, including but not limited to:
— requirements defined in one or more management system standards;
— policies and requirements specified by relevant interested parties;
— statutory and regulatory requirements;
— one or more management system processes defined by the organization or other parties;
— management system plan(s) relating to the provision of specific outputs of a management system (e.g. quality plan, project plan).
This document provides guidance for all sizes and types of organizations and audits of varying scopes and scales, including those conducted by large audit teams, typically of larger organizations, and those by single auditors, whether in large or small organizations. This guidance should be adapted as appropriate to the scope, complexity and scale of the audit programme.
