ISO 19011:2002提供了关于审核原则、管理审核计划、进行质量管理体系审核和环境管理体系审核的指南，以及关于质量和环境管理体系审核员能力的指南。 它适用于所有需要对质量和/或环境管理体系进行内部或外部审核或管理审核计划的组织。 原则上可以将ISO 19011应用于其他类型的审计，前提是特别考虑确定审计团队成员在此类情况下所需的能力。

ISO 19011:2002 provides guidance on the principles of auditing, managing audit programmes, conducting quality management system audits and environmental management system audits, as well as guidance on the competence of quality and environmental management system auditors. It is applicable to all organizations needing to conduct internal or external audits of quality and/or environmental management systems or to manage an audit programme. The application of ISO 19011 to other types of audits is possible in principle provided that special consideration is paid to identifying the competence needed by the audit team members in such cases.
