ISO 22400定义了制造运营管理中使用的关键绩效指标（KPI）。 ISO 22400-2:2014规定了当前实践中选定的KPI数量。KPI通过其公式和相应元素、时间行为、单位/维度和其他特征来表示。ISO 22400-2:2014还指出了使用关键绩效指标的用户组及其对应的生产方法。 关于设备，ISO 22400-2:2014中的KPI与IEC 62264中规定的工作单元有关。

ISO 22400 defines key performance indicators (KPIs) used in manufacturing operations management. ISO 22400-2:2014 specifies a selected number of KPIs in current practice. The KPIs are presented by means of their formula and corresponding elements, their time behaviour, their unit/dimension and other characteristics. ISO 22400-2:2014 also indicates the user group where the KPIs are used, and the production methodology to which they correspond. With reference to equipment, the KPIs in ISO 22400-2:2014 relate to work units, as specified in IEC 62264.
