Alcance
ISO 18828-4:2018 specifies a set of key performance indicators in production planning, which allow comparison and monitoring of the production planning process in a standardized framework. As a first step, the utilization of the KPIs is elaborated in order to organize the indicators in a multi-level system taking different ranges of the planning process into account. This development of a multi-level system represents the core of ISO 18828-4:2018. The scope of the planning processes discussed in ISO 18828-4:2018 is limited to production planning for products in series production. Only tasks carried out within the production planning process are considered in this approach. All key indicators presented are recommendations and can also be used in accordance with the general validity of the reference process from ISO 18828‑2 and relate to the content described in ISO 18828-4:2018.
