Global process effectiveness: when overall equipment effectiveness meets adherence to schedule

Abstract

In recent decades, research has been done to better assess the effectiveness and efficiency of a production process. Therefore, some methods like Overall Equipment Effectiveness (OEE) or Overall Line Effectiveness (OLE) were proposed, however, none of the analysed methods has been able to illustrate accurate results in terms of adherence to a production plan. The purpose of this article is to present a metric, Global Process Effectiveness (GPE), based on OEE, that assesses effectiveness based on OEE factors and the schedule-adherence of a process to a pre-defined production plan, regarding product variety and quantity. If this new performance indicator replaces OEE, it will add one more goal to OEE without increasing the number of key performance indicators used in a company, giving a valuable assessment to operations planning experts.
