OEE Implementation Guide

An Industry White Paper From OMAC (The Organization For Machine Automation & Control)



This industry white paper describes Best Practices regarding the recommended method to implement OEE (Overall Equipment Effectiveness) for production lines in order to measure actual production against the industry standard target. The purpose of this guide is to help both OEMS and End Users with different experience levels understand how to effectively implement OEE to extract the most accurate and useful information in the most consistent, and easily repeatable manner. This document draws from best practices based on real world implementations from both equipment manufacturers and data collection/historian systems, all of whom are members of OMAC.

Executive Summary


The purpose of this document is to empower OEMs and End Users to understand the how to calculate OEE and how to effectively implement it across individual machines or production lines, typically during Site Acceptance Testing.

This document details what information is required for individual machines or workstations but does not recommend that the OEE calculations be performed by the individual equipment on a production line. This document lists the signal information that should be continually provided in order to allow the OEE calculations to be performed.


This document was created by the OMAC team to help both OEMs and End Users gain a better understanding of OEE, which is frequently used as part of Site Acceptance Testing (SAT). Due to the different potential ways that OEE can be calculated, this document was sourced to create a recommendation on what metrics to track and how to best track them and to identify areas where there may be deltas between how OEE is calculated.
