OEE (Overall Equipment Effectiveness) is a core metric of TPM that identifies the percentage of planned production time that a manufacturing plant is truly productive. OEE is calculated using three measures: Availability, Performance, and Quality.
An OEE value of 100% indicates that the operation is producing perfect products, with no waste (100% Quality), as fast as possible (100% Performance) and without any downtime (100% Availability).
Your Guide to Understanding and Calculating OEE

The OEE Whitepaper includes detailed definitions of OEE, formula cheat sheets, and more.
The generic OEE calculation is simple:
OEE = Quality x Performance x Availability
This will provide you with an overview of your production performance as a percentage, and can then be used as a baseline for future improvements.
There are also a variety of other OEE models commonly used. Depending on your production site and the goods you're producing, these may provide an OEE score that better represents your performance.

Benefits of Measuring OEE
Provide a single figure that can be understood by everyone – from management to operators.
Report on Asset Utilization
Ensure your equipment is being used effectively by monitoring performance, up time, and yield.

Automating OEE Measurement with OFS
Manually calculating OEE can be tedious, time-consuming, and is prone to human error. OFS makes it easier than ever to keep track of your production performance by automating data collection and generating pre-built reports and dashboards that monitor your performance in real-time.
To request a demo of the OFS software solution, or to learn more about how other leading manufacturers are using OFS to drive efficiency improvements, click below.
We’ve seen results of improving OEE from under 50% to around 85% over a 4 month period. OFS helped bring to life where the key issues are on this line and we were able to focus and fix.
