OEE Topics


Our goal is to help you master the art and science of OEE (Overall Equipment Effectiveness), along with the closely related topics of Six Big Losses and TEEP (Total Effective Equipment Performance).

Topics are organized into three areas:

UnderstandUnderstand how OEE and the Six Big Losses work together to create an information foundation that identifies all your equipment-based losses to productivity.
MeasureMeasure and calculate OEE with practical advice on how to measure OEE for your application, as well as how to extend OEE to measure utilization and capacity through TEEP.
ImproveLearn a simple yet very effective OEE improvement methodology as well as insights as to what world-class OEE really means and insights on how you can leverage the Six Big Losses in your improvement program.

If you have any questions, we encourage you to contact us. We enjoy helping others – and your questions help us to continually improve this site.


Measuring OEE is a manufacturing best practice and includes Availability, Performance, and Quality scores

What is OEE?

A Gentle Introduction

The basics of OEE as presented on our home page. The perfect place to start.

> Explore What is OEE?

OEE includes three underlying factors: Availability, Performance, and Quality

OEE Factors

Availability, Performance, and Quality

A deep dive into the three OEE Factors: Availability, Performance, and Quality. Also introduces the corresponding losses, an understanding of which is critical to improving manufacturing productivity.

OEE Loss factors (Availability, Performance, and Quality) align to the Six Big Losses

Six Big Losses

A Foundation for Action

The Six Big Losses extend the three OEE losses to a larger and more actionable set of losses that are universal to virtually all discrete manufacturing operations. Each OEE loss aligns to two Six Big Losses and this page covers them all.

Calculate Overall Equipment Effectiveness by multiplying Availability, Performance, and Quality

Calculate OEE

Calculate OEE and the Underlying Factors

Learn the simplest OEE calculation (calculating just OEE) and the preferred OEE calculation (also calculating Availability, Performance, and Quality). Includes a complete worked example for the preferred calculation.

Step by step guide to measuring OEE with downloadable forms

Implement OEE

A Step-by-Step Guide to Measuring OEE

Practical tips and guidance to help you start measuring OEE in your application – quickly and effectively. Includes a PDF form that you can use to define key decisions for your OEE project.

Calculate TEEP (Total Effective Equipment Performance) by multiplying OEE by Utilization

Calculate TEEP

Unlock your Hidden Factory

Extend OEE to include a fourth factor: Utilization. Measure the capacity of your manufacturing operation with TEEP (Total Effective Equipment Performance) and unlock your hidden factory.

The XL Productivity Appliance™ measures OEE, Availability, Performance, and Quality for any manufacturing process

Visual OEE™

Drive Improvement on the Factory Floor

OEE is traditionally used as a “rearview mirror” metric. Enable your teams to become more proactive and to “win their shift” by measuring OEE and other KPIs in real-time, and by providing actionable feedback to the plant floor.

IDA (Information, Decision, Action) is a simple and effective process for improving productivity

Improve OEE

Transform Information into Results

Most companies place too much emphasis on results (the OEE Score) and too little emphasis on the factors that drive results: Information (OEE and Six Big Losses), Decisions (selecting which loss to address and how to address it), and Action (taking action to transform decisions into results). This is our favorite page – it’s a practical way to quickly get results.

85% OEE is often referred to as World-Class and is based on having 90% Availability, 95% Performance, and 99% Quality.

World-Class OEE

Set Meaningful Improvement Targets

World-class OEE is 85%. But what does that really mean? We’ll provide you with some context and some advice on how to set effective OEE targets.
