How do you calculate the overall equipment effectiveness of OEE?
In practice, OEE is calculated as:
- OEE = (Good Count × Ideal Cycle Time) / Planned Production Time.
- Availability = Run Time / Planned Production Time.
- Performance = (Ideal Cycle Time × Total Count) / Run Time.
- Quality = Good Count / Total Count.
- OEE = Availability × Performance × Quality.
What is meant by overall equipment effectiveness?
Overall Equipment Effectiveness (OEE) is an industry standard, versatile measurement for production efficiency. It suits any industry or process. OEE is the result of three factors, Availability, Performance and Quality, which describe the six big losses. Together these factors form OEE = A x P x Q.
What are the 3 components of OEE?
The preferred OEE calculation is based on the three OEE Factors: Availability, Performance, and Quality. OEE is calculated by multiplying the three OEE factors: Availability, Performance, and Quality.
Why is overall equipment effectiveness OEE important?
OEE is one of the most important performance measurements in modern manufacturing facilities. By optimising OEE, you can increase capacity, reduce costs, improve quality, and/or increase efficiencies in your production lines.
Can OEE be more than 100%?
Is it possible for OEE or any of its underlying metrics to exceed 100%? No. An OEE score of 100% represents perfect production – manufacturing only good parts, as fast as possible, with no stop time.
How is OEE calculated with example?
The calculation of the availability rate is:
- Availability = B / A x 100.
- = 77.7%
- Performance = D / C x 100.
- = 86.1%
- Quality = F / E x 100.
- = 97.8%
- OEE = 65.4%
What is OEE dashboard?
An OEE Dashboard is a production visibility tool that displays real-time OEE scores in a public, easy-to-understand visual format.
What are the factors affecting equipment effectiveness?
Based on analysis, the factors which affect equipment productivity are late inspection, condition of sites, operators efficiency and availability of skilled operators.

What is OEE and why is it important?
OEE (Overall Equipment Effectiveness) is the gold standard for measuring manufacturing productivity. Simply put – it identifies the percentage of manufacturing time that is truly productive. An OEE score of 100% means you are manufacturing only Good Parts, as fast as possible, with no Stop Time.
What is the purpose of OEE indicator?
The primary purpose of OEE is to benchmark progress in improving manufacturing productivity (i.e., eliminating waste). TEEP (Total Effective Equipment Performance) measures the ratio of Fully Productive Time to All Time (24/7).
Does OEE include scrap?
OEE QUALITY Examples of things that create Quality Loss include scrap and parts that need rework. OEE Quality is similar to First Pass Yield, in that it defines Good Parts as parts that successfully pass through the manufacturing process the first time without needing any rework.
