Unlocking Manufacturing Excellence: The Power of OEE

Unlocking Manufacturing Excellence: The Power of OEE

If you’ve worked in manufacturing for any length of time, then you’re probably familiar with the term “Overall Equipment Effectiveness,” or OEE. OEE is a metric that measures the efficiency of your equipment and operations. It’s an important indicator of how efficient your plant is—and it can also be used to help identify opportunities for improvement and drive change.

What is OEE?

OEE is a measurement of the effectiveness of your business. It’s used to identify problems and opportunities, so it’s important to understand what OEE means, how it can be calculated and how you can use this information to improve your business performance.

OEE stands for Overall Equipment Effectiveness, which is defined as: “The ratio between equipment availability (A), Quality (Q) and Performance (P). It represents an overall indicator of equipment efficiency.”

In other words, OEE is an indicator of how efficient your machinery is. It can be calculated by dividing the number of hours that a machine or piece of equipment is running (availability) by the total cost per hour to run it (performance).

Measuring OEE in a manufacturing environment

To understand OEE, you first need to know what it stands for: Overall Equipment Effectiveness. OEE is an important metric that helps companies measure the efficiency of their manufacturing processes. It can be calculated by dividing 3 things: Availability (A), Performance (P), and Quality (Q).

  • Availability represents how often your equipment is running as expected. If a machine is down for maintenance or breaks down unexpectedly, this will reduce its availability score.
  • Performance measures how well your equipment performs when it’s up and running–so if there are any quality issues with the product being produced on your machines, then that will affect their performance scores negatively as well. 
  • Quality is determined by measuring defects in the products being produced by each machine; if too many defects are found during inspection, then this will also lower its overall quality rating. 

You can also combine these three factors into one formula: OEE = Availability x Performance x Quality So if your availability is 90%, your performance is 85%, and your quality is 95%, then your OEE will be 83%.

Why should you measure OEE?

OEE is a measure of overall equipment effectiveness. It’s a way to gauge how efficiently you’re using your machines, the quality of their output and whether they’re profitable.

For example: if you have an OEE score of 80%, that means 20% of time spent on equipment is wasted–meaning you could be producing more with less effort if only those pesky inefficiencies were ironed out!

OEE isn’t just a number, it’s also a way to measure your business. It helps you understand how much time is spent on equipment, the quality of the output and how profitable those machines are. If you want to grow your business, then improving OEE is one of the best ways to get there.

How can you improve your OEE?

You can use OEE software to help you identify areas where your processes are inefficient, or where equipment is performing poorly. You can then use this information to improve your processes and equipment, which will lead to improved OEE.

There are several ways that you can improve OEE:

  • Use OEE software to track the efficiency of individual machines, allowing you to see when they’re running well or if they need maintenance. This information allows you to schedule repairs and maintenance at appropriate times–saving money by avoiding unnecessary downtime.
  • Use OEE data from previous months as a baseline for future improvements; this will help ensure that any changes made are actually improving productivity instead of making things worse!

Use OEE software

Professional OEE monitoring and reporting software can help you to improve your OEE by providing real-time data and analytics. As a result, you’ll be able to identify opportunities for improvement in your manufacturing process before they become problems.

This is especially important when it comes to labor costs, which often account for up to 80% of an organization’s total operating expenses. When workers are idle or working inefficiently due to bad processes or poor communication between departments, it’s easy for these costs to spiral out of control–especially if an employee needs training or equipment upgrades before being able to perform their job effectively (or if they’re simply not qualified).

OEE software collects data from multiple sources across the factory floor and uses algorithms that combine this information into metrics such as Availability, Performance Efficiency (or Quality), and Capacity Utilization Rate (or Production). The resulting reports give management insight into how well each individual machine is performing relative its peers based on things like utilization rates; whether there are any bottlenecks slowing down production; etc.

Use OEE to drive efficiency improvement

Your OEE is a reflection of the efficiency of your manufacturing processes. As such, it’s the best way to assess whether your business is running at peak performance and can help you identify areas where improvement may be needed.

Using OEE as a measure for improvement can be tricky because many factors contribute to its calculation–but there are some simple steps you can take to improve the results:

  • Focus on the key drivers of OEE (e.g., quality) and work toward improving those first before moving on to other areas that might affect overall performance but aren’t necessarily mission-critical for success in manufacturing operations.
  • Improve these key components individually by using tools like control charts or Pareto analysis (a method used for identifying significant factors that impact outcomes).
  • Once you have identified the key factors, it’s time to find ways to improve them. For example, if quality is a key driver of OEE, then focus on reducing defects and improving yield. Use tools like Six Sigma statistical analysis or design of experiments (DOE) to identify root causes of problems and implement solutions that will prevent future occurrences.


OEE is a powerful tool for driving efficiency improvement in your manufacturing environment. It allows you to measure the efficiency of your processes, identify areas that need improvement and track progress towards achieving your goals. OEE software can help you do all this with ease and at no cost!
