Overall equipment effectiveness (OEE) is a mathematical system developed to accurately measure the performance of a company’s manufacturing operations, processes, and overall productivity. This metric is expressed as a percentage; OEE shows how efficient a production facility is. It can be compared to a company’s past OEEs to gauge improvements or losses, and to predict future productivity.
What are Overall Equipment Effectiveness Metrics used for?
OEE is a decent gauge of a machine’s or a system’s productivity level. It can also glean insights into the behaviors and effectiveness levels of the workers who maintain and operate the system.
For example, a lousy maintenance technician might fix problems, but they won’t prevent them from occurring again in the future. A good maintenance technician will complete regular inspections to find and fix problems before they occur. OEE also offers a method of gauging the success of facilities, staff, systems, and processes.
Calculating Overall Equipment Effectiveness
The calculation of overall equipment effectiveness uses three metrics:
- Availability = Production Time / Loading Time
- Performance = Actual Output / Production Time
- Quality = Good Output / Actual Output
All three of these metrics are expressed as percentages.
Using these three metrics gives business owners and facility managers a real-world view of their facilities’, employees’, and machinery’s current and former productivity and overall cost-to-benefit ratio.
