OEE, or Overall Equipment Effectiveness, is a standard metric used to measure manufacturing productivity. It evaluates how effectively a production process is utilized by breaking performance down into three key factors: Availability, Performance, and Quality. OEE helps identify production losses, track improvement over time, and benchmark operational efficiency across equipment and processes.
OEE Quality is one of the three core factors of Overall Equipment Effectiveness. It measures the percentage of good parts produced without defects, reflecting the impact of quality loss in the production process. Quality loss includes all parts that do not meet quality standards, such as scrap or rework. This metric is typically calculated by tracking the number of Reject Parts during production.
OEE Performance is one of the three key components of Overall Equipment Effectiveness. It measures how efficiently a machine or process runs compared to its maximum potential speed. Performance loss includes slow cycles and small stops. This metric is typically calculated by comparing the Actual Cycle Time to the Ideal Cycle Time, helping identify speed-related inefficiencies in production.
OEE Availability is one of the three core components of Overall Equipment Effectiveness. It measures the percentage of scheduled production time that is actually available for operation. Availability loss includes both unplanned stops (e.g., breakdowns) and planned stops (e.g., maintenance). Tracking these events is essential for improving machine uptime and overall productivity.
A structured problem-solving technique where a team repeatedly asks “Why?”—usually five times—until they reach the fundamental cause of an issue. The goal is to identify and address the root cause rather than treating surface-level symptoms.
A Lean method designed to maintain a clean, safe, and efficient workspace through five steps: - Sort: Remove unnecessary items - Set in Order: Organize tools and materials - Shine: Clean and inspect the area - Standardize: Create consistent practices - Sustain: Maintain and review improvements
The actual time required to produce one good part, excluding downtime. It is calculated as Run Time divided by Total Count and is used to measure OEE Performance.
The real-time rate at which products are manufactured during operational periods. It is calculated by dividing Total Count by Run Time and used as an alternative way to measure OEE Performance.
The complete 24/7 availability of time—used in TEEP (Total Effective Equipment Performance) to represent the total possible production time.
A TPM (Total Productive Maintenance) practice where operators are trained to perform basic maintenance tasks like cleaning, inspection, and lubrication to improve equipment reliability and reduce downtime.
