We improve production efficiency!
What is OEE?
OEE (Overall Equipment Effectiveness) is a best-practice metric for monitoring and improving the efficiency of your manufacturing processes — such as machines, production lines, and assembly systems.
The definition of OEE is simple, practical, and powerful. it identifies the most common sources of productivity loss and groups them into three main categories: Availability, Performance, and Quality.
By doing so, it breaks down complex production data into clear and understandable metrics that provide a true measure of manufacturing productivity.It also forms the foundation for tools and methods that help improve production efficiency.
Availability measures productivity loss caused by downtime events planned or unplanned interruptions that stop production for a significant period of time.
Performance measures losses caused by slow cycles — factors that make a process run at zero or below its maximum possible speed.
Quality measures losses from defective parts — products that fail to meet quality requirements.
Together, these three factors combine into a single numerical value: OEE, a comprehensive metric that represents the overall efficiency and effectiveness of your production.
OEE provides a standardized method for measuring the effectiveness of Lean Manufacturing, TPM (Total Productive Maintenance), and other productivity improvement initiatives.
World-Class OEE
In mass-production factories, a world-class OEE is typically considered to be 85% or higher.
Studies show that the average OEE for mass-production factories is approximately 60%.
Clearly, most manufacturing plants have significant potential for improvement. Imagine what a 25% improvement (raising OEE from 60% to 85%) could do for your competitiveness and profitability.
Improving OEE
What is Visual OEE?
Visual OEE is a highly effective method for automating efficiency improvement in the factory.
At this stage, data related to OEE, productivity rates, production statistics, and more are visibly shared with employees. In fact, real-time production information is recorded in the software and displayed for
staff to see, ensuring full transparency and awareness across the factory floor. This method is an amazingly simple yet powerful solution for improving shop-floor productivity.
Its visual output is placed in the production hall, serving as an essential tool for Lean Manufacturing and real-time OEE monitoring
Delivering Actionable Information for Daily Decision-Making
If you’re tired of reviewing production data in outdated reports, the XL method offers a refreshing alternative!
It provides accurate, complete, and real-time data — all visible from anywhere As shown in the figure below, you can instantly view the overall factory status and a sample machine’s condition at a glance.
Ease of Implementation
Simply install one or two sensors at the end of the production line or at the bottleneck point, and enter the cycle time (the time required to complete one product) to get started. Optionally, you can also add your break schedule, Takt time, and shift times. This method offers over 100 different ways to visualize your production data. It’s really that simple!
