Understanding the OEE Loss Tree to Improve Overall Equipment Efficiency

In the industrial sector, production line performance is a critical lever for plant competitiveness. The Loss Tree OEE (Overall Equipment Effectiveness) concept helps to identify and categorize losses that affect overall equipment efficiency. However, many plants struggle to structure this data correctly, which limits their ability to accurately identify sources of waste and inefficiency. Ignoring these elements can lead to significant financial losses and reduced competitiveness in the marketplace.

The main causes of efficiency losses are often unplanned interruptions, excessively long adjustment cycles and non-conforming product quality. These factors have a direct impact on productivity and increase production costs. A low OEE rate can be the result of under-optimized machines, poorly calibrated processes or unresolved bottlenecks. Every minute of downtime or every defect detected represents a lost opportunity to increase output or maintain the quality expected by customers.

To solve these problems, organizations need to focus on continuous improvement by implementing performance management tools such as TeepTrak. By digitizing real-time performance monitoring and equipping themselves with analytical dashboards, companies can better understand the distribution of losses thanks to the Loss Tree OEE. Adopting solutions such as TeepTrak’s to digitalize your production improves visibility across all production lines. Analysis tools enable you to accurately track production stoppages and anticipate potential drifts.

A concrete example of the application of Loss Tree OEE can be seen in an automotive assembly plant. Thanks to the integration of TeepTrak, the plant was able to draw up a detailed map of losses due to unplanned stoppages and quality problems. By analyzing this data, the plant was able to identify a specific bottleneck on the paint line, linked to sub-optimal nozzle cleaning cycles. Thanks to the corrective actions initiated, the line’s overall OEE increased by 12%, from 70% to 82%, illustrating a substantial improvement.

For industrial decision-makers, it is crucial to launch initiatives aimed at structuring a robust OEE project. Starting by measuring and tracking key performance indicators will help to better visualize where losses lie, and optimize processes accordingly. Adopting digital solutions for real-time monitoring, as proposed by TeepTrak, ensures greater rigor and responsiveness in steering operations. This approach not only reduces the costs associated with inefficiencies, but also guarantees greater customer satisfaction thanks to optimum production quality.
