OEE 6 Big losses -The Small Stop While it is SMALL, it can also be very BIG! 🤪 There we go again ...6 Big OEE losses #4-The Small StopBest way to understand Small stop is like traveling on a journey with the destinated place, along the way, you are estimating to reach the destination say in 1 hour, along the roadyou bumps into a traffic jam, road blockages, accidents etc. These are the small stops. In the production process, minor disruptions stop because of waiting for material to run, delay in getting the machine to run back after the disruption, equipment misallignment and jam up. These the are the common small stop that we were looking at.some advance processes has built in function that detect what is the stop like. That again can rely on the Stack lighting indicator or within the controller like PLC to detect the error code due to the disruption. Why is these small stops is important? as...

The Planned Stop - Six OEE Big Losses We can understand unplanned downtime, but why planned stop? 🤔In manufacturing, planned stops represent a major category of production losses and it is part of the OEE six big losses. These are intentional halts in machine operation—such as for model changes, tool changes, or scheduled maintenance—that can heavily impact OEE (Overall Equipment Effectiveness) if not managed properly.A key tool in managing and visualizing these stops is the Andon system—a real-time visual indicator (typically using stack lights with 3 or 4 colors) that communicates machine or process status directly from the production floor. A red or blue light, for instance, may signal a planned stop, alerting operators and maintenance teams in real time.While planned downtime is necessary, poor planning or execution can erode process availability and drag down your OEE score. That’s why tracking and optimizing these stops is vital.Common Causes of Planned Stops:* Model or Tool Changes – Switching between product variants requires precise...
