In-depth Use Case / Real-world Example

Percentage of Unplanned Downtime tracks the proportion of downtime caused by unforeseen issues like equipment failure or material shortages. For example, if 5 hours of downtime occur unexpectedly out of 50 total hours, the percentage of unplanned downtime is 10%. Minimizing unplanned downtime is crucial for improving overall equipment effectiveness (OEE) and increasing production capacity. Proactive maintenance and better forecasting can help reduce unplanned downtime.
