In equipment maintenance, what does "downtime" refer to?

In equipment maintenance, "downtime" specifically refers to the period when equipment is out of service for repairs or maintenance. This time is critical for assessing overall equipment effectiveness (OEE) since it directly impacts productivity and operational efficiency. During downtime, machinery may be undergoing necessary repairs, scheduled maintenance, or updates, which are essential to ensure that the equipment operates safely and at optimal performance levels once it is back in service. Understanding downtime is crucial for maintenance planning, as it helps organizations strategize ways to minimize production loss while ensuring equipment longevity and reliability.
