Which category of OEE accounts for equipment that is available but not operating at full capacity?

The correct choice is Availability. This category specifically measures the percentage of time that equipment is operational compared to the total time it is scheduled to operate. It takes into account any downtime due to maintenance, breakdowns, or any other factors that prevent the equipment from running, even if it is physically available.

Performance focuses on how well the equipment operates when it is running, assessing whether it produces at its optimal speed and efficiency. Quality deals with the production of defect-free products, measuring the percentage of good output versus the total output produced.

In contrast, Availability directly addresses the situation where equipment might be available but not currently operating at full capacity, encompassing aspects that impact its readiness to perform. This distinction helps organizations identify and minimize downtime, thereby improving overall equipment effectiveness (OEE).
