Organizations should footnote the specific critical equipment described, as well as all assumptions used. See usage guidance for further information.
This metric should be the ratio of days when the machine or facility actually was available over the expected availability. Expected availability should not be reduced for times in which the equipment or facility was broken, not in use due to electricity shortages, etc.
This metric should be reported on separately for each equipment and facility.
A common usage example for organizations operating in the health sector could be patient bed occupancy rates.
