performance indicator

A measurable goal used to determine system performance and level of service provided. Examples of performance indicators include the number of stoppages per 100 miles of pipe per year and the number of lost time accidents per year—measurements of how well a utility is doing rather than how much a utility is doing. Also see production indicator.
