Proxy indicator

DEFINITION: A variable used to stand in for one that is difficult to measure directly.

COMMENT: Cost, complexity and/or the timeliness of data collection may prevent a result from being measured directly. In this case, proxy indicators may reveal performance trends and make managers aware of potential problems or areas of success.
