This report describes the history, development and current practice of measuring operator performance in systems, in particular military aviation systems, with additional emphasis on measurement in air combat maneuvering ACM . The principal themes are that a Performance is used interchangeably with proficiency, and as such has acquired evaluative meanings about goodness or badness of individual capabilities. Performance measures thus require the same attention to measurement properties and validation as any other measures on individuals. b there are tendencies to substitute physical measures, which scale physical quantities or events, for behavioral measures, which are representative of how well an individual can perform a given task. Performance measures are behavioral measures, and acquire meaning through validation operations beyond those required for physical measurement. Not all the measures obtainable on individuals or systems are appropriately called performance measures. c Task performance must be viewed as a construct. Tasks are complex and multidimensional individual proficiency must be inferred from limited observables. For proposed measures, it is necessary to show that measures are reliable, that they tap the most important components of successful performance, and that they are credible as representatives of individual task proficiency. Evidence supporting these demonstrations is acquired through the process of construct validation.
