Abstract
The human engineer, in his role as consultant to system design teams, is confronted with problems of measuring system performance in such a way that various elements of the system can be evaluated. The validity of such measurement techniques is often questioned but little data concerning the validation of such measurement techniques is available. Analysis of the problems involved in validating measures used in investigating man—machine systems suggest that the concepts of validity as adhered to in modern psychology might not be adequate for use by a human engineer confronted with a system in its development stage. The general approach to system evaluation and the concepts of validity are discussed in terms of the problems involved in determining the validity of measurement schemes commonly used in investigating the properties of a man—machine system.Keywords
