This paper will provide an in depth discussion of the importance of understanding the measurement system in terms of accuracy, precision and discrimination. The need to identify the repeatability (precision) of a measurement system with respect to the particular product to be measured will be presented in context of wire and cable examples. A mathematical model will be provided that will develop a single metric (discrimination ratio) that will serve to identify if a particular measurement system is adequate for process improvement purposes or must be limited to a go/no go function. A second model will be offered that will provide an understanding of the actual amount of product variation (intraclass correlation coefficient) being experienced. This will be accomplished by mathematically separating the amount of measurement system variation from the total variation of measurement observations. The paper will deal with all of the above topics of non-destruct as well as destruct measurement systems.
