1. A method facilitating design, manufacturing, and other processes, the method comprising receiving a plurality of article characteristic values associated with a set of articles having a range of variation as to a plurality of article characteristics; selecting a predictor characteristic from the plurality of article characteristics; determining the regression model between the predictor characteristic and a first remaining article characteristic in the plurality of article characteristics, wherein the regression model includes lower and upper prediction boundaries receiving lower and upper specification limits for the predictor characteristic and the first remaining article characteristic; locating, relative to the regression model between the predictor characteristic and the first remaining article characteristic, the compliance area bounded by the upper and lower specification limits associated with the first remaining article characteristic and the predictor characteristic; locating the bounded regression area for the first remaining characteristic defined by the upper and lower prediction boundaries of the regression model and the upper and lower specification limits for the predictor characteristic; and identifying the relationship between the bounded regression area and the compliance area.
