Experience has shown that percentage non-defective, the ratio of perfect parts to the total parts, while useful for certain classes of investigation, is not a very satisfactory yardstick for measuring quality of complex products. This factor fails to take into account two important things: (1) Defects of different kinds are not equally serious. (2) Defects of the same kind vary in seriousness according to the degree of departure from specified limits. Thus a failure to meet a major requirement should have greater weight than a failure to meet a minor one and in like manner the degree of imperfection of a given kind should be taken into Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original American Telephone and Telegraph Company.
