Editing Engineering tolerance (section)

==An alternative view of tolerances==
[[Genichi Taguchi]] and others have suggested that traditional two-sided tolerancing is analogous to "goal posts" in a [[Football (disambiguation)|football game]]: It implies that all data within those tolerances are equally acceptable.  The alternative is that the best product has a measurement which is precisely on target. There is an increasing loss which is a function of the deviation or variability from the target value of any design parameter. The greater the deviation from target, the greater is the loss. This is described as the [[Taguchi loss function]] or ''quality loss function'', and it is the key principle of an alternative system called ''inertial tolerancing''.
