According to Dr Swyt, the National Center for Manufacturing Sciences' assessment of state-of-the-art conventional machining indicated that tolerances had decreased by a factor of five during the decade of the 1980s.
According to the account by Taguchi cited by Mr Swyt, "quality in the operation of an automobile door as perceived by customers correlates with the variations in, the force required to open the door.
