Few specified tolerance limits for qualities of manufactured product are enforceable in the sense that 100 per cent conformity to them can be insured. The establishment of a design specification should therefore be viewed as a problem in economy that cannot be solved without consideration of the acceptance specification that is to be used in its enforcement. The solution of this problem in economy requires the point of view of statistical method and makes use of the tools of statistical quality control.
