Abstract
This paper proposes and defends a thesis that global consistency of tolerances is achievable only by consistent use of statistics across specification, production, and inspection. It starts with a global view of variation in a product of an engineering enterprise, embodied in two major axioms: imprecision in manufacturing and uncertainty in measurements. It traces the successful evolution of statistical practices in production and inspection to deal with these variations. Finally, designer specified tolerances are brought into the global picture. Challenges that still lie ahead are summarized at the end.
“The conception of statistics as the study of variation is the natural outcome of viewing the subject as the study of populations; for a population of individuals in all respects identical is completely described by a description of any one individual, together with the number in the group. The populations which are the object of statistical study always display variation in one or more aspects.”
