Acronym developed in the mid-20th century as manufacturing industries adopted statistical methods pioneered by Walter Shewhart and W. Edwards Deming. The term reflects the integration of statistics into industrial quality management.
SPC revolutionized manufacturing by shifting focus from inspecting finished products to preventing defects during production. The control charts used in SPC can detect process variations before they create defective products, saving companies millions by catching problems early.
