EVOP

EVOP or Evolutionary Operations is a manufacturing process-optimization technique developed in the 1950s by George E. P. Box.

In EVOP experimental designs and improvements are introduced, while an ongoing full-scale manufacturing process continues to produce satisfactory results. The idea is that process improvement should not interrupt production.
