EVOP: An Underused Method

摘要

EVOP? An acronym for a new zero defects automotive program called "every vehicle operates perfectly"? No. "Each variable obfuscates production"? No. Well, then what is it? Evolutionary operation (EVOP) is a technique for process improvement based on the principle that processes generate products or services together with data useful for providing guidance for improvement. Recognizing that it is highly inefficient and wasteful to ignore these data, George E.P. Box devised a plan to put them to use and published it with crystal clarity in 1957. He dubbed it "evolutionary operation" because of its analogy with genetic evolutionary processes whereby the drive to survive through mutations encourages improvements in the physical characteristics of organisms.
