From Juran's Quality Control Handbook.....

"Evolutionary operation (EVOP): This analytical approach is aimed at securing data from manufacturing operations (as distinguised from laboratory or pilot plant experiments). Successive lots are made under process conditions which vary from one lot to another. The EVOP method goes a stepfurther by deliberately creating some variation which will provide needed data without jeopardizing the product. Specialanalysis techniques then derive the relationships which form the basis of product improvement (See section 26 under Evolutionary Operation.)" Gosh, this stuff even SOUNDS

Please post new questions, etc. to the Elsmar Cove Forum.
