Summary Evolutionary Operation (EVOP) was introduced in this Journal in 1957 as a scheme for deliberately perturbing a manufacturing process to obtain information for subsequent product improvement. This article briefly reviews the concept and the process characteristics which are required for EVOP to be suitable. Next, the results of a recent survey concerning experiences with EVOP are presented. The survey indicates that EVOP is being used much less extensively than the respondents felt it should be. Some reasons given for this are reviewed. The way in which EVOP is being used also sometimes differs from the original EVOP concept and these differences are briefly indicated.
