The purpose of the present study was to evaluate the effectiveness of a treatment package designed to improve and maintain set-up time in the extrusion department of a rubber manufacturing company. Subjects were exposed to various behavioral techniques including training and a feedback system in the form of both written and verbal supervisory comments with an emphasis placed on improving performance through use of videotaping. An attempt was made to maintain treatment gains by teaching supervisors how to give information concerning set-up performance to their employees. Results indicate that average weekly set-up times for each machine were significantly below baseline levels during the initial intervention and remained there throughout a 30 week period.
