Abstract
This paper describes the result of an experimental study on a comparison of a new designed job enlargement system with a conventional conveyer system in a practical workshop, where the same workers were used as the common subjects working in both systems. It became clear through the experiment that both the productivity and steady CFF level were higher in the job enlargement system than that of the another. It was confimed that the workers behave more freely during working time in the new system than in the another one. Under the conditions mentioned above, it is clear from this study that the job enlargement system is relatively superior to the conveyer system in tems of the work-load and productivity.
