The effect of various workspace configurations upon subject performance in removing and installing a component transformer using various screwdrivers was investigated. Subjects performed the task under 15 different workspace configurations and with the transformer placed in 3 different orientations with respect to the aperture. The different workspace configurations were achieved by combining 5 different aperture sizes 8, 10, 12, 14, and 16 inches and 3 different depths 6, 12, and 18 inches. Major results of this study within the range of conditions explored are a Work time decreased as aperture size increased. However, increasing aperture size above 10 to 12 inches did not appreciably shorten work time. b Increasing the depth of the component within the workspace resulted in longer work time. However, work time increased appreciably only at depths in excess of 12 inches. c Component orientation with respect to the aperture was an important determinant of performance. Work time increased as orientation changed from a straight-line access back to a right-angle access bottom and side.
