Abstract
The current study aims at evaluating the reorganization of work processes on the basis of studies of three assembly lines in a well known component manufacture of the German automotive industry. It is of particular interest to evaluate the impact of the introduction of Chaku-Chaku assembly lines on the production goals, distribution of activities during one typical work day and psychosocial characteristics of the work environment. Findings indicate that the Chaku-Chaku assembly lines could represent a successful production strategy in order to enhance the output levels of work systems. However, the data show that interviewed assembly workers have spent more time on value added activities than before. The intensive perception of the time spent on main work activities (direct value added activities) and a simultaneous decrease of available discretionary time between work tasks seem to be related to the low level of the reported psychosocial work characteristics.
