Level of Joint Optimization

Abstract

The macroergonomic construct of joint optimization was operationally defined as time allotment to the personnel and technological subsystems in a laboratory quality inspection experiment. Individual and group performance as well as perceived level of joint optimization were measured for each treatment condition. The experiment was organized as a one-factor between subjects design with six levels: 30%, 40%, 50%, 60%, 70% and 80% allotted to the technological subsystem. While there were no significant differences in individual performance due to the amount of time allotted to tasks in the technical or social subsystems, differences did occur at the group performance level. Overall, the results of the study are encouraging and suggest there may be a cause and effect relationship between time allotment and level of joint optimization and performance in the technical subsystem.
