While industrial and organizational psychologists have been concerned about the national problem of increasing productivity, most research has focused on simple jobs with the individual as the unit of analysis. Most jobs are more complex and, because of the interdependencies in the work, require group-level interventions and more complex measures of performance or productivity. This research presents a new method of measuring productivity, the Productivity Measurement and Enhancement System (ProMES), and uses measures from this approach as a foundation for group-based feedback, goal setting, and incentives. The experimental design consisted of a baseline period of 8 to 9 months, followed by a 5-month period of feedback based on the ProMES. Goal setting was then added to feedback for 5 months. Finally, incentives in the form of time off from work were added to feedback and goal setting for another 5 months. Results indicated that group-level feedback increased productivity an average of 50% over baseline, group goal setting increased productivity 75% over baseline, and group incentives increased productivity 76% over baseline. Control group data showed no or only a slight increase in productivity over the same period, and level of personnel either stayed the same or decreased. In addition, work attitudes such as job satisfaction, turnover intentions, and morale were as good or better following the interventions. Issues pertaining to group-based interventions are discussed.
