In this study, simulation models were developed to explore the effects of decentralization and interdependence on individuals working in research groups. We conducted the study by simulating clinical health-services research with large repositories of data. First, we modeled the standard research process, which we called "centralized activity," in which a highly-paid researcher accomplishes all tasks. In our second model, which we called "distributed activity," tasks were performed in parallel by specialized technicians at lower wage scales. The
