In this study, we focus on the modeling of the judicial system through a suite of System Dynamics. More specifically, employing a participatory modeling approach (GMB – Group Model Building) based on the System Thinking methodology, we have developed Causal Loop Diagrams, which we have then transformed into quantitative models through the modeling and simulation methodology known as System dynamics. The System Dynamics approach allows the development of context and scenario analysis aimed at identifying bottlenecks and high-leverage strategies for improving the judicial system’s performance. We carried out 50 interviews and 200 hours of participatory observation in shadowing the human resources working within the Italian courts, and the present paper relates to our main findings.
