The purpose of this study is to examine the role of Human Resources Management (HRM) practices in predicting firms’ operational performance as well as analyze the mediating effects of Just in Time (JIT) systems on the relationship between human resources management (HRM) practices and operational performance. In order to achieve this objective, the following analyses were used: multiple regression analysis was used to assess the direct impact of HRM practices on operational performance; hierarchical multiple regression analysis was used to assess the mediating effect of JIT on the relationship between HRM practices and operational performance. The results of data analyses show that the following HRM practices have a significant effect on the operational performance of organizations, whether JIT is a mediator or not: manufacturing and human resources fit team activities, and interaction facilitation. The other studied HRM practices were not found to have a significant effect on operational performance.
