For companies to sustain competitive advantages, it is required to redesign and improve business processes continuously by monitoring and analyzing process enactment results. Furthermore, organizational structures must be redesigned according to the changes in business processes. However, there are few scientific approaches to redesigning organizational structures. This paper presents a method for deriving and analyzing organizational relations from process models using social network analysis. Process models contain information on who performs which processes or activities, along with the assignment of organizational units such as departments and roles to related activities. To derive social relations among organizational units from process models, three types of metrics are formally defined: transfer of work metrics, subcontracting metrics, and cooperation metrics. By applying these metrics, various relations among organizational units can be derived and analyzed, which can suggest how organizational structure must be redesigned. To verify the method, the proposed metrics are applied to standard process models of the semiconductor and electronic industry in Korea
