Incorporating Use History in Information System Remodularization

Current IS system remodularization approaches have mainly focused on source codes but insufficiently considered users. To mitigate this problem, we integrate the concept of use history and design structure matrix to develop a user-centered system remodularization approach (UCSRA-DSM) that can optimize system structure and improve user experience. In this article, we demonstrate the proposed UCSRA-DSM by empirically analyzing an enterprise information system of a large shipbuilding manufacturer in China. Different alternative DSMs are employed to evaluate our UCSRA-DSM, and a summative evaluation indicates the effectiveness of the UCSRA-DSM in improving user experience. This research has important implications for system remodularization and provides guidance for IS management.
