This study utilized an integrated approach combining the SCOR model and service blueprinting to conduct an in-depth analysis of the military logistics system. Based on this analysis, the current (As-Is) business processes were mapped, the current status and problems of the military logistics system were analyzed, and improved (To-Be) processes were proposed. First, to examine the current (As-Is) business processes of the military logistics system, interviews were conducted with practitioners responsible for relevant tasks, and related regulations, field manuals, and prior research findings were referenced. In particular, in analyzing the business processes, the SCOR model (horizontal processes) and service blueprinting (vertical structure) were utilized in an integrated manner, simultaneously incorporating the advantages of both techniques. Customer waiting points and fail points from the service blueprint were used to analyze the current status and problems, and improvement measures were derived at each stage based on the SCOR model's Best Practices, leading to the proposal of improved (To-Be) processes. This study will contribute to building a speed-oriented, user-centered military logistics system that aligns with future logistics support concepts.
