The object of research is focused on the process of sending PO and GRN documents to vendor in the Department of Transportation and Distribution. Data gatering was carried out through observation of object and interview with sources, namely parties related to the object of research. The data analysis method used was VSM analysis with the following steps: 1) making Current State Mapping; 2) calculation of Process Cycle Efficiency (PCE); 3) making Process Activity Mapping (PAM); and 4) making Future State Mapping.
