The purpose of this study was to improve the efficiency of the operations involved in the finished product shipping process, using operational waste reduction techniques. The processes of the study consisted of the following parts: 1) Operation process study and information gathering using process flow charts. 2) Operation process analysis using 5W1H technique. 3) Operational activities"e waste analysis - according to the value stream principle. 4) Operational efficiency improvement implementation using ECRS principles. According to the study of shipping operation by using flow process chart, there are 14 activities. 5W1H technique was used to analyses the operational process and value stream principle has been used in the activities wastes analysis. The result found that there are 6 value-added activities, 4 non-value added activities, and 4 necessary non-value added activities. The ECRS principle has been used to improve the operational process. After the implementation, the work efficiency of the operators was increasing. The comparisons of the indicators are as follows: The prior 14 procedures are reduced by 4 procedures into 10 procedures (28.57 percent reduction), which resulted in the work interval being reduced 982 second from 2,749 second to 1,767 second (35.52 percent reduction).
