การลดระยะเวลาการรอคอยในการปล่อยใบสั่งปล่อยสินค้า

Abstract

The objective of this engineering project is to reduce the time spent on releasing delivery order (D/O). The researcher has found that the problems occurred both inside and outside the organization. Internally, it is shown that the staff at the counter were not aware of the responsibilities of each member. Moreover, they did not sort their working files. Externally, the problem was that the customers did not recognize the procedures of document preparation when receiving the D/O. Also, they hired an agent who had no knowledge regarding receiving the D/O, which was more time-consuming. Therefore, this project has proposed efficient guidelines to deal with the issue by using four tools: cause & effect diagram, why-why analysis, flow process chart and PDCA to control the operation. In order to check and compare each step before and after the solutions, the researcher conducted a comprehensive guides on receiving D/O for customers and on staff members’ scope of work for the staff. It is found that after implementing the guidelines, the staff and that customers can reduce the time of releasing D/O by 28%. Furthermore, the customers and new staff members can simply understand and execute each procedure.
