Value Stream Mapping (VSM), an illustrated method that describes the flow of raw materials and the values that customers provide, shows the main stages of the operation process, besides data related to the material flow, quality, order fulfillment time, and production rhythm. This research focuses on building VSM for the computer desk production process at School Equipment Workshop, College of Engineering Technology, Can Tho University. In this study, the order date has been collected to select the product family to streamline the production process, working time, processing time for each stage, inventory quantity, and time of inventory usage. The current VSM determines wastes and bottlenecks in the production process. Using Lean tools (i.e., 5S, balancing line, traction production, inventory shelf, Kanban, and FIFO cards) will be employed for continuous improvement and establishing future VSM based on these suggested improvements. Finally, the Arena model simulates the production process before and after improvements, considers workers' performance, and identifies bottlenecks. The study will clearly show optimal results after using lean tools and simulating the computer desk production process of the factory. The findings showed that production time declined by 12.6 hours (improved by nearly 25%), while the Process Cycle Efficiency increased by 1.36% (approximately 35% improvement). Finished goods and WIP time, which account for approximately 50% of inventory time, have dramatically dropped by 41%.
