PT. Indofood, in carrying out goods storage and retrieval activities, is carried out without a barcode and checklist system. Without this system causes high lead times, referring to the time recorded by the SAT system. This system is used by management to control the loading/unloading movement of the company. Longer times often result in inefficiency and wasted resources, and companies should review their processing times against benchmarks to identify ways to improve their lead times. The purpose of this study is to provide improvement efforts to overcome delivery errors on finished goods, reduce the lead time of the delivery process with the kanban system through the FIFO method, and compare the difference in the lead time of the delivery process before and after the procedure. The author's research process in carrying out research from planning to carrying out research at a specific time. The analysis carried out is to evaluate the results of the delivery system improvement, search for goods to be sent based on the delivery plan, and the amount of time required to make deliveries based on the lead time displayed via SAT. The results showed that the kanban checklist design using the FIFO method could reduce problems in shipping in and out of products in the warehouse by reducing recording errors and accelerating the recording process quickly, precisely and accurately. The product process flow based on the kanban checklist system makes it easier for operators in the implementation process from incoming products to outgoing products. Item data will be entered automatically into the existing computer Kanban checklist using the FIFO method. The type of barcode used is a barcode that can input data in the form of letters, numbers and symbols. The company needs this type because the data inputted in the barcode uses these three forms.
