Abstract : Stock-taking is generally carried out by most large manufacturing companies to calculate the suitability of the actual quantity of goods with the inventory system. A mismatch in stock-taking results between the actual quantity of goods and the data in the inventory system will certainly be very detrimental to the company. If the actual quantity of goods is more than the inventory system data, there will be a buildup of goods in the warehouse, and capital turnover will be disrupted. Otherwise, if the actual quantity of goods is less than the quantity in the inventory system, it will result in customer stop lines, and the company will get a penalty for reimbursement of stop line costs incurred to customers. This study aims to minimize the occurrence of mismatches between the actual quantity of goods and data in the inventory system when stock-taking is carried out. This research uses the Define, Measure, Analyze, Improve, Control (DMAIC) method to determine the cause of the mismatch between the actual quantity of goods and data in the inventory system during stock-taking. The data taken for this study were four months before the improvement, and three months after the improvement. The results of this study can reduce the mismatch between the actual quantity of items and the data in the inventory with an average per month from 964 pcs to 20 pcs per month.
