<![CDATA[Inventory Record Inaccuracy (IRI) remains a major challenge in warehouse management because discrepancies between physical inventory and system records can disrupt material availability, operational efficiency, and managerial decision-making. Although cycle counting is widely used to maintain inventory accuracy, periodic verification may delay the detection of discrepancies caused by frequent material receipt, issuance, and relocation activities. Existing studies have largely emphasized technological solutions, including barcode systems, Radio Frequency Identification (RFID), and digital inventory platforms, while event-based verification integrated into daily warehouse operations has received limited attention. This study proposes a Movement-Triggered Inventory Checking (MTIC) method as an event-based approach to support earlier detection of inventory record inaccuracies. Design Thinking was employed to identify operational problems, develop the method, design the verification workflow, and conduct a one-month pilot implementation. The pilot involved all inventory items experiencing receipt, issuance, or relocation transactions during the observation period, totaling 75 items recorded in the MySAP/ERP system. Physical quantities were compared with SAP inventory records. The implementation identified 25 inventory discrepancies (33.33%), while 50 items (66.67%) were consistent with system records. These findings indicate that inventory discrepancies remain substantial under conventional periodic verification and highlight the importance of validating physical inventory closer to material movement events. The proposed MTIC method provides a practical event-based verification framework linking physical checks directly to recorded material movements, supporting earlier discrepancy detection and improved transaction traceability in oil and gas warehouse operations and strengthens inventory control within routine warehouse activities.]]>
