Cycle Counting (CC) and yearly Physical Inventory (PI) are the best methods for accurate inventory Management. CC can detect an immediate discrepancy, however the reason for the discrepancy should be followed up with an RCCA (Root Cause & Corrective Action) and reported to the Supply Chain Leader. If the RCCA doesn't happen, the issue may repeat itself. A yearly PI justifies how well the Warehouse is managing the inventory, but what is missed sometime is the Finance audited of the PI to ensure accuracy of the counts. All PI discrepancies should have a RCCA too. Only after the RCCA is reviewed by Supply Chain Leader, should the inventory be adjusted.
