Because the inventory manager does not carry out inventory audits or counting, she is unaware of the inventory shrinkage due to theft and places her orders based on the on-hand inventory value she calculates. She is also unable to observe actual demand and only observes sales. Modify the Excel file to calculate how the physical on-hand inventory of the product varies in over the 15 periods and describe what happens.
