The deliverable is a single Excel workbook with a clearly labeled, easy-to-use Manager's Page. The warehouse manager will want to select any year's historical demand data or to clear the data and enter a new year's worth of demand values on the Manger sheet. In addition, the manager will want to specify key policy parameters (reorder point and order quantity). Ensure the Manager worksheet contains no errors or messages when data is cleared or changed. The Manager page should be professionally formatted and include an appropriate logo (image of your choice) and a descriptive project title
