The figure is an example of an ABC Inventory Valuation Analysis.  It is a little like drilling for oil, in that the analysis helps reveal where the pockets of excess inventory investment have accumulated.  The analysis considers A, B, and C SKUs; purchased domestically and internationally; cross-docked or moved through the warehouse; and located in-transit, in the warehouse, or in a retail store location.  This analysis helps reveal the most significant opportunities for reducing inventory investments.
