Visit four retail stores with another classmate. In each store, identify whether the store uses a bar-coding system to help manage its inventory. Try to find at least one store that does not use bar-coding. If a store does not use bar-coding, ask the store's manager or clerk whether he or she knows which type of inventory method the store employs. Create a table that shows columns for the name of store visited, type of merchandise sold, use or nonuse of bar-coding, and the inventory method used if bar-coding is not employed. You might also inquire as to what the store's inventory turnover is and how often physical inventory is taken.
