This system, ABC (Activity Based Costing), used as identifying the transactions that a CE firm does and then designate indirect costs to product. It divides inventories as a 3 groups like A, B and C. First group is A, respects the highest value parts of inventory, in this case it written as Consolidated Electric stocks almost 20,000 items and buys its inventory from around 200 different manufacturers. The price of the items they purchase range from $0.01 to several hundred dollars. The top 2,000 items account for 50% of sales and the bottom 10,000 items account for 20% of the sales leaving the remaining 8,000 items accounting for 30% of the sales. That is to say, according to ABC analysis group A would include the top 2,000 items which accounts for fifty per cent of total sales. Then we made group B to second big sale which is bottom 10,000 items that accounts for twenty per cent. Finally the part C would remain 8,000 items so we clearly identified 3 groups as what ABC analysis needs that are why we decided to use ABC analysis for Consolidated Electric.
