ABC analysis - Answers- Has been developed to determine which inventory items
should receive the highest level of control. By multiplying the dollar value of each item
by its annual usage, a dollar usage value can be obtained. Dollar usage follows the
Pareto Principle in that frequently, only 20% of all the items account for 80% of the total
dollar usage, while the remaining items frequently account for only 20% of the dollar
usage. This principle leads to the _____ classification, which is based on focusing
efforts where the payoff is highest
