Machine hours or direct labor is not always used by companies as it may not be the appropriate cost driver for overhead in all cases, due to the complexity of the manufacturing processes. Some companies consider Activity Based Costing(ABC) as a better alternative. ABC uses multiple cost drivers rather than just one, to apply overhead to the various activities. Using ABC, a company can use the cost driver that has the best cause/effect relationship in its applied overhead costs.
