The factors are “management accounting practice has become distorted, direct labour has shrunk as a percentage of total cost for the majority of manufacturing companies, overhead costs are no longer a mere burden to be minimized, products have become more complex ,and the marketplace is more competitive”. It is because of all the reasons mentioned above, that companies needed a new costing system and hence the emergence of ABC.
