Lecture Management accounting: An Australian perspective - Chapter 8 introduce the activity-based costing. Learning objectives of chapter: Problems with conventional product costing systems, an activity-based costing model, initial decisions about ABC at Mason & Cox, using the ABC model for product costing at Mason & Cox, activity-based versus conventional product costs,. | Chapter 8 Activity-based costing Problems with conventional product costing systems General features of conventional systems Direct material and direct labour costs are traced to products Manufacturing overhead costs are allocated to products using a predetermined overhead rate Manufacturing overhead rate is calculated using some measure of production volume Non-manufacturing costs are not assigned to products continued Problems with conventional product costing systems Failure to adapt to the changing business environment Increasing levels of non-volume-driven manufacturing overhead costs Increasing proportion of non-manufacturing costs Causes of changes in costs Changing product structures Indicators of problems with a product costing system Product costing systems are likely to result in inaccurate product cost when Proportion of direct labour costs decrease Proportion of manufacturing overhead costs increase Proportion of manufacturing overhead costs, not related directly to . | Chapter 8 Activity-based costing Problems with conventional product costing systems General features of conventional systems Direct material and direct labour costs are traced to products Manufacturing overhead costs are allocated to products using a predetermined overhead rate Manufacturing overhead rate is calculated using some measure of production volume Non-manufacturing costs are not assigned to products continued Problems with conventional product costing systems Failure to adapt to the changing business environment Increasing levels of non-volume-driven manufacturing overhead costs Increasing proportion of non-manufacturing costs Causes of changes in costs Changing product structures Indicators of problems with a product costing system Product costing systems are likely to result in inaccurate product cost when Proportion of direct labour costs decrease Proportion of manufacturing overhead costs increase Proportion of manufacturing overhead costs, not related directly to production volume, increases Non-manufacturing costs which are product-related become substantial; and Product diversity increases Problems with costing in service businesses Service firms tend to use firm-wide volume-based overhead rates Overhead costs are increasing in importance and are increasingly non-volume driven Customers are demanding more diverse and higher quality services Increases in product diversity and in overhead costs Activity-based costing A methodology that can be used to measure both the cost of cost objects and the performance of activities Can help solve problems such as Distorted product costs Poor cost control The ABC method adopted, depends on the problems that need to be addressed An activity-based costing model The costing view Measures the cost of activities Assign activity costs or products Activity management view The nature of cost drivers Resource drivers Activity drivers Root cause cost drivers The costing view of ABC Measuring the cost of activities .
