Teaching note: Traditional and activity based costing systems

Abstract

A significant portion of the current managerial accounting literature contrasts the benefits and importance of activity based costing (ABC) systems with the more traditional cost accounting systems. This paper questions this tendency of making such a stark contrast, by placing ABC systems within a wider cost accounting framework. Initially, the framework is developed by providing an overview of the product costing, control and decision making process. Also outlined are the various costing systems in terms of their objectives, advantages and deficiencies. A schema for integrating the costing process with decision making and performance evaluation criteria is then conceptualized. The role of ABC is recognized and integrated within this framework. The link between ‘traditional’ and ABC systems is also studied via an analysis of the conventional wisdom in some of the leading texts in managerial accounting. The analysis demonstrates that there is still much ambiguity in both the contrasting and the linking of ABC with the more traditional costing systems.
