A commentary on the applications of activity-based costing

Activity-based costing (ABC) has, within the last decade, generated a voluminous literature which has paralleled its increase in popularity with practitioners. This paper reviews ABC's potential by examining applications of it which extend throughout the core areas of management accounting. Consideration is given not only to how it has positively contributed to practice in these areas but also to its rationale and limitations to particular applications. Assessment is also made of how it interacts with longer established management accounting issues such as the variable versus fixed costing debate for income measurement and decision-making, the use of contribution margin analysis, organizational slack in the budgetary control process and conventional variance analysis. Some conclusions are drawn on its value to practitioners and researchers.     

Towards explaining activity-based costing failure: accounting and control in a decentralized organization

Many of the activity-based costing (ABC) systems introduced in recent years are said to fail (e.g. Cooperet al., 1992; Argyris and Kaplan, 1994; Shields, 1995; Roberts and Silvester, 1996). The use of ABC for surveillance by the group management, with no consequent actions, leads us to propose that claims on ABC failure result, in part, from assessing the use and value of ABCs from the decision-making perspective. The decision-making perspective may be insufficient for capturing the multitude of uses to which ABCs are put in practise. As this study shows, in the context of strategic decision-making the success of ABC cannot depend on whether its results require any actions or decisions to be taken, but on its ability to make a correct diagnosis of the situation. Consequently, some of the so-called ABC failures may not be failures. They may merely reflect a limited appreciation of the uses of accounting and control systems in practise. Nevertheless, failures and resistance are real in a number of organizations. This study explored the origins of resistance to ABC in a case setting, looking at diverse interests of organizational stakeholders, and the role of existing control and information systems in ABC implementation. We show that the resistance may have several sources; some related to the cost and benefits of ABC, some associated with organizational power and politics, and some pertinent to organization culture. The practical implication of this study hinged on the notion that although the resistance to ABC may come from various sources, these sources appear fundamentally structural and are unlikely to be dealt with by employing implementation-based strategies.     

Assessing self-selection and endogeneity issues in the relation between activity-based costing and performance

Studies investigating the relation between ABC adoption and performance are inconclusive and plagued with econometric problems. This study extends prior research to investigate the association between ABC adoption and four manufacturing plant performance measures (cycle-time improvement, quality improvement, cost improvement, and profitability) and to assess selection bias and the endogenous nature of their relationship. I use the Heckman (1979) model to assess sample selection bias and the Wooldridge (2002) 2SLS-IV approach, to investigate endogeneity. After controlling for sample selection bias and endogeneity, the coefficient of ABC under the Heckman method and ABC_fit under the 2SLS-IV method becomes significantly higher compared to the coefficient of ABC under the OLS method. In addition, both the inverse Mills ratio, under the Heckman model, and Hausman F-test, under the Wooldridge 2SLS approach, are positive and significant, confirming the presence of both sample selection bias and endogeneity. Overall, I find that controlling for sample selection bias and endogeneity is essential in properly assessing the significance of ABC-performance association.     

The relationship between product diversity, usage of advanced manufacturing technologies and activity-based costing adoption

This paper examines the associations between product diversity, usage of advanced manufacturing technologies (AMT) and activity-based costing (ABC) adoption. Theory strongly suggests that product diversity is a major determinant of the demand for ABC systems. To date, the results of empirical research on the relationship between product diversity and ABC adoption have generally been inconclusive, however, suggesting that there either may be no strong relationship, or that methodological issues may have prevented researchers from consistently finding it. Using a dataset of survey responses from 191 Dutch, medium-sized manufacturing firms, this paper re-examines the relationship between product diversity and ABC adoption. Improving upon the measurement of product diversity and distinguishing between ABC adoption and use, it examines whether the relationship is curvilinear (inverted U-shaped) and/or moderated by usage of AMT. The paper contributes to the literature by showing that, consistent with the underlying theory, product diversity, on average, is positively related to both ABC adoption and ABC use, but also that these relationships are indeed inverted U-shaped and that the relationship with ABC use is negatively moderated by usage of AMT.     

Enhanced ABC costing for hospitals: directed expense costing

Space limitations do not allow a complete discussion of all the topics and many of the obvious questions that the preceding brief introduction to directed expense costing probably raised in the reader's mind. These include how errors in accounting practices like posting expenses to the wrong period are handled; and how the system automatically adjusts costs for expenses benefiting several periods but posted to the acquisition month. As was mentioned above, underlying this overtly simple costing method are a number of sophisticated and sometimes complex processes that are hidden from the normal user and designed to automatically protect the integrity and accuracy of the costing process. From a user's viewpoint, the system is straightforward, understandable, and easy to use and audit. From a software development perspective, it is not quite that effortless. By using a system that is understood by all users at all levels, these users can now communicate with each other in a new and effective way. This new communication channel only occurs after each user is satisfied as to the overall costing quality achieved by the process. However, not all managers or physicians are always happy that the institution is using this "understandable" cost accounting system. During one of the weekly meetings of a hospital's administrative council, complaints from several powerful department heads concerning the impact that the use of cost data was having on them were brought up for discussion. In defending the continued use of the system, one vice president stated to the group that cost accounting does not get any easier than this, or any less expensive, or any more accurate. The directed expense process works and works very well. Our department heads and physicians will have to come to grips with the accountably it provides us to assess their value to the hospital.     

Teaching note: Traditional and activity based costing systems

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.     

IFRS adoption: A costly change that keeps on costing

This paper documents the results of a study exploring the transitionary and ongoing costs incurred by Australian companies from their use of IFRS. A longitudinal survey approach was adopted. Challenging the underlying logic of convergence, survey results highlighted that IFRS is costly for firms both in the lead up to adoption and thereafter. Specifically, the transition to IFRS imposed significant AIS, staff training and development, financial statement user education, and financial statement adjustment costs on many firms. Furthermore, many firms perceived that IFRS adoption has resulted in an ongoing increase of 20% or more on annual accounting and compliance costs.     

Speed Splasher: an interactive,team-based target costing exercise

Target costing is an important strategic cost management topic. The competitive business environment requires firms to produce products with the quality and functionality demanded by customers while at the same time selling them for prices largely determined by the market. Conventional cost management and cost plus pricing strategies are not very effective in this new environment. The design-centered and market-driven focus of the target costing process and the inability of firms to trade off quality and functionality to achieve target costs, are concepts not always easy to demonstrate in an accounting exercise. To overcome this problem, the authors have developed an interactive, in-class, team-based target costing exercise. This problem involves students in the dynamic process required to bring a product to market that simultaneously meets customer requirements for quality, functionality, and price-cost, and the firm's target profit requirement. The authors describe and explain this exercise, and provide guidelines for conducting the exercise in class.     

Activity-based costing user satisfaction and type of system: A research note

This paper examines user perceptions of Activity-based costing (ABC) performance for three different types of system in a major information and communication provider in South East Asia. Few prior ABC studies have considered the effect of system type on ABC performance. The study draws on a survey of 54 developers and 181 users of 16 different ABC systems within the organisation to produce five performance constructs (cost accuracy, cost-benefit trade-off, ABC impact, information use, and decision action). The results show that both the development inputs and user performance perceptions varied with the type of system (embedded, stand-alone, ad-hoc). While embedded systems enjoyed far stronger inputs (e.g. top management support, rewards and recognition, task significance) and greater development team cohesion than stand-alone systems, they were perceived by users to perform significantly less well. These findings suggest that system type is an important factor in assessing ABC performance.     

Battles in the costing war: UK debates, 1950-75

In the UK, 1950-75 was a lively period in the long-running debates between proponents of absorption and marginal costing. In the nexus of competing interests, management accountants advocated and defended rival costing systems with much vigour and passion. Expressed in the language of the times, these debates were 'battles' in the costing 'war'. We focus on these battles, analysing the various forces that operated upon the combatants, and locate them in the wider costing war. We conclude that no final resolution of the conflict was achieved in the twentieth century, nor is one likely in the foreseeable future.     

A survey of factors influencing the choice of product costing systems in UK organizations

This paper reports on the findings of a postal questionnaire that examines the extent to which potential contextual factors influence the characteristics of product costing systems. Prior research has mostly used the adoption or non-adoption of ABC systems to capture the characteristics of product costing systems. This research has generally been inconclusive and has been unable to establish strong links between ABC adoption and those contextual factors that have been identified in the literature that are conducive to the adoption of ABC systems. Instead of using only the adoption or non-adoption of ABC systems as a measure of product cost system design this research uses four different proxy measures of cost system sophistication to capture the characteristics of the product costing systems. This allows for a more robust test of the relations among the predictor variables and cost system sophistication. Results indicate that higher levels of cost system sophistication are positively associated with the importance of cost information, extent of use of other innovative management accounting techniques, intensity of the competitive environment, size, extent of the use of JIT/lean production techniques and the type of business sector. No association was found between the level of cost system sophistication and cost structure, product diversity and quality of information technology.
