Management accounting and control practices in a lean manufacturing environment

A lean strategy is rapidly becoming the dominant paradigm in manufacturing. Kennedy and Widener (2008) use a case study to develop a theoretical framework of management accounting and control practices for firms following a lean manufacturing strategy. We build on Kennedy and Widener (2008) by examining a structural equation model that provides evidence on the extent to which a lean manufacturing implementation is related to five management accounting and control practices. Using survey data from 244 US companies with an interest in lean manufacturing, we find a direct positive relation between the extent of a lean manufacturing implementation and a simplified strategic reporting system, value stream costing, visual performance measurement information, and employee empowerment. We find a direct negative relation with inventory tracking; however, we find it is conditional on the extent of top management support for change in production strategies such that firms decrease reliance on inventory tracking in the presence of strong management support. We also conclude that the management accounting and control practices work together as a package in a lean manufacturing environment as evidenced by the many direct associations among the five management accounting and control practices.     

Assessing the interaction effect of cost control systems and information technology integration on manufacturing plant financial performance

The interface between management control and information technology is an under-developed research area with a knowledge gap concerning its implications for financial performance. This study contributes to bridging this gap by investigating the interaction effect of cost control systems and information technology integration on manufacturing plant financial performance. We surveyed a sample of 518 managers of U.S. manufacturing plants, approximately evenly distributed between those using activity-based costing and volume-based costing. Using hierarchical regression analyses, results indicate that while information technology integration and cost control systems do not provide significant independent effects on plant financial performance, they do interact to positively impact manufacturing plant financial performance. Thus, our findings suggest that manufacturing plants will reap the greatest financial performance benefits from investments in activity-based cost control systems when combined with information technology integration.     

Manufacturing controls and performance: An experiment

This paper reports the results of an experiment that tests the effects of three manufacturing controls—inventory and production (pull vs push), incentives (fixed vs contingent) and quality control (process vs output)— on performance effectiveness and efficiency. The results indicate that both incentive and quality control systems affect performance efficiency, and incentives also had a significant effect on performance effectiveness. We also hypothesized and found a significant interaction of the production/inventory control system and the quality control system on performance effectiveness and efficiency.     

Drivers of tight carbon control in the context of climate change regulation

Our study examines the drivers of tight budgetary control in carbon management in the context of climate change regulation. Using the setting of New Zealand Emissions Trading Scheme (ETS), our study explores how firms manage their carbon performance using carbon-focused budgetary control. Based on a survey data from New Zealand firms, including both those with and those without an ETS compliance obligations, our results suggest that economic and regulatory environmental pressures, the level of proactiveness of emissions management strategy, the level of integration of carbon issues in strategic and operational processes and the perceived importance of carbon issues are the significant drivers of tight carbon-focused budgetary control.     

Reliance on budgetary control, manufacturing process automation and production subunit performance: A research note

The degree to which reliance can be placed on budgetary control in the assessment of production subunit performance, particularly with the advent of manufacturing process automation involving, for example, robots and CAD/CAM, is problematic. While budget-based control systems are extensively employed in organizations, such usage does not provide clear evidence of their utility as performance enhancement vehicles as advances are made in the automation of manufacturing processes. The purpose of this paper is to report the results of a study which examines the effect of automation on the link between reliance on budgetary control and production subunit performance. The findings suggest that manufacturing process automation moderates the relation between reliance on budgetary control and departmental performance. As such, firms may benefit from a reliance on budgetary control in the evaluation of production subunit performance as manufacturing processes become more automated.     

Inventories and the automobile market

This article studies the within‐model‐year pricing, production, and inventory management of new automobiles. Using new monthly data on U.S. transaction prices, we document that, for the typical vehicle, prices fall over the model year at a 9.0% annual rate. Concurrently, both sales and inventories are hump shaped. To explain these time series, we formulate an industry model for new automobiles in which inventory and pricing decisions are made simultaneously. The model predicts that automakers' build‐to‐stock inventory management policy substantially influences the time series of prices and sales, accounting for four tenths of the price decline observed over the model year.     

The impacts of inventory in transfer pricing and net income: Differences between traditional accounting and throughput accounting

This research proposes the Theory of Constraints (TOC) throughput accounting (TA) as an alternative management control mechanism in an international transfer pricing setting. We compare TA with the traditional accounting method and demonstrate that the traditional method underestimate factors as demand variation and inventories, which affects decisions, such as moving production to an offshore plant. A detailed system dynamics model is built to simulate the production process in an offshore supply chain to compare the methods. The study aims to fill a gap in the management accounting studies and contribute to the understanding of international transfer pricing and their management controls, exploring more than just the tax savings, which are usually considered isolated from operational factors for supply chain (SC) offshoring decisions. Furthermore, we conduct a brief literature review, present the model and discuss the results. It has been observed that inventory levels are an important part of accounting, offshored supply chains, and transfer pricing. Traditional cost and accounting methods favour higher inventory levels, and they can overestimate net income results up to 70% – especially in higher demand variation scenarios – when compared to the throughput accounting.     

The use of organic models of control in JIT firms: generalising Woodward’s findings to modern manufacturing practices

Prior research indicates that technology plays an important role in the determination of management control systems. A fully developed JIT system represents a radical departure from the traditional approach to organising and managing mass production. In probing the management control implications of JIT, this study extends some well-established concepts from organisation theory to the modern manufacturing practices literature to develop a framework which suggests that mass production firms adopting JIT (a new technology) must abandon a mechanistic management control system and adopt an organic model of control. Findings from three case studies describing the control structures used in JIT firms are also presented as part of the theoretical and hypothesis development. In addition, survey results are reported which are highly consistent with the framework, indicating that Woodward’s findings (Industrial organization: theory and practice (2nd ed.). Oxford: Oxford University Press.) generalise (are robust) to a new technology. Finally, a preliminary examination into whether improvements in certain key areas are higher for those JIT firms utilising an organic model of management was performed and found to be consistent with expectations.     

Pricing discretely monitored Asian options under Lévy processes

We present methodologies to price discretely monitored Asian options when the underlying evolves according to a generic Lévy process. For geometric Asian options we provide closed-form solutions in terms of the Fourier transform and we study in particular these formulas in the Lévy-stable case. For arithmetic Asian options we solve the valuation problem by recursive integration and derive a recursive theoretical formula for the moments to check the accuracy of the results. We compare the implementation of our method to Monte Carlo simulation implemented with control variates and using different parametric Lévy processes. We also discuss model risk issues.     

Optimal credit limit management under different information regimes

Credit limit management is of paramount importance for successful short-term credit risk management, even more so when the situation in credit and financial markets is tense. We consider a continuous-time model where the credit provider and the credit taker interact within a game-theoretic framework under different information structures. The model with complete information provides decision-theoretic insights into the problem of optimal limit policies and motivates more complicated information structures. Moving to a partial information setup, incentive distortions emerge that are not in the bank’s interest. We discuss how these distortions can effectively be reduced by an incentive-compatible contract. Finally, we provide some practical implications of our theoretical results.     

Pedagogical cases in the strategic development of management accounting systems

Discussion of the ‘lost relevance’ of management accounting and the ‘gap’ between theory and practice has focused the criticism that management accounting education is built round a set of techniques applied in simplified settings. One reason for this may be the scarcity of case studies, discussing management accounting practices, which may be adopted in classroom situations. The recent promotion of ABC, throughput accounting, just-in-time (JIT) methods and performance measures to support modern manufacturing provide additional educational challenges relating to the integration of these into the accounting curriculum. There is a danger that these may also be developed as other techniques to be learned in isolated situations rather than to be applied selectively by organizations in appropriate situations. This paper offers two case studies which support class discussion of accounting requirements within a modern manufacturing and commercial environment. The cases emphasize that any one technique is inappropriate to all situations. They force examination of manufacturing and marketing policy and strategy in the development of appropriate management accounting information. The authors' experiences of using the case studies is evaluated, to determine the strengths and weaknesses of using the non-numerical cases as a basis for class discussion of contextual factors in accounting system design.     

Management control of complex,mission-critical processes

Because the failure of complex, mission-critical systems—such as certain process control and manufacturing operations—can be exceptionally costly to an organization, appropriate management control of these systems is imperative. This paper presents a theory of management control of complex systems that is the potential basis for an intelligent DSS, which would be capable of supporting human agents monitoring complex systems. The theory is derived from field studies of agent decision making under procedural guidance, and it focuses on the most crucial—and interesting—aspect of agent behavior, i.e. the decision to deviate from a procedure when the procedure is considered detrimental to the achievement of organizational goals. The theory is instantiated in a computer model of the agents' decision processes. The computer model in turn embeds a simulation of the agents' situation and goal assessment processes that produce procedural non-compliance. © 2000 John Wiley & Sons, Ltd.     

Integrating Credit Models Using Accounting Information With Loan Officers' Decision Processes

This paper focuses on loan officers' cognitive processes of problem detection and problem-hypothesis formulation, which are incorporated into a credit model when they are confronted with loan decisions. Prior credit models in banking have not directly addressed loan officers' internal processes in a loan situation. The integration of both loan officers' cognitive processes and information used in a credit model can better help explain their decision-making biases. The results presented in this paper showed that information derived from a credit model influences loan officers' problem detection and problem-hypothesis formulation, and these processes are important factors in their loan approval. To identify loan officers' decision-making processes, the approach used in this paper integrates principles from financial management, economics, and cognitive psychology with methodological developments from psychometrics and econometrics.     

ERP in action — Challenges and benefits for management control in SME context

ERP systems have fundamentally re-shaped the way business data is collected, stored, disseminated and used throughout the world. However, the existing research in accounting has provided only relatively few empirical findings on the implications for management control when companies implement ERP systems as the technological platform. Especially scarce are the findings concerning the production phase, after implementation, when the information processes, related work practices and the new information contents can be seen as established. In this paper we explored and theorized the benefits, challenges and problems for management control when an ERP system is in use, four years after the implementation. Our findings also illustrate why and under what circumstances these challenges and benefits may exist. For a holistic view of the organization our findings, based on a qualitative case study, are constructed from the viewpoints of people at different levels and functions of the organization. Top management expected a new strategic control system, but due to the many challenges it ended up with merely financial accounting based control. At the operational level, serious challenges lead to inadequate usage of the ERP system. Management control produces the financial basic data and must contend with many practical problems caused by ERP implementation.     

Management Quality and Equity Issue Characteristics: A Comparison of SEOs and IPOs

We use hand-collected data on the management quality of firms making seasoned equity offerings (SEOs) or initial public offerings (IPOs) to analyze the relationship between management quality and equity issue characteristics, and to compare the effect of management quality on SEOs versus IPOs. We hypothesize that higher quality managers are more credible to equity market investors, thereby reducing the information asymmetry they face in the market and outsiders’ information production costs. Therefore, the equity issues of higher management quality firms will have more reputable underwriters, smaller underwriting spreads, and other expenses, and smaller SEO discounts. Further, since better managers will be able to select better projects, higher management quality firms will have larger offer sizes. Finally, since SEO firms are likely to suffer from less information asymmetry compared to IPO firms, these effects will be smaller for SEOs than for IPOs. Our findings support the above hypotheses. Our direct tests of the relationship between management quality and information asymmetry, and our comparison of information asymmetry in SEOs versus IPOs provide further support for these hypotheses.     

ENERGY EFFICIENCY EVALUATION IN MANUFACTURING THROUGH AN ONTOLOGY‐REPRESENTED KNOWLEDGE BASE

Improving energy efficiency in a manufacturing company through an energy management system requires active participation of different stakeholders and involvement of different organizational entities and technical processes. Interoperability of stakeholders and entities is the key factor to achieve a successful implementation of an energy management system. Researchers have been developing approaches in applying ontologies to address interoperability issues among humans as well as machines. Ontologies have also been used for knowledge representation in different domains, such as energy management and manufacturing. In recent years, researchers have developed knowledge‐based intelligent energy management systems in buildings, especially households, which use ontologies for knowledge representation. In the manufacturing domain, ontologies have been used for knowledge management in order to provide a common formal understanding between the stakeholders, who have different background knowledge. This paper proposes an approach to apply ontology to allow knowledge‐based energy efficiency evaluation in manufacturing companies. The ontology provides a formal knowledge representation that addresses the interoperability issues due to different human stakeholders as well as machines involved in the energy management system of the company. This paper also describes the methods used to construct and to process the ontology. Copyright © 2013 John Wiley & Sons, Ltd.     

Complementary controls and ERP implementation success

Many organisations have sought to improve their competitiveness by investing in advanced information technology, such as Enterprise Resource Planning (ERP) systems. They have implemented ERP systems for a variety of reasons, including solving year 2000 issues, reengineering business processes, and facilitating e-business. The implementation of an ERP system and associated changes in business processes, however, is not straightforward. ERP implementation projects are but another example of an information systems development project that needs to be controlled, yet the implementation of an ERP system is significantly different than a traditional system implementation. Control can be exerted by both formal and informal means [Kirsch, L.J., V. Sambamurthy, D-G. Ko, and R.L. Purvis. 2002. Controlling information systems development projects: The view from the client. Management Science. 48(4): 484–498]. Research has demonstrated that single modes of control are not sufficient, rather that a portfolio of control modes should be utilized. We expand upon this concept and suggest that this need for a mix of overlapping and redundant control mechanisms identified in the literature is explained through the use of the theory of complementarity [Milgrom, P. and J. Roberts. 1990. The economics of modern manufacturing: Technology, strategy and organization. American Economic Review 80: 511–528; Milgrom, P. and J. Roberts. 1994. Comparing equilibria. American Economic Review 84: 441–459; Milgrom, P. and J. Roberts. 1995. Complementarities and fit: Strategy, structure, and organizational change in manufacturing. Journal of Accounting and Economics. 19: 179–208; Topkis, D.M. 1998. Supermodularity and Complimentarity. Princeton University Press]. Surveys of chief information officers and internal auditors were conducted to obtain data on the controls used in ERP implementations. We find that groups of complementary controls need to be employed in the implementation of ERP systems to achieve a successful implementation.     

Equilibrium Exhaustible Resource Price Dynamics

We develop equilibrium models of exhaustible resource markets with endogenous extraction choices and prices. Our analysis demonstrates how adjustment costs can generate oil and gas forward price dynamics with two factors, consistent with the behavior these commodities exhibit in the Schwartz and Smith (2000) calibration. Our two‐factor model predicts that stochastic volatility will arise in these markets as a natural consequence of production adjustments, however, and we provide supporting empirical evidence. Differences between endogenous price processes from our general equilibrium model and exogenous processes in earlier papers can generate significant differences in both financial and real option values.     

A Bangladesh soap opera: privatisation, accounting, and regimes of control in a less developed country

This paper reports an intensive case study of a soap manufacturing company in Bangladesh that was nationalised upon Bangladesh's independence in 1971 and privatised in 1993. Theoretically it is informed by Burawoy's contributions to labour process theory, especially how the consent of labour is manufactured through internal states, internal labour markets and games, and how regimes of control in less developed ex-colonial countries are transformed by state and production politics. How the role of accounting systems may shape and be shaped by these processes is traced. Nationalisation brought state attempts to manufacture consent by the methods described in Burawoy's depiction of hegemonic regimes. However, idealistic attempts to secure accountability, rational planning and control, and consent through bureaucratic means were subverted and transformed into a regime of political hegemony. Here control was secured by political interventions, often at the behest of trade unions, for party political rather than commercial ends. Detailed systems of accounting for control and accountability were maintained but became marginal, ritualistic, and de-coupled from operations. Privatisation brought changes consistent with Burawoy's prediction of coercive controls within a new despotic regime. New owners destroyed the internal state and internal labour markets and, following widespread redundancies, most workers were hired through internal subcontracting. The changes heightened worker divisions and rendered workers powerless to resist. Gaming was observed but this relieved the pressures of work intensification and proved functional to management. Significant changes to accounting controls were made. External reporting ceased in violation of legal requirements — financial accounting became the preserve of the owning family and was beset with irregularities. Budgets became more market oriented and were transmitted downwards in a physical form to reinforce coercive pressures upon managers and thence the shop floor. The paper concludes by relating the findings to a revised model of transformation of control regimes in Bangladesh
