• Constructing a total cost of ownership supplier selection methodology based on activity based costing and mathematical programming

      Degraeve, Zeger; Labro, Eva; Roodhooft, Filip (2004)
      In this paper we elaborate on a Total Cost of Ownership supplier selection methodology that we have constructed using real life case studies of three different industrial components groups in a firm. These case studies are presented in this article. Analysing the value chain of the firm, data on the costs generated by the purchasing policy and on supplier performance are collected using Activity Based Costing (ABC). Since a spreadsheet cannot encompass all these costs, let alone optimise the supplier selection and inventory management policy, a mathematical programming model is used. For a specific component group the combination of suppliers is selected that minimises the Total Cost of Ownership. TCO takes into account all costs that the purchase and the subsequent use of a component entail in the entire value chain of the company. The TCO approach goes beyond minimising purchase price and studies all costs that occur during the entire life cycle of the item in the organisation. Possible savings of between 6 and 14% of the total cost of ownership of the current purchasing policy are obtained for the three cases.

    • Drivers of cost system development in hospitals: results of a survey

      Cardinaels, Eddy; Roodhooft, Filip; Van Herck, Gustaaf (2004)
      While many hospitals are under pressure to become more cost efficient, new costing systems such as Activity-based costing (ABC) may form a solution. However, the factors that may facilitate (or inhibit) cost system changes towards ABC have not yet been disentangled in a specific hospital context. Via a survey study of hospitals, we discovered that cost system development in hospitals could largely be explained by hospital specific factors. Issues such as the support of the medical parties towards cost system use, the awareness of problems with the existing legal cost system, the way hospitals and physicians arrange reimbursements, should be considered if hospitals refine their cost system. Conversely, ABC-adoption issues that were found to be crucial in other industries are less important. Apparently, installing a cost system requires a different approach in hospital settings. Especially, results suggest that hospital management should not underestimate the interest of the physician in the process of redesigning cost systems.

    • Learning about small business profitability: the influence of management practices and owner-manager human capital 

      Maes, Johan; Sels, Luc; Roodhooft, Filip (2004)
      In a free market economy the importance of small business as a major job supplier, innovator and source of growth is widely recognized. Given the importance of small business for an economy, the survival, success and performance of these firms is an issue of continuous concern. Research that can lead to the identification of those factors associated with small business performance is of great interest to policy makers, owner-managers and their advisors. This article aims at detecting predictors of small business profitability. Our objective is to distinguish internal factors of small construction companies that enhance firm profitability. Based on the data of an empirical survey in the construction industry to which certified financial data has been added, this paper investigates the influence of owner-manager human capital characteristics and selected management practices on the profitability of small construction companies. For this purpose, we develop and test a structural model. Results indicate that industry experience and level of education of the owner-manager and management practices such as avoidance of cash credit and the use of actual costing systems contribute to higher profitability. Furthermore, owner-manager human capital characteristics influence profitability both directly and indirectly.

    • Market feedback, cost system choice and competitve pricing: the advantage of not being a leader

      Cardinaels, Eddy; Roodhooft, Filip; Warlop, Luk; Van Herck, Gustaaf (2004)
      This study experimentally investigates the value of cost report accuracy in an interactive pricing context. Market agents received feedback about their own profits via either a volume-based costing or a more accurate activity-based costing report. They also received a typical market report containing the performance of their rivals. While prior work suggested that market discipline and learning from salient competitors can overcome performance decrements due to inaccurate costing, our results imply that the corrective nature of market feedback depends on the decision maker's role in the competitive play. Compared to other participants, decision makers endowed with the role of a 'reputational' market leader are less effective in screening available market feedback because they predominantly fixate on their own cost data. Even when receiving biased volume-based costing, reputational leaders ignore valuable market signals of opponents having access to more accurate cost data. Consequently other market players can take advantage of them.

    • The joint effects of customer profitability reports and sales support diversity in effective customer pricing

      Cardinaels, Eddy; Roodhooft, Filip; Warlop, Luk; Van Herck, Gustaaf (2004)
      This paper experimentally investigates the value-enhancing effects of more accurate customer profitability analysis (CuPA) reports on customer pricing decisions and firm profitability when customers place different demands on the firm's support functions. Activity-based driven CuPA reports are contrasted against less accurate reports, either based on traditional volume-based costing or on aggregated feedback. Cost complexity of the environment was further varied by either low or high diversity in resource usage across customers depending on whether or not the most costly type of customer always consumed more resources in each of the various support functions of the firm. Results suggest that the diversity in resource requirements serves as an important 'contextual factor' for CuPA to have incremental value over the less accurate report types. Only when usage of sales support becomes more diverse, CuPA provides strong opportunities for learning resulting in more effective customer pricing and profit improvement. Results further show some profit benefits of volume-based costing reports. Even though cost allocations are more distorted, they still perform better than aggregated reports that do not allocate marketing overhead, but only in a more complex cost settings.
