Towards a multi-dimensional approach to supply management: a comparative case study.

Purpose - The article aims at contributing to a better understanding of the interdependence between supply management and the strategic position of the buying firm. Design/methodology/approach - The research follows a qualitative analysis of two cases: Adira, a family-owned manufacturer of machinery to cut steel, and Vulcano, a manufacturer of instantaneous house gas water-heaters and boilers. Findings - The article finds that supply management decisions depend not only on the network position of the buying firm, but also on the network vision of its managers. Research limitations/implications - The study is based on two contrasting cases. Further research should develop and test the findings by using other cases and methodological approaches more quantitative in nature. Practical implications - The article has three major practical implications: supply management should integrate three levels of decisions: dyadic, portfolio and network decisions; supply management does not depend solely on firms' strategic positioning and strategies, but also on managers' network theory about the role and capabilities of suppliers; and "no strategy" can also be a strategy. Originality/value - The study was conducted on the basis of a multi-dimensional model that integrates three levels of analysis: dyadic, portfolio and network. [ABSTRACT FROM AUTHOR]
