The Journal of Supply Chain Management (JSCM) is a hallmark in the academic field of operations and supply chain management. During the past 50 years, it has contributed substantially to the recognition and adoption of purchasing and supply management (PSM) as an academic and strategic business domain. Having been invited by the JSCM editors to provide some ideas on the future directions of PSM research, the authors discuss what can be done to further increase both its relevance and rigor. Rigor and relevance in academic research are interconnected. To improve its relevance, the authors argue that future PSM research should better reflect the strategic priorities raised in the contemporary strategic management literature. Next, future PSM research should be much better embedded in a limited number of management theories. Here, stakeholder theory, network theory, the resource‐based view of the firm, dynamic capabilities theory, and the relational view could be considered as interesting candidates. Rigor is connected with robustness of academic research designs and projects. To foster its rigor, future PSM research should allow for an increase in the number of replication studies, longitudinal studies, and meta‐analytical studies. Future PSM research designs should reflect a careful distinction between informants and respondents and a careful sample selection. When discussing the results of quantitative studies, future PSM research should report on effect sizes and confidence intervals, rather than p‐values. Adoption of these ideas would have some important implications for both the academic PSM community and academic journal editors.

I n this paper, we investigate how interorganizational networks and interpersonal networks interact over time. We present a retrospective longitudinal case study of the network system that developed a novel aircraft material and analyze change episodes from a structurationist perspective. We identify five types of episodes in which interpersonal and interorganizational networks interact (persistence, prospecting, consolidation, reconfiguration, and dissolution) and analyze conditions for these episodes and sequences among them. Our findings advance a cross-level perspective on embeddedness and show how individuals may draw on relational and structural embeddedness as distributed resources. The multiple levels of embeddedness impact network dynamics by introducing converging and diverging dialectics, thereby limiting path dependence and proactive network orchestration.

Purpose-The purpose of this paper is to seek to investigate performance outcomes of vendor managed inventory (VMI) from a buyer's perspective and enablers for its successful application. Design/methodology/approach-Structural equation modelling through Partial Least Squares (PLS) is used to identify relationships between four enablers (information systems, information sharing, information quality, and relationship quality), perceived VMI success, and three outcomes (cost reductions, customer service, and supply chain control). Findings-Buyer-perceived VMI success is impacted by the quality of the buyer-supplier relationship, the quality of the IT-system and the intensity of information sharing, but not by the actual quality of the information shared. Furthermore, VMI leads to three performance outcomes: higher customer service levels, improved supply chain control and, to a lesser extent, cost reduction. Research limitations/implications-Although theory stipulates a positive impact of high quality information on the success of VMI, this study shows that the effect of information quality is limited in practice. Practical implications-The results of the survey show that purchasing managers who invest in the relationship with their suppliers and a good IT infrastructure are more likely to get better results from a VMI implementation. Furthermore, this paper shows that while most managers expect major cost reductions when implementing VMI, benefits primarily come from improved service levels. Originality/value-The study provides empirical evidence of why VMI in practice does not achieve all the benefits claimed in theory.
