Empirical research on supply chain management: a critical review and recommendations

Despite the growing interest in supply chain management (SCM), our understanding of the subject issue is still limited, largely due to inadequate attention being placed to theory building. To address this problem, this paper highlights some major weaknesses of the extant literature with respect to the conceptualization, operationalization, and modelling of SCM, identifies potential causes underlying these shortcomings, and gives some recommendations to improve theory development in this area. Specifically, it demonstrates that (1) the SCM construct has been perceived narrowly from the perspective of a particular traditional function of a firm; (2) the construct validity is threatened due to inadequate pre-operational explication of the content domain, among other operationalization problems; and (3) the dominant conceptual SCM models focus mainly on the practices-performance relationship, overlooking the context-practices relationship. A greater advance in theory development is possible if researchers adopt a process-based view of SCM, develop conceptual SCM models based on a context-practices-performance framework, and synthesize theories and research of SCM and those of related fields such as organization studies.
