Towards a Unified Definition of Supply Chain Management

A wide range of definitions of supply chain management (SCM) have been developed over the last three decades. The philosophy of SCM is based firmly on a recognition that it is only by working in a more integrated manner that competitive advantage can be maximised. However, for this to become a reality the development of common definitions and understandings between supply chain partners is a critical success factor. The corollary of this is that a lack of definitional consistency and a common understanding is an inhibitor to the successful adoption of SCM thinking in practice. This paper reviews a number of definitions of SCM, as well as discussions and analyses of such definitions. This leads to the central point posited in the paper – the need for a ‘unified definition’. Such a definitional construct, labelled the Four Fundamentals of SCM, is proposed with the core of the paper providing a narrative description of this construct based on a wide range of literature. the practical effectiveness of its application. Nonetheless, SCM has risen to prominence in recent years in both academic and commercial circles. However, there is still no universally accepted definition of what SCM is (and, indeed, is not). As pointed out in a widely cited article by Mentzer et al. (2001): Despite the popularity of the term Supply Chain Management, both in academia and practice, there remains considerable confusion as to its meaning. Some authors describe SCM in operations terms involving flow of products and materials, some view it as a management philosophy, and some view it as a management process (p. 2).

Given that the notion of intra-firm and inter-firm integration and alignment is central to SCM, there is increasing recognition among scholars and practitioners of the need for common definitions. For example, Mentzer et al. (2001) made the point that without a clear understanding of SCM, wide application of SCM in practice cannot be expected. From a research perspective, there are clear potential benefits associated with viewing the large body extant SCM literature, as well as emerging research findings, through the prism of a unified definitional construct. Following this introduction, the next section reviews a number of widely cited definitions of SCM. This leads to the central point posited by the author in this paper – the need for a ‘unified definition’. Such a definitional construct, labelled the Four Fundamentals of SCM, is proposed by the author with the core of the paper providing a narrative description of this construct based on a wide range of literature. Finally, some suggestions for further work are identified and some conclusions drawn.
