and classified the various models. Based on this conceptualization of SCM, the existing literature was examined, in an effort to identify the extent to which these underlying elements were present in SCM academic research to date. A review of previous literature studies, as highlighted in Table 3 (Appendix A), provides the basis for how this review extends our understanding of SCM research. Burgess et.al. (2006) reviewed 100 randomly selected articles from 614 usable articles found in the ABI/Inform Database across a 19 year (1985 to 2003) period.. Their sample addressed manufacturing and consumer goods industries, and the research articles reviewed by them focused on a more narrowly defined operations management approach to Supply Chain Management. They classified the articles into four groups, namely (1) Descriptive features of SCM, (2) Definition issues, (3) Theoretical concerns and (4) Research methodological issues. They found SCM to be a relatively young field with exponential growth in interest from researchers in the recent past. The importance of this research in contrast to Burgess et al. (2006) is that instead of sampling 100 articles from a pool of 614 over a 5-year period, we examined 588 articles over 18 years. This not only makes for a more in-depth review, but provides a larger base from which to chart the maturation of the SCM field. It also helps to assess gaps in the literature and project future trends, thereby underscoring the importance and robustness of this study. Finally, Burgess et al., include books, manuscripts and conference proceedings while this research focuses solely on published articles in peer reviewed SCM journals. Carter and Ellram (2003) surveyed the articles published in the Journal of Supply Chain Management for the total period of 35 years since its launching i.e. for 1965 to 1999. Their objective was to offer a greater understanding of the evolution of purchasing and supply research over the first 35 years of the Journal of Supply Chain’s existence, and to provide guidance and prescriptions for future supply management research. They observed that nearly 90% of the journal articles under study consisted of normative literature, methodology reviews, and exploratory studies. They further noted that the use of hypothesis testing had increased significantly over the past 10 years of their review (1989- 1999), yet they consider that a greater use of hypothesis testing and the scientific method is recommended as the Supply Management discipline continued to mature. Carter & Ellram (2003) further recommended more literature reviews leading to the introduction of theoretical frameworks of supply management, and the use of more sophisticated research modeling techniques such as MANOVA/ discriminant analysis and inferential statistical techniques. They classified the articles based on a modification of the categories used by ISM, and proposed 32 categories for clear and unambiguous classification, which has proved to be a milestone and has been used in subsequent literature reviews by several researchers. The authors conclude that purchasing

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
