“Survey Research in Production/Operations Management: Historical Analyses and Opportunities for Improvement”

Our paper provides a comprehensive assessment of 285 survey research articles in operations management (OM), published between 1980 and 2000. Six OM journals are included in this study; they are, in alphabetical order: Decision Sciences (DS), International Journal of Operations & Production Management (IJOPM), International Journal of Production Research (IJPR), Journal of Operations Management (JOM), Management Science (MS), and Production and Operations Management (POM). In this paper, we reflect upon the state and evolution of survey research in the OM discipline across a 21-year time span and the contribution of OM journals that have published these studies. Major changes have occurred in the last 5 years of our sampling period, and two topics stood out as showing fastest ascendancy to prominence—operations strategy and supply chain management. Furthermore, over the years, the Journal of Operations Management appears to have been publishing more survey research articles and a greater variety of OM topics compared to the other five journals in our study.

“Taking the Leap from Dyads to Triads: Buyer-Supplier Relationships in Supply Network.”

A network is made up of nodes and links. The smallest unit that consists of both these network elements is a dyad made up of two nodes (a buyer and a supplier) and the link that connects them (a buyer–supplier relationship).

Naturally, the focus of the supply chain management literature has been on this dyad. For instance, a buyer affects a supplier through its supplier evaluation and certificate programs, as well as long-term agreement practices. The relationship between a buyer and its supplier has been characterized as cooperative or adversarial. We have learned a great deal about supply chains through such studies in dyadic context.

However, we submit that in a network, a dyad is not the smallest unit of a network. In fact, the smallest unit is a triad, made up of three nodes and the links that connect them. If so, how would this recognition guide us as we move forward to investigate supply chains as a network? What would be its implications to the genre of the literature on buyer–supplier relationships?
