In much of the current literature on supply chain management, supply networks are recognized as a system. In this paper, we take this observation to the next level by arguing the need to recognize supply networks as a complex adaptive system (CAS). We propose that many supply networks emerge rather than result from purposeful design by a singular entity.(More)
Many researchers have investigated the dynamics of buyer–supplier relationships and have, in general, posited the importance of long-term, cooperative relationships. However, the relationship between suppliers (i.e., supplier–supplier relationship) and its potential impact on the buyer–supplier relationship have not yet been considered. This research(More)

After more than two decades since quality became part of managers’ everyday lexicon, total quality management (TQM) and ISO 9000 have taken the centre stage. However, there has been much debate about how they might be related to each other. This research is a new contribution to the knowledge on the relationships between TQM and ISO 9000, and it addresses(More)
A great deal of research has focused on supply chain risk management, but the question “Which supply chain characteristics increase the frequency of supply chain disruptions?” has not received much attention from empirical research. This is a relevant question, because firms seek stability in their operations, and therefore managers need to know how the(More)
Operationsmanagers confront the challenge of decidingwhen to implement various administrative innovations such as Six Sigma, ISO 9000, and Lean. This research examines the operating performance effects of early versus late adoption of Six Sigma process improvement. Using theories of organizational learning and knowledge transfer, we develop hypotheses(More)

The debate about the impact of ISO 9000/1994 on performance has been waging since its inception. While there is a general agreement regarding the positive impact of TQM on performance, there has been less agreement among the academics about the impact of ISO 9000/1994. Perhaps in response to such debate, the new ISO 9001/2000 has appeared purporting to be(More)
The economic consequences of interdependent relationships with suppliers and customers have long been of interest to supply chain managers and academics alike. Whereas previous studies have focused on the benefits or risks of embedded relationships that accrue to buying firms, this study simultaneously investigates the effects of a supplier’s and a(More)
Even though few empirical studies have tried to actually explicate the relationship between the bullwhip effect and performance of the supplier firm, there exists a common perception for over 30 years among both practitioners and academics that the bullwhip effect naturally results in decreased firm profitability. Anecdotal evidence further suggests that(More)
