“Strategic Supplier Portfolio Management: Does Top Management Team Composition Matter?”

Operations and Supply Chain Management are intrinsically linked fields. However, some firms appoint both operations managers (OM) as well as supply chain managers (SCM)to their top management teams. We investigate this phenomena by focusing on the impact that the presence of an OM may have on the firm as opposed to the presence of a SCM. To do this, we consider the firm's strategic supplier portfolio management. Strategic supplier portfolio management (SSPM) decisions impact the firm's long-term performance and are thus the responsibility of the firm’s top management team (TMT). Grounding our research in the logic of Upper Echelons Theory (UET), this paper develops hypotheses that predict how supply chain and operations managers on a firm’s TMT affect two key aspects of it’s SSPM – the geographic sourcing strategy and the supplier relationship strategy.

“Supplier-Supplier Relationships in Buyer-Supplier-Supplier Triads: Implications for Supplier Performance”

A growing number of studies and evidence from industries suggest that, besides managing the relationship with its suppliers, a buyer needs to proactively manage the relationships between those suppliers. In a buyer–supplier–supplier relationship triad, the buyer, as the contracting entity, influences the suppliers’ behaviors and the relationship between them. By considering the relationships in such a triad, we are able to gain a richer and more realistic perspective of buyer–supplier relationships. In this study, our goal is to examine supplier–supplier relationships in buyer–supplier–supplier triads, focusing on how such relationships impact the supplier performance. We frame the supplier–supplier relationship as co-opetition—one in which competing suppliers work together to meet the buyer's requirements. We investigate the role of the buyer on such relationships, and how the buyer and co-opetitive supplier–supplier relationships affect supplier performance. We find mixed empirical support for our hypotheses. However, we are able to demonstrate the dynamics of supplier–supplier co-opetition in the buyer–supplier–supplier triad. We point out the need for further studies in this area.

“Supplier-Supplier Relationships in the Buyer-Supplier Triad: Building Theories from Eight Case Studies”

Many researchers have studied how the buying company manages its relationship with suppliers (i.e. buyer”supplier relationship). Extending this genre of study, researchers have recently shown interest in investigating how the buying company manages relationships between the suppliers (i.e. supplier”supplier relationship). In other words, just as the relationship with the suppliers does, the relationships between suppliers have strategic implications for the buyer. We present in this study eight cases that describe supplier”supplier relationship dynamics. Using theory building through case studies, we identify five archetypes of supplier”supplier relationships. Each type of relationship is a unique configuration of the relational characteristics. We also present working propositions that associate the antecedent conditions that lead to these archetypes and eventual performance implications.
