This study examines how pooled procurement and a shared stock system across four states in an African country can improve access to essential medicines. Our analysis begins with a review of existing practices and introduces a pooled procurement approach integrated with a Continuous Review Policy (CRP). By comparing the current inventory policies of...

Supply chain disruptions regularly interrupt the normal operations of organizations, impairing their financial, operational, and service performance. Therefore, organizations must develop capabilities to enhance their resilience–their ability to anticipate, overcome, and transform after disruptions. The literature proposes that agility, adaptabilit...

Despite formal supplier diversity initiatives and lofty goals, corporate spending with diverse suppliers is about 7%. Conversely, the U.S. federal government's spending with these suppliers exceeds 25%. The government's use of set-asides, which limit the bidding on certain contracts to small or small and diverse suppliers, is one reason that might...

Replication endeavors contribute to the accumulation of scientific evidence about previously reported findings and are crucial for scientific progress. Replication studies are, however, often discouraged and rarely published in the operations and supply chain management (OSCM) discipline. In this article, we offer a framework for replications consi...

Purpose The present manuscript assesses how firms should manage frequent supply chain disruption triggers and whether these firms should use existing supply chain competencies, develop new ones or both to mitigate any adverse consequences on financial performance. Design/methodology/approach Data for the study come from a survey administered to pr...

Global supply chains operate in a volatile environment characterized by risks like the 2008–2009 financial crisis, trade disputes, and the COVID‐19 pandemic. Maritime shipping firms, the backbone of global supply chains, are particularly affected by this volatility. In response, these firms have pursued two strategies. First, they have acquired tan...

The COVID-19 pandemic resulted in severe supply disruptions and revenue losses, especially for buyers highly dependent on foreign suppliers. Unsurprisingly, scholars and industry experts claim that high dependence on any exchange partner is detrimental to buyers. The literature, however, is ambivalent about whether supply base concentration-the num...

As supply chains have become more global and complex, supply chain disruptions have become more frequent (Resilinc. Supply chain disruptions- Resioinc’s mid-year report. https://www.resilinc.com/in-the-news/supply-chain-disruptions-resilincs-mid-year-report/, 2021) and severe (Craighead et al. Decision Sciences 38(1):131–156, 2007). It is thus impe...

Supply chains are only as strong as their weakest link. Given that most supply chain disruptions occur because of first-tier suppliers, the need to examine supplier resilience in supply chain relationships cannot be overstated. However, our understanding of how customers can engage with their suppliers and facilitate supplier resilience in their re...

The supply management literature assumes that supplier selection is devoid of emotions and unaffected by the history and experience associated with a previously-selected supplier. In this paper, we relax these assumptions. Specifically, we consider the following sourcing opportunity: a sourcing professional had (alternatively, had not) recommended...

Supply networks are regularly affected by events that trigger supply disruptions, entailing severe consequences for firms and their supply networks. Hence, the ability of firms to withstand and recover from disruptions (i.e., their resilience), is vital to their long-term survival. Prior research suggests that the complexity of a firm’s supply netw...

Recent protectionist trends around the world have raised interest in newly enforced or increased tariffs and their effects on global supply chains. For firms sourcing globally, tariff introductions or increases significantly affect importing costs, which ultimately affect product costs. Such tariff changes may incentivize firms to adjust their supp...

Purpose The purpose of this paper is to explore resources or capabilities that enable medium-sized firms to be resilient, namely, to avoid and recover from supply chain disruptions. Design/methodology/approach A case-study method is employed with four medium-sized manufacturing firms headquartered in the USA that have global supply chains. Data ar...

We analyze the direct and indirect effects of two critical-component supply-disruption attributes (CONTROLLABILITY and RESPONSIBILITY) on supplier non-retention post disruption. Using a scenario-based role-playing experiment with 253 purchasing professionals, we find that the likelihood that a recovery lead (i.e., the individual assigned to the dis...

To prosper in the face of turbulent change, organizations need to improve how they deal with unexpected disruptions to complex supply chains. Companies can cultivate such resilience by understanding their vulnerabilities — and developing specific capabilities to compensate for those vulnerabilities.

Purpose – The purpose of this paper is to identify and review empirical strategic management articles that pertain to supply chain management (SCM) and are published in top management journals. Design/methodology/approach – The researchers review all articles published in five top management journals, namely, Academy of Management Journal, Adminis...

There has been widespread discussion about the transformation of ports from cargo loading and unloading facilities into integrated parts of supply chains. The contemporary view is that ports are logistics players in supply chains and their activities and performance affect the other supply chain members. Previous studies mainly focused on how a por...
