Abstract

Purpose

The purpose of this paper is to provide a framework for identifying and managing supply quality risk (SQR).

Design/methodology/approach

The research method began with a literature study to form a grounded model of how organizations identify and perceive SQR and associate various supplier quality management practices (SQMPs) with SQR sources. The second phase consisted of structured interviews at three companies in the food machinery industry in order to refine these concepts and examine causal relationships.

Findings

The findings from this study indicate that firms may be more likely to implement integrative supply chain practices when supplier or component sources of SQR are considered to be a significant threat. Conversely, market sources of SQR were generally not perceived as being significant, and therefore do not warrant as much direct intervention in their management.

Research limitations/implications

Most previous studies on supply chain risk focus on delivery disruptions. However, there is a lack of knowledge on identifying, assessing, and managing supply risk associated with quality. By addressing these issues and outlining future research directions the authors help provide a starting point for contributing to this line of study in supply risk theory and practice.

Practical implications

The framework developed in this paper can aid supply chain professionals in understanding what constitutes SQR and providing insight to approaches for managing this form of supply risk.

Originality/value

This is the first empirical study that the authors are aware of that links various sources of SQR to specific SQMPs.

Abstract

Purpose

Firms can choose from an array of approaches for reducing the detrimental financial effects caused by unfavorable fluctuations in commodity prices. The purpose of this paper is to provide guidance for effectively estimating the financial effects of mitigating commodity price risk volatility (CPV) in supply chain management decisions.

Design/methodology/approach

This paper adopts two prominent and complementary methodologies, namely, total cost of ownership (TCO and real options valuation (ROV), to illustrate how commodity price risk mitigation strategies can be analyzed with respect to their effect on costs and performance. The paper provides insights through a case study to demonstrate the application of these methods together and establish the benefits and challenges associated with their implementation.

Findings

The paper illustrates advantages and disadvantages of TCO and ROV and how these approaches can be adopted together to contribute to effective purchasing decisions. Supply chain flexibility is a key capability but requires investments. Holistically measuring the financial effects of flexibility investments is imperative for gaining executive management support in mitigating commodity price volatility.

Research limitations/implications

This study can provide supply chain professionals with useful guidance for measuring the costs and benefits related to developing strategies for mitigating commodity price volatility. TCO provides a focus on the costs associated with the commodity purchasing process, and ROV enables the aggregation of all the costs and benefits associated with the use of the strategy and synthesizes them into the net value estimate.

Originality/value

The paper provides a comparison of different but complementary approaches, specifically TCO and ROV, for analyzing the effectiveness of CPV risk mitigation decisions. In addition, these two methods allow supply chain professionals to evaluate and control the financial effects of CPV risk, particularly the impact of mitigation on firm’s cash flows.

Abstract

Purpose

Despite their significant economic impact, small and medium-sized enterprises (SMEs) remain underrepresented in public procurement. While previous research has identified the barriers facing SMEs in public procurement markets, a knowledge gap still exists on how these barriers influence one another in a specific context.

Design/methodology/approach

This study developed a hierarchical structural model that reveals the contextual interrelationships between 14 notable barriers to SME involvement in public procurement, based on evidence from the publicly funded healthcare sector in the UK. The data were analyzed using interpretive structural modeling (ISM) and matrix impact of cross-multiplication applied to categorization (MICMAC).

Findings

The results systematically classify barriers based on their hierarchical relationships, offering a robust theoretical foundation for understanding their nature and interconnections.

Practical implications

The findings can help scholars, government administrators and politicians in government-funded healthcare systems determine the most influential barriers to SME involvement and their causes, enabling them to build viable remedies.

Originality/value

This is the first empirical study to examine the relationship between the barriers to SMEs' public health procurement, using evidence from the public health procurement context.

Abstract

Purpose

This research aims to analyse the perceptions of practitioners in three regions regarding the challenges faced by their firms during the pandemic, considered a black-swan event. It examines the strategies implemented to mitigate and recover from risks, evaluates the effectiveness of these strategies and assesses the difficulties encountered in their implementation.

Design/methodology/approach

In the summer of 2022, an online survey was conducted among supply chain (SC) practitioners in France, Poland and the St. Louis, Missouri region of the USA. The survey aimed to understand the impact of COVID-19 on their firms and the SC strategies employed to sustain operations. These regions were selected due to their varying levels of SC development, including infrastructure, economic resources and expertise. Moreover, they exhibited different responses in safeguarding the well-being of their citizens during the pandemic.

Findings

The study reveals consistent perceptions among practitioners from the three regions regarding the impact of COVID-19 on SCs. Their actions to enhance SC resilience primarily relied on strengthening collaborative efforts within their firms and SCs, thus validating the tenets of the relational view.

Originality/value

COVID-19 is (hopefully) our black-swan pandemic occurrence during our lifetime. Nevertheless, the lessons learned from it can inform future SC risk management practices, particularly in dealing with rare crises. During times of crisis, leveraging existing SC structures may prove more effective and efficient than developing new ones. These findings underscore the significance of relationships in ensuring SC resilience.

Abstract

Purchasing organizations use various strategies and techniques to minimize the chance and impact of detrimental events occurring in the supply base. Supply risk assessments are a necessary first step in managing those risks. An analysis of in‐depth interviews with purchasing professionals from nine companies indicates that purchasing organizations often create contingency plans, and implement process‐improvement and buffer strategies in response to perceived supply risks discovered in assessments. Even though risk assessments, contingency plans, and risk management efforts are generally acknowledged as being important, many of those interviewed believed that there was not enough done in their organizations to mitigate supply‐related risks.

Abstract

Purpose

This study aims to develop a hierarchical model that uncovers the relationships between challenges confronting Africa's organ transplant supply chain systems.

Design/methodology/approach

Eleven challenges (variables) were identified after a comprehensive review of the existing literature. The contextual interactions among these variables were analysed from the perspectives of health-care stakeholders in two sub-Saharan Africa (SSA) countries (Nigeria and Uganda), using Delphi-interpretive structural modelling-cross-impact matrix multiplication applied to classification (MICMAC) techniques.

Findings

The findings reveal that weak regulatory frameworks, insufficient information systems and a lack of necessary skills make it challenging for critical actors to perform the tasks effectively. The interaction effects of these challenges weaken organ supply chains and make it less efficient, giving rise to negative externalities such as black markets for donated organs and organ tourism/trafficking.

Research limitations/implications

This paper establishes a solid foundation for a critical topic that could significantly impact human health and life once the government or non-profit ecosystem matures. The MICMAC analysis in this paper provides a methodological approach for future studies wishing to further develop the organ supply chain structural models.

Practical implications

The study provides valuable insights for experts and policymakers on where to prioritise efforts in designing interventions to strengthen organ transplantation supply chains in developing countries.

Originality/value

This study is one of the first to empirically examine the challenges of organ transplant supply chains from an SSA perspective, including theoretically grounded explanations from data collected in two developing countries.

Abstract

Purpose

This study aims to examine publications of supply chain management (SCM) researchers from across the world and maps the leadership role of authors and institutions based on how prolific they are in publishing and on network measures of centrality while accounting for the quality of the outlets that they publish in. It aims to inform stakeholders on who the leading SCM scholars are, their primary areas of SCM research, their publication profiles and the nature of their networks. It also identifies and informs on the leading SCM research institutions of the world and where leadership in specific areas of SCM research is emerging from.

Design/methodology/approach

Based on SCM papers appearing in a set of seven leading journals over the 15-year period of 2001-2015, publication scores and social network analysis measures of total degree centrality and Bonacich power centrality are used to identify the highest ranked agents in SCM research overall, as well as in some specific areas of SCM research. Social network analysis is also used to examine the nature and scope of the networks of the ranked agents and where leadership in SCM research is emerging from.

Findings

Authors and institutions from the USA and UK are found to dominate much of the rankings in SCM research both by publication score and social network analysis measures of centrality. In examining the networks of the very top authors and institutions of the world, their networks are found to be more inward-looking (country-centric) than outward-looking (globally dispersed). Further, researchers in Europe and Asia alike are found to exhibit significant continental inclinations in their network formations with researchers in Europe displaying greater propensity to collaborate with their European-based counterparts and researchers in Asia with their Asian-based counterparts. Also, from among the journals, Supply Chain Management: An International Journal is found to exhibit a far more expansive global reach than any of the other journals.

Research limitations/implications

The journal set used in this study, though representative of high-quality SCM research outlets, is not exhaustive of all potential outlets that publish SCM research. Further, the measure of quality that this study assigns to the various publications is based solely on a publication score that accounts for the quality of the journals, as rated by Association of Business Schools that the papers appear in and nothing else.

Practical implications

By informing the community of stakeholders of SCM research about the top-ranked SCM authors, institutions and countries of the world, the nature of their networks, as well as what the primary areas of SCM research of the leading authors in the world are, this research provides stakeholders, including managers, researchers and students, information that is helpful to them not only because of the insights it provides but also for the gauging of potential for embedding themselves in specific networks, engaging in collaborative research with the leading agents or pursuing educational opportunities with them.

Originality/value

This research is the first of its kind to identify and rank the top SCM authors and institutions from across the world using a representative set of seven leading SCM and primary OM journals based on publication scores and social network measures of centrality. The research is also the first of its kind to identify and rank the top authors and institutions within specific areas of SCM research and to identify future research opportunities relating to aspects of collaboration and networking in research endeavors.

Abstract

Purpose

In this article, the authors aim to describe an approach used in a purchasing/supply management course at their university that provides students with a realistic, problem‐based learning experience with client involvement while maintaining consistent learning outcomes and a manageable faculty workload term after term. Students use a standardized approach to assess commodity price risk and decide upon an effective risk management strategy. The specific commodity that students analyze is selected by client companies who then actively participate in the course.

Design/methodology/approach

An illustrative case is presented describing how universities can partner with companies to integrate student projects into the curriculum using a standardized, repeatable process.

Findings

There are numerous benefits obtained for students, faculty, universities, and companies when engaging in commodity price analysis and risk management projects. These include the applied learning for students, providing new insights to companies, networking opportunities for students and companies that may lead to hiring, fostering closer relationships between universities and companies, providing research contacts and opportunities, and ensuring that the course is repeatable each semester.

Originality/value

The authors' approach capitalizes on the realism of client involvement while reducing the variation in learning outcomes and increased workload introduced by doing different types of client‐based company projects each term.

Abstract

Purchasing and supply chain management have a critical role, and significant influence, in a firm’s environmental performance. This study explores the extent of involvement that purchasing managers in Germany, the UK, and the USA have in environmental issues, versus the level they believe they should have. The environmental issues addressed in this paper are: hazardous materials, investment recovery, product design, and supply chain relationships. Overall findings suggest that purchasing managers want greater levels of participation in these environmental issues. The study also describes differences according to country. Future research is suggested to explore how purchasing managers can influence the supply chain to improve corporate environmental performance.
