Understanding the concept of supply chain resilience

Abstract: Purpose – In the emerging disciplines of risk management and supply chain management, resilience is a relatively undefined concept. The purpose of this paper is to present an integrated perspective on resilience through an extensive review of the literature in a number of disciplines including developmental psychology and ecosystems. In addition, the paper identifies and addresses some of the current theoretical gaps in the existing research.Design/methodology/approach – Supply chain resilience has been defined by a number of disciplines. An integrative literature review is conducted in an attempt to integrate existing perspectives. This review also serves as the basis for the development of a conceptual model.Findings – The key elements of supply chain resilience and the relationships among them, the links between risks and implications for supply chain management, and the methodologies for managing these key issues are poorly understood. Implications for future research advocate testing the proposed mod...

Does firm innovativeness enable effective responses to supply chain disruptions? An empirical study

Abstract: Purpose – The purpose of this paper is to investigate the nexus of relationships linking firm innovativeness, innovation magnitude, disruption severity, and supply chain resilience. These relationships are examined within a supply chain disruptions context. Design/methodology/approach – This study employed between subjects scenario-based experimental methodology combined with a survey method. Participants in the study were senior level logistics/supply chain and operations managers in US and European manufacturing companies. The hypotheses were tested via linear regression models. Findings – Findings suggest that both firm innovativeness and innovation magnitude are positively associated with supply chain resilience. In addition, it was found that disruption severity is positively associated with innovation magnitude. Research limitations/implications – Based on the findings, the authors expect that firm innovativeness as a dynamic capability should have a positive impact on achieving supply chain resilie...

How does firm innovativeness enable supply chain resilience? The moderating role of supply uncertainty and interdependence

Abstract: Despite its potential benefits in a wide range of circumstances, firm innovativeness received scant attention in relation to managing the various risks and uncertainties in the global business environment. Likewise, there is still a limited understanding of firms’ supply chain resilience (SCR) and its related antecedents in the strategic management literature. This research focuses on exploring the relationship between firm innovativeness and SCR in an attempt to facilitate bridging the gap between two important research streams and shed some light on the contingent value of firm innovativeness against disruptions and adversities. The moderating role of supply uncertainty and interdependence in the focal relationship was also hypothesised and tested. Findings suggest that firm innovativeness is positively associated with firm SCR, and supply uncertainty negatively moderates this relationship but interdependence does not. We argue that this could be due to the dual nature of interdependence in supply networks.

The Relationship of Supply Chain Visibility to Firm Performance

Abstract: The ability to “see” from one end of the supply chain to the other is needed to effectively and efficiently manage and control global supply chain processes that span multiple firms. Supply chain v...

The Social Psychology of Groups

Abstract: The Social Psychology of Groups. J. W Thibaut & H. H. Kelley. New York: alley, 1959. The team of Thibaut and Kelley goes back to 1946 when, after serving in different units of the armed services psychology program, the authors joined the Research Center for Group Dynamics, first at M.LT and then at the University of Michigan. Their continued association eventuated in appointments as fellows at the Center for Advanced Study in the Behavioral Sciences, 19561957. It is during these years that their collaboration resulted in the publication of The Social Psychology of Groups. The book was designed to "bring order and coherence to present-day research in interpersonal relations and group functioning." To accomplish this aim, the authors introduced, defined, and illustrated basic concepts in an effort to explain the simplest of social phenomena, the two-person relationship. These basic principles and concepts were then employed to illuminate larger problems and more complex social relationships and to examine the significance of such concepts as roles, norm, power, group cohesiveness, and status. The lasting legacy of this book is derived from the fact that the concepts and principles discussed therein serve as a foundation for one of the dominant conceptual frameworks in the field of family studies today-the social exchange framework. Specifically, much of our contemporary thinking about the process of interpersonal attraction and about how individuals evaluate their close relationships has been influenced by the theory and concepts introduced in The Social Psychology of Groups. Today, as a result of Thibaut and Kelley, we think of interpersonal attraction as resulting from the unique valence of driving and restraining forces, rewards and costs, subjectively thought to be available from a specific relationship and its competing alternatives. We understand, as well, that relationships are evaluated through complex and subjectively based comparative processes. As a result, when we think about assessing the degree to which individuals are satisfied with their relationships, we take into consideration the fact that individuals differ in terms of the importance they attribute to different aspects of a relationship (e.g., financial security, sexual fulfillment, companionship). We also take into consideration the fact that individuals differ in terms of the levels of rewards and costs that they believe are realistically obtainable and deserved from a relationship. In addition, as a result of Thibaut and Kelley's theoretical focus on the concept of dependence and the interrelationship between attraction and dependence, there has evolved within the field of family studies a deeper appreciation for the complexities and variability found within relationships. Individuals are dependent on their relationships, according to Thibaut and Kelley, when the outcomes derived from the existing relationship exceed those perceived to be available in competing alternatives. Individuals who are highly dependent on their relationships are less likely to act to end their relationships. This dependence and the stability it engenders may or may not be voluntary, depending on the degree to which individuals are attracted to and satisfied with their relationships. When individuals are both attracted to and dependent on their relationships, they can be thought of as voluntarily participating in their relationship. That is, they are likely to commit themselves to the partner and relationship and actively work for its continuance. Thibaut and Kelley termed those relationships characterized by low levels of satisfaction and high levels of dependence "nonvoluntary relationships. …

Resilience: the concept, a literature review and future directions

Abstract: In an ever-more interconnected world (social, technological and environmental), no organisation can retain a competitive position and survive disruptions as an independent entity. This article provides a review of resilience literature in its widest context and later its application at an organisational level context. The origins of the concept are reported and consequently, the various fields of research are analysed. The concept is shown to remain essentially constant regardless of its field of enquiry and has much to inform the fields of organisation theory, strategy and operations management. This article identifies a number of areas for advancing resilience research, in particular: the relationship between human and organisational resilience; understanding interfaces between organisational and infrastructural resilience.

Supply chain resilience in the global financial crisis: an empirical study

Abstract: Purpose – The objective of this paper is to conceptualise supply chain resilience (SCRES) and to identify and explore empirically its relationship with the related concepts of supply chain vulnerability (SCV) and supply chain risk management (SCRM).Design/methodology/approach – From a review of the literature the conceptual domain of SCRES is defined and the proposed relationships with SCRM and SCV are derived. Data from a longitudinal case study with three supply chains are presented to explore the relationship between the concepts in the context of the global financial crisis.Findings – The empirical data provide support for a positive impact of supply chain risk (SCR) effect and knowledge management on SCRES and from SCRES on SCV. SCR effect and knowledge management seem to enhance the SCRES by improving the flexibility, visibility, velocity and collaboration capabilities of the supply chain. Thereby, they decrease the SCV in a disruptive risk event. The positive effects manifest themselves in upstream...

Resilience in business and management research: a review of influential publications and a research agenda

Abstract: This paper identifies the development of and gaps in knowledge in business and management research on resilience, based on a systematic review of influential publications among 339 papers, books and book chapters published between 1977 and 2014. Analyzing these records shows that resilience research has developed into five research streams, or lines of enquiry, which view resilience as (1) organizational responses to external threats, (2) organizational reliability, (3) employee strengths, (4) the adaptability of business models or (5) design principles that reduce supply chain vulnerabilities and disruptions. A review of the five streams suggests three key findings: First, resilience has been conceptualized quite differently across studies, meaning that the different research streams have developed their own definitions, theories and understandings of resilience. Second, conceptual similarities and differences among these streams have not yet been explored, nor have insights been gleaned about any possible generalizable principles for developing resilience. Third, resilience has been operationalized quite differently, with few insights into the empirics for detecting resilience to future adversity (or the absence thereof). This paper outlines emerging research trends and pathways for future research, highlighting opportunities to integrate and expand on existing knowledge, as well as avenues for further investigation of resilience in business and management studies.

A contingent resource-based perspective of supply chain resilience and robustness

Abstract: Understanding supply chain resilience and robustness is increasingly important for supply chain managers. This is due to the growing complexity of contemporary supply chains and the subsequent increased probability of experiencing a disruption. Few studies within the risk management literature have empirically disentangled the concepts of resilience and robustness or explored their antecedents. This study utilizes a contingent resource-based view perspective to understand the relationship between specific resources (information sharing and connectivity), capabilities (visibility), and performance in terms of supply chain resilience and robustness. In addition, it utilizes supply base complexity as a moderating factor. Survey data collected from 264 UK manufacturing plants suggest that supply chain connectivity and information sharing resources lead to a supply chain visibility capability which enhances resilience and robustness. Of the four dimensions of complexity, only scale is found to have a strong moderating effect on this relationship, while geographic dispersion, differentiation, and delivery complexity do not have contingent effects. This study highlights theoretical and managerial implications for approaches to resilience and robustness.
