EXPLORING A GOVERNANCE THEORY OF SUPPLY CHAIN MANAGEMENT: BARRIERS AND FACILITATORS TO INTEGRATION

Supply chain management is rapidly growing as both a strategic initiative and an academic discipline. As firms increasingly include their supply chain partners in the development of business strategy, researchers will have to constantly reevaluate the underlying themes and emergent theories of strategic logistics, management, and marketing by introducing new topics and revisiting seminal extant results. As such, this research was developed to explore the important concept of supply chain integration through strategic governance theory development. Since supply chain governance is a relatively new topic, a grounded study of both new and existing integration facilitators and barriers is presented. The study was initiated with a qualitative “managerial” development of scale items followed by a full empirical analysis. The result is an industry based returning to the source methodology for testing current governance related issues in industry. Contributions include the development of multiple dimensions of supply chain governance across facilitators and barriers, an explanation of the interplay between governance facilitators of, and barriers to, integration, a discussion of strategic level managerial implications, and a call for the future extension of governance research into the theory wanting domain of logistics and supply chain management.     

Conceptualizations of Trust: Can We Trust Them?

Although logistics and supply chain management research efforts have continued to become more sophisticated, opportunities still exist for further advancement. One critical area needing improvement is enhanced scale development and validation. This study provides insights into the strengths and weaknesses of one specific construct, trust, by examining how trust has been measured in our literature. A methodology for improving scale development, the Q‐sort procedure, is used to demonstrate a need for better measurement scales. Our findings suggest that numerous measures of trust have been used for logistics and supply chain research—most of which have been borrowed from other disciplines—without significant replication. More importantly, the results illustrate that all too often content validity is less than adequate. It appears as though we are not always measuring what we want to. Greater focus is recommended for future research that examines theory‐based scale development, purification of measures, and replication of scales to further refine and improve construct measurement for enhanced survey research.     

A Compendium of Multi‐Item Scales Utilized in Logistics Research (2001–10): Progress Achieved Since Publication of the 1973–2000 Compendium

Forty years have passed since the first multi‐item measurement scales were employed through survey research to better understand important logistics concepts. Through the years, four leading logistics journals have published research containing a total of 1,670 scales within 283 articles. A 42% increase in utilization has occurred during the most recent decade. The research fully discloses the conceptualization, composition, and properties of the multi‐item survey scales utilized in the study of logistics and supply chain management theory and practice. By documenting each scale published from 2001 to 2010, the authors make comparisons with results from the 1973–2000 study. Primary findings indicate an increase in the percentage of research utilizing multi‐item scales, and an increase in the application of confirmatory factor analysis (CFA) has assisted in producing more highly acceptable psychometric properties of the scales. This implies that researchers are utilizing more highly developed scales and following strict scale‐development procedures for building more robust scales to measure concepts important for advancing our knowledge of logistics and supply chain management. The top four conceptual categories for the scales have remained the same since 1973 and account for greater than half of the scales published. Eight additions to the categories since 2001 pertain greatly to controlling our supply chains for customer, brand, and overall security benefits. The compendium of scales provides a central document to reference as researchers seek to employ highly developed survey measures.     

The Role of Social Mechanisms in Demand and Supply Integration: An Individual Network Perspective

In many industries, including retail, increased complexity of marketing strategies needs to be met with increased efficiency in product delivery, requiring integration across demand and supply facing functions of the firm. For frontline logistics employees (FLEs) of manufacturing firms who are delivering and marketing products in retail stores daily, the ability to understand both the marketing and supply implications of their actions is essential. Despite the importance of cross‐functional integration at the retail frontline, little logistics research has explored how logistics frontline employees interact with managers and each other to integrate knowledge and information. The purpose of this research is to examine the antecedents to cross‐functional integration across demand and supply functions in multiple social networks of the FLE. Mixed methods, including social network analysis, structural equation modeling, and analysis of variance, are applied to test social capital theory hypotheses regarding the impact of relational embeddedness and social mechanisms, socialization and shared interpretation, on individual demand and supply integration across friendship, key enabler, and ideation networks of the frontline employee.     

Relational and Process Multiplexity in Vertical Supply Chain Triads: An Exploration in the U.S. Restaurant Industry

Both supply chain relationships and process connections between organizational units have been studied in business research, to enhance the understanding of supply chain integration, and to explore the differential outcomes of both types of connections for business and functional performance. However, the extant research remains deficient in two ways: within individual studies, researchers have operationalized supply chain connectivity unidimensionally, with the concept of connectivity constrained to either social relations or operational/process ties while disregarding the other viewpoint. Additionally, researchers have persistently designed studies to evaluate dyadic structures, while foregoing the larger, more intricate structures representative of complex supply chains. We address these issues by modeling supply chain connectivity as having multiple relational‐ and process‐based threads comprising linkages, and by empirically testing a set of theorized relationships describing vertical triadic supply chain networks (manufacturer, broker, retailer) within the U.S. restaurant industry. We find that increased supply chain connectivity improves chain performance, but this improvement is more directly attributable to process‐based linkages than relational linkages, which impact performance only through the process mediator variable, suggesting that current theories of interorganizational relationalism may lack complete conceptualization. Implications of these findings for managers and the academy are highlighted, and areas of follow‐on research are discussed.     

A Primer on Moderated Mediation Analysis: Exploring Logistics Involvement in New Product Development

Theorizing and empirically testing moderated mediation hypotheses allows logistics and supply chain management (L&SCM) scholars to extend the boundaries of our current understanding by examining how, when, and why relationships arise between constructs central to our theories. However, while moderated mediation analyses can enrich theory in L&SCM, they are few in number, likely due to the complexities associated with their execution. In this article, we provide a didactic treatment for executing moderated mediation analysis. We do so using primary data regarding logistics involvement in new product development. In the hopes of spurring greater application of moderated mediation in L&SCM, we devise a series of recommendations that guide scholars through the process of conducting such analyses. These recommendations extend prior treatments by explaining how to address challenges associated with devising theories to undergird moderated mediation hypotheses, measuring constructs using multiple indicators, providing guidance for detecting influential cases that can unduly affect results, and integrating what results should be reported.     

Inter‐Organizational Learning in Supply Chains: A Focus on Logistics Service Providers and Their Customers

The learning process between supply chain entities is explored from the perspective of senior third‐party executives. Through grounded theory, a theoretical framework emerged that extends our understanding of learning within a supply chain by identifying the major constructs and learning stages comprising the basic social process of inter‐organizational learning. This framework provides significant insights into the complex process employed in a supply chain to share, disseminate, and store information; co‐create knowledge; and to derive a competitive advantage.     

THE EFFECT OF INVESTMENT IN INTERORGANIZATIONAL INFORMATION TECHNOLOGY IN A RETAIL SUPPLY CHAIN

The primary purpose of this research was to investigate the effect of investment in information technology in a supply chain. The results of that investigation are presented by focusing on an empirically tested supply chain relationship model containing both behavioral and operational constructs. The four behavioral constructs represented in the model are relationship trust, relationship commitment, relationship dependence, and long‐term relationship orientation. The four operational constructs represented in the model are retailer investment in interorganizational information technology, perceived supplier investment in interorganizational information technology, logistics efficiency, and logistics effectiveness. Among other findings, the results of the investigation found that perceived supplier investment in interorganizational information technology has a significant and positive effect on logistics efficiency.     

A Multidisciplinary Approach to Supply Chain Agility: Conceptualization and Scale Development

Although agility has been identified as one of the most important issues of contemporary supply chain management, the theoretical basis for understanding supply chain agility is fragmented. This research addresses the gap related to the ambiguity surrounding the dimensions and definitions of firm supply chain agility by employing a multidisciplinary literature review to gain an in‐depth understanding of agility. In addition, a comprehensive measurement instrument that draws on the foundations of social and life science theory is developed and empirically validated. The results of the research indicate that firm supply chain agility is composed of five distinct dimensions including alertness, accessibility, decisiveness, swiftness, and flexibility. Based on these elements, a comprehensive definition of firm supply chain agility is developed for further theoretical testing of the concept.     

Knowledge Management in Supply Chains: The Role of Explicit and Tacit Knowledge

We theorize, building on the knowledge‐based view and the theoretical distinction between explicit and tacit knowledge, that knowledge management capability across the supply chain manifests itself in explicit and tacit knowledge, which in turn effectuates supply chain performance. The model is tested with survey data from 195 small‐ and medium‐sized enterprises reporting on their primary supply chain. The results indicate that the supply chain's knowledge management capability manifests itself in both explicit and tacit knowledge, with the latter being influenced more strongly. Moreover, it was found that while both explicit and tacit knowledge influence supply chain performance, the latter exerts a significantly greater impact than the former. Exploratory post hoc analyses add robustness to these findings and investigate mechanisms inherent to the transformation of tacit into explicit knowledge. Overall, this research contributes to academic theory development in logistics and supply chain management by the dichotomization of knowledge types and the demonstration of their differential magnitude of effects, and to managerial practice by providing important guidance for logistics managers structuring their knowledge management efforts across supply chains.     

THE INTELLECTUAL FOUNDATION OF THE JOURNAL OF BUSINESS LOGISTICS AND ITS EVOLUTION BETWEEN 1978 AND 2007

Many logistics and supply chain management researchers have so far studied the nature of logistics and supply chain management research in terms of its domain and scope, its epistemological assumptions, and its evolution. However, the knowledge repository on which the scientific research community draws, that is, its intellectual foundation, has not yet been studied. Studying the intellectual foundation of research provides an unbiased and comprehensive picture of the development, dissemination, and utilization of its knowledge. In this article, we identify the most contributive works—in terms of citations received—that have been used in 497 articles published in the Journal of Business Logistics (JBL) between 1978 and 2007. By means of citation and co‐citation analysis, the intellectual structure of research in JBL is revealed and transformations therein are explored. Overall, the most frequently‐cited literature can be classified into six themes: physical distribution; inventory models; customer service; interorganizational relationships; competitive strategy; and empirical methodologies for socio‐scientific research. Furthermore, we determined a development in citation frequencies to these themes: literature related to physical distribution and inventory management declined over the three decades under study, whereas literature related to competitive strategy and empirical methods gained in importance. This development indicates a shift from an operational focus to a prioritization of managerial issues. Moreover, our results demonstrate a shift towards more relational and institutional research in logistics (management), which has been typically linked with the notion of supply chain management since the 1990's.     

Modeling and Analysis of Reverse Logistics

Many modeling techniques have been developed to maximize the effectiveness and efficiency of forward logistics and supply chain management. As this article will illustrate, modeling techniques can be helpful in improving the management of reverse logistics as well. Companies and researchers are just beginning to appreciate the important differences between forward and reverse chains, and there is great opportunity to apply modeling methodologies to managing reverse logistics problems and issues. This article describes how modeling techniques can be utilized to improve reverse logistics processes and aid in solving real‐world reverse logistics problems. We focus on specific reverse logistics processes that firms, which sell products, are likely to address. In fact, the area of reverse logistics has broadened of late to include many activities that were not originally part of simply returning consumer products to a retailer. Herein, we present an overview of opportunities, where improved modeling efforts should be able to provide substantial benefits to supply chain professionals.     

Logistics Professional Identity: Strengthening the Discipline as Galaxies Collide

The merger of logistics, operations, supply management, and related disciplines into the broader field of supply chain management (SCM) has brought together academic fields with different professional identities and competing visions of what SCM ought to be, what students ought to be taught, and what the priorities for research and publication should be. This raises serious concerns because logistics faculty are less numerous than faculty in related fields. Logistics professional identity risks being diluted by the merger, resulting in potentially serious consequences for the future of logistics education and research. This paper explores these issues and offers suggestions to preserve logistics' professional identity, education and research in a supply chain world. We propose that logisticians expand the journals where they publish logistics research, continuing support for strengthening the Journal of Business Logistics as the “A” journal in logistics, rethink the way we train doctoral students, and work to preserve our community both inside and outside business schools.     

Cross‐Functional Integration: Concept Clarification and Scale Development

The centrality of cross‐functional integration (CFI) to supply chain theory and practice has long been recognized. Yet researchers continue to struggle with consistently defining or measuring the CFI construct, thus limiting the utility of CFI research. This research develops (1) a comprehensive definition of CFI that synthesizes previous supply chain research and (2) a valid set of scale items that measure the conceptual domain outlined by this definition. The goal is to build a common foundation for extending knowledge on CFI's antecedents and consequences, and ultimately to improve scholars’ ability to guide a broader practitioner community still struggling to achieve integration in their organizations.

Bridging the Gap Between Strategy and Performance: Using Leadership Style to Enable Structural Elements

Successful leaders create structural elements in order to achieve the performance objectives set forth by organizational strategy. Supply chain oriented structural elements are reflected in an organization's relationships, both within the firm and with supply chain partners. In this research effort, we examine how such structural elements can be created as a means through which to enhance performance. Our hypothesized model is rooted in strategy‐structure‐performance theory and integrates elements of servant leadership theory and social exchange theory to explain how building organizational commitment via servant leadership behaviors can ultimately impact performance. We use a survey method to collect data from 158 motor carriers. The results of our structural equation model support our hypotheses and serve to extend the discussion of supply chain structural elements and the role of leadership style in achieving organizational performance.     

An Empirically Derived Framework of Global Supply Resiliency

In today’s global business environment, supply chains have increased in both length and complexity. This increase in length and complexity coupled with a focus on improving efficiency, such as lean manufacturing practices, may lead to higher levels of supply chain risk where the likelihood of a disruption severely impacting supply chain performance increases. Resilient supply chains have been touted as a means to reduce the likelihood and severity of supply chain disruptions. However, there is little empirical evidence relative to the factors that contribute to or detract from supply resiliency. Using systems theory and the resource‐based view of the firm as the theoretical underpinnings, this study provides an in‐depth systematic investigation of supply resiliency. Adopting a theory‐building approach based on a multi‐industry empirical investigation, this study derives empirical generalizations linking 19 supply chain characteristics to supply resiliency. The study culminates in a framework that could be used to assess the level of resiliency in a supply base. Building on this framework, the study also provides a supply resiliency matrix that can be utilized to classify supply chains, or supply chains segments according to the level of resiliency realized. This article concludes by proposing several future research directions and issues that may be investigated in more detail.
