DEVELOPING SOCIAL IDENTITY AND SOCIAL CAPITAL FOR SUPPLY CHAIN MANAGEMENT

Competition involves not firm against firm but rather supply chain against supply chain, but few studies explain theoretically the subsistence of a supply chain as a social entity or the operating mechanisms through which firms socialize to obtain better business performance. On the bases of social identity theory and social capital theory, the authors suggest that the salience of supply chain identity accumulates social capital in a supply chain, which then facilitates supply chain management and improves business performance.     

CONSTRUCTING IMPACT FACTORS TO MEASURE THE INFLUENCE OF SUPPLY CHAIN MANAGEMENT AND LOGISTICS JOURNALS

Data from ten supply chain management and logistics journals are combined with data from the ISI Web of Science database to develop a series of impact factors. The resulting constructed impact factors provide a context for comparing and ranking leading academic supply chain management and logistics journals. They also provide an objective way of comparing the relative influence of supply chain management and logistics journals, as well as a platform for comparing their influence with that of journals in more general fields like management and business.     

THE IMPACT OF SARBANES‐OXLEY ON OFF‐BALANCE SHEET SUPPLY CHAIN ACTIVITIES

This study seeks to provide readers with an overview of sections 401, 404 and 802 of the Sarbanes‐Oxley Act as they pertain to supply chain managers, while empirically assessing the impact of SOX on some of the most common off‐balance sheet supply activities from familiarity, compliance, and time spent perspectives. Agency theory is used to provide the theoretical foundations for this study. The results of this study provide important implications for supply managers such as that stronger SOX compliance has a positive impact on off‐balance sheet activities.     

A STRUCTURAL EQUATION MODEL OF SUPPLY CHAIN MANAGEMENT STRATEGIES AND FIRM PERFORMANCE

This research develops and analyzes a theoretical framework for supplier management and customer relationship strategies, supply chain management strategy, and firm performance using structural equation modeling. Data used in the paper were collected from a comprehensive survey circulated to a wide variety of U.S. and European business executives. Based on the findings, a clearer picture of the practice and benefits of SCM and its strategic implications emerges.     

EXPLORING PROCESSES FOR CUSTOMER VALUE INSIGHTS,SUPPLY CHAIN LEARNING AND INNOVATION: AN INTERNATIONAL STUDY

This paper reports results from a study designed to assess the extent to which firms across industries and several countries lay the groundwork for and use customer value insight, supply chain learning, and innovation processes. The cross‐sectional study serves as an exploration of the theoretical relationships among these activities and their impact on perceptions of organizational performance. Through an international survey study drawing on samples from the U.S., Sweden and Denmark, the authors find support for the notions that supply chain learning and innovation processes are driven by processes aimed at studying changes in customer value and contribute to perceptions of superior organizational performance. These findings have significant implications for logistics and supply chain management.     

SUPPLY CHAIN PROCESS INTEGRATION: A THEORETICAL FRAMEWORK

The current study was undertaken to further understanding of supply chain process integration. It is suggested that supply chain integration, the practice of realigning firms' operating structures, should be understood from an internal‐external perspective and a process view. Drawing upon four theories—Strategy‐Structure‐Performance framework, the resource based view of the firm, transaction cost economics, and social network analysis—and combining industry inputs, a theoretical framework of supply chain process integration is developed. It is argued that a firm's strategic priorities are key factors of supply chain process integration. Superior performance is likely to be achieved when necessary supply chain capabilities are developed through supply chain process integration.     

DO PERCEPTIONS BECOME REALITY? THE MODERATING ROLE OF SUPPLY CHAIN RESILIENCY ON DISRUPTION OCCURRENCE

The concern and study of supply risk and supply continuity has recently come to the forefront in managing business and conducting research. This empirical study of U.S. and German firms investigates the relationship between perceived supply risk sources and supply disruption occurrence, as well as the use of supply chain resiliency practices to reduce disruption frequency. We demonstrate that supply managers' concerns with risk emanating from suppliers and the supply market are positively related to supply disruption occurrence. We further show how and when implementing flexibility and redundancy may reduce the effects of supply disruptions.     

SUPPLY CHAIN MANAGEMENT: THE PURSUIT OF A CONSENSUS DEFINITION

As disciplines evolve, it is a normal part of the maturation process to regularly examine the definition of the discipline — i.e., what the discipline is and is not. The opinions of those involved in the discipline are key to this maturation (i.e., definitional) process. Developing a consensus definition of supply chain management is a widely discussed but unresolved challenge. Thus, the current study provides insight into the perceptions of logistics professionals regarding this issue based upon an Internet‐based survey.     

AN INVESTIGATION INTO THE EFFECT OF FULL‐SCALE SUPPLY CHAIN MANAGEMENT SOFTWARE ADOPTIONS ON INVENTORY BALANCES AND TURNS

Supply chain management (SCM) software vendors, analysts, and others claim that firms implementing SCM software stand to benefit by being able to reduce inventory holdings and increase inventory turns. We theorize that full‐scale implementations lead to system‐wide inventory optimization, which in turn leads to cost improvement associated with inventory balances and turns. To examine the question, we develop an analytical model of inventory optimization, then analyze the effects of the model with a numerical experiment, and finally confirm the results with an empirical examination. We find that firm‐wide implementation is significant in explaining improvement in inventory metrics, relative to pre‐implementation metrics for our sample. Our empirical tests indicate that implementing SCM software across only a portion of the firm does not impact inventory metrics, but that the scale of implementation does. More precisely, we find that firms implementing SCM software across the entire company significantly improve both inventory turns and inventory as a percent of revenue relative to partially‐implementing firms and non‐implementers.     

DEFINING AND OPERATIONALIZING SUPPLY CHAIN PROCESS INTEGRATION

Integration has been recognized as critical to successful supply chain management. However, an extensive literature review revealed no consensus in its conceptualization. The current study attempts to address this research gap by providing a better definition and operationalization of supply chain process integration. With empirical support, it is proposed that internal and external supply chain process integration should be treated as two separate constructs, each comprised of two dimensions: connectivity and simplification.     

AN INVESTIGATION OF THE VALUE OF CROSS‐DOCKING FOR SUPPLY CHAIN MANAGEMENT

Cross‐docking is the practice of transferring materials from an incoming shipment directly to an outgoing shipment without storing them at the transfer point. This essentially eliminates the inventory‐holding function of a warehouse and can reduce supply chain costs. We investigate the value of one type of cross‐docking in a variety of supply chain environments.     

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.     

AN ANALYSIS OF SUPPLY CHAIN COLLABORATIONS AND THEIR EFFECT ON PERFORMANCE OUTCOMES

This research examined how operational outcomes, relational outcomes and business performance are affected by a collaboration project between buyers and suppliers in a supply chain. It is hypothesized that interdependence of knowledge and process, supply chain partner insight, and the level of collaboration between the firms affect the outcomes of a collaboration project. Survey data from buyers and suppliers from a wide range of industries and organizations were used in this analysis. Among these participants, higher levels of collaboration led to improvements in operational and relational outcomes, which together led to improvements in asset utilization, competitive position, organizational performance, and profitability.     

ENSURING SUPPLY CHAIN RESILIENCE: DEVELOPMENT OF A CONCEPTUAL FRAMEWORK

The views expressed in this article are those of the authors and do not necessarily reflect the official policy or position of the Air Force, the Department of Defense, or the U.S. Government. In a world of turbulent change, resilience is a key competency since even the most carefully designed supply chain is susceptible to unforeseen events. This article presents a new Supply Chain Resilience Framework to help businesses deal with change. The conceptual framework is based on extant literature and refined through a focus group methodology. Our findings suggest that supply chain resilience can be assessed in terms of two dimensions: vulnerabilities and capabilities. The Zone of Resilience is defined as the desired balance between vulnerabilities and capabilities, where it is proposed that firms will be the most profitable in the long term. We identified seven vulnerability factors composed of 40 specific attributes and 14 capability factors from 71 attributes that facilitate the measurement of resilience. The article concludes with managerial implications and recommendations for future research.     

THE INTELLECTUAL STRUCTURE OF SUPPLY CHAIN MANAGEMENT: A BIBLIOMETRIC APPROACH

Now that supply chain management has a two‐decade research history, it is possible to examine the literature to identify whether there is any latent intellectual structure using bibliometric tools. The study applies a citation and co‐citation approach to reveal four clusters of research that have emerged. One cluster has strong ties to the logistics field, with primarily conceptual articles. A second cluster finds its roots in operations research, and consists mainly of modeling articles. The application of multidimensional scaling, cluster analysis, and factor analysis on co‐citations demonstrated a clearly identifiable structure. The structure is examined and implications for the future development of supply chain research are discussed.     

DEMAND COLLABORATION: EFFECTS ON KNOWLEDGE CREATION,RELATIONSHIPS, AND SUPPLY CHAIN PERFORMANCE

While demand collaboration is crucial to supply chain performance, there is divergence over what demand collaboration really means. Currently, one perspective stresses the use of electronic communication systems for real‐time data exchange (e.g., EDI, VMI) to increase speed of response and reduce costs, thereby improving operational efficiencies. Another perspective stresses relational elements to create close, long‐term links. These links, facilitated largely through the use of non‐electronic communication channels, serve the purpose of developing complementary capabilities, sharing more information, and engaging in more joint planning. In this study, we provide a framework that considers both elements of demand collaboration individually and jointly. The relative effectiveness of the various forms of demand collaboration is assessed via the use of a controlled simulation experiment.     

THE ROLE OF LOGISTICS MANAGERS IN THE CROSS‐FUNCTIONAL IMPLEMENTATION OF SUPPLY CHAIN MANAGEMENT

There is confusion about the domain of supply chain management, and the functions and processes that should be included. In this paper, we describe the key supply chain management processes, the role of logistics managers in each of these processes, and what the logistics function gains from this involvement.     

THE SUCCESSFUL CROSS‐DOCK BASED SUPPLY CHAIN

A supply chain using the cross‐dock approach can speed goods from upstream suppliers to downstream customers quickly and cost‐effectively, with benefits to the entire chain, if the appropriate type of cross‐dock is chosen and then designed, staffed and managed for effective performance. Unlike a warehouse, which offers storage, a cross‐dock is a high performance rapid transit point that does not provide storage. Although cross‐docks have been studied with some thoroughness, what has not been seen clearly is that a cross‐dock does not operate in isolation and therefore can't be optimized independently from the upstream and downstream processes. To be successful, cross‐dock optimization makes demands for high performance on all members of the supply chain in terms of speed, effective planning, high reliability, near error‐proof processes and a high degree of transparency, visibility and information‐sharing; accordingly, the article refers to this integrative perspective as a “cross‐dock based supply chain.” To make clear this interdependency between the cross‐dock and the chain based on it, a new definition that classifies types of cross‐dock based supply chains is offered. To assist scholars analyzing and industry management choosing a cross‐dock approach, cross‐dock based supply chains are classified as falling into three different types. Lastly, based on field work in industry and on literature review, nine critical success factors for cross‐dock based supply chain operations are offered.     

UNDERSTANDING THE FINANCIAL CONSEQUENCES OF THE BULLWHIP EFFECT IN A MULTI‐ECHELON SUPPLY CHAIN

This article is concerned with how supply chain strategies can mitigate the Bullwhip Effect and inflated inventories from the perspective of the central firm (typically a manufacturer) in the supply chain. We first outline a base case scenario with a validated system dynamics simulation model, using supply chain characteristics as reported by a real firm, in this case a Mexican electronics supplier to U.S. automobile assemblers. We find, surprisingly, that a lower Bullwhip Effect Index (BE) does not always lead to lower costs in the supply chain studied. Furthermore, sensitivity analysis suggests some interesting, counterintuitive results. The implications of these findings are further developed as we test how lead time reduction can also reduce the Bullwhip Effect in the simulated setting.
