SUPPLY CHAIN CAPITAL: THE IMPACT OF STRUCTURAL AND RELATIONAL LINKAGES ON FIRM EXECUTION AND INNOVATION

Firms invest millions of dollars annually in developing their supply chains, with the broad goal of increasing their own performance. However, despite the significant resources deployed for supply chain development, the extent to which initiating, maintaining, and managing supply chain relationships contributes to firm success remains unclear. The current article provides conceptual development supporting the valuation of firm‐to‐firm supply chain connections from the perspective of the focal firm. Based on the social network and economics literatures, the article introduces the concept of supply chain capital, which comprises the value of both the structural configuration and relationship content of the firm's supply chain network. Following theoretical development, a non‐exhaustive set of propositions are constructed illustrating multiple ways that supply chain capital can be accrued and exploited for firm‐level benefit. Managerial recommendations for investment in supply chain capital are included, as are future directions for research in the area of supply chain networks.     

MANAGING CHANGE IN SUPPLY CHAINS: A PROCESS COMPARISON

The coordination required to successfully implement supply chain initiatives suggest that supply chain management change processes may possess some unique characteristics. Yet, empirical studies are scarce to support this logic. Using an empirical design and data obtained from managers, and drawing largely from Lewin's change process conceptualization, this study compares the process of supply chain management change to non‐supply chain management change. Further investigation into monitoring and control of supply chain management change is advised.     

The Struggle is Real: Insights from a Supply Chain Blockchain Case

Despite the anticipated benefits and the numerous announcements of pilot cases, we have seen very few successful implementations of blockchain technology (BCT) solutions in supply chains. Little is empirically known about the obstacles to blockchain adoption, particularly in a supply chain's interorganizational setting. In supply chains, blockchains' benefits, for example, BCT‐based tracking and tracing, are dependent on a critical mass of supply chain actors adopting the technology. While previous research has mainly been conceptual and has lacked both theory and empirical data, we propose a theory‐based model for interorganizational adoption of BCT. We use the proposed model to analyze a unique in‐depth revelatory case study. Our case study confirms previous conceptual work and reveals a paradox as well as several tensions between drivers for and against (positive and negative determining factors, respectively) of BCT adoption that must be managed in an interorganizational setting. In this vertical context, the adoption and integration decision of one supply chain actor recursively affects the adoption and integration decisions of the other supply chain actors. This paper contributes midrange theory on BCT in supply chain management (SCM), future research directions, and managerial insights on BCT adoption in supply chains.     

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.     

INTERORGANIZATIONAL CITIZENSHIP BEHAVIORS: AN EMPIRICAL STUDY

Exchanges among firms operating in supply chains are complex due to relational embeddedness, i.e., the extent to which relationships, rather than economic rationality, govern firm‐to‐firm interactions. For many years interfirm relationships were assumed to be best managed via coercive tactics. However, for the last two decades much attention has been given in the literature to more relational forms of governance, and recent supply chain research examining relationship nature, magnitude, and type implies the need for an alternative symbiotic explanation for supply chain relationship effectiveness. To address this void in the literature, this article introduces the concept of interorganizational citizenship behaviors (ICB's). Based on a review of literature from multiple business domains, common types of ICB's are identified, and research hypotheses are developed and tested. Future research initiatives and implications for supply chain management practice are also provided.     

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.     

An improved method for managing catastrophic supply chain disruptions

This article analyzes the differences between frequent and rare risks for supply chain disruptions, and proposes a new, improved risk measurement and prioritization method to account for the characteristics of rare risks. The varying idiosyncrasies of decision makers are integrated into this method such that risk management can be brought into alignment with an individual manager's preferences. Also woven into this tapestry is the notion of detection, which is familiar to those who have applied failure modes and effects analysis (FMEA), but novel in the arena of supply chain risk management. Rare risks in the supply chain are, by their nature, unsettling: unforeseen disruptions are always present, probability estimates are imprecise, and comprehensive data collection is impossible. These difficulties are taken into account by the presented risk management framework. While the proposed ordinal scales are perhaps unsettling to many who desire greater precision, measurement methods must fit the precision that is possible. By considering rare risks along with frequent risks, managers can be better positioned to deal with the unforeseen.     

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.     

A SUPPLY CHAIN‐ORIENTED APPROACH OF WORKING CAPITAL MANAGEMENT

This article analyzes and illustrates the role of payment terms for working capital improvements in supply chains. So far, research has shown how individual industries and powerful companies were able to enhance their cash‐to‐cash cycles at both their supplier's and customer's expense. From a “network perspective,” the exploitation of individual advantages by a single powerful company lowers the overall financial wealth of the supply chain. Therefore, a collaborative working capital management approach is proposed, by which the cash‐to‐cash cycles of companies with the lowest weighted average cost of capital (WACC) should be extended, while companies with higher financing costs are relieved by a shortened cash‐to‐cash cycle. An unequal distribution of power, however, between supply chain members can be the main hindrance for developing a collaborative working capital management solution.     

Planned disruption and unintended consequences: Postponement by strategy vs. intervention in the U.S. beer supply chain

Supply chain strategies are used to increase efficiency, save money, or reduce uncertainty and disruption. Disruptions can be unexpected and potentially devastating for supply chains. However, sometimes supply disruptions are built into supply chains using a postponement strategy. When postponement is implemented as a supply chain strategy, it can smooth the flow of goods, provide cost savings, and improve customer experience. When postponement is forced on supply chains via government intervention it can break down the seamless flow of goods and information, causing them to work inefficiently. In this article, we show how intervention through postponement creates unintended consequences that negatively impact beer supply chains and make recommendations to help managers mitigate these consequences. We also address policymakers, who can decrease the likelihood of unintended consequences resulting from regulations they enact—including how to prevent legislating these regulations in the first place.     

Considering Supply Chain Management's Professional Identity: The Beautiful Discipline (Or, “We Don't Cure Cancer,But We Do Make a Big Difference”)

In recent months, we have participated in various discussions on the future of logistics and supply chain management (SCM). As the newest business discipline, it is not surprising that SCM is going through growing pains and seeking to chart its future course and define a meaningful destiny. Considering professional identity—that is, who are we and what do we do—is a natural part of maturation. As JBL exists to help construct the discipline's identity, we address SCM's value‐creation competence as a source of identity construction. As we explain, SCM's economic and social contributions are not just noteworthy but remarkable. Modern SCM makes a difference to the people of the world, driving economic growth and raising living standards. Truly, it is a good time to be a supply chain professional. Much research, however, needs to be conducted if we are to fulfill SCM's value‐creation promise.     

THE DOMAIN AND SCOPE OF SCM'S FOUNDATIONAL DISCIPLINES — INSIGHTS AND ISSUES TO ADVANCE RESEARCH

The authors examine and take stock of the changing nature and landscape surrounding supply chain management, and the related disciplines of purchasing, operations management, logistics and marketing channels of distribution. They identify, describe and synthesize the nature of research in those academic disciplines that are identified to be some of the objectives with respect to supply chain management's integration goals. Their examination highlights the considerable evolution and significant advances occurring within and among these disciplines. Additionally, they find this new landscape to provide both insights and issues for scholarship to those attempting to understand the evolving nature of supply chain management and its related fields. Such insights and issues suggest a number of proposals for progress with regard to SCM's future development.     

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.     

ACTION RESEARCH IN SUPPLY CHAIN MANAGEMENT—A FRAMEWORK FOR RELEVANT AND RIGOROUS RESEARCH

In this article we present a framework that researchers can use when they prepare and conduct Action Research (AR) projects. Authors can also use the framework as a guide for how to write relevant and rigorous AR articles. AR is an applied form of case‐based research that can provide exceedingly relevant research in applied fields such as supply chain management. At the same time, AR is also a criticized research approach, particularly in terms of research rigor. With the ambition to address, as well as bridge, the gap between the relevance and rigor within AR research, we first develop a comprehensive research methodology framework that synthesizes the crucial aspects of the AR research methodology. Secondly, we review existing AR articles within logistics, operations management, and supply chain management and present the current state of AR research. After a critical review of the existing articles using our framework, we delineate vital aspects that should be addressed in future AR research. As relevance and rigor are not at odds, we believe that our comprehensive framework will pave the way for a growing stream of rigorous, as well as relevant, AR research.

Information Sharing in Global Supply Chain Alliances

The post–WWII economic expansion of economies such as Japan, South Korea, Hong Kong, Taiwan, Singapore, and more recently China and India was enabled to a significant degree by the increasingly complex, global supply chain networks of large Original Equipment manufacturers (OEMs) in the United States, European Union, and Japan. By linking buyers and suppliers across countries and industries, supply chain management (SCM) practices have a large impact on the economic fortunes of companies and countries throughout the world. Nowhere has the effect of this mutual interdependence been felt more strongly than between the U.S. companies and the Asia-Pacific market. Although the benefits of SCM are well documented, some evidence suggests that the reality of SCM implementation can create additional pressures for suppliers. We identify key problem areas experienced by suppliers and their link to the type of information shared by buying firms. The problem area experienced by most suppliers relates to issues of dependence in the alliance. Mere information sharing is insufficient for a successful alliance, and more information can be associated with a number of problems. For example, lack of information sharing can be associated with a supplier's perception of the buyer expecting excessive support. However, greater information sharing can be associated with a supplier's perception of the buyer passing on an excessive burden. Sharing of financial information is perceived as intrusive and controlling. These apparent contradictions uncover the complexity of the supply chain alliance. The moderating factors appear to be open communication and joint sharing of problem solving procedures—factors identified by suppliers that define a world-class buyer.     

OVERCOMING SPREADSHEET RISK IN SUPPLY CHAIN MODELING

Spreadsheet optimization modeling plays an important role in the management of today's sophisticated supply chains. However, despite the advantages of spreadsheets (or in some cases because of these advantages) there are significant risks associated with spreadsheet models. Spreadsheet risk is defined as the chance of adverse operational or financial consequences due to erroneous creation, maintenance, and/or use of spreadsheet models. Such errors arise because the intrinsic complexity of optimization models is beyond the expertise of many non‐technical managers. In this article we discuss procedures that we developed for managing the substantial risks associated with the use of spreadsheets for supply chain optimization. The issues we address go far beyond simple data entry mistakes, which are possible in virtually every aspect of business and can never be completely eliminated.     

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.     

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.
