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 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.     

SUPPLY CHAIN MANAGEMENT COORDINATION MECHANISMS

There is growing interest from industry and academic disciplines regarding coordination in supply chains, particularly addressing coordination mechanisms available to eliminate sub‐optimization within supply chains. However, there is a disconnect between what is known in academic research about coordination mechanisms and what mechanisms practitioners apply and consider useful. This research fills a gap in the literature by conducting an in‐depth qualitative study of supply chain coordination mechanisms, primarily price, non‐price, and flow coordination mechanisms. Results suggest that: (1) managers prefer flow coordination mechanisms over price and non‐price coordination mechanisms; (2) supply chain orientation and learning orientation are important for the implementation of flow coordination mechanisms; and (3) technology, capital, and volume are not pre‐requisites for flow coordination mechanisms.     

A STRATEGIC FRAMEWORK FOR SUPPLY CHAIN ORIENTED LOGISTICS

The Council of Logistics Management's (CLM) name change to the Council of Supply Chain Management Professionals (CSCMP) has intensified discussions regarding the difference between supply chain management and logistics. This paper merges broadly accepted paradigms from strategic management and marketing to introduce a theoretically consistent framework that differentiates supply chain management from logistics while highlighting the complementary relationship. Supply chain management is portrayed as a firm or SBU level phenomena while logistics is expressed as a competency within supply chain management possessing both strategic and structural capabilities focused exclusively on managing the move/store activities used to fulfill customer orders. Research propositions regarding the interfaces and nature of logistics within a strategic supply chain orientation are drawn to guide thought and development in the discipline.     

THE APPLICATION OF EMPIRICAL STRATEGIC MANAGEMENT RESEARCH TO SUPPLY CHAIN MANAGEMENT

Researchers in supply chain management (SCM) have traditionally relied most heavily on the core disciplines of logistics, marketing, and operations; most are less familiar with empirical literature in strategic management. However, with the evolution of logistics into the more interdisciplinary SCM along with increasing attention within strategic management to supply chain issues, recent empirical research in strategy has much to offer. This study reviews and categorizes more than one hundred articles relevant to SCM drawn primarily from top strategic management journals.     

DEVELOPING AND MEASURING SUPPLY CHAIN MANAGEMENT CONCEPTS

To investigate the construct of Supply Chain Management and its antecedent construct of a Supply Chain Orientation, reliable, valid scales of each are needed. In this study, we developed measurement scales for a supply chain orientation (SCO) and supply chain management (SCM). Validity and reliability of the developed scales were established and the relationship between a SCO, SCM, and business performance was also established, providing evidence of nomological validity. The implications of these findings for managers and researchers are discussed.     

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.     

EVALUATING THE RELATIONSHIP BETWEEN QUESTIONABLE BUSINESS PRACTICES AND THE STRENGTH OF SUPPLY CHAIN RELATIONSHIPS

While strong relationships are consistently identified as a critical component of successful supply chain collaboration, many firms still engage in questionable business practices that threaten the trust and commitment that exists among trading partners. Survey results from logistics managers at manufacturing firms found that low to moderate levels of questionable business practices occur in relationships with customers and that the occurrence of these practices are related to lower reported levels of trust and commitment between trading partners. The results suggest that reducing questionable behaviors will increase trust and commitment, which should lead to stronger relationships and increased supply chain performance.     

THE STOCK PRICE REACTION TO SUPPLY CHAIN MANAGEMENT ADVERTISEMENTS AND COMPANY VALUE

The research examines the stock price reaction to the announcement of the adoption of supply chain management‐enhancing tools and technologies to determine whether there is a significant response from the capital markets. The results show that the adoption of supply chain management‐enhancement tools appears to be value creating. The strength of the stock price reaction is positively related to the degree of certainty regarding the publication date of the publication.     

INTERORGANIZATIONAL TIME‐BASED POSTPONEMENT IN THE SUPPLY CHAIN

This paper presents the results of empirical research on the use of time‐based postponement in a supply chain context using data collected from two manufacturers, a distributor, and a retailer. The analysis shows that implementing postponement at the firm level can result in the supply chain carrying more inventory. In order to achieve its full potential, postponement needs to be implemented across organizations in the supply chain.     

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.     

SUPPLY CHAIN MANAGEMENT IMPLEMENTATION AND PRIORITY STRATEGIES IN DANISH ORGANIZATIONS

There has been little discussion on how to prioritize and implement SCM strategies within organizations. This paper presents a decision tool to identify prioritized strategies for improving SCM implementation and validates its use in a study amongst SCM managers of 100 Danish organizations.     

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.     

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.     

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.     

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.     

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.     

PRODUCT FULFILLMENT IN SUPPLY CHAINS SUPPORTING INTERNET‐RETAILING OPERATIONS

Customer service, based on economical logistics operations across the supply chain, is key to the realization of sustainable levels of profitability in Internet retailing. Concentrating on inventory and product‐release operations, an empirical simulation model suggests that inventory centralization and market demand growth positively affect the level of cost‐effective service received by online shoppers. The results also show that under increasing demand levels, Internet retailers can provide optimal service to consumers by fulfilling orders through inventories located at their own facilities and avoid relying on inventories held elsewhere in the supply chain.     

AN EMPIRICAL EXAMINATION OF SUPPLY CHAIN PERFORMANCE ALONG SEVERAL DIMENSIONS OF RISK

This research operationalizes several supply chain risk sources and investigates their relationships with supply chain performance. The responses of 760 executives from firms operating in Germany reveal that demand side and supply side risks do have a negative impact on performance whereas regulatory, legal and bureaucratic risks, infrastructure risks, as well as catastrophic risks do not. The analysis and results augment previous research regarding the impact of supply chain risks on the operational performance of firms and shareholder value and provide a detailed analysis of supply chain risk sources as contextual variables in strategic decision‐making.
