Enhancing hospital supply chain performance: A relational view and empirical test

Improving hospital supply chain performance has become increasingly important as healthcare organizations strive to improve operational efficiency and to reduce cost. In this study, we propose a research model based on a relational view, delineating the factors that influence hospital supply chain performance: trust, knowledge exchange, IT integration between the hospital and its suppliers, and hospital–supplier integration. Testing results of the research model based on data from a sample of 117 supply chain executives from U.S. hospitals show positive direct effects: (1) from trust and from IT integration to knowledge exchange respectively; (2) from knowledge exchange and from IT integration to hospital–supplier integration respectively; and (3) from hospital–supplier integration to hospital supply chain performance. The results also show the following indirect effects: (1) the influences of knowledge exchange and IT integration on hospital supply chain performance are partially and fully mediated by hospital–supplier integration, respectively and (2) the influences of trust and IT integration on hospital–supplier integration are fully and partially mediated by knowledge exchange, respectively. In addition, the results show the following moderating effects: (1) hospital system membership moderates the relationships between IT integration and knowledge exchange and between trust and knowledge exchange; (2) hospital environmental uncertainty moderates the relationship between trust and knowledge exchange; and (3) trust moderates the relationship between knowledge exchange and hospital–supplier integration. Implications of the study findings and directions for future research are discussed.     

Pattern of information technology use: The impact on buyer–suppler coordination and performance

The use of information technologies between supply chain organizations has been shown to promote organizational coordination and have a positive impact on performance. Drawing from organizational theories of learning, we build on this research by proposing a model that relates the pattern of supplier use of IT to specific types of supply chain coordination activities and a comprehensive set of organizational benefits. Specifically, we evaluate how two patterns of IT use by suppliers (exploitation and exploration) relate to two specific types of coordination activities with their buyers (operational and strategic coordination), which in turn are posited to promote specific organizational benefits. Using data from 241 first-tier OEM suppliers in the computer industry, our findings show that each pattern of IT use directly promotes a specific type of coordination activity. Although both types of coordination activities are needed to achieve both strategic and operational benefits, we find each coordination activity to be uniquely promoted by a specific pattern of IT use. IT use for exploitation is found to be an antecedent to operational coordination; IT use for exploration is found to be an antecedent to strategic coordination. No crossover between pattern of use and coordination activities is found. Our findings show that to achieve a complete set of benefits, suppliers must ultimately use IT for both exploration and exploitation. These findings provide a deeper understanding of the mechanism of how the pattern of IT use can result in a comprehensive set of organizational benefits for supplier firms.     

Effects of enterprise technology on supply chain collaboration: analysis of China-linked supply chain

Supply chain collaboration has received increasing attention from scholars and practitioners in recent years. However, our understanding of how enterprise information technology facilitates supply chain collaboration is still very limited, especially with regard to Chinese enterprise ownerships such as state-owned firms, joint-venture firms and local village-owned firms. This paper extends the theory established in enterprise information technology (IT) and supply chain collaboration literature and relates it with coordination in China-linked supply chain. Drawing upon an empirical study from 177 Chinese companies, we provide three major findings: (i) uncovered the importance of leveraging enterprise IT through supply chain collaboration; (ii) identified the relationship between enterprise ownership and enterprise technology use and supply chain collaboration in China-linked supply chain and (iii) illustrated effects of supply chain collaborative activities on operational and market performance.     

Information technology and firm performance: the role of supply chain integration

This study analyzes the correlation among integrative information technology (IT), supply chain integration (SCI), and firm performance. The results show that integrative IT is positively associated with firm performance through SCI. However, the results of this study show that integrative IT does not have a positive correlation directly with firm performance. It is considered that in the relationship between integrative IT and firm performance, a new approach such as business process-oriented view arguing that performance is yielded through the primary influence of IT is necessary rather than a traditional view that sets up their direct correlations. The findings have the following implications. First, this study presents an endeavor to investigate the consequences of integrative supply chain strategy. Second, this study provides implications in decision making so that supply chain managers can use IT in an effective way.     

The effect of an ambidextrous supply chain strategy on combinative competitive capabilities and business performance

This study investigates the influence of an ambidextrous supply chain strategy on manufacturers’ combinative competitive capabilities – the ability to excel simultaneously on competitive capabilities of quality, delivery, flexibility, and cost – and, in turn, on business performance. Drawing upon March's (1991) notions of exploration and exploitation, an ambidextrous supply chain strategy is conceptualized as a simultaneous pursuit of both explorative and exploitative supply chain practices. We operationalize this concept as a second-order latent construct that captures the co-variation between exploration and exploitation within the context of a manufacturer's supply chain management strategy. Using survey-based data gathered from 174 U.S. manufacturers, we find that an ambidextrous supply chain strategy coincides with combinative competitive capabilities and business performance. Our empirical finding contradicts conventional wisdom that argues for tradeoffs between exploration and exploitation. Instead, our empirical results are in line with an emerging complementarity view advocating that supply chain managers build practices to gain operational efficiency while simultaneously searching for opportunities to gain operational advantages. In addition, we provide insights regarding the role of combinative capabilities in mediating the relationship between an ambidextrous supply chain strategy and business performance.     

The configuration between supply chain integration and information technology competency: A resource orchestration perspective

Research indicates that deploying appropriate information technology (IT) competency in a manner that fits the supply chain integration (SCI) of a firm induces superior firm performance; however, our understanding of how to empirically conceptualize and assess the performance effect of the fit remains limited. Drawing upon resource orchestration theory and the literature on fit assessment methodologies, our study employs both a contingency and a configuration perspective to conceptualize and operationalize “fit.” The results of a survey of 196 firms in China provide the first empirical evidence for the existence and nature of interrelationships between multiple components of SCI and IT competency and their effects on firm performance. In particular, fit as “moderation” approach indicates that IT competency could strengthen the relationship between SCI and both operational and financial performance. Fit as “profile deviation” approach further reveals that the more similar the IT competency configurations are to those of the top performers in the high-level SCI group, the higher their operational and financial performance are. However, in the medium- and low-level SCI groups, the SCI-IT competency fit is significantly positively associated with financial performance and insignificantly associated with operational performance. The theoretical contributions and managerial implications of the study are discussed.     

Exploring supply management status,internal collaboration and operating performance

An important internal link in the supply chain is between supply managers and their internal customers. These individuals must collaborate to determine purchase specifications, develop sourcing strategies, ensure supplier performance, and maintain effective supplier relationships. Using power and social networking as the theoretical lenses, we develop and test a conceptual model examining the supply management function’s status, supply manager’s networking behavior, collaboration with the internal customer, and operating performance (lower cost, better quality, faster delivery, and consistent delivery). We also examine the mediating effect of collaboration and networking behavior on the positive effect of status and operating performance. Data gathered in an online survey of supply management professionals are examined using path analysis. Results show that without including the mediators, supply management status is directly related to all four operating performance measures. It is also positively related to collaboration with the internal customer and networking behavior. Contrary to expectations, the supply manager’s networking behavior is not related to collaboration with the internal customer. Collaboration is positively related to all four operating performance measures. However, the supply manager’s networking behavior is only related to one operating performance measure, better quality. Mediation analysis shows that supply management status has a direct effect on faster delivery performance beyond what is explained by collaboration and the supply manager’s networking behavior. The findings suggest that organizations should look for ways to elevate the status of the supply management function to improve internal collaboration and operating performance.     

HR flexibility and firm performance: analysis of a multi-level causal model

Human resource flexibility as a construct, how it develops, and its effect on firm performance have not received adequate attention in strategic HRM literature in spite of their obvious importance in today's dynamic competitive environment. Based on a study of 98 manufacturing and 103 service firms in India, this paper addresses these issues by developing and testing a multi-level model that attempts to explore the ‘black box’ of the interlinkages between the various components of HR flexibility and firm-level human, operational, and financial outcomes. The results suggest that a certain set of ambidextrous HR practices constitute a distinct dimension of HR flexibility, beyond the dimensions of flexibilities of skill, behaviour and HR practices as already identified in the existing literature. Evidences from both manufacturing and service sectors support the notion of HR value chain that suggests that HR system has a direct impact on firm-level HR outcomes which are most proximal, and its effects on increasingly more distal operational and financial outcomes are mediated by HR outcomes that it produces. Another important finding is that HR practices as a system have both direct and indirect (mediated by behavioural flexibility) effects on firm-level HR outcomes. Existence of significant direct effects highlights the important role that HR practices play as a structural mechanism in achieving superior firm performance.     

Reviewing interfirm relationship quality from a supply chain management perspective

With the overlap of the interfirm relationship quality and supply chain management research in mind, this paper reviewed 100 recent, scientific, English-language papers on interfirm relationship quality based on a categorisation schema derived from a conceptual framework of supply chain management. We aim to contribute to the existing supply chain management literature by providing an insight into the connections of supply chain performance with buyer–supplier relationship quality from the relationship quality scholars’ perspective. Through content analysis, frequency and contingency analysis, we evaluated how the three relationship quality dimensions—information, operational, and relational dimensions—and the three types of supply chain performance—financial and market, operational, and relational performance have been reflected in the current interfirm relationship quality papers and how the scholars have tended to link them to each other. The results reveal that relational dimension plays a key role in SC relationship management and influences performance significantly. Information dimension will affect performance indirectly through relational dimension. However, the impact of the operational dimension on performance varies. In addition, buyers’ and suppliers’ perspectives on the relational drivers of their financial performance may differ. Based on the findings, we suggest promising avenues for future investigation of supply chain relationship and performance.

     

Information technology and supply chain management: a study of the food industry

This paper's topic is the use of information technology (IT) for the development of supply chain management (SCM). In today's business environment, both in academics and industry, the term SCM has become a popular paradigm. In particular, the use of IT to facilitate the development of supply chain partners is gaining interest within industry. This paper develops the topic of SCM and further develops the relationship between the use of IT, in the form of electronic data interchange, and the development of supply chain integration. The goal of using SCM along with IT is to develop a supply chain that is capable of responding more quickly and efficiently in the meeting of consumer's requirements.     

An empirical study of the impact of e-business technologies on organizational collaboration and performance

The use of e-business technologies between supply chain organizations has been thematic in recent literature. Organizational collaboration, the foundation of supply chain management, has been enabled by the development and use of e-business technologies. Organizational collaboration and information sharing, in turn, are expected to improve organizational performance. We propose and test a model of the relationship between organizational use of e-business technologies, organizational collaboration, and performance, using empirical data. Our model differs from past studies in that collaboration is viewed as two unique constructs, differentiating between intra- and inter-organizational collaboration. Our findings show that use of e-business technologies impacts performance both directly and indirectly by promoting both measures of collaboration. Intra-firm collaboration is also found to have a direct impact on organizational performance. However, the impact of inter-organizational collaboration on performance is found to be only indirect, through the impact of intra-organizational collaboration. These findings reveal the complexity of organizational collaboration, underscore the importance for companies to promote internal collaboration, and invest in information technologies that facilitate it.     

Industrial clusters with substantial carbon-reduction potential

To successfully reduce environmental emissions, companies need to expand the scope of their emissions accounting to include entire supply chains. A clustering approach has been used to find emission-intensive industry clusters. However, this approach did not include entire direct and indirect supply chains when forming high emission industry clusters. We propose a new method based on a modified normalized cut function with Leontief’s input–output model and basic clustering algorithms to find industry clusters with high levels of embodied within-cluster emissions that are well separated in the supply chain network. We use this method to identify 58 carbon-intensive clusters of Japanese industries and visualize the within-cluster supply chains in terms of embodied carbon flows. We recommend that companies collaborate within clusters to reduce environmental emissions. Our results provide new insights on where to target emissions reduction actions and technology development within industrial supply chains.     

Success factors for continuous supply chain process improvement: evidence from Japanese manufacturers

This study explores how firms can realise ‘continuous’ supply chain process improvement. Specifically, this study proposes the success factors of routinised activities (also called ‘repeated activities’) in the supply chain process improvement. Eight Japanese manufacturers are selected for the case studies. These firms are selected based on their supply chain process operation capabilities. From the case studies, we find that the planning of supply chain process improvement depends on the existing stage of the firm’s Supply Chain Management reform. In addition, even firms with high scores for supply chain process operation capabilities do not have supply chain performance systems. Furthermore, quite surprisingly, many Japanese manufacturers tend to improve their supply chain processes in the absence of such systems.     

Impact of eBusiness technologies on operational performance: The role of production information integration in the supply chain

While the information technology (IT) literature is mixed regarding the direct benefits of eBusiness technologies on performance, the impact of such technologies on supply chain practices remains largely an unexplored area of research. We hypothesize that while there may be no direct benefit of eBusiness technologies on performance, these technologies might support customer integration and supplier integration in the supply chain, which in turn might impact operating performance.To examine our hypotheses, we collected data from respondents who focused their responses to a single major product the process that manufactures it, a significant customer, and an important supplier. Our analyses showed that there was no direct benefit of eBusiness technologies on performance; however these technologies supported customer integration and supplier integration. Further, supplier integration was found to positively impact cost, quality, flexibility, and delivery performance; however there was no relationship between customer integration and performance. Consequently, there is a relationship between eBusiness technologies and supplier integration that leads to better performance. Further, there is an interactive effect between customer integration and supplier integration that supports the notion that firms that have both forms of integration, supported by eBusiness technologies, significantly outperform the others.     

The geography of suppliers and retailers

In the last decades, supply chains have increasingly transcended national boundaries developing into global supply chains. Along with the many opportunities arising from international sourcing and the extended commercial presence over the world, the management of a globally dispersed supply chain is highly complex. A key issue to consider when dealing with the global supply chain design is the location of facilities, not only with respect to firms' owned facilities but also the supply and distribution side as factors that affect supply chain complexity and operational performance. This paper sets out a methodological framework to characterize the geographical configuration of a firm's suppliers and retailer networks. Quantitative indexes of network spatial concentration and relative proximity measures based on a nonparametric kernel density estimator are developed to identify both intra- and inter-firm patterns between the supply and point of sales' distributions. The method is first described by means of a series of theoretical-illustrative examples and exemplified by analyzing the geographical dispersion of four practical cases from the fashion-textile industry (i.e., Adidas, Benetton, C&A, and Puma). Subsequently, managerial implications and potential use of the metrics are discussed, showing how the proposed approach can support researchers and practitioners to improve supply chain location decisions and logistic integration, and evaluate changes in either the purchasing or distribution strategy.

Information technology for sustainable supply chain management: a literature survey

In supply chain management (SCM), two topics have gained importance over the last years. On the one hand, sustainable SCM (SSCM) has become increasingly relevant and many publications have contributed to the topic. On the other hand, information technology (IT) is being progressively considered as a key enabler for efficiency in supply chains. Several research efforts have contributed to the field of IT for SSCM. However, this paper is the first recent attempt to summarise the current state of the art of how IT can affect SSCM in any structured way and to compare it with IT for ‘general’ SCM to give guidance for future research. This paper surveys 55 peer-reviewed articles that were retrieved through keyword searches (until May 2014). The analysis identifies research deficits as well as a lack of scientific discourse employing empirical techniques and a lack of investigations on the social sustainability. Additionally, possible topics for further research were derived by comparing the survey’s results with the current research on IT for ‘general’ SCM following the analysis of 631 articles. Six fields could be identified, namely output/effects of IT, machine communication and multiagents, inputs and IT-supported processing, IT-enabled interorganisational exchange, quantitative IT approaches and a sector focus.     

The direct digital manufacturing (r)evolution: definition of a research agenda

Direct digital manufacturing, or ‘3D printing’ as it is more commonly known, offers a wealth of opportunities for product and process innovation, and is often touted to ‘revolutionize’ today’s manufacturing operations and its associated supply chains structures. Despite a growing number of successful 3D printing applications, however, evidence of any displacement of traditional manufacturing is limited. In this paper we seek to separate hype surrounding DDM from economic reality in order to ground the future research agenda for the Operations Management field. By opposing direct digital manufacturing with traditional tool-based manufacturing, we show that direct digital manufacturing so far lags behind by several orders of magnitude compared to traditional manufacturing methods. Yet we also find that direct digital manufacturing clearly is on an improvement trajectory that eventually will see it being able to compete with traditional manufacturing on a unit cost basis. As such we conclude that direct digital manufacturing will increasingly challenge operations management researchers to question established practices such as scheduling, batch sizing and inventory management in low-volume, high-variety contexts. Furthermore, an increasing adoption of direct digital manufacturing will drive structural shifts in the supply chain that are not yet well understood. We summarize these challenges by defining the research agenda at factory, supply chain, and operations strategy level.     

Supply chain finance schemes in the procurement of agricultural products

Product, information, and finance flows are all interrelated within the modern supply chain; thus, it is now more than ever of paramount importance for practitioners to integrate procurement and financial decisions. This challenge is exemplified in many agricultural supply chains, where operational risks are significant and access to capital differs sharply across firms. We study three management tactics that some large food/beverage manufacturers – situated downstream in these chains – have used to meet the challenge: ordinary fixed price contracts (or soft tolling) with direct suppliers, hard tolling and contract farming where the manufacturer intervenes upstream, providing capital, and coordinating procurement decisions. We place these upstream intervention schemes in the theoretical context of supply chain finance (SCF) and model their application to a three-echelon agricultural supply chain. We perform a numerical study in order to understand how the structure of capital constraints in the chain may influence the manufacturer's choice of SCF scheme. The numerical study is based on a business case that reflects the barley–malt supply chain of Heineken N.V. Despite greater coordination opportunities, we show that upstream intervention is not necessarily preferable for the manufacturer. Nevertheless, the preferred SCF scheme can be inferred on the basis of relatively simple characterization of the capital constraints in the supply chain.     

A proactive approach to supply chain risk management: Shifting orders among suppliers to mitigate the supply side risks

Globalization, e-trade, advanced technologies and emerging production techniques have increased supply chains’ efficiency and added value. However, despite numerous advantages, these factors make supply chains more fragile and vulnerable to risks. For this reason, companies that perform supply chain risk management gain competitive advantage. In the past, supply chain managers mainly focused on reducing costs; but recently, they have begun to give importance to supply chain continuity and resiliency which have significant impacts on costs as well. Hence, conventional reactive planning has given way to proactive planning in supply chain risk management. In this study, the supply chain risk management process is investigated and a procedure is proposed in the risk mitigation phase. In the first stage of the proposed procedure, an initial procurement plan is obtained via a linear programming model, considering the cost criterion as the first priority. In the second stage, this plan is revised by including the risk criterion into the planning as the second priority. The aim of this procedure that enables proactive planning is to reduce the supply side risks. The model is tested with a hypothetical data set and the cost analysis is performed to evaluate the performance of the procedure. Finally, the whole supply chain risk management process including the proposed procedure is applied to an international automotive company.
