Supply base rationalisation: myth or reality?

Companies throughout the UK have been claiming for some time that in order to become more competitive and flexible, and to reduce costs, they must reduce the size of their supplier bases. In recent years, extensive supply base reduction strategies have been witnessed in a wide range of firms in differing sectors. This article seeks to explore whether these strategies are truly being followed, how they have been implemented, and how successful they have been. The author finds that whilst companies have significantly reduced the number of their suppliers, such strategies have not led to the rewards that were first envisaged. It appears that this is mainly due to a haphazard approach to rationalisation, a focus on transaction cost information, and poor management of highly dependent relationships. In addition, there is now evidence that some firms are actually increasing the size of their supply bases once more, to mitigate these problems. The research found that whilst companies claimed that they had reduced their supply bases, the reality was that they still had the same numbers of suppliers — they had delegated control to `first-tier’ suppliers as opposed to reducing the supply base. This article concludes that supply base delegation may be a useful strategy; it allows firms to focus on fewer suppliers, build high-dependency relationships, share technological advantages and spend time and effort on improving fewer relationships, thus leading to more efficient resource utilisation and consequent cost reduction. However, this process needs to be conducted within a strategic framework.     

SUPPLY CHAIN COLLABORATION AND LOGISTICAL SERVICE PERFORMANCE

Collaboration with external supply chain entities influences increased internal collaboration, which in turn improves service performance. This relationship may be the key to helping managers understand how best to facilitate behavioral change. The implication is that collaborating with customers and suppliers is a first step toward effective collaboration within the firm.     

Firm Growth and Supply Chain Partnerships: An Empirical Analysis of U.K. SME Subcontractors

This paper examines the performance of a sample of 211 U.K.subcontractors to evaluate whether differences in how they manage their supply chain relationships are associated with differences in (sales and employment)growth rates over two consecutive 3 year periods from 1993 to 1999.We identified 34 firms that had close partnership relationships with members of their supply chain. Our empirical findings indicate that firms with inter-firm partnership arrangements with members of their supply chain experienced significantly higher growth rates. These results suggest that inter-firm partnerships may facilitate more rapid and sustained SME growth,though further research is required to determine the role played by partnerships and the extent to which this may vary to reflect differing owner-manager motivations and growth opportunities.     

Modelling the Impact of Environmental and Organizational Determinants on Green Supply Chain Innovation and Performance

Both customers and suppliers are becoming increasingly concerned about environmental issues in modern food chains. A firm’s decision to implement green supply chain management is based on the social objectives of the firm and its management, its desire to pursue corporate social responsibility, its relationships with channel partners, and environmental determinants such as government legislation. The speed at which green supply chain management is implemented within an organization depends on its agility and its ability to facilitate innovation. Innovation may take the form of new product development or new process development, including the introduction of environmental management systems and total quality management in both production and purchasing. This article presents a conceptual model to explain how the various theoretical constructs are related and how innovation effects green supply chain management and performance.     

Category Captain Management: a new approach for healthcare suppliers to partner with their hospital customers

Hospitals represent a substantial market for pharmaceutical and medical device companies. The typical approach by healthcare manufacturers and suppliers to hospitals is to send representatives or detailers to hospitals and meet with representatives of hospital formularies and purchasing officials. Classic channels systems, and specifically, Category Captain Management ("CCM") may provide more of a sustainable competitive advantage than traditional hospital detailing. The purpose of this article is to discuss how CCM might apply as an approach for healthcare suppliers to truly partner with their hospital customers.     

Board Composition and Corporate Social Responsibility: The Role of Diversity,Gender, Strategy and Decision Making

This study integrates the resource dependence perspective and the stakeholder perspective to analyze local Chinese suppliers’ environment strategies in response to environmental requirements of different types of customers. With a sample of 1,215 local Chinese manufacturing suppliers, we examine the impact of export intensity and environmental requirements of multinational enterprises (MNEs) on local Chinese suppliers’ environment strategies. The results show that local Chinese suppliers with high levels of export intensity are more likely to adopt positive environment strategies to reduce environmental risks. In addition, local Chinese suppliers respond actively to environmental requirements of MNE customers but not to those of local customers. The linkage between MNE customers’ environmental requirements and local Chinese suppliers’ environment strategies remains significant, even after we control for the impact of export intensity. Implications of the findings conclude the article.

Disruptions in Supply Networks: A Probabilistic Risk Assessment Approach

Supply disruptions are attracting growing attention. Even in geographically, politically and economically stable locations, companies are exposed to disruptions, because they depend on their suppliers and suppliers’ suppliers. The analysis of these disruptions helps mitigate risks: for example, instead of relying on local measures such as safety stock or insurance, a company can introduce new supply contracts or backup risky suppliers. In this article, we analyze risks caused by supplier disruptions by introducing concepts from probabilistic risk assessment (PRA), which is a widely employed methodology for the risk analysis of complex engineering systems. We apply PRA to examine simple networks such as triads analytically, and use simulation to analyze disruption risks in random networks of realistic size. We also illustrate how PRA can support strategic decisions such as whether or not to use single or multiple suppliers; which suppliers are more risky than others; and what impacts the complexity of the supply base has on the reliability of the supplier network.     

Customer concentration and corporate social responsibility performance: Evidence from China

This study examines whether and how a supplier firm’s customer concentration affects its corporate social responsibility (CSR) performance in emerging markets. Using a sample of Chinese listed firms, we find that customer concentration is negatively associated with supplier CSR performance. Cross-sectional analyses reveal that the negative relation is more pronounced in suppliers without foreign customers or foreign investors, suppliers that are non-state-owned, and suppliers operating in poor legal environments. Finally, channel tests suggest that reduced demand of disclosure from customers and limited awareness of CSR are potential mechanisms through which customer concentration negatively affects CSR performance.     

The economics of partnership sourcing versus adversarial competition: a critique

In the strategic procurement management literature two general forms of purchasing arrangement feature—‘partnership sourcing’ and ‘competition’. Usually partnership sourcing is said to be superior because it leads to long-term collaboration based on trust between buyer and supplier. One product is a reduction of the supplier base with firms perhaps relying on a single source of supply or a small number of preferred suppliers. The paper reconsiders procurement methods in terms of a continuum using the economics of transaction costs. The paper then illustrates the economic issues discussed by considering procurement in the defence sector. Defence is taken as an example of public procurement with experience and opportunities for competition, partnership sourcing and long-term buyer-supplier relationships. The paper concludes that the case for partnership sourcing over competition is not clear cut.     

GLOBAL PROCESS STANDARDIZATION: A CASE STUDY

Meeting the needs of customers has always been a challenge. It is even more so for suppliers who serve customers across the world, and where the customer expects standardized processes ‐ regardless of the country. While it is challenging to standardize critical processes in a domestic market, it is more challenging in the global, or transnational, market. This paper uses a case study to share how one organization was able to standardize their processes across the globe. Benefits derived from this effort are also provided. A framework for determining how key transnational processes can be managed and standardized is also presented.     

The role of Swedish retailers in food innovations

Innovations should create value for increasingly individualistic consumers with varying demands and for other stakeholders. Today, retailers have the power in the supply/value chain. This research investigates how Swedish food retailers view innovations, their role and that of customers and suppliers in the development process and how they see future development. The study is based on open-ended interviews. The results show that Swedish retailers regard food product innovations as something to provide to consumers rather than achieve with consumers. Retailers want more collaboration with packaging suppliers to differentiate. Retailers are successful in establishing their own brands, in becoming brands themselves and in competing with producer brands. This follows the UK model and may result in fewer alternatives in stores and fewer product – or new technology-based innovations by Swedish producers. Service innovations can still occur for retailers to retain consumer loyalty. Consumers demand more than new products; they want to be excited by the shopping experience. More innovations will require deeper insight about consumers, efforts from the value chain and from outsiders. Collaboration is needed to establish trust among supply chain actors.     

Customer Participation and Project Performance: The Mediating Role of Knowledge Sharing in the Chinese Telecommunication Service Industry

Purpose: Extant literature has devoted more attention to customer value co-creation and knowledge sharing, not only in business-to-customer (B2C) markets, but also in business-to-business (B2B) markets. This study explores and examines the antecedents and consequences of customer knowledge sharing in the context of B2B markets by applying the motivation-opportunity-ability (MOA) framework.

Methodology/Approach: This empirical study involves two structured surveys of project managers from both suppliers (n = 213) and customers (n = 312), which were conducted in the context of the Chinese telecommunication service industry. The conceptual model of this study was subsequently tested by developing Partial Least Squares (PLS) based structural equation models.

Findings: It was found that customer knowledge sharing is facilitated by four MOA factors: customer orientation, customer perceived benefits, customer socialization, and customer technological capability. It was determined that knowledge sharing has a direct and significant effect on project performance. Furthermore, the study revealed that such relationships vary across suppliers and customers.

Research Implications: This study extends the existing research stream of interfirm knowledge sharing by examining the antecedents and consequences of customer knowledge sharing from dual perspectives of customers and suppliers, and sheds light on the benefits of customer knowledge sharing. The dyadic perspective embodied in this design facilitates our understanding and management of knowledge sharing between organizations.

Originality/Value/Contribution: This article provides an important contribution to the existing literature of customer knowledge sharing by revealing how to effectively facilitate interorganizational knowledge sharing, particularly knowledge from customers to suppliers, and discovers conditions under which customers are more likely to exchange information, and share knowledge with their suppliers from the dyadic perspective.     

Social Sustainability in Selecting Emerging Economy Suppliers

Despite the growing public awareness of social sustainability issues, little is known about what drives firms to emphasize social criteria in their supplier management practices and what the precise benefits of such efforts are. This is especially true for relationships with international suppliers from the world’s emerging economies in Asia, Latin America, and Eastern Europe. Building on stakeholder theory, we address the issue by examining how pressures from customers, the government, and employees as primary constituencies of the firm determine the extent to which firms consider social aspects in the selection of emerging economy suppliers. Further, we analyze how such socially sustainable supplier selection relates to the capabilities of the firm’s suppliers, its market reputation, and the learning in its supply management organization. We test the developed research framework empirically using data from 244 U.S. and German corporations. Our findings, consistent with our hypothesized model, suggest that middle-level supply managers as internal stakeholders play a major driving role for firms’ socially sustainable supplier selection, and that strong positive links exist between that selection and the investigated outcomes.     

Supplier Role Conflict: An Investigation of Its Relational Implications and Impact on Supplier Accommodation

Existing research on supply chain relationships suggests that one of the underlying tensions between supply chain partners is that of opposing perspectives and goals in the customer?supplier relationship. In today's business world with requirements in constant flux, suppliers are often asked to accommodate “special” requests made by their customers, not part of the contractual agreement. Suppliers frequently fill requests to protect the relationship with the customer, even if they fall outside of what they consider their role as a supplier. Issues of supplier role conflict emerge when customers and suppliers have different views of what the supplier's role should entail. There is little research examining the potential for supplier role conflict in supply chains. Specifically, this research draws on literature from multiple disciplines to consider supplier role conflict that may stem from accommodation and the impact of this role conflict and supplier accommodation on the supply chain relationship and future accommodation behavior. Hypotheses are tested using two scenario‐based experiments. Results suggest that supplier adaptation and flexibility both have positive relational effects. If suppliers perceive accommodation requests as outside of their contracted role, supplier role conflict can have detrimental effects on the supplier's relationship perceptions and their willingness for future accommodation.     

The Impact of Key Retail Accounts on Supplier Performance: A Collaborative Perspective of Resource Dependency Theory

Existing literature suggests that the increasing concentration in the retail industry is allowing powerful retailers to exploit their weaker suppliers, which causes the suppliers’ performance to suffer. This study takes a collaborative perspective of resource dependency theory and suggests that when suppliers engage in supply chain relationships with key retail account (KRA) customers, their performance may improve, depending on the varying levels of the supplier's and KRAs’ market shares. The empirical analysis of data from two large retailers, Wal-Mart and Target, and a broad cross-section of their suppliers provides ample support for most of the hypotheses set forth in this paper: Suppliers that depend on KRAs for a significant share of their total revenues relinquish some of their leverage in the marketplace, but as the KRAs gain market share, their suppliers’ performance tends to increase. Cumulatively, these results provide evidence of collaborative supplier–KRA relationships, such that a supplier's dependency on KRAs may positively affect supplier performance. This finding supports a more positive, symbiotic view of dependency, resulting in important implications for key account management, supply chain management, and retail research and practice.     

Market orientation and uncertain supply in upstream markets: an exploratory study

A key task of the purchasing function is to secure adequate and timely supplies of necessary input factors. In some industries, however, this task is challenging, as it may be difficult to obtain timely and reliable input, e.g. in industries based on natural resources. This may have serious implications for firms’ ability to compete effectively in their output markets. Few empirical studies of purchasing behaviour have focused on how actors cope with uncertain supply. Also, the fast-growing market orientation literature generally seems to have neglected the importance of supply. This paper aims to provide insight into the poorly understood question of how upstream actors cope with uncertain input supply to handle customers’ needs and wants. To investigate our research problem an exploratory study was conducted among 20 upstream actors in the seafood industry. A quasi-experimental approach was applied by selecting firms from two industry branches so that one group was exposed to the “treatment” (i.e. uncertain supply) while the other group was not. Our findings show that when supply is uncertain it is of utmost concern and considered a key determinant in satisfying the firms’ target markets.
