Supplier development and cost management in Southeast Asia—Results from a field study

This paper is about supplier development when international companies have production sites in Southeast Asia and look for opportunities to switch from international suppliers to local suppliers. We conducted a field study involving site visits to companies in Thailand and Vietnam, and interviews at corporate supply chain departments. Some key observations are: cost management was a dominant motive for taking local supplier development initiatives. Furthermore, local sourcing and local supplier development were important for international companies to improve access to local customer markets. Firms deliberately assessed whether a particular supplier would likely be able to improve sufficiently to warrant investing in supplier development, which typically involved a combination of initiatives, requiring the international firm to take considerable efforts. Local sourcing strategies and priorities for supplier development initiatives tended to focus on items with low supply risk and low volume. These findings are discussed based on transaction cost economics, and we suggest that firms use several ways to reduce the risk of transaction-specific investments in supplier development initiatives.     

Human resource barriers to partnership sourcing in China

Building on previous research on both buyer–supplier relations and human resource management in the PRC, interviews with managers in each of 47 UK-owned PRC subsidiaries were undertaken. The majority of firms are actively pursuing close and cooperative relationships with local suppliers, but there are substantial human resource barriers to the establishment of partnership sourcing arrangements. Grounded analysis reveals key HR barriers to partnership sourcing in the form of difficulties in staff recruitment and retention, problems in cross-cultural communication, poor working practices in supplier firms, and corrupt staff behaviour. This paper describes and analyses these problems, discusses measures that are being taken in an attempt to overcome the problems, and comments on the progress being made towards ‘ideal type’ partnership sourcing arrangements.

Co-alignment of supplier quality management practices and cognitive maps – A neo-configurational perspective

Much of the previous research on the ‘purchasing practice–performance link’ rests on the notion of “net effects,” which assumes that specific practices independently of each other impact outcomes. This study challenges this core tenet by adopting a neo-configurational perspective, exploring how different combinations of factors (called “configurations”) affect outcomes. Another limitation of extant studies on the ‘purchasing practice–performance link’ is the narrow focus on practices; more recent behavioral supply management research finds the behavior of managers to be critically influenced by cognitive maps—the lenses through which managers perceive, simplify, and interpret the world. Focusing on supplier quality as a core aspect of the broader ‘purchasing practice–performance link’, this study explores how configurations of different supplier quality management (SQM) practices and SQM-related cognitive maps help firms to manage supplier quality. It uses fuzzy-set qualitative comparative analysis (fsQCA) to identify SQM configurations and a cognitive-linguistic approach for the computerized text analysis of purchasing managers’ cognitive maps in the context of Western companies sourcing from Chinese suppliers. The configurational fsQCA analysis identifies four different configurations associated with overcoming barriers to SQM in emerging markets. SQM-related cognitive maps prove to be a critical component in these four configurations.     

The impact of sourcing enterprise system use and work process interdependence on sourcing professionals’ job outcomes

We examine sourcing professionals’ work context to conceptualize how they use sourcing enterprise systems (SESs) and to understand when SES use results in positive/negative job outcomes. We differentiate between SES use for supplier selection and supplier governance, identify sourcing professionals’ work process interdependence as a moderator for the impacts of SES use on job satisfaction, and suggest job satisfaction mediates the impacts of SES use on job performance. We conducted a field study of sourcing professionals’ SES use at one of the largest consumer product companies in the United States, which has implemented an SES to innovate its sourcing professionals’ work processes. Based on our analysis of the survey and qualitative data we collected, we found the impacts of both types of SES use (1) to be negative on job satisfaction when work process interdependence was high, (2) to be positive on job satisfaction when work process interdependence was low, and (3) to be mediated by job satisfaction for job performance. We discuss the implications of our findings for the literature at the intersection of information systems and operations management as well as for the information technology enabled innovation of sourcing processes and, more generally, complex business processes.     

Choosing between single and multiple sourcing based on supplier default risk: A real options approach

The selection of a given purchasing strategy is a central activity in risky environments. Single sourcing, a powerful approach in a stable environment, can amplify a firm's exposure to risk (e.g., supplier's default) in the presence of uncertainty. Multiple sourcing, however, presents higher costs due to the management of more than one supplier. A correct evaluation from a risk management perspective is needed. This paper proposes the Real Options approach for valuing the probabilistic benefits of multiple sourcing in managing the supplier default risk (to be compared with the related higher costs). A computational model, based on the Monte Carlo simulation, was developed. The results show the (probabilistic) advantages of adopting the multiple sourcing strategy in risky environments for a specific case. The proposed sensitivity analysis is aimed at identifying the impact of the most important transactional parameters on the differential benefits of the two sourcing strategies. Thus, the model and its managerial implications represent a valid support for the decision-making process in the presence of uncertainty.     

Sole sourcing,competitive sourcing,parallel sourcing: Mechanisms for supplier performance

Quality management practitioners in the USA such as W. Edwards Deming, strongly advocate the Japanese model of supplier relationships-recommending substantial specific investment in a single supplier for improved co-ordination and higher quality. But the strategy literature and conventional wisdom favor multiple sourcing, suggesting that a high level of specific investment in a sole source will lead to problems with supplier performance. Using agency theory, we construct a model to evaluate the tradeoff between the costs to set up and coordinate with suppliers and the incentive for performance provided by competition. We find that the validity of Deming's Point Four, that sole sourcing is more profitable than competitive sourcing, depends on parameters such as profit sensitivity to supplier performance.     

Cooperating and competing in supply networks: Making sense of a triadic sourcing strategy

This paper introduces the concept of a “triadic sourcing strategy”. Triadic sourcing is a way for buying companies to nurture and benefit from cooperation and competition between two suppliers with partially overlapping capabilities. In contrast to hybrid sourcing strategies outlined in the literature-parallel and network sourcing—the distinctive feature of triadic sourcing is that the buyer actively creates interdependencies between two suppliers. To illustrate this principle and the characteristics of triadic sourcing, Volvo Cars’ use of two suppliers of seats is described. The paper asserts that triadic sourcing is a dynamic sourcing strategy that contributes to efficiency and innovation for the buyer and the two suppliers, together forming a triad that is subject to firm interdependence and network embeddedness.     

Antecedents to supplier integration in the automotive industry: A multiple-case study of foreign subsidiaries in China

Supplier integration has become an important concept for improving supply chain performance. The aim of this paper is to identify factors that facilitate and inhibit supplier integration in the context of the Chinese automotive industry. An inductive approach based on grounded theory was chosen as the research methodology, where data was collected through 30 detailed case interviews with subsidiaries of foreign automotive companies operating in China. The results indicate that buyer-side leadership is an important antecedent for building motivation, trust, and commitment among suppliers and for shaping their mindsets. This, in turn, facilitates strategic alignment and enables suppliers to build collaborative capabilities, which are finally shown to be a key enabler for successful supplier integration.     

The benefits and constraints of temporary sourcing diversification in supply chain disruption and recovery

Sourcing diversification is the preferred hedge to supply chain disruption risks, but many companies insist on single-sourcing for long-term strategic benefits. For rare-but-catastrophic disruptions of fortified supply chains, temporary sourcing diversification has been seen as a desirable response strategy. However, little is known about the conditions to temporary sourcing diversification and the situations where it is applicable. Our fieldwork and comparison of two disaster recoveries at Aisin Seiki and Riken Corporation shows that while temporary sourcing diversification worked in the Aisin Seiki case, it was impossible at Riken due to the high degree of specificity required in the design and manufacturing methods of the disrupted product item, suggesting product and process specificity limits recovery alternatives. Unawareness of such constraints to temporary sourcing diversification may result in over-optimism regarding its feasibility and insufficient disaster preparedness. In addition, the case of Riken’s recovery from an earthquake in 2007 is systematically documented in this paper for the first time.     

考虑责任违规中断的负责任采购博弈

随着全球供应链的发展,供应商过程违规越来越成为供应中断的常见原因。为改善过程合规性,很多跨国公司已经在全球范围内,尤其是发展中国家实施负责任采购。针对供应商-采购方过程行为建模内生化责任违规中断风险,构建采购方和风险供应商之间的Stackelberg博弈模型,研究订货比例、成本结构等对决策产生的影响。通过比较静态分析发现,在责任违规中断风险下,即使跨国公司的订单占比较小,风险供应商也有动力不断提高合规水平直至完全合规。这说明跨国公司可通过游说当地政府提高对过程违规行为的监管和惩罚,以此激励风险供应商提高合规努力。     

Opportunism or strategic opportunity seeking? Three approaches to emerging country sourcing

The current interest in low-cost or emerging country sourcing (ECS) has inspired a multitude of empirical studies. These studies are based on varying methodological approaches and have come to somewhat different conclusions regarding the motivations for and outcomes of ECS. This paper argues that the overall approach to the new markets, especially the strategic network context surrounding each buyer-supplier relationship in the ECS setting, impacts on the prerequisites for success.The aim of the paper is to identify and discuss approaches to ECS. It begins with a review of recent empirical studies, scrutinising research interests and the approaches applied by the companies studied. It suggests and illustrates three broad categories of approaches: (1) the transactional approach focusing on individual sourcing in the emerging country, (2) the supply base approach focusing on establishing a set of supplier relationships in the emerging country, and (3) the network positioning approach in which both supplier and customer relationships are developed in the emerging country. The paper also discusses the three approaches as stages in an internationalisation process.The paper concludes that of the three strategic approaches the viability of two – the transactional approach and the supply base approach – can be questioned on several grounds, but that when seen as a process directed towards developing a network position in a new (emerging) market all three approaches make sense as different stages in a process moving towards achieving that goal. An explanation for the process of increasing commitment in emerging markets, relying on learning in interaction and on relational investments beginning with suppliers and continuing with customers, is also discussed.     

The moderating effects of supplier portfolio characteristics on the competitive performance impacts of supplier-facing process capabilities

We draw on the interorganizational relationship management literature to examine how contextual characteristics of the supplier portfolio (portfolio concentration, relationship length, and supplier substitutability) moderate the impacts of process alignment and partnering flexibility – two of a firm's key supplier-facing process capabilities to manage supplier relationships – on a product line's competitive performance. Our analysis of survey data on a firm's supplier portfolio for a major product line indicates that the impacts of process alignment and partnering flexibility on competitive performance are moderated by the three supplier portfolio characteristics. Specifically, while concentrated relationship portfolios, long-term relationships, and supplier substitutability amplify the positive effect of process alignment on competitive performance, concentrated relationship portfolios and long-term relationships attenuate the competitive benefits that firms derive from partnering flexibility. While long-term relationships and concentrated supplier portfolios enhance the competitive benefits of process alignment, operations managers also need to recognize the detrimental effects of these supplier portfolio characteristics on the competitive benefits of partnering flexibility.     

At the receiving end of supply network intervention: The view from an automotive first tier supplier

As companies are increasingly responsible for all ingredients that make up their products, the requirement to increase visibility and exert control over the entire supply network has been identified as key imperatives. However, little research to date has examined the consequences of supply network control on the suppliers that are at the receiving end of it. This paper reports on research into the dynamics of supply network intervention and the effects on the companies that are subject to attempts to control a supply network, particularly in the context of new product development. The paper discusses the case of an automotive component supplier and its role in a specific vehicle development project. The case study shows how the supplier was a victim of its customer's attempt to ‘supply chain manage’ the project, giving the supplier little control over key activities such as the choice of suppliers of key components and little influence on commercial and technical agreements. The perspectives of both vehicle manufacturer and supplier are debated to reveal the drivers for and problems associated with supply network intervention. The paper discusses the theoretical and managerial implications of the study and concludes by raising some serious questions about the negative effects of intervention strategies.     

Purchasing involvement in technologically uncertain new product development projects: Challenges and implications

This paper explores an emerging field of research within purchasing that concerns the changing role of purchasing when companies embark on technologically uncertain NPD projects. Where existing research has examined the role of purchasing in facilitating early supplier involvement in new product development, little research has been done to date on how purchasing's role might change when facing technologically uncertain NPD that require new capabilities and new technology. Based on an in-depth case study of a technologically uncertain NPD project in the passenger ship rescue equipment industry, the paper sheds light on how supplier involvement in NPD projects with a high degree of technological uncertainty impacts on a company's sourcing strategies and the challenges this poses for purchasing.Based on the case study findings, we propose a) that early purchasing involvement in technologically uncertain NPD projects requires a mature purchasing organization that possesses competences to interact effectively with R&D and b) that involving a new supplier from a different industry in NPD projects characterized by technological uncertainty requires a leap of faith from both innovating firm and supplier. The paper contributes to research in early supplier involvement in new product development, in particular the thin branch within this body of literature that now focuses on early purchasing involvement.     

Organisational design implications of global sourcing: A multiple case study analysis on the application of control mechanisms

Global sourcing has become an intended practice for many multinational corporations. Organisational design implications of global sourcing are rarely considered although they are one of the main facets of a global sourcing strategy. By elaborating on the information processing perspective of contingency theory, we derive explanations for the application of different control mechanisms in the global sourcing context. Our findings from case studies at eight multinational companies suggest that variations in control mechanisms can be explained by two contingencies: (1) corporate organisational structure and (2) the distribution of purchasing expertise among subsidiaries. Based on these case study findings, we formulate ten propositions for future research.     

A knowledge sharing framework for black,grey and white box supplier configurations in new product development

Managing supplier collaboration is increasingly cited as a key success factor in new product development (NPD) performance. Knowledge sharing between customer and supplier is a critical issue to manage collaboration but one which has only been partially investigated in the inter-organisational NPD context. This means that the specific characteristics of knowledge sharing according to the three classical supplier involvement configurations (black box: design is supplier driver, grey box: joint design and white box: design is customer driven) are still largely unknown. This research proposes to fill this gap by presenting a conceptual framework for knowledge sharing according to the supplier involvement configuration. Knowledge sharing integrates knowledge transfer, translation and transformation. A qualitative methodology based on cross-case comparisons of six projects in two companies is used. This research shows that the dynamics of knowledge sharing depend on each configuration. Thus, for black box projects, knowledge translation is a prerequisite for knowledge transfer. For grey box projects, knowledge transfer and translation are initiated simultaneously in a continuous loop. For white box projects, knowledge transfer is the key activity and potentially generates knowledge translation. The results suggest that managers should pay attention to translation activities which are critical for the success of co-development projects.     

Structural model for analysis of key performance indicators for sustainable manufacturer–supplier collaboration: A grey-decision-making trial and evaluation laboratory-based approach

With growing competition in the market and dire need for sustainability, it has become imperative for companies to build long-term relationship with their supply chain partners through sustainable collaboration. Among these, the supplier–manufacturer relationship is crucial for improved organizational, business and sustainable performance. Sustainable collaboration with suppliers involves crucial decision-making processes such as continuous supplier monitoring and supplier development. Hence, a critical challenge that a company faces is to identify the key performance indicators (KPIs) for assessing the performance of a supplier for sustainable collaboration. In this regard, this study focuses on identification of KPIs for an Indian home appliance company through exhaustive discussions involving multiple decision-makers. Further, a grey-based decision-making trial and evaluation laboratory (DEMATEL) model is proposed in the study for analysing the importance levels among the fifteen KPIs based on multiple stakeholder perspectives. The results of the grey structural model indicate seven KPIs as influencing KPIs and eight KPIs as influenced KPIs. The KPI ‘Information disclosure’ has been identified as the most influential KPI for the evaluation of suppliers for sustainable collaboration. The implications drawn from the result analysis model can provide meaningful insights to managers for identifying strategies towards strengthening the supplier–manufacturer relationship and achieving organizational and market competence.     

Sourcing Decisions with Capacity Reservations under Supply Disruptions

Firms employing both offshore outsourcing and nearshore sourcing strategies may face supply disruption, demand uncertainty, and quality risks simultaneously. Sourcing decisions become inevitably important and complicated when both profit and the customer-service level are taken into consideration. In this paper, we model a scenario where a manufacturer who faces stochastic demand procures major modules from an overseas supplier and two local suppliers. The overseas supplier offers quality products while being susceptible to disruption risks; if the local suppliers, who are completely reliable and serve as a backup, offer products that are of inferior quality, it may result in lower market acceptance and a bad experience for the final customers. The manufacturer has to reserve capacity with backup suppliers before urgent orders are placed, when the primary source experiences a shortfall. We explicitly derive the manufacturer’s optimal order quantities and reservation quantities, which are functions of the heterogeneous suppliers’ wholesale prices, reservation prices, and other parameters. The impacts of the fill-rate constraint and customer-experience quality constraint on the manufacturer’s purchasing decisions are investigated. Interesting managerial insights on the merits of backup sourcing with capacity reservations for managing demand uncertainties and supply disruption risks are also discussed.
