THE RELATIONSHIP BETWEEN PURCHASING AND SUPPLY MANAGEMENT'S PERCEIVED VALUE AND PARTICIPATION IN STRATEGIC SUPPLIER COST MANAGEMENT ACTIVITIES

As firms have placed more emphasis on their core competencies and outsourced production and services to suppliers, effective cost management of purchases has become a critical factor in achieving corporate success. The Purchasing and Supply Management (PSM) function is generally responsible for obtaining goods and services from outside suppliers. Techniques such as total cost of ownership, supplier cost structure analysis, and target costing have become important tools for PSM to manage inbound supply costs. Results of a survey indicate that the perceptions of PSM by peer functions and top management, in terms of PSM's importance and accountability, are related to implementing the strategic cost management activities of total cost of ownership, supplier cost structure analysis, and target costing.

Responsible supply chain management in the Asian context: the effects on relationship commitment and supplier performance

Responsible supply chain management (SCM) in the era of expanding global sourcing can play a critical role in diffusing corporate responsible practices throughout the emerging Asian economies. Thus, this paper aims to examine how responsible SCM can contribute to supplier performance, including environmental, social and operational performances through the improvement of relationship commitment in the Asian context. The hypotheses of this study were tested with the data from 187 South Korean suppliers and 193 Vietnamese suppliers. The paper finds that responsible SCM enhances relationship commitment as well as improves the sustainability performance of suppliers in Asian countries. Relationship commitment plays a critical and mediating role in the relationships between responsible SCM and environmental, social and operational performances. This study also finds that there is a contextual difference between South Korea and Vietnam. The findings of this paper provide implications for supply chain members to integrate environmental and social issues into their SCM practices so as to foster stronger sustainability performance in the global supply chain.     

Unintended Consequences: How Suppliers Compensate for Price Concessions and the Role of Organizational Justice in Buyer‐Supplier Relations

“You get what you pay for” is one of life's lessons that predominates in purchasing decisions individuals make in their personal lives. The results of this study suggest this lesson should also prevail among management when price‐related purchasing decisions in businesses are being made. An evaluation of over 1,700 purchasing instances across seven years of a longitudinal panel data set collected from Tier 1 production suppliers to the six major North American automotive Original Equipment Manufacturers (OEMs), Chrysler, Ford, General Motors, Honda, Nissan, and Toyota, found that suppliers compensate for price concessions and price reduction pressure from the OEM in the year following the concession, by reducing product quality, service support, and R&D expenditures associated with goods provided to the OEM. This industry is particularly relevant because it is highly adversarial, yet at the same time reliant on interdependence. The results show that supplier price concessions granted to an OEM led to compensatory supplier behaviors of reduced quality and R&D expenditures toward that OEM. Further, the results suggest that the organizational justice dimensions of distributive justice, procedural justice, interpersonal justice, and informational justice can ameliorate negative supplier compensatory activities. A buyer–supplier relational environment that engenders organizational justice tactics such as open and honest communication with suppliers provides suppliers the expectation of an acceptable return on business over the long term, provides help to suppliers to reduce costs, and builds supplier trust of the OEM had generally positive effects on quality, service, and R&D expenditures. From a management perspective, these results indicate there is a very real risk versus reward issue associated with pressuring suppliers for price reductions.     

Environmental purchasing: a framework for theory development

This paper examines environmental research in the supply chain management literature in order to establish a framework for current and future development of environmental purchasing theory. As the purchasing function takes on a more strategic role in forming trading partnerships with others in their supply chains, it is in a critical position to influence responses to concerns about the natural environment. Definitions of environmental supply chain management and environmental purchasing are offered and the literature is reviewed. Linkages of environmental purchasing with transaction cost analysis are established and future research is described to enhance the study of purchasing's ability to effect the natural environment.     

Procurement commodity structures: issues,lessons and contributions

Little attention has been given in the literature on how to involve suppliers in technological development, especially from the purchasing organisation perspective. In researching how to involve the suppliers, we explore the purchasing structure, particularly the role-played by the “commodity managers”. The data for this exploratory study was collected through in-depth interviews and observations made in the case study Company (a global automotive OEM located in Europe) and two of its critical suppliers also located in Europe. The end result of this study is the development of a conceptual model for the organisation and management of purchasing projects in outsourced product development through commodity managers.     

Buyer/supplier partnering in British industry: The automotive and telecommunications sectors

Practitioners and academics in the fields of marketing and purchasing management share an interest in the effective management of inter‐firm buyer‐seller relationships. Buyer/supplier partnering has been advocated as an effective approach to the management of key customer or supplier relationships. Within both the automotive and telecommunications sectors of the British economy there is intense interest among major buying organisations in the development of durable partnerships with key suppliers. However, within both industries the major UK and American owned firms have to operate under the shadow of traditionally antagonistic relations with suppliers. The current state of buyer/supplier partnering within the two industries is evaluated within this historical context, and the key problem identified is the need to overcome antagonism within the inter‐organisational culture. The costs and benefits of partnering approaches to both marketing and purchasing are discussed, and implications for marketing managers seeking to develop partnerships with major customer organisations are outlined.     

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.     

Lean supply and price-based global sourcing — the interconnection

Just-in-time delivery, design for manufacturing, and early supplier involvement based on frequent and close interactions between buyers and suppliers are some of the basic conditions of lean supply in the automotive industry. Many of these conditions appear to be difficult to achieve in global purchasing. This is because global purchasing has mostly been seen as a means of putting price pressures on suppliers. The aim of this paper is to highlight the interconnection between global purchasing and lean supply. A strategic project “live or die” was chosen within a major global auto original equipment manufacturer (OEM) located in North America. To get as complete a picture as possible of the context and causal conditions, and to be able to make coherent benchmarks with objectives, global purchasing was followed across one major project rather than across different ones. The data was collected through interviews both in the OEM and in six suppliers and validated by triangulation and internal seminars. The analysis was done by screening data into some of the conditions identified in lean supply, which were observed to be the most relevant in the case company. We found that lean supply is affected negatively by global purchasing based on price and thus, price-based global purchasing should not be used for sourcing complex components that require early supplier involvement and intensive engineering collaboration between OEMs and suppliers. Instead, it could be proactively used in the sourcing of less complex modules and simple components.     

Implementing reverse e-auctions: A learning process

Reverse e-auctions, which enable suppliers to compete on-line in real-time, are changing the way organizations select their suppliers. We explore how five large firms in different industries learned to use e-auctions, and how e-auctions were integrated into their purchasing processes. To successfully implement e-auctions, organizations should: (1) build e-auction competencies; (2) organize for knowledge management; (3) create a holistic sourcing process; (4) focus on the total cost of ownership; and (5) experiment with e-auction designs. Key observations are drawn from the case studies, and implications for supply managers are presented.     

供应商数量对公司经营绩效的影响

如何对供应库进行优化日益成为企业的重大战略问题之一,而最常见的供应库优化的实践则集中于供应商数量。本文从交易成本、供应商响应度、供应风险和供应商创新等四个方面分析了供应商数量对公司经营绩效的影响,认为供应商数量与原材料存货管理的效率和公司总体经营绩效之间均成倒U形关系。当公司对大量供应商逐渐进行缩减时,交易成本和供应风险降低,同时,供应商的响应度和创新提高,由此导致其经营绩效的改善;但是,当供应商数量缩减到某一个点后,供应商数量的继续缩减则导致供应风险的增大和供应商创新的下降,从而导致其整体经营绩效的下降。     

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.     

Innovation sourcing excellence: Three purchasing capabilities for success

Innovation sourcing has become more critical across many industries. As global value chains have become more fragmented, change and opportunity comes from all sides. As a result, companies need to excel at capturing innovation opportunities with existing and potential supply chain members. This article describes a simple framework with three essential innovation sourcing capabilities needed to excel in purchasing: (1) Purchasing needs to explore unmet needs and anticipate future competitive advantages by working closely with other functions and clients; (2) it needs to explore external opportunities beyond first-tier suppliers; and (3) it needs to involve suppliers in innovation projects that consistently deliver results over time. Our framework has been developed based on a combined qualitative and quantitative research methodology that takes into account practices and results at the purchasing and company levels. The framework will help C-level managers and purchasing teams benchmark their progress in innovation sourcing and understand what steps need to be taken to achieve excellence.     

The role of buyer and supplier relationships in integrating TQM through the supply chain

Many academics and practitioners have alluded to the importance of total quality management (TQM) principles and the important role the purchasing function plays in the quality process. However, the role of the buyer–supplier relationship in the TQM process has not been directly investigated to any large extent. Three hypotheses concerning the role of buyer–supplier relationships in the success of TQM implementation were tested. The results demonstrate that buyer–supplier relationships are different in firms with successful TQM programs. Hypothesis 1 suggests that those firms with successful TQM programs will have more formal mechanisms for interacting with suppliers. The second hypothesis suggests that business units with more successful TQM programs exhibit a greater degree of competitive focus and single sourcing. The third hypothesis relates to a higher level understanding of internal and external customer needs by successful TQM adopters. All hypotheses were supported. The buyer–supplier relationships in firms with successful TQM programs are different than firms with less successful TQM programs.     

A survey of supply chain collaboration and management in the UK construction industry

The paper details the results of a questionnaire survey of supply chain collaboration and management in the top the UK construction industry contractors. The results indicate the formation of a significant number of partnerships/ collaborative agreements between contractors, suppliers and clients following the publication of the Latham (1994) and Egan (1997) reports. It appears that construction supply chain management (SCM) is still at its infancy but some awareness of the philosophy is evident. Contractors identified improved production planning and purchasing as key targets for the application of SCM in construction. Barriers to success included: workplace culture, lack of senior management commitment, inappropriate support structures and a lack of knowledge of SCM philosophy. Training and education at all levels in the industry are necessary to overcome these barriers.     

Small local firms inside the supply chain: Challenges and perspectives

The authors provide the results of an empirical research carried out in north-east Italy and completed in 1992, which was aimed at investigating the rapport between large manufacturers operating on the multidomestic and global markets and the small local supplying concerns. This research identifies that the globalization process has had a strong impact in the relations with suppliers. The purchasing firms have adopted a particular approach when selecting the suppliers. This has involved widening their previous geographic areas of contact, even making use of foreign sources. Consequently, the local micro units either will become excluded from future business relations with the purchasing organizations, or will be relegated into lower levels of the supply chain. Today small and very small units working as suppliers with direct link with large-scale clients, face many challenges: they should now renew their know-how and skills, develop a new managerial and organizational sense, and recognise the need to invest in new forms other than machinery and processes. The empirical study clearly showed both the limits and the structural weakness of such small units and provided some indications for growth in their technical-productive potential.     

An Empirical Study of Business-to-Business Electronic Marketplace Usage: The Impact of Buyers' E-Readiness

This study addresses critical questions regarding the extent of business-to-business electronic marketplace usage for purchasing, and the degree and impact of buyers' e-readiness on the range of electronic marketplace usage. The data from a Web-based survey of 359 purchasing professionals in the United States suggests that buyers with more experience in using information technology, the Internet to facilitate purchasing, and information systems for enhancing supply chain management would more likely use electronic marketplaces for purchasing. This study has significant theoretical implications because it confirms the important role of e-readiness in the electronic marketplace usage model. The practical implications of this study are also discussed.     

“Do frogs jump as a result of privatisation?” Impact of privatisation on buyer–supplier relationships

As the cornerstone of the Conservative Government between 1979 and 1996, privatisation has undoubtedly had an enormous impact on the UK economy. On the whole, privatised companies have improved their performance in an ever increasing competitive environment by focusing on, among other things, a drive to reduce costs through bought-out goods and services. Research into Japanese companies, meanwhile, has highlighted the key role that supplier relationships play in their success. It has stressed the advantages of co-operative over adversarial relationships with suppliers, and evidence shows that an increasing number of Western companies are adopting this practice. This has raised the profile of purchasing in these companies with a change towards `better practice’ and improved management of the supplier base. From this new research a model of Feature and Construct Evaluation and Aggregation (FCEA) has been developed, in the search for a link to support the proposition that privatisation has an influence on purchasing strategies concerning supplier relationships. The research has shown that only a very limited link exists. Whilst Purchasing as an activity has increased in its importance and control, it has not become strategic. Purchasing strategies have not evolved or supported the business strategy as a result of privatisation, nor does privatisation encourage the development of purchasing strategies towards closer relationships with suppliers. This is compounded by the EC Directives that reflect an `open tender’ model of procurement, particularly evident in the emphasis on formal competitive tendering procedures and maintaining an `arms-length’ relationship with suppliers.
