The relationship between supplier management and firm's operational performance: A multi-dimensional perspective

This paper presents an empirical study on the multidimensional relationships between supplier management practices and firm operational performance. Specifically, we focus on three supplier management practices, namely strategic long-term relationship, supplier assessment, and logistics integration, and test their effects on four operations performance measures, namely quality, delivery, flexibility, and cost. We use data collected from 232 manufacturing firms in Australia to conduct the study. Ten hypotheses were tested simultaneously using Structural Equation Modeling (SEM) technique. The results show that different supplier management practices have different unique effects on different operations performance measures. Supplier assessment has a positive relationship with quality performance. Both strategic long-term relationship and logistics integration have positive relationships with delivery, flexibility, and cost performance. From a theoretical perspective, this study demonstrates the relative contributions of different kinds of resources (i.e., supplier management practices in our case) to different performance measures. Our research findings provide practical insights for managers to understand the effectiveness, as well as the limitations, of different supplier management practices in enhancing different operations performance measures of firms.

Supplier relations and management: A survey of Japanese,Japanese-transplant,and U.S. auto plants

This article presents the results of a questionnaire survey sent to a sample of automobile manufacturers in the United States and Japan (including Japanese-managed plants in the United States) during the spring of 1990. The data support observations that Japanese and U.S. practices tend to differ in key areas and Japanese suppliers perform better in dimensions such as quality (defects) and prices (meeting targets, reducing prices over time); and that Japanese-managed auto plants established in the United States have, in general, adopted Japanese practices and receive extremely high levels of quality from Japanese as well as U.S. suppliers. These findings provide evidence that Japanese practices and performance levels are transferable outside Japan and suggest that considerable improvements are possible for U.S. suppliers supplying U.S. auto plants. In addition, the survey indicates that U.S. firms have adopted at least some practices traditionally associated with Japanese firms, apparently reflecting some convergence toward Japanese practices and higher performance levels in supplier management.     

Quality management practices and competitive performance: Empirical evidence from Japanese manufacturing companies

This paper presents the results of an empirical study on the relationship between quality management practices and competitive performance in Japanese manufacturing companies. The data was gathered from two surveys including the common sample of twenty-seven Japanese manufacturing companies in the 1990s and the 2000s. Statistical techniques are used to compare the degree of implementation of the eleven quality management practices and their impact on different dimensions of competitive performance between two periods. Findings of this study highlight the stability and consistency of the Japanese quality management, which can be used as one of the strategic weapons for maintaining competitive advantage of Japanese manufacturing companies.     

Strategic relationships between boundary-spanning functions: Aligning customer relationship management with supplier relationship management

This review focuses on the potential impact of enhanced strategic relationships between the boundary-spanning functions in supplier organizations. Specifically, the concern is with alignment between the organizational groups managing: marketing, sales and strategic account management; purchasing and supply strategy; and, collaborations and external partnerships. The topic is framed by the organizational evolution being driven by market change, and the search for superior innovation capabilities and business agility. These changes bring new challenges in cross-boundary integration and managing complex market networks. The logic is that strategic external relationships (with customers, supplier and partners) should be mirrored in strategic internal relationships (between the functions with lead responsibilities for managing relationships with customers, supplier and partners). Approaches to enhancing this capability include process management, internal partnering strategies and internal marketing activities. The discussion identifies a number of implications for practice and new research directions.     

Building capabilities via suppliers' effective management of relationships

This paper is an empirical study identifying the role of a relationship-specific capability of building capabilities through relationships (CBC) when suppliers put efforts into increasing their perceived market effectiveness by managing the effects of relationship quality. The relationship between relationship quality and effectiveness is mediated by CBC. Suppliers in a supply chain form different levels of relationship quality with partners in response to market conditions and industry characteristics. Relationship marketing by suppliers requires a deep understanding of the role of CBC that is developed by a supplier and an effective utilization of CBC to lead an effective relationship to better outcomes. This leads to maximizing of the competitive advantages for suppliers and will help maintain effective relationships.     

Managing customer relationships: Account manager turnover and effective account management

Managing relationships with customers and clients is a critical task for industrial sales organizations. This paper reports on research that focuses on improving client relationships through effective handling of account manager turnover and improved account management. Even in situations where account manager turnover is high, the relationship between the company and the SME client does not suffer if the account management turnover process is well managed. When account manager turnover is not well managed, customer satisfaction suffers. The research also identifies eleven specific management activities that are highly related to supplier satisfaction with both the account manager and the supplier financial institution.     

Relationship keyness: The underlying concept for different forms of key relationship management

For companies, relationships with external actors may constitute intangible assets. Many firms have put in place key account management programs in order to pay sufficient attention to strategically important customers and the marketing literature has studied such programs. However, a company's relationship portfolio also comprises relationships with other types of actors. The objective of this paper is to show that - across the different types of external relationships a company may develop - some relationships have more importance than others and, hence, are key. The authors argue that, as a consequence, the keyness of certain relationships has led to the emergence of approaches which can be referred to as key relationship management. For this purpose, the authors first present empirical material on the management of relationships between companies and their partners in strategic alliances from the French IT sector. They then discuss the concept of keyness as well as the common characteristics of different forms of key relationship management such as key account management, key supplier management and strategic alliance management.     

Making partner relationship management systems work: The role of partnership governance mechanisms

While the adoption of Partner Relationship Management (PRM) systems by suppliers to manage and monitor its network of partners (i.e. resellers) has been on the rise, the performance improvements have not been consistently realized. Governance theory suggests this may be due to how the PRM system builds on the mechanisms employed by the supplier to oversee their partners. This study investigates how the two capabilities of PRM systems (relationship and fulfillment capabilities) and two partnership governance mechanisms – formal (certification control) and informal (service support) – reinforce each other. These are then related to partner performance in terms of trust, commitment and customer satisfaction. Analysis of data collected from 192 partners in the information and communications technology (ICT) sector suggest a complex relationship. In terms of direct effects, a relationship capability increased trust yet, surprisingly, a fulfillment capability reduced commitment. In terms of moderating effects, certification control weakened the positive link between the relationship capability and performance. Service support, on the other hand, negated some of the detrimental impact of the fulfillment capability on performance. The results suggest the need of to tailor PRM systems in response to the specific performance expectations around them as well as a need to clearly understand how existing partnership governance mechanisms employed by the supplier will affect the performance of these systems.     

Gaining from vertical partnerships: knowledge transfer,relationship duration,and supplier performance improvement in the U.S. and Japanese automotive industries

We study sources of operational performance improvement in supplier partnerships. We argue that supplier performance will benefit most where time‐bound relational assets have developed between a buyer and supplier and the firms exploit the resulting communication efficiency by transferring productive knowledge. We examine the effects of two forms of knowledge exchange together with the prior duration of the buyer–supplier relationship. We find similar interaction patterns in two survey samples of Japanese and U.S. automotive suppliers. The effect of ordinary technical exchanges on supplier performance improvement does not vary with relationship duration. The effect of higher‐level technology transfer, however, grows more positive as relationship duration increases. Other results show relevant contrasts consistent with heterogeneous sourcing behavior between the two countries. The findings highlight the role of relational assets and show that it is important to distinguish between simple techniques and higher‐level technological capabilities when studying interfirm relationships. This research extends the literatures on knowledge transfer, buyer–supplier partnerships, and the performance dynamics of interfirm and intrafirm relationships in general.

Cooperation with international NGOs and supplier assessment: Investigating the multiple mediating role of CSR activities in SMEs

Nontraditional supply chain stakeholders, such as non-governmental organizations (NGOs), may be able to affect the adoption of CSR practices in supply chains. However, little is known about how companies cooperate with international NGOs to handle supplier assessment. Using partial least squares structural equation modelling, we establish a parsimonious model that links cooperation with international NGOs to supplier assessment through three CSR dimensions: economic, environmental and social. Data collected from eight thousand SMEs in the transportation industry generally support the hypotheses. Moreover, our findings reveal that SMEs' size matters in the relationships between cooperation with international NGOs, CSR practices, and supplier assessment. Overall, this paper provides unique insights into the role that SME CSR activities play in the relationship between cooperation with international NGOs and supplier assessment.     

Help or Hindrance? Causal Ambiguity and Supplier Involvement in New Product Development Teams

Suppliers are increasingly being involved in interorganizational new product development (NPD) teams. Successful management of this involvement is critical both to the performance of the new product and to meeting the project's goals. Yet the transfer of knowledge between buyer and supplier may be subject to varying degrees of causal ambiguity, potentially limiting the effect of supplier involvement on performance. Understanding the dynamics of causal ambiguity within interorganizational product development is thus an important unanswered empirical question. A theoretical model is developed exploring the effect of supplier involvement practices (supplier involvement orientation, relationship commitment, and involvement depth) on the level of causal ambiguity experienced within interorganizational NPD teams, and the subsequent impact on time to competitor imitation, new product advantage, and project performance. The model also serves as a test of the paradox that causal ambiguity both inhibits imitation by competitors, but adversely affects organizational outcomes. Survey data collected from 119 research and development‐intensive manufacturing firms in the United Kingdom largely support these hypotheses. Results from structural equation modeling show that supplier involvement orientation and long‐term relationship commitment lower causal ambiguity within interorganizational NPD teams. The results also shed light on the causal ambiguity paradox showing that causal ambiguity during interorganizational NPD decreases both product and project performance, but has no significant effect on time to competitor imitation. Instead, competitor imitation is delayed by the extent to which the firm develops a new product advantage within the market. A product development strategy based upon maintaining interfirm causal ambiguity to delay competitor imitation is thus unlikely to result in a sustainable competitive advantage. Instead, managers are encouraged to undertake supplier involvement practices aimed at minimizing the level of knowledge ambiguity in the NPD project, and in doing so, improve product and project‐related performance.     

Distributors' customer-driving capability under supplier encroachment

Suppliers in business-to-business (B2B) markets often directly approach end customers in addition to using third-party distribution channels. This phenomenon, known as supplier encroachment, poses an increasing challenge to the distributor's profitability in the supply chain. However, little research has adopted the distributor's perspective to examine how it can overcome this challenge. This study addresses this gap by adopting the dynamic capability and network embeddedness theory to postulate the critical role of the distributors' customer-driving capability in tackling encroachment. Using survey data from 125 distributor firms in the semiconductor industry, we show that distributors' customer-driving capability significantly improves firm performance and that the impact strengthens when supplier encroachment is high. Moreover, we delineate the positive impacts of supplier relationship exploration, distributor relational embeddedness, and customer service excellence on distributors' customer-driving capability. Interestingly, supplier encroachment weakens the effects of supplier relationship exploration and customer service excellence but strengthens that of distributor relational embeddedness, indicating the importance of leveraging peer relationships under high supplier encroachment.

The relationship between buyer and a B2B e-marketplace: Cooperation determinants in an electronic market context

“Stop thinking like a supplier and start thinking as a customer.”

The authors argue that cooperation may be achieved by augmenting the core product with technology-based services. Given the growing importance of real time information exchange and interactivity, a better understanding of the use of technology to the establishment and development of the buyer-supplier cooperative relationships is essential for knowledge advancement. This paper argues that firms should aim to put themselves into their customers' shoes and use the “voice of the customer” to take their major relationship management decisions. To do so, the authors use a sample of nearly 400 SMEs' purchasing managers, to better understand cooperation determinants from the buyers' perspective. The study reveals that in an electronic marketplace, cooperation is positively affected by termination costs, supplier relationship policies and practices, communication and information exchange, and negatively affected by product prices and opportunistic behavior. Moreover, both relationship commitment and trust play a major role in mediating the relationships between these five determinants and cooperation. Surprisingly, resources relationship benefits do not show a significant impact on either commitment or cooperation. Theoretical and managerial implications of these findings are discussed.     

Coopetition strategy as interrelated praxis and practices on multiple levels

Existing research often considers coopetition as something occurring between organizations on a meso level, that is, a relational or company level. This study explores coopetition strategy in the form of activities from a multilevel perspective. The focus is on coopetition praxis and practices and how these are interrelated on the micro, meso and macro levels. In order to improve our understanding of coopetition activities, we use the strategy-as-practice approach and integrate it with coopetition research. The empirical part of this study is based on a single qualitative case study of a coopetitive relationship between a large multinational company and its supplier. The findings show how praxis on the micro level influences, and is influenced by, practices on the meso and macro levels. Coopetition strategy is shaped over time through the relationship between praxis and practices on different levels. Our study contributes to coopetition research by focusing on coopetition strategy as something that is implemented on multiple levels, including the individual (micro) and network (macro) levels alongside the meso level.     

The Chinese paradigm of global supplier relationships: Social control,formal interactions and the mediating role of culture

This paper reports the results of a study that examined how firms can establish successful business relationships with Chinese suppliers. Its aim is to explore salient characteristics of the nature of buyer supplier relationships with the emergence of China as a dominant economic power. Two surveys have been conducted that investigated several factors that inhibit and enable effective supplier relationship management (SRM) between organisations sourcing from China and Chinese suppliers, and explored the impact of cultural characteristics of Chinese management on the nature and performance of supplier relationships. The research highlights the importance of the social control aspect of governance structure of supplier relationships and stresses that both social and formal control mechanisms should be implemented for more effective relationships with Chinese suppliers. It also demonstrates the need for companies to recognise the importance of guanxi and several cultural characteristics of the Chinese style of management in SRM and advocates the need for the development of a hybrid Sino-Japanese and global supplier relationship management paradigm that incorporates elements from the existing SRM models. It generates insights into how the cultural context of emerging markets affects the nature of business relationships and generates a research agenda in the field of supply chain management that can explore the development of new paradigms in supplier relationships management. The main theoretical argument put forward centres on the need for the development of a new global supplier relationship management paradigm that will take into account the cultural elements of the Chinese society.     

Power,buyer trustworthiness and supplier performance: Evidence from the Armenian dairy sector

The paper presents a Multiple Indicators and MultIple Causes (MIMIC) model for explaining the relationships between buyer-seller power, buyer trustworthiness and supplier satisfaction / performance. The model draws on an organizational supply chain perspective of power and is verified using data relating to dairy farmers’ relationships with their main buyer in Armenia. The analysis indicates that buyers are more trustworthy where there is greater competition for supplies. Buyer trustworthiness is also positively correlated with both the size of a supplier, as well as a supplier being a member of a marketing cooperative. Buyer trustworthiness has a positive impact on suppliers’ satisfaction (regarding their relationship with their main buyer) and enhances the quality and quantity of suppliers’ output.     

SPECIALIZED SUPPLIER NETWORKS AS A SOURCE OF COMPETITIVE ADVANTAGE: EVIDENCE FROM THE AUTO INDUSTRY

This study examines the relationship between interfirm asset specificity and performance in the auto industry. More specifically, I examine the extent to which differences in supplier–automaker asset specialization may explain performance differences between Japanese automakers (Nissan and Toyota) and U.S. automakers (Chrysler, Ford, General Motors). The findings indicate a positive relationship between supplier–automaker specialization and performance. In particular, the data suggest a positive relationship between interfirm human asset cospecialization and both quality and new model cycle time. Moreover, site specialization is found to be positively associated with lower inventory costs. The findings suggest that in the auto industry a tightly integrated production network characterized by proximity and a high level of human cospecialization will outperform a loosely integrated production network characterized by low levels of interfirm specialization.
