Barriers to the “key supplierization” of the firm

The phenomenon of key supply management (KSM) in business companies is far less investigated than the phenomenon of key account management (KAM) which beneficiates, both in practice and in an academic context, from a growing interest. This article is based on the empirical analysis of a sample of 10 international companies which have recently launched KSM programmes or are currently working on launching such programs. It examines the difficulties these companies come up against when implementing such programmes and proposes to organize these difficulties around three dimensions: 1) the difficulties in implementing real supplier portfolio approaches; 2) the narrow view of value co-creation with suppliers, and 3) the persistent lack of integration of the purchasing function with other internal functions within the company. The conclusion of the article is that KSM is far from being a mere symmetric phenomenon of KAM. Several implications are then discussed in relation to the implementation of KSM programmes within companies.     

Managing interdependencies in supplier networks

Building and managing a supplier base has been referred to in the literature as a key aspect of supplier management. Scholars have proposed a number of models aimed at enhancing the effectiveness of supplier network management, mainly based on a portfolio approach. In the IMP tradition of research, those models are often criticized as they ignore the interdependencies between the different existing dyadic relationships of a focal buyer company and its suppliers. Such interdependencies are the main focus of this paper, which has four objectives: (1) To analyze the types of relationships linking suppliers, (2) to understand the factors and dynamics underlying the creation and management of these relationships (3) to uncover existing links between buyer-supplier and supplier-supplier relationships, and (4) to clarify how different configurations of supplier relationship interactions impact on the performance of the actors involved. The paper discusses two empirical case studies, using the supplier networks of two focal buyer companies. We find that supplier interdependencies are mainly a by-product of the buyer-supplier dyads. Furthermore, the nature and dynamics of these dyads are a strong determinant of the scope and frequency of supplier connections and the corresponding effects on performance.     

Evaluating the bases of supplier segmentation: A review and taxonomy

A taxonomy of segmentation bases is presented which builds a multi-disciplinary approach to the categorization of suppliers. Supplier segmentation, from a purchasing perspective, still appears to be in the early stages of providing a coherent strategic intent behind supplier assessment. Whilst fragmentary in nature, current portfolio models are grouped into two principal taxonomic constructs of power and dependence and relational factors. In particular, the prevalent use of transaction cost economics (TCE) in portfolio modelling provides a foundation for purchasers to appraise risks from supplier opportunism. We augment existing approaches with reference to inter-organisational theory and the resource-based view to show different modes of inter-firm value creation that act as constituents of a strategic intent for segmentation. Our resulting taxonomy draws together a holistic view of supplier segmentation covering supply market conditions, product/service characteristics, supplier characteristics, buyer characteristics, and buyer-supplier relational factors.     

Power and interdependence in buyer supplier relationships: A purchasing portfolio approach

Power and interdependence are generally considered to be important concepts for understanding buyer-supplier relationships. Yet, empirical research on power and interdependence in buyer-supplier relationships is still limited. Power and interdependence issues also play an important role in Kraljic's portfolio approach, which is increasingly used by purchasing practitioners for managing different supplier relations and developing appropriate purchasing strategies. In this paper, the concepts of power and interdependence have been quantified for each quadrant of the Kraljic portfolio matrix, using data from a comprehensive survey among Dutch purchasing professionals. Several hypotheses have been tested and the findings largely confirm the theoretical expectations. The observed supplier dominance in the strategic quadrant of the Kraljic matrix is a notable finding, which indicates that even satisfactory partnerships are dominated by the supplier. Therefore, the presumed power symmetry of buyer-supplier relationships in the strategic quadrant seems no longer valid.     

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.     

Customer attractiveness,supplier satisfaction and preferred customer status: Introduction,definitions and an overarching framework

Industrial markets are frequently characterized by an oligopolistic market structure. As a result, suppliers may become highly selective with respect to decisions that involve collaborating with certain customers. Buying firms must therefore be more attractive than their rivals to obtain opportunities to collaborate with these selective suppliers. This apparently counterintuitive inversion of the classical marketing approach (that is, relationships that involve buyers competing for suppliers rather than the other way round) constitutes the foundation of the special issue that is introduced in this paper. In this paper, we present key terms and propose a model of preferred customership that uses a social exchange perspective to link customer attractiveness, supplier satisfaction and preferred customer status. The papers that contribute to this special issue are introduced within the context of this framework. Finally, this paper concludes with suggestions for future research directions.     

Collaboration and technology linkages: a strategic supplier typology

This study uses frameworks from the strategic management and operations strategy literatures to explore the relationships among collaboration, technology, and innovation in small and medium‐sized manufacturers. Statistical analysis of the responses of 200 New Hampshire manufacturing companies in four SIC code industries (fabricated metals, industrial equipment, electrical and electronic equipment, and instruments) leads to the development of a strategic supplier typology which is useful in explaining the differences in the composition and performance of various types of suppliers.

Configuring quality management and marketing implementation and the performance implications for industrial marketers

This study empirically examines if different configurations of quality management and marketing (Q&M) implementation exist in various industrial organizations and explores their implications for firm performance. We survey 304 organizations that have operational quality management systems and conduct in-depth interviews with selected groups of respondent organizations to understand their market-oriented behaviors. We perform cluster analysis of the survey data to empirically construct taxonomic configurations of Q&M implementation that may exist in these organizations. The results show three distinct configurations with each configuration displaying specific implementation characteristics. We label the corresponding organizations as reactive firms, progressive firms, and proactive firms, respectively. In other words, each configuration represents a different extent of implementing Q&M in organizations. We also find that the empirically-derived configurations, corroborated with in-depth interview data, are associated with various firm performance measures. The analysis reveals that proactive firms in which Q&M are implemented at a high level attain the best firm performance. Despite the exploratory nature of this study, the taxonomy developed yields valid and reliable findings that have significant theoretical and practical implications for industrial marketers.     

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.     

The effects of customer and supplier involvement on competitive advantage: An empirical study in China

The focus of this paper is on the effects of customer and supplier involvement on competitive advantage in the firm. Using the resource-based view and knowledge-based view of the firm, hypotheses are developed concerning customer involvement, supplier involvement, and competitive advantage. Hierarchical multiple regressions are employed to test the hypothesized relationships. The data used was collected from 139 Chinese manufacturing firms across different industries. Each variable except control variables in the model is measured by a number of scale items. Both reliability and validity (content validity, convergent validity, and discriminate validity) are demonstrated. The results of the regression analysis show that (1) customer involvement has positive impact on product quality, delivery reliability, process flexibility, and customer service; and (2) supplier involvement leads to decreased cost. These findings are interpreted in the context of Chinese manufacturing setting and enhance the understanding of the roles of customer and supplier involvement in China's business environment.     

From complexity to transparency: managing the interplay between theory, method and empirical phenomena in IMM case studies

Theory, method and empirical phenomena are the three cornerstones of research. In this paper we contemplate the interplay between them when case research in industrial marketing is concerned. Developments in research depend on what empirical phenomena we are able to capture, how theories are developed to understand and explain these phenomena and what methods we use and/or develop in the process. While the emphasis is often put on one of these aspects alone, this paper focuses on the links and interplay between theory, case method and empirical phenomena in the development of research in industrial marketing. Specifically, we seek to provide common ground between orthodox (deductive) and unorthodox (abductive) approaches to managing the interplay by making a pragmatic call for transparency in research procedures. In this endeavour we use the papers included in this special issue as examples of various aspects of this interplay. We conclude by suggesting that there is a gamut of approaches possible to case research in industrial marketing, each with its specific links to theory and empirical phenomena, and that this is promising for the development of research in the field, as long as it helps reduce, rather than increase, the complexity of the case studied.     

Configuring the after-sales service supply chain: A multiple case study

After-sales service in firms manufacturing and selling durable goods has a strategic relevance in its potential contribution to company profitability, customer retention and product development. This paper addresses the configuration of the after-sales supply chain. Three configuration choices are analysed: The degree of vertical integration, the degree of centralisation, and the decoupling of activities (i.e. how activities are decomposed and separated organisationally). Exploratory case study research was performed over seven companies belonging to durable consumer goods industries. The empirical findings show that configuration choices vary, suggesting that no “one best way” exists. Moreover, many firms develop multiple configurations. Choices are influenced by drivers, including the attractiveness of the after-sales business, the strategic priorities, the characteristics of the physical product and the services offered, and the configuration of the manufacturing and distribution supply chain. The paper discusses how these drivers may lead to consistent configuration choices, and how choices are related.     

Exploring the impact of a supplier portal on the buyer-supplier relationship. The case of Ferrari Auto

This article concentrates on the relationship between companies and their suppliers with a specific focus on the impact that information and communication technologies (ICTs) have on industrial (business to business) purchasing processes. After reviewing the extant literature, we classify the potential impact of ICTs on the buyer-supplier interactions into three main categories, i.e. impact on buyer-supplier relationship, impact on purchase process efficiency and impact on logistics process performance. Whilst scholars generally agree on the impact ICTs may have on buyer-supplier exchanges, they have not investigated concurrently all of these three impacts to understand their comparative relevance and the context in which this comparative relevance may change. In order to redress this gap in the literature our research study focuses on a particular form of ICT solution - supplier portals - and takes a supplier (rather than buyer) perspective. We explore empirical evidence from a single customer-multiple supplier case study, that of the Ferrari Auto supplier portal. Our study leads us to contend that suppliers view such portals as offering far more significant benefits to their relationship with customers than to the improvements in purchase process efficiency or to the performance of buyer-supplier logistics processes. We conclude with a short discussion of the main managerial implications and suggestions for future research.     

Reconfiguring supplier relationships between local and global: History matters

Small and medium-sized companies are increasingly facing international markets as part of their processes of growth and development. A great deal of literature deals with different patterns of growth and international development that are specific to SMEs with respect to large companies. Fewer studies have been conducted on the reconfiguration of company supplier relationships involved in these processes. This paper focuses on the role played by the consolidated set of company supplier relationships when the firm faces some critical stages in its process of development, i.e., growth from small to mid-sized and the implementation of new ventures abroad accessing new business relationships with international suppliers. A multiple and longitudinal case study shows how the local set of supplier relationships of four mid-sized Italian mechanical companies acting in industrial districts has played an important role in shaping the emerging set of supplier relationships and addressing companies' actions in their growth and internationalization processes.     

Applying activity-based costing in a supply chain environment

Traditional intra-firm cost accounting tools are not appropriate in the context of supply chain management, as there are no standards for the definition and composition of costs. This prohibits exchange and comparison of cost data among different supply chain members. Against this background, several activity-based costing models for inter-firm cost accounting have been proposed. Evaluating these models, a conceptual framework for activity-based costing in a supply chain has been developed. This also forms the basis for a single case study conducted at Europe's largest company for façade components. This demonstrates how significant inter-firm cost saving opportunities can be identified and offers a first step in assessing the suitability of the proposed model.     

Involving the process dimensions of time in case-based research

The lack of consideration of process dimensions of time in business marketing and management literature in general and in B2B case-based research in particular is in sharp contrast to the importance of time in our society. Marketing scholars need a stronger involvement of time to enrich case study research. This paper offers a structure and a set of questions on critical elements of time and presents a review of the debate on and treatment of time in management and (case-based) marketing science. Based on case-based articles in Industrial Marketing Management and the Journal of Business and Industrial Marketing (2004-2006), a content analysis of seven process dimensions is presented that reveals a limited presence of time aspects. Our findings indicate that case studies can benefit from an explicit incorporation of time and its different dimensions. While often only steps or stages are described and references to the flow of time are made, richer case studies also include the dimensions of duration, timing, frequency, pace and order. That way business marketing researchers will be able to deepen their case observations thereby increasing their learning.     

Developing theory from strategic management research in China

What are the main approaches to theory development based on strategic management research in China? What are some of the recent efforts in developing theory in this area? What is our recommended approach? To address these questions, this article outlines the three approaches to theory development in China research, articulates the Chinese context within the global economy, and highlights two streams of recent work as examples of following the recommended, integrative approach to theory development.     

The drivers of customer attractiveness,supplier satisfaction and preferred customer status: A literature review

In this paper, we focus on the preferential treatment of buyers by their suppliers. As there is a lack of detailed information regarding the reasons that suppliers serve some buyers better than others, our research addresses a supplier's evaluation of customers and how this evaluation can be influenced by buyers. To give an overview of the drivers of preferential treatment by suppliers, the provided literature review covers three research fields that are considered crucial to this issue: (i) customer attractiveness, (ii) supplier satisfaction and (iii) preferred customer status. By integrating these research topics, we provide a state-of-the-art analysis and overview of the various drivers of preferential treatment, build a preliminary conceptual model and suggest several directions for future research. The identification of the drivers and the resulting conceptual framework can serve as a stepping stone for additional research in this new field.     

Bridging the chasm between survey and case study research: Research methods for achieving generalization, accuracy, and complexity

This article describes how behavioral science research methods that management and marketing scholars apply in studying processes involving decisions and organizational outcomes relate to three principal research objectives: fulfilling generality of findings, achieving accuracy of process actions and outcomes, and capturing complexity of nuances and conditions. The article's unique contribution is in advocating and describing the possibilities of researchers replacing Thorngate's (1976) “postulate of commensurate complexity” - it is impossible for a theory of social behavior to be simultaneously general, accurate, and simple and as a result organizational theorists inevitably have to make tradeoffs in their theory development - with a new postulate of disproportionate achievement. This new postulate proposes the possibilities and advocates the building and testing of useful process models that achieve all three principal research objectives. Rather than assuming the stance that a researcher must make tradeoffs that permit achieving any two, but not all three, principal research objectives as Weick (1979) clock analogy shows, this article advocates embracing a property space (a three-dimensional box rather than a clock) view of research objectives and research methods. Tradeoffs need not be made; having-your-cake-and-eating-it-too is possible. The article includes a brief review of principal criticisms that case study researchers often express of surveys of respondents using fixed-point surveys. Likewise, the article reviews principal criticisms of case study research studies that researchers who favor the use of fixed-point surveys express.
