Managing Supplier Involvement in New Product Development: A Multiple‐Case Study*

Existing studies of supplier involvement in new product development have mainly focused on project‐related short‐term processes and success factors. This study validates and extends an existing exploratory framework, which comprises both long‐term strategic processes and short‐term operational processes that are related to supplier involvement. The empirical validation is based on a multiple‐case study of supplier collaborations at a manufacturer in the copier and printer industry. The analysis of eight cases of supplier involvement reveals that the results of supplier–manufacturer collaborations and the associated issues and problems can best be explained by the patterns in the extent to which the manufacturer manages supplier involvement in the short term and the long term. The results of this study reveal that the initial framework is helpful in understanding why certain collaborations are not effectively managed yet conclude that the existing analytical distinction among four different management areas does not sufficiently reflect empirical reality. This leads to the reconceptualization and further detailing of the framework. Instead of four managerial areas, this study proposes to distinguish between the strategic management arena and the operational management arena. The strategic management arena contains processes that together provide long‐term, strategic direction and operational support for project teams adopting supplier involvement. These processes also contribute to building up a supplier base that can meet current and future technology and capability needs. The operational management arena contains processes that are aimed at planning, managing, and evaluating the actual collaborations in a specific development project. The results of this study suggest that success of involving suppliers in product development is reflected by the firm's ability to capture both short‐ and long‐term benefits. If companies spend most of their time on operational management in development projects, they will fail to use the leverage effect of planning and preparing such involvement through strategic management activities. Also, they will not be sufficiently able to capture possible long‐term technology and learning benefits that may spin off from individual projects. Long‐term collaboration benefits can only be captured if a company can build long‐term relationships with key suppliers, with which it builds learning routines and ensures that the capability sets of both parties are aligned and remain useful for future joint projects.     

Problem solving in the upgrading of product offerings — A case study from the steel industry

This paper deals with the efforts of suppliers to upgrade their offerings — from standardized products to more advanced and customized solutions. Upgrading requires what has been identified in product development research as ‘problem-solving’ ability on the part of the supplier. The purpose of the paper is to explore the role of problem solving in the three phases of the upgrading process identified in the analytical framework: evaluation, transition, and post-implementation.Owing to the exploratory nature of this research a case study approach is used, describing and analyzing the implementation of two upgraded offerings of a steel company. The study illuminates the problems associated with such changes attributable to interdependences in the customer's current resource set up. The problem-solving ability of the supplier is a key capability in these efforts, also involving resource contributions from the buyer and other network actors.     

A transition from goods-dominant to service-dominant exchange logic in a B2B relationship: A relationship positioning perspective

The study complements the dominant interpretations of positioning in marketing management research by introducing a relational perspective on positioning in the industrial markets. Instead of focusing on products, brand, or company image only, the study focuses on the exchange logic of the relationship. The study suggests that exchange logic of the relationship i.e. relationship logic comprises a fundamental unit of positioning in the industrial markets. Accordingly, the study defines that relationship logic stems from the dynamics of the action, structural and management dimensions that integrate the buyer and supplier organizations into their mutual relationship. Through a longitudinal empirical study of a relationship between buyer and supplier companies in the food service industry, we show how the relationship has been repositioned from goods-dominant to service-dominant relationship logic. The results reveal elements on the action and structural dimensions, their mutual dynamics and managerial reframing actions that catalyze changes in the relationship logic, i.e., reposit the relationship. The results are organized into a framework that delineates the relationship positioning dimensions, and discusses the implications of such relationship positioning to guide further academic research and managerial practice.     

A Model of Supplier Integration into New Product Development*

In many industries, firms are looking for ways to cut concept‐to‐customer development time, to improve quality, and to reduce the cost of new products. One approach shown to be successful in Japanese organizations involves the integration of material suppliers early in the new product development cycle. This involvement may range from simple consultation with suppliers on design ideas to making suppliers fully responsible for the design of components or systems they will supply. While prior research shows the benefit of using this approach, execution remains a problem. The processes for identifying and integrating suppliers into the new product development (NPD) process in North American organizations are not understood well. This problem is compounded by the fact that design team members often are reluctant to listen to the technology and cost ideas made by suppliers in new product development efforts. We suggest a model of the key activities required for successful supplier integration into NPD projects, based on case studies with 17 Japanese and American manufacturing organizations. The model is validated using data from a survey of purchasing executives in global corporations with at least one successful and one unsuccessful supplier integration experience. The results suggest that (1) increased knowledge of a supplier is more likely to result in greater information sharing and involvement of the supplier in the product development process; (2) sharing of technology information results in higher levels of supplier involvement and improved outcomes; (3) supplier involvement on teams generally results in a higher achievement of NPD team goals; (4) in cases when technology uncertainty is present, suppliers and buyers are more likely to share information on NPD teams; and (5) the problems associated with technology uncertainty can be mitigated by greater use of technology sharing and direct supplier participation on new product development teams. A supplier's participation as a true member of a new product development team seems to result in the highest level of benefits, especially in cases when a technology is in its formative stages.     

Coordinating supplier involvement in product development projects: a differentiated coordination typology

Supplier involvement in product development has been a widely discussed theme in recent years. Sometimes, one 'best method' for involvement, derived from studies of one particular industrial context, has been suggested. In this article, however, various forms for coordinating such involvement are distinguished, based on a study of six different product development projects. Three main approaches are formulated and discussed: project integration coordination, disconnected sub-project coordination, and ad hoc coordination. Based on the empirical study and the literature, the drivers of different types of supplier coordination are discussed. Several managerial implications are suggested related to the need to differentiate inter-organizational coordination, not only from project to project but also throughout a project. The importance of taking into account short-term, project-based drivers as well as long-term strategic objectives of supplier coordination is also discussed.     

Customer involvement in new product development in B2B: The role of sales

Developing new products, and customer involvement in the process, have been frequent topics in the management literature. Focusing on the benefits and risks of customer involvement, prior research mostly black-boxed the process through which customers are involved. Little has been reported on the activities and timing related to customer involvement in new product development (NPD), and the literature provides limited guidance for how to orchestrate customers' involvement. Building on a longitudinal case study of the development of a new product over five years, we offer a comprehensive model of customer involvement in the NPD process, and elaborate on the role of sales in customer involvement. The contribution of this paper is threefold: first, we develop the concept of customer involvement as a pattern of interactions at the interface of the customer and supplier organizations. Second, we posit that NPD in a B2B context is an iterative process consisting of various parallel sub-processes. Third, we demonstrate that in a B2B context, sales function plays a central part in interfacing the supplier and customer organizations. Based on our findings we identify organizational capabilities critical for developing an effective customer-supplier interface.     

The role of open book accounting in a supplier network: Creating and managing interdependencies across company boundaries

Open book accounting (OBA) is an accounting method that has been put forward as a tool for managing interdependencies across company boundaries. This paper investigates the role of OBA in creating and managing interdependences in supplier relationships. In particular, consideration is given to how OBA deals with the embedded relationships in which interdependencies are both potentially aligning and conflicting with interdependencies in other relationships. An in-depth case study on the role of OBA within the retail industry in Sweden has been conducted. The study shows that the company used the OBA to create and manage interdependencies in different inter-organizational situations. The company used it in managing the interdependencies with the first tier supplier and down in the supply chain influencing second and third tier suppliers. However, OBA plays a key role in creating and managing the embedded supplier relationships. OBA was used to influence indirect relationships and their technical and organizational interfaces. It was also decisive in new resource combination and in the identification of new interfaces. Furthermore, OBA was used when actors defined the network boundaries and find new temporary solutions.     

The effects of buyer-supplier's collaboration on knowledge and product innovation

Drawing on marketing and management literature, this study investigates integration mechanisms between channel members. Specifically, the research framework is built upon the buyer-supplier gray-box integration approach, knowledge-based view, and agency theory. This study identifies and compares the effects of two gray-box integration mechanisms, namely supplier task involvement and joint planning, on two kinds of knowledge acquisition. I find that both supplier task involvement and joint planning positively influence manufacturers' product knowledge acquisition and end customer knowledge acquisition. Supplier task involvement has a stronger effect on knowledge acquisition than joint planning. The relationships between integration mechanisms and knowledge acquisition are contingent upon supplier incentives. Furthermore, this study also extends the literature by comparing the effects of two different kinds of knowledge on product innovation performance. Even though both product and end customer knowledge lead to better product innovation performance, end customer knowledge has a stronger effect than product knowledge on product innovation performance. Theoretical and managerial implications are discussed at the end.     

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.     

In Chains? An Empirical Study of Antecedents of Supplier Product Development Activity in the Automotive Industry*

In the literature on interorganizational collaboration in product development, considerable attention is given to supplier role classifications. Such classifications often link to a supplier's position in the overall supply chain, but the claim that this position has a substantial impact on its product development activities has seldom been empirically validated. The results from the present survey among Swedish automotive suppliers demonstrate that supplier product development activity is significantly affected by the position of the supplier in the supply chain and the supplier's strategic focus on innovation. While the latter has a stronger impact on product development activities, there is also an interaction effect implying that the effects of a supplier's innovation strategy are contingent on its supply chain position. Contrary to expectations, customer development commitment does not have any significant direct effect on supplier product development activities. Instead, this relation is fully mediated by supplier innovation strategy. These findings imply that, in contrast to conventional wisdom, product development activities are not strictly organized in “chains.” Although supply chains can be useful metaphors for understanding the distribution of regular production activities between firms, they arguably apply less to the distribution of product development activities.     

Effects of Supplier and Customer Integration on Product Innovation and Performance: Empirical Evidence in Hong Kong Manufacturers

While the beneficial impacts of supplier and customer integration are generally acknowledged, very few empirical research studies have examined how an organization can achieve better product performance through product innovation enhanced by such integration. This paper thus examines the impact of key supplier and customer integration processes (i.e., information sharing and product codevelopment with supplier and customer, respectively) on product innovation as well as their impact on product performance. It contributes to existing literature by asking how such integration activities affect product innovation and performance in both direct and indirect ways. After surveying 251 manufacturers in Hong Kong, this study tested the relationships among information sharing, product codevelopment, product innovativeness, and performance with three control variables (i.e., company size, type of industry, and market certainty). Structural equation modeling with correlation and t‐tests was used to test the hypothesized research model. The findings indicate a direct, positive relationship between supplier and customer integration and product performance. In particular, this study verifies that sharing information with suppliers and product codevelopment with customers directly improves product performance. In addition, this study empirically examines the indirect effects of supplier and customer integration processes on product performance, mediated by innovation. This has seldom been attempted in previous research. The empirical findings show that product codevelopment with suppliers improves performance, mediated by innovation. However, the sampled firms cannot improve their product innovation by sharing information with their current customers and suppliers as well as codeveloping new products with the customers. If the adoption of supplier and customer integration is not cost free, the findings of this study may suggest firms work on particular supplier and customer integration processes (i.e., product codevelopment with suppliers) to improve their product innovation. The study also suggests that companies codevelop new products only with new customers and lead users instead of current ones for product innovation. For managers, this study has demonstrated that both information sharing and product codevelopment affect performance directly and indirectly. Managers should put more emphasis on these key processes, especially when linked with product innovation. Managers should consider involving their suppliers and customers in the early stages of design. Information sharing with suppliers is also important in product development. As suggested by this study, extensive effort on supplier and customer integration should be made to directly augment current product performance and product innovation at the same time.     

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.     

The Role of Suppliers in Market Intelligence Gathering for Radical and Incremental Innovation*

Drawing on transaction cost economics theory, this study addresses the following research questions: (1) Does supplier involvement in market intelligence gathering activities have a greater impact on innovation success in predesign or commercialization activities? and (2) Does supplier involvement in market intelligence gathering activities have a greater impact on success in radical or incremental product innovation? Hypotheses are tested using both subjective and objective measures of success from a study of 205 incremental and 110 radical new product development projects. Results from the estimation of a two‐group path model suggest that this theoretical framework is useful in providing guidance as to when product developers should emphasize the gathering of market intelligence through suppliers. Consistent with conventional wisdom, the findings suggest that supplier involvement in market intelligence gathering activities are positively related to success in incremental innovations across predesign and commercialization activities. However, supplier involvement in market intelligence gathering activities is found to have no significant impact on market share and is negatively associated with perceived product performance in radical innovations in predesign tasks. Also, while there was no significant difference in market share for supplier involvement in market intelligence gathering activities between radical and incremental innovation in commercialization activities, supplier involvement in these activities did have a greater impact on perceived product performance in radical innovation than it did in incremental innovation. Although current practice suggests that teams allocate fewer resources to the gathering of market intelligence through their suppliers during predesign activities in incremental innovation projects compared with radical innovation projects, the findings in this study suggest that they should do the opposite. Shifting resources allocated for engaging suppliers in market information gathering activities in predesign activities from radical innovation projects to incremental innovation projects could increase the return on these investments. Alternatively, these resources currently allocated to the gathering of market intelligence through suppliers in predesign activities of radical innovation projects could also provide greater benefits if allocated to commercialization activities of radical innovation projects, where they have the greatest positive impact.     

Risky Business or Competitive Power? Supplier Involvement in Japanese Product Design

Notwithstanding the alleged risks of outsourcing design work, leading manufacturers in the Japanese automotive industry collaborate closely with their key suppliers. Despite widespread recognition of the effectiveness of these close-knit supplier networks, however, little research exists on the factors that affect the purchase of design work from suppliers. S. Nazli Wasti and Jeffrey K. Liker fill this gap by exploring the factors that affect Japanese automotive firms' purchase of design work from their component suppliers. Using data from a survey of 122 Japanese automotive component suppliers, their study addresses two key questions. First, what factors lead Japanese buyers to involve some suppliers heavily in design while giving others relatively little control over design decisions? And second, does the Japanese practice of involving suppliers in design offer performance benefits? The study focuses on first-tier suppliers of parts, assemblies, and complete subsystems (e.g., audio, fuel and emissions, heating and air conditioning). The study does not include suppliers of raw materials and chemicals, assembly and processing equipment, indirect materials, tooling and dies, computers and software, or engineering and business consulting services. The study breaks down the broad concept of supplier involvement in design work into three measurable elements: the extent to which the supplier influences decision-making during the early stages of product development; the amount of control the buyer retains over the design; and the frequency of design-related communication between the buyer and the supplier. Factors that have a positive effect on the level of supplier involvement among the companies studied include technological uncertainty of the component and the supplier's in-house technical capabilities. For companies in the study, the level of competition in the supplier market has a negative effect on the degree of supplier involvement in design. The responses indicate that supplier involvement offers performance benefits for both the supplier and the buyer. For the supplier firms studied, increased involvement in the design process permits greater focus on design for manufacturability (DFM). And of course, supplier-generated design improvements clearly benefit the buyers, allowing these firms to capitalize on the experience and the insight that their suppliers have regarding the parts that they supply.     

The Ability to Minimize the Timing of New Product Development and Introduction: An Examination of Antecedent Factors in the North American Automobile Supplier Industry

The importance of overall timing in the new product development and the new product commercialization processes has been widely recognized in the literature. We examined 14 firm-level practices, later reduced to four factors, that influence the ability to minimize new product development and introduction times overall relative to competitors. The factors are (1) human resource management, (2) synergistic integration, (3) supplier closeness, and (4) the design-manufacturing interface. An empirical study of the North American automobile supplier industry found some support for the four-factor model of antecedents to timing ability: synergistic integration and supplier closeness were both significantly related to development and introduction time minimization ability. The implications of these findings for product development managers and academic researchers are discussed.     

Why did we make that cheese? An empirically based framework for understanding what drives innovation activity

In the more recent product development literature the interplay between R&D skills and competencies and market skills and competencies is seen as a major determinant of successful innovation. The study reported in this article was done in order to cast more light on these two constructs in an industry with low R&D expenditures, but where product development is nevertheless considered to be strategically important. That industry is the food processing industry. The results of a series of case studies indicate that constructs other than R&D and market orientation may be more appropriate for understanding innovation and explaining innovation success in the case material. A new set of constructs focusing on what causes specific innovation activities to occur is proposed and a revised framework is developed.     

How integrating industrial design in the product development process impacts on company performance

There is a growing belief that investing in industrial design is beneficial to company performance. This article sheds more light on how and when integrating industrial design in the product development process can enhance a company's competitive position. The basic premise is that the impact of industrial design on company performance is not unconditional, but dependent on industry evolution and design strategy. We opted to define industrial design in a general way, namely as the activity that transforms a set of product requirements into a configuration of materials, elements and components. This activity can have an impact on a product's appearance, user friendliness, ease of manufacture, efficient use of materials, functional performance, and so on. The empirical data incorporated in this study stems from two Dutch manufacturing industries, namely home furniture and precision instruments. Home furniture and precision instruments were selected because the strategy of integrating industrial design in the product development process is rather mature in the first‐named industry and emerging in the second. We collected data from firms investing considerably in industrial design (n = 23) and firms investing little to nothing in industrial design (n = 24), using a semistructured questionnaire that was administrated during face‐to‐face sessions with senior managers. Two out of the three research hypotheses were supported. It was found that the extent to which firms integrate industrial design in new product development projects has a significant and positive influence on company performance (Hla), in particular when the strategy of investing in industrial design is relatively new for the industry involved (Hlb). There was no systematic pattern indicating that design innovation is more important in industries where the use of design is mature than in industries where the use of design is emerging (H2). Instead, we found that design innovation has significant positive performance effects in both types of industries. One important managerial inference from our study is that new product development managers should consider the changing nature of competition during industry evolution while developing strategies that encompass the use of industrial design in new product development. Another important managerial inference is that, besides being innovative in the field of products, being innovative with respect to design and design strategy can help to enhance competitiveness regardless of industry evolution.     

Differential Effects of the Primary Forms of Cross Functional Integration on Product Development Cycle Time

In markets characterized by high rates of technological and market change product life cycles tend to be shorter, resulting in the increased importance of competing on the basis of product development cycle time. For firms operating in these dynamic market environments, competing on the basis of cycle time may not only be a source of competitive advantage, but in some industries may actually be essential for survival.
In this investigation the relative importance of five forms of cross functional integration and R&D integration of information or knowledge from past projects were explored in terms of their effects on product development cycle time. The five forms of cross functional integration included R&D/marketing integration, R&D/customer integration, R&D/manufacturing integration, R&D/supplier integration, and strategic partnerships. A sample of 65 U.S. and Scandinavian high technology firms (or strategic business units) were studied. The sample included firms from the computer, telecommunications, instruments, specialty chemicals, biotechnology, and software industries.
The results demonstrated that R&D integration of knowledge from past projects explained the largest degree of variation in product development cycle time. R&D/marketing integration and R&D/customer integration explained the next largest degree of variation in cycle time reduction. Cross cultural generalizability tests demonstrated that the results were generalizable across the U.S. and Scandinavian samples of firms. In addition, the results were found to be generalizable across industry or product category for five of the six forms of integration.     

Bridging inter- and intra-firm boundaries: management of supplier involvement in automobile product development

Outsourcing has become an important strategy for many firms. Yet, firms need to compete with their competitors who also outsource and may share the same suppliers. This article explores how a firm could outperform others in managing the division of labor with a supplier in product development. Drawing on the empirical data collected from the Japanese auto industry, this paper shows that an automaker needs capabilities to coordinate various activities both externally with a supplier and internally within its own organization, in order to gain better component development performance. Overall, the results imply that outsourcing does not work effectively without extensive internal effort. Copyright © 2001 John Wiley & Sons, Ltd.     

The Effects of Supplier Involvement and Knowledge Protection on Product Innovation in Customer–Supplier Relationships: A Study of Global Automotive Suppliers in China

Globalization drives firms to develop product innovation through their global supply chains. While innovations generated by supply channel members, as opposed to individual partners, are playing an increasingly important role in the success of all supply chain partners, there has been limited research on how supply chain relationships cultivate the process of such innovation generation, particularly in emerging markets. Correspondingly, this study explores how multinational suppliers can develop adaptive product innovation to create competitive advantage in emerging markets. Drawing on the knowledge‐based view and transaction cost economics, this study investigates the influence of supplier involvement and other factors on supplier innovation and performance. The results of a survey of 170 multinational automobile suppliers in China provide support for most of the hypotheses. Specifically, supplier involvement in codesign has an inverted U‐shaped relationship with product innovation. Furthermore, knowledge protection, trust, and technological uncertainty are all found to drive greater product innovation. In addition, the institutional environment moderates the effect of product innovation on performance. Overall, this study enhances our understanding of how MNEs can acquire local knowledge and develop adaptive products in emerging markets.
