The Roles of Marketing and Industrial Design in Discontinuous New Product Development*

Radical or “discontinuous” products based on new technological breakthroughs are playing an ever‐increasing role in the success of firms. However, little research has been conducted that investigates the roles of marketing and industrial design (ID) in the development of these types of products. Further, past research has tended to overlook the role that industrial design, and the impact of the marketing‐industrial design interaction, can have on the development of discontinuous new products. Frequently, the term design is used broadly or is equated with engineering; thus, while the marketing–research and development (R&D) interaction is studied, the marketing–ID as well as the industrial design–R&D relationships are not considered. This article examines the roles of marketing and industrial design in the product development process for discontinuous innovations. Specifically, questions concerning how and the degree to which marketing and industrial design are integrated into the development process are investigated. The investigation employs multiple methods, or triangulation, in order to secure an in‐depth understanding of the roles of these disciplines. In the course of examining these questions, key factors influencing industrial design and marketing involvement are identified and preliminary models are examined. The research, which was conducted in two phases, employed a mixed‐method, multiple sample design. The methods used included a survey, field observation study, and depth‐interviewing. Data were collected from three different samples: R&D managers, project team members (including personnel from various disciplines—marketing, R&D, industrial design, engineering, etc.), and industrial design managers. The use of the different data sources and sampling of various groups of managers was employed in order to provide a rich context for investigating the research questions of interest. In addition, a preliminary analysis of factors (e.g., degree of product discontinuity, product innovation objectives, process discontinuity, process formality) identified in the first phase was conducted, and these relationships were explored further in the second phase of the research. Findings across the two phases of this research suggest that the development of discontinuous new products involves a process that is different from more conventional new product development—particularly as it concerns the roles of marketing and industrial design. The high degree of discontinuity inherent in such projects, along with the strong R&D orientation often surrounding them, results in delayed involvement of marketing and ID, as well as altering their roles in the new product development (NPD) process. Factors such as the degree of product discontinuity (DPD), process discontinuity (PCD), and process formality (PF) seemed to exert a differential influence on the involvement of marketing and ID. Although their roles and involvement are altered in discontinuous new product development, this research suggests that marketing and ID roles in this context involve increased challenges with respect to validation of key assumptions and product application directions. Additionally, managers operating in this development context need to explicitly consider the influence of factors such as discontinuity level in undertaking NPD projects with respect to how it affects the execution of industrial design and marketing activities.     

The Role of Departmental Thought Worlds in Shaping Escalation of Commitment in New Product Development Projects

The debate over whether and how thought worlds of different departments (especially marketing and research and development [R&D]) affect managers' decision-making behavior in new product development (NPD) is ongoing. A key challenge of these decisions is to deal with deteriorating NPD projects, which are often subject to escalation of commitment (EoC), with many firms wasting billions of dollars by throwing good money after bad NPD projects. However, understanding departmental thought worlds and their role for EoC in NPD could help firms stop this profusion. Thus, this research provides answers to the question of how thought worlds affect managers' tendency toward EoC in NPD decision-making—both in general and under certain project characteristics. To do so, we conducted four studies based on real-life scenarios with 460 highly experienced NPD managers from marketing and R&D, thus ensuring high validity and reliability. Our research is the first to explore the impact of thought worlds on EoC, thereby detecting that the importance of managers' thought worlds for shaping EoC varies with the NPD project's characteristics. Thus, depending on the specific project situation, different types of managers may be more or less capable of making proper NPD decisions. Moreover, results show that belief updating serves as a respective key mediator. Doing so enriches the theory by showing that managers' thought worlds can substantially influence a major mechanism (i.e., belief updating) of coping with cognitive dissonance. Finally, post hoc tests reveal departmental differences in EoC behavior between marketing and R&D that vary with a project's characteristics. These results imply that firms need to carefully consider who is in charge of making decisions on NPD project continuance in different project situations.     

International R&D partnerships and intrafirm R&D–marketing–production integration of manufacturing firms in emerging economies

Although cross-functional integration is important for research and development (R&D), research about implications of cross-functional integration has been rather sparse. In new product development (NPD), no study to date has examined intrafirm as well as interfirm integration of key functions such as intrafirm R&D–marketing–production together with interfirm integration of host R&D–partner R&D. Such marketing and operations interface contributes to a better understanding of how operational and marketing activities impact on competitiveness and firm performance. This study collected data from 202 electronics manufacturing firms operating in an emerging economy, mainland China and Hong Kong with international R&D partnerships. The findings indicate that a high level of R&D integration between firms improved NPD performance when cross-functional integration is based on existing rather than new product configurations and key technologies. Interestingly, in high distance situations, cross-functional integration in the production validation stage generated NPD success. The findings show that high environmental uncertainties lead to a high level of host and partner firms R&D integration. However, product newness has no significant effects on R&D integration in any of the NPD stages.     

Governance of supplier collaboration in technologically uncertain NPD projects

Firms that are searching for new technologies from suppliers through collaborative new product development (NPD) need to devise effective approaches for governing the supplier relationship. Based on in-depth case studies of four collaborative NPD projects, this paper shows that in projects with a high degree of uncertainty (1) firms achieve governance by simultaneously limiting supplier involvement and allowing for high levels of collaboration, (2) transactional and relational governance have distinct roles in achieving limited supplier involvement and establishing high levels of collaboration, and (3) transactional and relational governance are organizationally separated. These findings have implications for the complementary use of relational and transactional governance, as well as for the role of purchasing and R&D in technologically uncertain NPD projects.     

Exploring the differences in performance measurement between research and development: evidence from a multiple case study

Researchers and practitioners have recently paid great attention to research and development (R&D) performance measurement, although it is acknowledged to be a very challenging task because of R&D intrinsic uncertainty and complexity levels. In this paper, the problem of designing a performance measurement system (PMS) for R&D activities is addressed; specifically, we investigate if and how the design of the PMS is influenced by the type of activity it is applied to, namely Basic and Applied Research or new product development (NPD). We first develop a theoretical framework that comprises the main constitutive elements of a PMS for R&D. Then the framework is used for supporting a multiple case study analysis involving eight Italian technology-intensive firms. The research results show that the criteria for designing the constitutive elements of the PMS are radically different in Basic and Applied Research and NPD. The reasons behind the observed dissimilarities in the design criteria are widely discussed in the paper, as well as their implications for R&D managers.     

The R&D and marketing cooperation across new product development stages: An empirical study of Taiwan's IT industry

This study extends the new product development (NPD) process research to a new environmental context (Taiwan's IT industry) and a new business type (original design manufacturing, ODM). Taiwan's IT industry has achieved a very outstanding performance during the last two decades. The island's experience is quite valuable for those emerging countries that are struggling to transform themselves from producing low-value goods to making high-technology products. After analyzing the data collected from 153 research and development (R&D) and marketing managers in Taiwanese IT firms, this study finds that the higher the perceived importance of R&D-marketing cooperation is, the higher the attained level of R&D-marketing cooperation will be. Consequently, a better NPD performance can be achieved. This study additionally reports that a firm that has adopted a Defender innovation strategy attains a lower level of R&D-marketing cooperation, and has a poorer NPD performance than those firms that adopted either Prospector or Analyzer innovation strategies. Finally, environmental uncertainty has no significant impacts on the perceived importance and the attained level of R&D-marketing cooperation.     

Making Trade-Offs in the New Product Development Process: A German/US Comparison

Using a conjoint analysis experiment, Ashok Gupta, Klaus Brockhoff and Ursula Weisenfeld present how R&D, marketing, and manufacturing managers in Germany make trade-offs among three critical variables in the new product (NPD) process: development schedule, development costs, and product performance. The findings are compared with a similar study of US firms. This comparison underscores the basic problem: US managers do not emphasize product development speed to the same extent as do German managers.     

Navigating the purchasing power gap in new product development in multinational corporations

Multinational corporations (MNCs) face a significant purchasing power gap of customers between developed and emerging economies. In R&D intensive industries making physical products, MNCs can benefit from economies of scale. Therefore, managers strive to achieve a product standardization–adaptation (S‐A) balance when navigating the purchasing power gap. Through focusing on five MNCs headquartered in developed countries, I examined how MNCs can achieve such a balance through new product development (NPD). I found that (1) an S‐A balance can be achieved through three NPD strategies (product simplification, product retaining, and reverse innovation); (2) managers need to take into account five key factors when choosing NPD strategies (product complexity, product modularity, brand strategy, position in local competition, and internal technical standards); and (3) the NPD strategies can be implemented through structural separation, temporal separation, and a shared value. This research reveals the complexity of achieving an S‐A balance when managers navigate the purchasing power gap in NPD. Different NPD strategies have certain advantages and shortcomings. High product complexity and product modularity can serve as favorable conditions for a product simplification strategy. A brand strategy of leading‐edge technologies can serve as an adverse condition for a product retaining strategy. Strong local competitors in emerging markets can be a motivation for a reverse innovation strategy, while stringent internal standards for safety can be an adverse condition. This research also reveals the nuances of implementation of NPD strategies in terms of managing innovation and refinement activities. MNCs may need temporal separation when adopting both downhill and uphill NPD strategies.     

The Impact of Cross-Functional Joint Involvement Across Product Development Stages: An Exploratory Study

Cross-functional integration offers numerous, well-documented benefits for new-product development (NPD), but it also can carry significant costs. Joint involvement of R&D, manufacturing, and marketing personnel can increase the quality, the manufacturability, and the marketability of the final product. However, building consensus among these groups, with their differing perspectives and goals, may require time-consuming meetings as well as tremendous finesse from the managers who guide the NPD effort. Those managers require an approach to cross-functional integration that strikes a balance between efficiency and effectiveness. X. Michael Song, R. Jeffrey Thieme, and Jinhong Xie propose that the right mix of cross-functional involvement may differ depending on the stage in the NPD process. They also suggest that blindly promoting the involvement of all functional areas in all stages of the NPD process may actually decrease NPD performance. They test these propositions in a study that examines the relationships between new product performance and cross-functional joint involvement between R&D, manufacturing, and marketing in five major stages of the NPD process: market opportunity analysis, planning, development, pretesting, and launch. Their objective in this study is to identify patterns of effective cross-functional involvement in different NPD stages. The study uses data collected from 236 managers working in the R&D, manufacturing, and marketing departments of 16 Fortune 500 firms. Their findings suggest that new-product success may be more likely when a firm employs function-specific and stage-specific patterns of cross-functional integration than it is when the firm attempts to integrate all functions during all NPD stages. For example, during the market opportunity analysis stage, the findings suggest that joint involvement between R&D and marketing may be productive, but joint involvement between R&D and manufacturing and among all three functions may be counterproductive. The results also indicate that joint involvement among all three functions either does not have a significant effect on new product success or may be counterproductive in all stages of the NPD process. For the firms in this study, the three functions seem to take turns playing the central role in cross-functional activities. During the product planning, development, and testing phases, the role of the focal function, or communication hub, shifts from manufacturing to R&D and then to marketing.

The Effects of Knowledge Depth and Scope on the Relationship between R&D Alliances and New Product Development

In this study, we extend the new product development (NPD) literature that proposes that firms' knowledge depth, defined as the reuse of well understood technical knowledge, and scope, defined as the use of newly acquired technical knowledge, and new knowledge accessed from R&D alliances all positively impact NPD. Building on the knowledge‐based view of the firm, we posit that the impact of firms' R&D alliances is limited when their internal knowledge depth and scope are adequate for NPD needs. We suggest that although firms form R&D alliances to gain the right to access external knowledge of R&D alliance partners, they are not obligated to invest in resources to integrate external knowledge from R&D alliances. We propose that they wait to see if their internal knowledge depth and scope prove sufficient for NPD. If the external knowledge proves to be unnecessary, firms choose not to invest the resources required to integrate this knowledge with their internal knowledge. Alternatively, we suggest an increased impact of R&D alliances on NPD when firms are more limited in their internal knowledge depth and scope. We propose that when knowledge depth and scope prove insufficient, firms make the additional investments required to integrate external knowledge from R&D alliances with their internal knowledge stock. This reasoning is consistent with real options theory as it has been applied in alliance research, where strategic alliances are characterized as real options. We find support for our hypotheses using panel data of 738 firm year observations for 143 U.S. biopharmaceutical firms operating in 2007. Our study contributes to the NPD literature and suggests new directions for future research.     

Managing strategic intellectual property assets in the fuzzy front end of new product development process

The strategic use of intellectual property (IP) is crucial for technology-based companies to gain competitive advantage. The recent transformation of the US patent system brings new challenges and opportunities in this arena. In this regard, this study attempts to identify techniques which can help with IP evaluation and selection in the fuzzy front end (FFE) of new product development (NPD) process. This study combines data collection methods such as mining the literature, conducting in-depth interviews, surveying questionnaires, and analyzing cases. This research serves as an analysis of modern literature and identifies a multicriteria weighted scoring model that can be employed to help with the patent decision process. The criterion to discern patent eligibility is a contended discussion. For this survey administration, 300 companies, as the targeted sample, were randomly selected to be reached from LexisNexis database. Consequently, this paper identifies the key decision criteria to incorporate into this model and obtains weights gathered from surveying IP professionals and R&D managers in US-based electronics manufacturing firms (SIC code: 36). This study proposes a structured approach to identify ideas that should be patented in the FFE of NPD process by way of an analysis of pertaining literature and case studies. The technique we present in this paper could be essential for many firms to achieve IP success as their strategic means. Moreover, this tool can help R&D managers not only speed up the FFE of NPD process but also make more informed and target-worthy decisions for IP filing.     

The Impact of Organizational Integration and Product Development Proficiency on Market Success

This research investigates three major hypotheses important to new product market success: the greater organizational integration during the development of new products, the greater the market success; the greater organizational integration during the development of new products, the greater new product development proficiency; and the greater new product development proficiency, the greater the market success. “Organizational integration” is defined as the degree of cooperation and communication between internal and external NPD “support” groups and NPD teams. “NPD process proficiency” is defined as how well new product development stages and the new product development process as a whole is performed. “New product market success” is represented by four measures: the degree to which profits and sales exceeded or fell short of what was expected, and the degree to which the new product was perceived to exceed or fall short of expectations related to entering existing and new markets. Information was obtained concerning the most and least successful new products of U.S. firms in the medical instruments, the electrical equipment, and the heavy construction equipment industries. The field survey approach was utilized in which surveys were mailed to recipients such as new product development managers who already had been designated by executives of the sample firms. Several important findings were uncovered during this research. Overall organizational integration was found to be significantly associated with new product market success. Internal integration, the coordination between new product development teams and functional departments, was found to be significantly related to product market success. A significant relationship between new product development proficiency during the NPD “post-launch stage” and the degree of integration between an NPD team and external NPD organizations, such as customers and suppliers, was detected. During the post-launch stage, new product development proficiency also was found to be significantly related to new product market success. These findings suggest several important implications for new product development managers and scholars.     

The Roles of Sustainability Orientation and Market Knowledge Competence in New Product Development Success

Firms’ sustainability orientation (SO) is widely understood as a strategic resource, which can lead to competitive advantage and superior (financial) performance. While recent empirical evidence suggests a moderate and positive relationship between SO and financial performance on a corporate level, little is understood about the influence of SO on new product development (NPD) success. Building on the natural‐resource‐based view (NRBV) of the firm, we hypothesize that firms’ SO positively influences NPD success, because of efficiency gains and differentiation advantages. However, scholars have also argued that the win–win paradigm postulated by NRBV might not always hold because NPD managers might find it difficult to balance sustainability objectives with the needs of their customer and the competitive dynamics in their markets. It is, therefore, proposed that market knowledge competence (MKC) is an important capability, which helps firms to balance social and ecological objectives with economic goals such as profitability and market share. Using data from 343 international firms from 24 countries that was collected by the Product Development and Management Association, structural equation modeling results suggest that (1) SO positively influences NPD and that (2) this relationship is partially mediated by firms’ market knowledge capabilities. The findings suggest that strategic‐level SO and MKC are complementary in that they help in balancing trade‐offs between sustainaility objectives and profitability goals. In this way, the study contributes to a better understanding of how critical NPD practices can help managers to translate firms’ SO into NPD success. The article concludes by highlighting implications for product innovation managers.     

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.     

Evolving schemes of interpretation: investigating the dual role of architectures in new product development

Should product architectures be considered inputs to – or outputs from – new product development (NPD)? Whereas the mirroring hypothesis suggests the former, NPD stage models suggests the latter. Elaborating on these conflicting propositions, this paper analyses the relationships between product architectures and development processes in NPD projects. The analysis demonstrates how project managers use product architectures to interpret their tasks and devise appropriate responses to perceived challenges. Thus, architectures provide useful linkages between knowledge development and organisational change in R&D organisations.     

PERSPECTIVE: Trends and Drivers of Success in NPD Practices: Results of the 2003 PDMA Best Practices Study*

Since 1990, the Product Development & Management Association (PDMA) has sponsored best practice research projects to identify trends in new product development (NPD) management practices and to discern which practices are associated with higher degrees of success. The objective of this ongoing research is to assist managers in determining how to improve their own product development methods and practices. This paper presents results, recommendations, and implications for NPD practice stemming from PDMA's third best practices study, which was conducted in 2003. In the eight years since the previous best practices study was conducted, firms have become slightly more conservative in the portfolio of projects, with lower percentages of the total number of projects in the new‐to‐the‐world and new‐to‐the‐firm categories. Although success rates and development efficiencies have remained stable, this more conservative approach to NPD seems to have negatively impacted the sales and profits impact of the new products that have been commercialized. As formal processes for NPD are now the norm, attention is moving to managing the multiple projects across the portfolio in a more orchestrated manner. Finally, firms are implementing a wide variety of software support tools for various aspects of NPD. NPD areas still seriously in need of improved management include idea management, project leadership and training, cross‐functional training and team communication support, and innovation support and leadership by management. In terms of aspects of NPD management that differentiate the “best from the rest,” the findings indicate that the best firms emphasize and integrate their innovation strategy across all the levels of the firm, better support their people and team communications, conduct extensive experimentation, and use numerous kinds of new methods and techniques to support NPD. All companies appear to continue to struggle with the recording of ideas and making them readily available to others in the organization, even the best. What remains unclear is whether there is a preferable approach for organizing the NPD endeavor, as no one organizational approach distinguished top NPD performers.     

The Effects of Environmental Turbulence on New Product Development Strategy Planning

Managers need guidance on how to cope with turbulent environments in order to improve corporate performance. Research on environmental turbulence has suggested that firms adopt a less centralized, more organic structure in dynamic, uncertain environments. Little work has been done specifically, however, on how environmental turbulence affects strategy planning for new product development (NPD). In this article, we specify a baseline model with firm innovativeness, market orientation and top management risk taking as antecedents to NPD speed and corporate strategic planning; these in turn are modeled as antecedents to NPD program (not project) performance. Two conceptualizations of the role of environmental turbulence are examined: (1) that market turbulence and technological turbulence are additional direct antecedents to NPD program performance; and (2) that the baseline model is moderated by turbulence (that is, that the strengths of the paths differ depending on levels of turbulence). A cross-sectional survey methodology including four diverse industries [automotive, electronics, publishing, and manufacturing/research and development (R&D) laboratories] was used to test the hypotheses. The latter conceptualization is supported. In particular, the paths from innovativeness to strategic planning and from risk taking to NPD speed are significantly greater in highly turbulent environments. A set of managerial recommendations and implications are provided. First, managers must recognize the possible improvements in new product performance by actively including NPD personnel in corporate strategic planning and also by involving corporate planners in NPD activities. Second, managers also should recognize that turbulent environments heighten the need to make risky investments, and sometimes, risky decisions; risk-taking decisions ought to be encouraged in such environments.     

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.     

Integrating the R&D and Patent Functions: Implications for New Product Performance

This paper examines the impact of cross‐functional integration between the research and development (R&D) and the patent functions on new product development (NPD) performance. The attitudinal (collaboration) and the behavioral (contributions of the patent function to NPD) dimension of cross‐functional integration between the R&D and the patent functions are distinguished. It is also investigated if the level of innovativeness moderates the relationship between the attitudinal and the behavioral dimension of cross‐functional integration between the R&D and the patent department and NPD performance. The four hypotheses are tested based on a multi‐informant sample of 101 NPD projects which are nested within 72 technology‐based firms or strategic business units from multiple industries in Germany. The results show that the attitudinal and the behavioral dimensions of cross‐functional integration between the R&D and the patent functions have a significant and positive impact on NPD performance. This lends empirical support for the notion expressed in the literature that certain managerial capabilities are important for understanding the effect of patenting on appropriability outcomes such as value creation and performance. The level of cross‐functional integration between the patent and the R&D functions appears to be one of these critical patent management capabilities that affect the returns from investments into patents. There is support for the hypothesis that the context matters for the effect of cross‐functional integration between the R&D and the patent functions on NPD performance. In line with the initial hypothesis, the level of innovativeness positively moderates the impact of the behavioral dimension of cross‐functional integration between the R&D and the patent department on NPD performance. In contrast to the initial hypothesis, the findings reveal no moderating effect of the level of innovativeness on the link between the attitudinal dimension of cross‐functional integration between the R&D and the patent department and NPD performance. This implies that joint objectives and an open and trustful working relationship between the R&D and the patent functions are not sufficient for achieving higher NPD performance if firms aim to develop very innovative products. In the case of highly innovative products, the actual behavior, that is, the specific contributions of the patent department to the NPD project, matters. Overall, these findings have important implications for improving performance by means of effectively integrating the patent and the R&D functions during NPD.     

Psychosocial antecedents of communication,trust, and relationship effectiveness in new product development projects: a functional manager perspective

The basic differences between marketing managers and their technically trained counterpart managers [e.g., research and development (R&D), engineering, and manufacturing managers] in terms of work experience, training, and differing decision‐making styles have often been suggested as a source of conflict, which acts as a barrier to effective working relationships and integration during new product development (NPD) work. In this paper, we empirically explore this issue by developing and testing a model of psychosocial differences (thought worlds and psychological distance) between the two groups of managers and their effect on communication, trust, and relationship effectiveness during NPD projects. We find that while thought world differences do still matter, it was from a marketing perspective that they had a stronger effect. These findings have implications for top management trying to manage the functional manager interface during NPD projects. We propose a semi‐formalized approach to relationship building that may speed up the acquisition of social data that is often necessary to elevate working relationships to trusting ones and improve the efficiency of NPD work. Our model is tested using data from two samples, 184 technically trained managers and 145 marketing managers from Australian companies involved in NPD work.
