Given industry competitiveness, how do firms' new product development (NPD) process designs differ when responding to an innovation mandate? How do NPD design elements differ across firms when implementing NPD processes? These design elements are strategic business unit (SBU) senior management involvement, business case content, customer interactions, and cross‐functional integration. What are the consequences of different combinations of NPD process design elements for innovation productivity? We explore these questions via a collective case study of newly implemented NPD process designs at three different SBUs of a major US‐based international conglomerate, 1 year after receiving the mandate to grow through innovation. Our analysis suggests that industry competitiveness and firm characteristics influence the NPD process design as SBUs employ distinct combinations of NPD design elements. The differential emphasis on design elements leads to variation in process design and divergence in innovation productivity. 相似文献

This article addresses the integration of sales channels after mergers and acquisitions (M&A) by appraising the strengths, weaknesses, and biases associated with the four most common frameworks for evaluating sales channels (sales management, historical performance, strategic fit, and customer choice) for their appropriateness in a post-M&A context. The authors develop a methodological approach that uses a balanced-scorecard framework to guide managers through the sales channel integration process, and then apply this approach to the merger of two industrial firms' sales organizations across 21 territories. In so doing, they reveal various pitfalls and propose and test some analytical corrections. Longitudinal performance data support comparisons across the different evaluative frameworks; in particular, the sales management and customer choice frameworks provide the most insight into channel partners' post-integration performance. The results support the premise that channel integration can be improved by accounting for factors unique to the M&A context and using an approach that triangulates multiple perspectives. 相似文献

There has been a shift from transactional to relational exchange and relationship marketing both in the business to business and professional services contexts. This paper seeks to explore the manner in which personal relationships affect the process and outcomes of purchasing of professional business services. Specifically, it focuses on the role of the professional service providers as boundary spanners in the formation of personal relationships. These personal relationships constitute the underlying basis of long-term relationships between the purchasing and provider organizations in such complex service settings. The findings of this study demonstrate that the manner in which the boundary spanners cultivate relationships support the concept of relationship specific tasks. It extends this conception by use of the data to outline the chronological process over time Understanding the roles, function, and ultimately importance, of these relationships facilitates the identification and development of appropriate strategies to manage these relationships. 相似文献

The wireless industry is one of the most capital intensive high-technology industries. This paper applies real options techniques to estimate investments under uncertainty in two new ventures: (a) deferral of the expansion from 2.5G to 3G networks; and (b) expansion of a 2.5G network using Wi-Fi as an alternative technology. The cases are examined and analyzed both qualitatively and quantitatively, using realistic assumptions and parameters. Investment cost, number of subscribers, pricing of services, and risk are at the core of investment decision processing. In both cases, sensitivity analysis of the value of the (real) option considering the above key parameters was conducted, to extrapolate useful findings that should be taken into consideration by the decision makers in wireless companies. 相似文献
