Notwithstanding the best efforts of outstanding managers, project team members, researchers, and consultants, no product development plan can guarantee success. Every new products organization will experience its fair share of failures, but a firm can take steps to ensure that its failures do not outweigh its successes. By benchmarking the competition, a firm can gain insight into best practices–the factors that lead most directly to new product success. To help identify these best practices, X. Michael Song, William E. Souder, and Barbara Dyer develop and test a causal model of the relationships among the key variables leading to new product performance. The proposed model identifies five factors that lead to marketing and technical proficiency: process skills, project management skills, alignment of skills with needs, team skills, and design sensitivity. According to the model, marketing and technical proficiency directly determine product quality, and ultimately lead to new product success or failure. The causal model was tested using information on 65 completed projects–34 successes and 31 failures–from 17 large, multi-divisional Japanese firms. The study participants develop, manufacture, and market high-technology consumer and industrial products. These firms judged the success or failure of the projects in this study by using seven criteria: return on investment, profit, market share, sales, opportunities for technical leadership, market dominance, and customer satisfaction. These firms generally assigned the greatest importance to customer satisfaction, opportunity creation, and long-term growth. For the most part, the responses from these firms support the relationships presented in the causal model. According to the respondents, marketing proficiency and product quality have a strong, positive influence on their new product performance, as do process skills, project management skills, and alignment of skills and needs. The responses highlight the importance to these firms of responsiveness to customer wants and needs, as well as ensuring a close fit between project needs and the firm's skills in marketing, R&D, engineering, and manufacturing. Somewhat surprisingly, the responses do not support the model's suggested relationships between skills/needs alignment and technical proficiency or between technical proficiency and product quality.  相似文献

In 1977 the Foreign Corrupt Practices Act (FCPA) was enacted to penalize US firms and their employees for paying bribes to foreign government officials. If bribe payments influence the awarding of contracts and the FCPA regulation differentially affects US exporters compared to foreign competitors, then US exporters' bribe-paying ability and market share would be expected to decline. This study provides empirical evidence that the FCPA had a negative effect on US exports to non-Latin American countries but not to bribery prone ones in Latin America.  相似文献

Exports may enhance learning through production-induced learning by doing, learning to export by doing, and flows of information from customers. We provide evidence on the learning effects of export destination for Costa Rica for 1955 through 1980. We examine Granger-causality results and export trends to determine relationships between exports to the Central American Common Market (CACM), the rest of the South, and the North. Increasing exports to the CACM appear to promote learning in machinery, leather, and intermediate manufactures. We also find that the CACM redirects some exports away from Northern markets, probably with damaging consequences.  相似文献

The exchange of technical personnel between organizational actors in a supply network has become known as Guest Engineering (GE). Despite increasing popularity as an inter‐organisational arrangement (especially in the automotive sector) it has generated relatively little academic research and therefore this paper seeks to extend our understanding of GE by exploring how its scope is determined, what motivates the participants and how the relationships evolve. The paper draws on extant GE, supply networks and Resource‐Based View (RBV) literature to derive research propositions that are used to analyse empirical work carried out with four automotive suppliers and four automotive OEMs. A number of preliminary conclusions are drawn. At a micro‐project level, the criticality of the individual 'playing the GE role' is highlighted, as are related concerns that collaborative team structures often fail to address broader social/cultural characteristics. At a macro‐project level, the study argues that difficulties and mistrust will often characterise integrated and competitively successful GE relationships. Finally, at a strategic level, GE needs to be understood as a process of resource transfer and transformation, and therefore the management of interdependency and power asymmetry are core considerations in effective adoption. The paper concludes with recommendations for further critical and practical work.  相似文献

A model of regional market development is constructed which captures the inefficiencies typical in most of the related literature, and a variety of corrective policy options are explored. For taxes and subsidies, there is no dominant policy with each limited by the zero-profit constraint on entry, informational problems, or adverse distributional considerations. Discriminatory pricing decreases efficiency, but uniform pricing achieves optimal allocations. Public production has certain informational advantages.  相似文献

The fact that there are times when market movement is random and times when it is not is interpreted in terms of the hypothesis that the price of a stock is an aggregate opinion — the resultant of the opinions and decisions of a community of investors. Price, like any other opinion, will be most vulnerable to social and other sources of influence during times of uncertainty, an aggregate psychological state which can generate the kind of statistical dependence characteristic of non-random walks. Ramifications of this hypothesis are explored in a variety of stock market behaviors, such as the effect of tips, the impact of runs on trading volume during rising and falling markets, and the like.  相似文献
