This article presents the results of a study on the evaluation criteria that companies use at several gates in the NPD process. The findings from 166 managers suggest that companies use different criteria at different NPD evaluation gates. While such criteria as technical feasibility, intuition and market potential are stressed in the early‐screening gates of the NPD process, a focus on product performance, quality, and staying within the development budget are considered of paramount importance after the product has been developed. During and after commercialization, customer acceptance and satisfaction and unit sales are primary considerations. In addition, based on the performance dimensions developed by Griffin and Page (1993), we derive patterns of use of various evaluative dimensions at the NPD gates. Our results show that while the market acceptance dimension permeates evaluation at all the gates in the NPD process, the financial dimension is especially important during the business analysis gate and after‐market launch. The product performance dimension figures strongly in the product and market testing gates. The importance of our additional set of criteria (i.e., product uniqueness, market potential, market chance, technical feasibility, and intuition) decreases as the NPD process unfolds. Overall the above pattern of dimensions' usage holds true for both countries in which we collected our data, and across firms of different sizes, holding different market share positions, with different NPD drivers, following different innovation strategies, and developing different types of new products. The results also are stable for respondents that differ in terms of expertise and functional background. The results of this study provide useful guidelines for project selection and evaluation purposes and therefore can be helpful for effective investment decision‐making at gate‐meetings and for project portfolio management. We elaborate on these guidelines for product developers and marketers wishing to employ evaluation criteria in their NPD gates, and we discuss directions for further research. 相似文献

Josef Steindl offers an innovative dynamic analysis of competition in Maturity and Stagnation in American Capitalism, with a key role for technical change. However, in his later writings he suggests that he had not gone far enough and that his account was not ‘sufficiently dynamic’, noting particularly his neglect of fundamental issues in technological development. Here, we critically examine the nature of technical change in Steindl’s analysis, pointing to ambiguities and contradictions that arise. Standard characterizations of the nature of technical change are then introduced and used to further integrate technical change into Steindl’s analysis of competition. 相似文献

The kind, magnitude and distribution of the risks borne by industrialized societies are determined by regulations and the effectiveness of their implementation and enforcement. The authors examine the paradox that the quantified, ‘hard’ risk estimates which provide the scientific basis for the linear model of regulation are, in fact, unrealistic because they are unable to deal with human and organizational influences on regulatory processes. The principal elements of regulation are discussed and placed in a more comprehensive and realistic perspective. 相似文献
