Impact of Strategic Type on Success Measures for Product Development Projects*

Does the strategic type of firm affect which success measures should be used for product development (PD) projects? This paper theorizes that it should and finds that it does because the PD projects undertaken are usually an expression of the strategic type of the firm. The purpose of this research is to affirm a 1996 survey of members of the Product Development & Management Association (PDMA) that proposes that firms' PD performance measures should vary by their strategic type. Thus, for example, prospectors, the strategic type most likely to introduce new products to new markets, should place greater importance on PD success measures consistent with their characteristic strategies of changing product lines and early market entry. In contrast, defenders, the strategic type most likely to maintain stable product lines for existing markets, should place greater importance on PD success measures consistent with their characteristic strategies of stable product lines and market penetration. Analyzers, a hybrid type between prospectors and defenders, should prefer measures consistent with their characteristic strategies for improving products and being early followers in newer markets. To relate strategic types to specific success measures for PD projects, this paper proposes a model of the relationship based on the degree of project newness to the firm and then catalogs measures of PD project success and groups them according to degree of project newness. The research findings are based on survey responses from 222 individuals who are employed by financial service providers, who identified their firms by strategic type and rated the importance of PD success measures to their firms. The importance of 21 performance measures is compared by strategic type to find significant differences among prospectors, analyzers, and defenders. This research finds several significant relationships. prospectors, for example, attach greater importance to customer satisfaction, launch timeliness, and product return on investment, all of which may be characterized as relating to a higher degree of project newness to the firm. defenders and analyzers, on the other hand, attach more importance than prospectors to measures of unit volume, cost reduction, and margin goals, all of which relate to a lower degree of project newness to the firm. In short, because prospectors seek to introduce new products to new markets, they consider important those measures, which accord with greater product and market newness. The major conclusion of this paper is that strategic type affects the importance of project performance measures and that all firms should not use the same success measures. Firms should contextualize their success in PD projects based on their strategic type. This conclusion resonates with previous findings that strategy is a key determinant of PD success, though it is infrequently included in PD success studies. This paper, therefore, challenges the implicit assumption in the mainstream of PD success literature that success can be determined without regard to firm strategy.

Creative Thinking Ability, Cognitive Type and R&D Performance

The purpose of this study was to investigate the contributions of creative thinking ability and cognitive type to research and development (R&D) performance. One hundred and six researchers in an R&D institute of a petroleum company in Taiwan were given the Circle Test of the Torrance Test of Creative Thinking and Myers-Briggs Type Indicator . Their R&D performance was measured in terms of assigned technical reports, completed service projects, published papers, and a supervisor's performance rating. Results showed that there was a low but positive correlation between creativity and the first-authored paper and the technical report. The cognitive type was on the other hand associated with the performance rating and the first-authored service project assignment. Implications for R&D management are discussed.     

资源型城市融资平台风险分析与化解办法

地方融资平台是地方政府性债务融资的重要渠道之一,为促进地方经济建设做出了重要贡献。但是自金融危机后,地方融资平台经历了5年疯狂的发展,积累了大量风险,已经严重威胁到我国经济的稳定运行。尤其在资源型城市,由于其产业结构单一、城市基础设施匮乏、环境破坏严重等原因,政府负担的城市发展任务更重。所以在经济增长速度逐渐放缓,能源储量逐渐减少的情况下,资源型城市的财政状况更是逐渐恶化。以地方性债务为切入点,逐步分析地方融资平台的风险,最后给出化解地方融资平台风险之道。     

Entry Effects on Cartel Stability and the Joint Executive Committee

We extend Green and Porter's (1984) model to considerentry, by studying twoalternative types of incumbent firms' post-entryreactions: cartel breakdownand accommodation of the entrants. We show thatcooperation is more unstableif entry costs are low and if incumbents accommodatethe new firms. We thentest the applicability of the theoretical model tothe type of collusionthat characterizes the nineteenth-century railroadcartel in the US. Theresults provide support for the model predictions.In particular, cartelstability has been found to be negatively correlatedwith the number of firms in the agreement.
