一、引言新产品成败问题是一个复杂的问题。长期以来,国内外对新产品的成败进行了大量的研究,其中有规范分析、案例分析和统计实证分析。新产品开发的成败调查,是寻求成败原因的根本途径。运用现代统计分析方法,深入到各个具体的影响因素上蒐集第一手信息,并根据其科学的统计推断来诊断产品开发成败的原因。每一个调查表是对企业产品开发成败的系统反思和总结,数份调查表可叠加出新产品开发的成功轨迹或失败烙印。1979年,加拿大McMaster大学教授Robert Cooper在因素调查的基础上,通过建立数学模型来分析,成功地研究了103家加拿大公司 First, the introduction of success or failure of new products is a complex issue. For a long time, lots of researches have been done on the success or failure of new products at home and abroad, including normative analysis, case analysis and statistical empirical analysis. Success or failure of new product development survey is the root cause of the success or failure of seeking the root cause. The use of modern statistical analysis methods, deep into all the specific factors to collect first-hand information, and according to their scientific statistical inference to diagnose the causes of product development success. Each questionnaire is a systematic reflection and summary of the success or failure of enterprise product development. Several questionnaires can add up the success track or failure of new product development. In 1979, Robert Cooper, a professor at McMaster University in Canada, analyzed the factors and established mathematical models to successfully study 103 Canadian companies
