软件缺陷的积累放大效应和软件阶段评审

以典型事例为例，引出软件缺陷独有特性——软件缺陷经逐阶段积累形成的成倍放大特性，列举了软件生存周期各阶段可能引入的软件缺陷和错误，并对可诱发软件缺陷的原因进行分类．详细叙述软件生存周期为传统的瀑布模型的软件开发过程的阶段划分、阶段产品和阶段评审内容．通过某运费计算程序的开发过程分析，对软件阶段评审的重要性进行说明，提出认清软件缺陷的特性，加强软件开发过程中的各阶段评审，是提高软件质量的有效方法．

Software Defect Cumulative Magnifying Effect and Phase Review

Based on the typical examples,the software unique defect characteristic,that the software defect is cumulated and magnified is led.The potential software defects and errors in the software life-cycle are listed,and the possible causes resulting in software defects are classified.The phase division,phase products and phase review contents for the software exploitation of the traditional cataract model in the software life-cycle are presented in detail.With the analysis of a transport cost computer program exploitation process,the importance of software phase review is presented,and the idea that recognizing the software defect characteristic and building up the review will be effective on the enhancement of software quality is put forward.
