Abstract: A kind of new software defect analytical method on the basis of orthogonal classification is presented. At first, proposed to apply orthogonal classification to software defect measurement. Secondly, a typical defect orthogonal classification model is set up for telecommunication equipment manufacturing enterprise, supposing tools and application instance is given. In the end, workflow system of software defect tracing based on orthogonal classification is set up to support the defects collecting, tracing, dealing and analyzing for enterprises. Compared with traditional method, this method not merely has the advantages of popularity, haleness and low cost but the accuracy of identifying the defect improves notably, thus it offers strong support for the prevention of defects in software procedure.

摘要： 以软件缺陷为研究对象，提出基于正交分类的软件缺陷度量分析方法。为此，首先提出将正交分类法应用于软件缺陷度量；其次，建立了典型的电信设备制造行业软件缺陷正交分类参考模型，并给出了支持工具和具体的应用实例。最后，通过构建基于正交分类的软件缺陷跟踪工作流系统来支持不同企业对缺陷的收集、跟踪、处理和分析。与传统方法相比，扩展正交分类方法不仅具有普适性、健壮性、低成本的优点，而且缺陷定位的准确性和精确性显著提高，为CMM中的缺陷预防提供了有力的支持.
