随着软件规模的日益增大，软件质量问题也日益突出。它不仅决定了软件交付后使用成本的增加和过早退役，而且也是软件开发延期交付、成本飙升，以至于开发失败的主要因素之一。事实上，软件科学和软件工程一直在寻求对软件本质更清晰的认识，试图以更加合理的方法组织和开发软件，在保证高质量的前提下，大量、快速开发软件。所以，各种软件书刊从分析、设计、构造、测试、维护，到管理、配置交付都涉及质量，而且各种构造方法、解决方案、实施规范层出不穷，吸引了从业者大量精力，而直观、系统地介绍软件质量最新研究成果和度量技术的书籍并不多见。本书正是这类较好的图书之一，作者是IBM公司资深研究员StephenH．Kan。 1995年第1版出版后即引起业界广泛关注，第2版在原有13章的基础上增加了当今成熟的软件度量和质量保证技术，如软件测试过程中的度量，面向对象开发中的度量，可用性度量，过程中(in-process)和项目的评估方法，软件过程改进及其功能度量方法，总共达19章。 本书有以下一些特点。 第一，面向工程实践、系统、完整。从软件质量的基本概念开始，介绍度量基本理论，软件开发过程中的各种度量，质量管理，七种基本的质量度量工具，直到上述最新度量方法成果。软件工程实践者可以从中得到直接的帮助。 第二，取材新颖，有一定的学术深度。传统的软件质量度量模型，因其过程编程背景压缩至相当小的篇幅，如McCabe、Halstead模型等，而引入了许多新颖的质量管理与度量模型，如可靠性增长模型，缺陷消除模型等。这些模型有较深厚的概率统计学理论基础，特别对面向对象软件，提供了一批新准则和经验公式，这对研究和开发当前基于构件、Web服务软件的质量度量方法和规范的从业者，无疑是个很好的参照。 第三，本书符合IEEE和ACM 2001年发布的软件工程知识体(SWEBOK)指南。软件质量一章界定的内容，是计算机专业课程体系制定者很好的参考资料。事实上，本书很适合计算机软件、软件工程学科本科生和研究生的教材。 麦中凡 北京航空航天大学软件学院教授
