根据用户需求选择软件包是软件工程的核心任务。选择不合适的软件包可能会损害业务流程，并可能对相关组织的运作产生负面影响。由于许多因素，软件包选择的成功受到威胁，其中最重要的因素之一是缺乏对软件包功能和用户质量要求的结构化描述。在本文中，我们提出了一种使用 ISO/IEC 质量标准作为框架来描述软件包质量因素的方法。遵循此标准，特定软件领域的相关属性被识别并构建为层次结构，并选择它们的度量。然后可以以统一且全面的方式描述该领域中的软件包。因此，可以通过将用户质量需求转化为以质量模型属性表达的需求来改进包的选择。我们通过深入介绍邮件服务器域的质量模型来说明该方法。
Selection of software packages from user requirements is a central task in software engineering. Selection of inappropriate packages may compromise business processes and may interfere negatively in the functioning of the involved organization. Success of package selection is endangered because of many factors, one of the most important being the absence of structured descriptions of both package features and user quality requirements. In this paper, we propose a methodology for describing quality factors of software packages using the ISO/IEC quality standard as a framework. Following this standard, relevant attributes for a specific software domain are identified and structured as a hierarchy, and metrics for them are chosen. Software packages in this domain can then be described in a uniform and comprehensive way. Therefore, selection of packages can be ameliorated by transforming user quality requirements into requirements expressed in terms of quality model attributes. We illustrate the approach by presenting, in some depth, a quality model for the mail server domain.
