一个全面的可用性模型
A Comprehensive Model of Usability
摘要：
可用性是成功软件系统的一个关键质量属性。不幸的是，对影响可用性的因素及其相互关系没有共同的理解。因此，缺乏设计、分析和改进用户界面的综合基础。本文提出了一个二维模型的可用性相关联的系统属性与用户进行的活动。通过分离活动和属性，可以识别声音质量标准，从而促进关于其相互依赖性的陈述。该模型基于经过测试的质量元模型，可促进精确性和完整性。一个案例研究演示了这种模式的方式，在揭示现有的可用性标准的矛盾和遗漏的援助。此外，该模型还可作为整个质量保证过程的中央结构化知识库，例如自动生成指南文件。
英文摘要：
Usability is a key quality attribute of successful software systems. Unfortunately, there is no common understanding of the factors influencing usability and their interrelations. Hence, the lack of a comprehensive basis for designing, analyzing, and improving user interfaces. This paper proposes a 2-dimensional model of usability that associates system properties with the activities carried out by the user. By separating activities and properties, sound quality criteria can be identified, thus facilitating statements concerning their interdependencies. This model is based on a tested quality meta-model that fosters preciseness and completeness. A case study demonstrates the manner by which such a model aids in revealing contradictions and omissions in existing usability standards. Furthermore, the model serves as a central and structured knowledge base for the entire quality assurance process, e.g. the automatic generation of guideline documents.
