Usability is a fundamental type of non-functional requirements (NFRs) that specifies how easy, efficient, error-preventing, and pleasant a software system must be to be used by human users. The importance of usability is increasingly pervasive in the modern software engineering projects. Because of the unique characteristics of usability NFRs, however, software development teams often experience considerable challenges in managing this type of NFRs, limiting their ability in creating more successful products for their users. First, usability and user interaction are complex issues that rely on diverse factors that require effective collaboration from multidisciplinary software development stakeholders, which is usually difficult to achieve. Second, resource and skill-demanding activities such as iterative prototyping and user studies are indispensable in identification, evolution, verification, and validation of usability NFRs. There is currently little methodology and tool support in facilitating the multidisciplinary collaboration and the iterative activities in managing usability NFRs. The long-term objective of this research program is to address this gap by investigating, developing, and deploying methods, models, and tools for usability NFRs management in collaborative and iterative environments. In the next five years, this research targets five short-term objectives: (1) accumulating practitioners' knowledge about usability NFRs management, (2) constructing a taxonomy and an ontology of usability “bad smells” as a common vocabulary for discussing usability concepts, (3) creating a usability NFRs modeling scheme to support multidisciplinary communication, (4) exploring semi-automated methods for usability NFRs identification and construction, and (5) creating and evaluating a usability NFRs lifecycle management tool. To achieve these objectives, we (my students and I) will work closely with industrial practitioners in order to measure the impact of our findings in practice. This research is motivated by and extends my recent work on techniques to support software stakeholders' collaborative consideration on usability and user experience issues in serious games and other domains. The outcomes from this research program will increase our theoretical and practical knowledge about usability NFRs, broadening the adoption of usability engineering, especially in areas in which usability is becoming an emerging concern. The methods, models, and tools resulted from this research will directly benefit the Canadian industry, allowing companies to streamline their usability engineering process and create more successful products. Last but not least, this research program will train four HQPs, including two PhD and two Master students, allowing them to gain extensive hands-on experience in empirical research and user-centered design and development.

可用性是一种基本类型的非功能需求（NFRs），它指定了一个软件系统必须是多么容易、有效、防止错误和令人愉快才能被人类用户使用。在现代软件工程项目中，可用性的重要性越来越普遍。然而，由于可用性nfr的独特特征，软件开发团队在管理这种类型的nfr时经常遇到相当大的挑战，限制了他们为用户创建更成功产品的能力。首先，可用性和用户交互是依赖于不同因素的复杂问题，这些因素需要多学科软件开发涉众的有效协作，而这通常很难实现。其次，资源和技能要求的活动，如迭代原型和用户研究，在可用性nfr的识别、演进、验证和确认中是不可或缺的。目前很少有方法和工具支持促进多学科协作和管理可用性nfr的迭代活动。
