Usability is increasingly recognized as an important quality factor for interactive software systems, including traditional GUIs-style applications, Web sites, and the large variety of mobile and PDA interactive services. Unusable user interfaces are probably the single largest reasons why encompassing interactive systems – computers plus people, fail in(More)
This paper examines current approaches to usability metrics and proposes a new approach for quantifying software quality in use, based on modeling the dynamic relationships of the attributes that affect software usability. The Quality in Use Integrated Map (QUIM) is proposed for specifying and identifying quality in use components, which brings together(More)

Usability is now well accepted by developers as an ultimate quality factor. However, most of the existing usability evaluation methods require a fully functional prototype. Tests are also conducted after the development in specific costly lab which may results in significant maintenance costs. This paper introduces a set of novel metrics-based prediction(More)
