According to recent studies, an estimated 90% of Web sites and applications suffer from usability and/or accessibility problems. As user satisfaction has increased in importance, the need for usable and accessible Web applications has become more critical. To achieve usability for a Web product (e.g., a service, a model, a running application, a portal), the attributes of Web artefacts must be clearly defined. Otherwise, assessment of usability is left to the intuition or to the responsibility of people who are in charge of the process. In this sense, usability models (describing all the usability sub-characteristics, attributes and their relationships) should be built, and Usability Evaluation Methods (UEMs) should be used during the requirements, design and implementation stages based on these models. Similarly, identifying the set of characteristics that make the Web more accessible for everybody, including those with disabilities is necessary to systematize the way practitioners face accessibility issues.
