Data for: Evaluation of Web Usability Requirement Model and Web Application Interface Components

In a web application, being a non-quality requirement, usability has been quite a concern for a product to be more successful and efficient for users in the competitive market. The user-centric design methodology is also based on usability design. Even usability is just a non-functional requirement but usability analysis and design can impact the behavioral requirement of a web application to a great extent. The review and feedback sessions are done during prototype design and sometimes like in the agile XP process during the user interface designing step. A web application is built on a collection of defined HTML controls and components. Our ultimate goal would be to model a guideline of usability requirements for different web application components based on different characteristics of usability like learnability, efficiency, memorability, error recovery, flexibility. In this paper, we have evaluated a composite usability requirements model based on the usability requirement attributes & principals and categorization of the web application components based on web application design and interaction context.
