Reuse of a Usability Functionality Implementation in Web Applications

AbstractSoftware system usability is recognized as a quality attribute related not only to the user interface but also to applications design. In this paper we analyse the feasibility of designing and programming reusable solutions for implementing usability features that have a major impact on design. We develop case studies to find common application scenarios, responsibilities, classes, methods, attributes and chunks of code, which we use to propose reusable solutions specified as patterns. In this paper we report the results for the progress feedback usability functionality
