Early Usability Patterns in the Conceptual Model

Abstract

The Internet has increased the development and use of applications in the web environment. However, not all web applications are successful in the market. Many systems are developed with usability flaws, which are very expensive to fix once the system is built. The usability of an information system determines the degree of satisfaction that a user experiences when interacting with it. For this reason, Usability is strongly linked to the software life cycle and it is necessary to incorporate it as a quality characteristic to take into account throughout the development process. One way to achieve this goal is through usability patterns. Information Systems Engineering has increased the use of patterns in the conceptual modeling of systems to ensure that no mistakes are made and use good learned practices. The following proposal shows a set of usability patterns that can be incorporated early into the conceptual modeling of systems, to guarantee the presence of certain usability criteria from the requirements elicitation stage.
