Patrones de usabilidad temprana en el modelo conceptual

Abstract

Internet ha incrementado el desarrollo y uso de aplicaciones en entorno web. Sin embargo, no todas las aplicaciones web tienen éxito en el mercado. Muchos sistemas son desarrollados con fallas en la usabilidad, que son muy costosas de arreglar una vez que el sistema fue construido. La usabilidad de un sistema de información determina el grado de satisfacción que experimenta un usuario al interactuar con el mismo. Por este motivo, la Usabilidad está fuertemente ligada al ciclo de vida del software y es necesario incorporarla como una característica de calidad a tener en cuenta, durante todo el proceso de desarrollo.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.
