Métodos de Evaluación de Usabilidad para Sistemas de Información Web: Una revisión

Este artículo presenta una revisión de modelos de usabilidad web, así como de sus métodos de evaluación (Usability Evaluation Methods, UEMs) más relevantes y basados en las publicaciones de artículos académicos durante los últimos veinte años. Se ha realizado un análisis descriptivo de las dimensiones que componen los diferentes modelos de usabilidad, así como un análisis de sus métodos de medición. Luego se describen la estructura general y las características de los Sistemas de Información basados en la Web (WIS). En seguida se analizan los diferentes UEMs, su clasificación y métodos específicos. Se termina con las conclusiones sobre el estudio realizado.Abstract. This article presents an overview of the models of web usability and usability evaluation methods (Methods of Evaluation UEMS) more relevant and based on academic articles published during the last twenty years. Has been made a descriptive analysis of the dimensions that compose the different models of utility as well as an analysis of the measurement methods. Here, we describe the general structure and characteristics of information systems based on Web (WIS). Then we analyze the different UEMS, classification and methods. It ends with the conclusions of the study

User-Website Interactive Communication Analysis in Web-Based Information System Development

Abstract- Web-based information systems (WBIS) include the website part and the system part, and easy-to-use website is particular critical to the success of WBIS. This paper argues that the easy-to-use website can only be developed based on the need of use in the user perspective and such need must be captured and modelled as communicational requirements in WBIS analysis. However current analysis and modelling techniques do not enable modelling of communicational requirements in WBIS development. This chapter addresses this problem and proposes a new modelling technique (dialogue act modelling technique) for modelling of communicational requirements by user-website interactive communication analysis. It shows that the user-website interactive communication model built for the website part of WBIS by the analysis is also useful in modelling of the system part of WBIS with object orientation. It concludes that user-website interactive communication analysis is significant in developing WBIS towards easy to use and interaction

Developing web-based information systems for emergent organisations through the theory of deferred action: Insights from higher education action research

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.This investigation follows a philosophically interpretive approach on how the web developer developed Web-based Information Systems (WBIS) in a continuously changing higher education organisation. The investigation focused on emergence within the organisation and the resultant problems this gives the web developer in developing WBIS. The web developer used an action research methodology to investigate the emergent higher education organisation and its need for web-based aesthetics & internet speed. This approach was designed by the action researcher to assist both the web developer and manager in developing WBIS within emergent organisations. It is also designed to address a number of major constraining factors placed on the web developer. These included: time constraint, web-based aesthetics, internet speed, emergent aspects, methodology issues and accommodating planned organisational change. The interpretation of these constraining factors gained through the theory of deferred action enabled the action researcher to understand, interpret and create associations to explain the WBIS development process. The web developer had to defer the design process at several points because of unexpected events occurring in the organisation and take deferred action. As a result the Kadar Matrix was created and used by the web developer to manage the constraining factors. The Kadar Matrix has extended the theory of deferred action (ToDA) by implementing its constructs in the analytical tool, Kadar Matrix, for WBIS development. This is a modification of theory for practice. The research further identified that deferred action is necessary for the web developer in emergent organisations
