In recent years, Web Engineering development projects have grown increasingly complex for and critical to the smooth running of organizations. However, recent studies reveal that a high percentage of these projects fail to attain the quality parameters required by stakeholders. The inadequate consideration of requirements management activities together with the absence of attention to the elicitation and evaluation of requirements and metrics related to certain quality attributes which are of special importance in this kind of systems, such as usability, have proved to be some of the main causes of this failure. This paper attempts to reduce some of the quality failures detected in Web Engineering development projects by proposing the consideration and evaluation of quality attributes from early stages of the development process. The presented approach therefore commences with a reinforcement of the requirements related activities in this discipline, which is carried out by using a requirements metamodel. Once these requirements have been identified, the approach focuses on the extension of the conceptual models used by Web Engineering methodologies with the aim of allowing the explicit consideration of usability requirements along with the evaluation of quality metrics during the design of the system. An example of an application illustrating how the approach can be used, along with the automatic support which was developed for it, are also shown.
