Towards a Cost-effective Evaluation Approach for Web Portal Interfaces

A cost-effective approach for web portal usability evaluation is presented in this paper. Due to specifics of portals as web sites, mainly referring to their structure and media specificities along with diversity of users, tasks and workflows, distinct assessment approaches should be employed. Methodology brings together laboratory-based testing along with experts’ inspection and produces valuable results for users and developers at a low-cost. Compared to our first study, user assessment applied a faster and less expensive procedure, providing stability of measures with reduced sample size, while inspection employed fewer specialists with higher expertise and a simpler evaluation form. Directions of future work are identified.
