Several approaches for quantitative evaluation of Web-based applications have proposed test-benches, checklists and tools. In this paper, we propose an evaluation approach that integrates and extends the various approaches proposed in this field. We have developed a list of over than 300 criteria and sub-criteria, which we classified using the ISO/IEC 9126 standard as a guide. These criteria represent a first basis for the development of a hierarchical quality model specific to Web-Based Applications. In order to refine our quality model, we followed a systematic approach using the GQM paradigm. A tool supporting our assessment approach has been developed. With this tool, we conducted an experience on several Web systems. The obtained results were rather encouraging. However, they have shown that more dimensions have to be considered to increase the reliability of our model. As a next step, we introduce a three-dimensional model where the initial model is one dimension. The two others represent respectively the life cycle processes and the Web applications domains.
