Assessing User-Centric Quality of Web-Based Systems

This paper addresses the issue of user-centric quality assessments of webbasedsystems, and proposes an assessment model for quality evaluations byfocusing on metrics based on the perspective of end-users. The model includesan approach which scales quantifiable values of quality attributes based on importanceof users’ perception. The assessment model is applicable to subjectivequality attributes whereas the scaling technique can be ported to a rangeof assessment models. Because the model is based on subjective metrics, itshould be used in conjunction with objective models, particularly those whichreturn quantifiable values for quality ratings. The approach is flexible enough forend-users to tune the model according to their requirements. The web designercan also use this approach to assess the users’ related quality attributes of thesystem.
