UR-WSDM : Adding User Requirement Granularity to Model Web Based Information Systems

In this position paper we argue that the overall development of a Web based Information System can substantially bene t from adopting a user-centered design approach. Such an approach is characterized by an analysis phase identifying relevant user classes around which design and development are subsequently organized, as opposed to being driven by the site's data only. We suggest a further improvement on this design method by de ning user classes through a ner level of granularity made out of user requirements. We claim this improves both the overall clarity of the models and their suitability for maintenance and reuse.
