Evaluating the performance of business Web sites has been a constant concern of researchers in different fields. This article presents an approach that contributes to the development of a methodology to assist researchers, developers and managers to establish criteria to evaluate and build digital business environments. Based on a multiple case study in three large banks in Brazil, this article proposes and tests a model of three dimensions to evaluate virtual business environments from the user's point of view: functionality, evaluates the offered services profile; reliability, investigates the security of a transactional site; and usability evaluates the quality of user interaction with the site.

The Internet and its World Wide Web service have reshaped the promotion of cultural and tourism products. Well designed and user adaptable e‑commerce websites improve business promotion as they attract more e‑visitors. Multilingualism, dynamic and thus frequently updated content, email communication and searching capabilities are crucial options of websites. In this paper we empirically build an evaluation methodology to assess the technologies and services of Greek e‑tourism and e‑cultural websites. The primary focus of our work is to evaluate the technical capability of tourism and cultural websites and to realize the available options offered to users. A number of tourism e‑commerce websites and e‑museums were randomly selected and their content and technologies were analyzed based on the methodology proposed. The results of this statistical examination are analyzed and discussed. The main conclusion is that although the reviewed websites are rich in multimedia content they need to support customers more efficiently by offering more services or by refining the offered e‑services.

The widespread distribution of HIS requires professional evaluation techniques. In this study we present a usability questionnaire called IsoMetrics which is based on the international standard ISO 9241 Part 10. The questionnaire was applied to assess the usability of a Hospital Information System. The equivalence of the online and a paper‑and‑pencil format of the questionnaire were investigated. The results show that the different formats do not affect the subject's ratings. IsoMetrics was proven to be a reliable technique for software evaluation in the field of hospital information systems supporting usability screenings in large organisations.
