The development of two tools for measuring the easiness and usefulness of transactional Web sites

The worldwide diffusion of Electronic Commerce shifts the exchange relationship between buyers and sellers from the face-to-face model to the face-to-screen model; and it is, therefore, important for organisations to consider the Web attributes that attract users. Yet, conceptualising, empirically testing, and refining tools for measuring the easiness and usefulness of transactional Web sites are lacking. The present study tries to fill this gap in the literature by describing the development of two tools for measuring perceived easiness and usefulness in a Web context. The findings of exploratory and confirmatory factor analyses reveal that the two instruments demonstrate sound measurement properties and would be useful to organisations interested in setting up an electronic business, and to scholars interested in Web research.
