Abstract | This paper describes the development of multi-item scales for measuring user perceptions of the ease-of-use and of the (hereafter ), incorporating a system task focus into the scales dimensional structure (e.g. how easy or useful the is for information search, communication and or purchasing). The items are tested on 2077 users recruited using a survey, revealing four factors for each scale. Perceived ease of use consists of learning, search and find, transaction and communication ease, and perceived usefulness consists of communication, purchase, information search and acquisition, and access to quality products and information. A regression analysis on usage frequency shows how easy users find it to learn how to use the and how useful the is for purchasing are the best predictors of how frequently they will use the . These results highlight the importance of training users how to effectively use hypermedia-based systems like the , and the design of systems that are easy to navigate and that provide advanced functionality for transactional activity.
