Usability Dimensions and their impact on Web-Based Transactional Systems Acceptance: an Empirical Examination

Abstract

The article has two fold purpose; it proposes a revised technology acceptance model which includes usability dimensions and then tests revised model by measuring user acceptance of web-based transactional systems (WTS). Model was tested and validated through data obtained from 301 online users. The results suggest that the two important tenets, usefulness and ease of use have significant influence on intention to transact. Response time was found to have an effect on perceived usefulness. Accessibility and navigability had shown significant impact on perceived ease of use. Overall, results supported the proposed hypothetical model.
