Abstract

In the world where information technology (IT) evolves at a rapid pace, the slightest lapses of acceptance of the latest development could mean a drawback for an organization. Information technology plays a vital role in various organizational activities. How well the information system (IS) perceived and integrated into organizational processes, hence, is the primary factor that influenced the level of effectiveness exists in IT use especially at different organizations. Subsequently, it is essential to review the models and theories to further understand the outcomes on perception of IT use in the organization. To optimize use of IT, the appropriate information system level must match the type of technology use on what users perceived. The purpose of this study is to review models and theories used in current research on perceptions of IT use and to understand the determinants on 6 key sectors in organization mainly business, government, education, manufacturing, healthcare and financial institution. The analysis consideration of these models and theories focuses on conceptual and empirical review with significant external variables. Findings indicated that technology acceptance model (TAM) theory, unified theory of acceptance and use of technology (UTAUT) theory and seven principles of good practice in undergraduate education theory are mostly used to examine the perception of IT use in the respective sectors in organization. Furthermore, the significant results shown these models are still relevant to current research. This literature study suggests constructive recommendation for future research work.

Key words: Information technology, perception, technology acceptance model, unified theory of acceptance and use of technology, information system.
