A Systematic Review of UTAUT and UTAUT2 as a Baseline Framework of Information System Research in Adopting New Technology: A case study of IPV6 Adoption

This paper reviews the most recent literature on UTAUT/ UTAUT 2 (Unified Theory of Acceptance, and Use of Technology) by focusing on the findings and recommended future research. To meet this aim, the authors conduct an in-depth analysis of the current literature by using the systematic review method. This research paper is conceptual in origin, and it was supplemented by analysis 65 papers from various websites which hosted scientific journals. These papers employed UTAUT and UTAUT 2 as a baseline framework. The researchers focused on findings in these papers and on the core constructs of UTAUT used to predict behavioral intentions. The results from the previous studies confirmed that the four core constructs of UTAUT/UTAUT2 contributed to understanding of the behavioral intention to accept / adopt or use the technology and the performance expectancy (PE) has significantly correlated with technology adoption. Moreover, the previous studies show that UTAUT 2 has been more explanatory in predicting behavioral intentions and should be used for the future works in adopting any new technology.
