A Review of Technology Acceptance Models and Theories

In the contemporary world, technology and information systems are perceived as mandatory aspects for many organisations and companies to attain their goals. Thus, several technology theories and models have been formulated and adopted in various fields to increase the usage of technology. Many studies have adopted different models and theories to examine the factors that can affect and lead to the successful utilisation of technology. Therefore, through a critical review of the literature, the current study aims to critically discuss the strengths and limitations of some of these technology acceptance models, namely technology acceptance model, theory of reasoned action, unified theory of acceptance and use of technology and extended technology acceptance model. Based on the review, this study illustrates that no theory is free from limitations and that each theory has both strengths and weaknesses. This study offers future researchers an opportunity to adopt a suitable model for performing their empirical studies with different technologies.Index Terms—TAM, TRA, UTAUT, technology, technology acceptance model, theory of reasoned action.
