Applications of Perceived Usefulness and Perceived Ease of Use: A Review

Information Technology (IT) is the buzzword and important topic nowadays, and it is going to be more important with each passing day. As per Technology Acceptance Model (TAM), IT is liked or rejected by people because of two determining variables, Perceived Usefulness (PU) and Perceived Ease of Use (PEOU). TAM is adopted from theory of reasoned action, which affirmed that beliefs, attitudes, intentions and behavior form causal chain among them. PU and PEOU helps in predicting the attitudes of the users towards the technology and computer usage, which further influence their intentions to use and imbibe that technology. This paper carried out a systematic review of the TAM factors i.e. PU and PEOU which influence the consumers' attitude and intentions toward adoption of IT in various applications like online shopping, internet marketing, software, social media advertising, e-banking, education, healthcare etc. This paper highlights the prominence of PU and PEOU in various fields and will establish a strong base for future research based on these factors in adoption of upcoming technologies.
