To understand technology adoption at individual level, behavioral models such as the theory of reasoned action, the theory of planned behavior, and the technology acceptance model should be applied. While this classification of organization level theory and individual level theory is generally accepted, it also leads to the difficulty of how to ...
Several of the factors in the Webreep model share similarities to existing information systems models. Notably, ease of use features in the technology acceptance model [4] (TAM) and unified theory of acceptance and use of technology [5] (UTAUT), and trust features in Gefen and Karahanna's trust and TAM integrated model.
