2Technology Acceptance Model 1989Technology Acceptance ModelThe Technology Acceptance Model (TAM) is an information systems theory that models how users come to accept a technology and how they use that technology.Developed by Fred Davis in 1989
3Fred DavisFred D. Davis’s 1989 articles in MIS Quarterly and Management Science are the most highly cited articles in those journals.Davis is listed in ISI HighlyCited.com, which features “the world's most influential researchers”.

71975 Acceptance Models Theory of Reasoned Action (TRA) TRA suggests that a person's behavioural intention depends on the person's attitude about the behaviour (“Would I do this sort of thing normally?”) and subjective norms (“Would other people in the group do this?”).

101985 Acceptance Models Theory of Planned Behaviour (TPB) Extension of his Theory of Reasoned Action (TRA), since TRA states that actual behaviour is highly related to behavioural intention, but the results of some studies show that, because of circumstantial limitations, behavioural intention does not always lead to actual behaviour.
111985 Acceptance Models Theory of Planned Behaviour (TPB) TPB adds the notion of Perceived behavioural control which refers to a person’s perceptions of their ability to perform a given behaviour.

131995 Acceptance Models Decomposed Theory of Planned Behaviour (DTPB) developed by Taylor and ToddLike the TPB but decomposes the attitudinal, normative and control beliefs into multidimensional constructs, which provides more explanatory power, better diagnostic value and strengthens the ability of the model to explain behavioural intention.

17Technology Acceptance Model 1989Technology Acceptance ModelWhen users are presented with a new technology, two key factors influence their decision about how and when they will use it:Perceived usefulness (PU) - the degree to which a person believes that using a particular system would enhance his or her job performance.Perceived ease-of-use (PEOU) - the degree to which a person believes that using a particular system would be free from effort.
