When applied to the acceptance of information technology systems or services, the model contains five concepts. As in TRA, it includes behavioral attitudes, subjective norms, intention to use and actual use. However, this theory interprets behavioral control as a perceived construct. Perceived behavioral control covers both the intention to use and the actual usage. Actual usage is in turn a weighted function of intention to use and perceived behavioral control Under this arrangement control aspects of the observation is introduced into the model. This makes the TPB more functional in its application.
Researchers have used the TPB widely to model the acceptance of a variety of new information technologies in businesses as well as to predict levels of usage. For example, Mathieson (1991) used the TPB as well as the Technology Acceptance Model to predict user's intentions, specifically with respect to the usage of spreadsheets. In another related work, the theory of planned behaviour (TPB) was decomposed by Taylor and Todd (1995) and posits that intention to adopt and use a technology is affected by attitude, subjective norms and perceived behavioural control. There are strengths as well as limitations to the TPB. The main strength of the TPB is that it can cover …show more content…
According to Taylor and Todd (1995), Decomposed Theory of Planned Behavior offers a number of advantages: it is more transparent and is easier to grasp the relations among beliefs, attitudes and intentions, it enables application of the model to a variety of situations and in managerial terms it is more relevant because it helps to determine specific factors that lead to adoption and use of new
