Therefore, “examine the adoption and usage of information technology from a DOI perspective”
(Taylor and Todd, 1995b: 145).
Furthermore, when it comes to perceived behavioural control (PBC), in this model it is decomposed
into 2 constructs, which are self-efficacy and facilitating conditions. “PBC reflect beliefs regarding
access to the resources and opportunities needed to perform a behaviour” (Taylor and Todd, 1995a:
139). “The IT literature demonstrates that PBC may be an important determinant of usage” (Taylor and
Todd, 1995b: 150).
Self-efficacy is “an individual's self-confidence in his/her ability to perform a behaviour” (Taylor and
Todd, 1995a: 139). In another way, self-efficacy is the “degree of confidence the adopter has in her/his
ability to make use of the innovation” (Taylor and Todd, 1995a: 144).
On the other hand, facilitating conditions “reflects to the availability of resources needed to engage in a
behaviour” (Taylor and Todd, 1995a: 139). Resources here are “money, time or technology that is
needed to make use of the innovation” (Taylor and Todd, 1995a: 144).
The other model [see figure 2.6] combined Technology Acceptance Model (TAM) with TPB.
Furthermore, in this model the subjective norm has also been decomposed, Taylor and Todd (1995b)
argued that influences from superiors and peers are not necessarily the same and are also important to
look at because of the positive / negative effect it could create. Finally, facilitating conditions have also
been decomposed to differentiate between resource (i.e. money and time) and technology.
