Technology adoption Theories

The researchers in the field of Information system and technology have analysed the models and theories correlated to comprise ability to forecast and explain (Venkatesh et al, 2003). In areas of IS, the study and use of adoption is regarded as a mature area of research (Venkatesh et al., 2003; Benbasat and Zmud, 1999; Hu et al., 1999).

Over a period of nearly thirty years, there have been many researchers adopting, modifying and validating many theories to understand and determine technology use and acceptance (Venkatesh et al., 2003; Benbasat and Zmud, 1999; Huet al., 1999).

The use of information technology is primarily an intentional behaviour which is impelled by conscious decisions to act (Guinea and Markus, 2009). , it is not surprising that studies adopting information technology could utilize intention-based models that include the Theory of Reasoned Action (TRA) (Fishbein and Ajzen, 1975); the Theory of Planned Behaviour (TPB) (Ajzen, 1991; 1988; 1985; Ajzen and Fishbein, 1980); the Technology Acceptance Model (TAM) (Davis, 1989; Davis et al., 1989); and the Diffusion of Innovation Theory (DOI) (Rogers, 1995;Venkatesh et al., 2003).

This made Venkatesh et al., (2003) to consider, discuss and incorporate elements across the eight evident user acceptance models (TRA, TAM, the Motivational model, TPN, a model combining the Technology acceptance model and the TPB; MATH, DOIand the Social cognitive theory) that showed an outcome to propose the Unified Theory of Acceptance and Use of Technology (UTAUT) (Venkatesh et al., 2003). Few of these theories are considered and believed to have vigorous action signifying the description of IT/IS adoption behaviour (ibid).
