Fig. 6.11 Social in uence model (adapted from Vannoy and Palvia 2010 )

Since users are now increasingly involved in the development of technology,
practitioners need to be aware of this rising engagement with all processes of
technology creation and adapt the models they use to assess technology adoption.
Furthermore, the impact that social computing is having on conventional business
models represents a change in product development that needs to be carefully
monitored and addressed in order to respond to the needs and trends of people ' s

usage of technology (Vannoy and Palvia 2010 ).
The SIM has been often elected as the primordial model when the behavior
comes from a group or it happens collectively. This model widened the scope of
social in '

notion of subjective norm, which equaled social pressure (Cheung and Lee 2010 ).
However, one of the shortcomings of the SIM is the fact that other than arguing that
people will act according to their peers, this model does not offer a well-de

uence on behavior intention, which was initially limited to other models

6.12 Uni ed Theory of Acceptance and Use of Technology

(UTAUT)

Venkatesh et al. ( 2003 ) proposed an entirely new approach to the evaluation of
technology usage, essentially combining elements of various research frameworks:
TRA, TAM, motivational model, TPB, combined TAM-TPB, model of PC utili-
zation, IDT, and SCT. The new model was named the uni

ed theory of acceptance
and use of technology (UTAUT), and it was empirically validated with six
