ABSTRACT: The digital economy has forced organisations to spend a bigger percentage of their budget on information technology (IT). This technology is acquired to support not only the operational but also the strategic objectives of the organisations. For some organisations, acquiring the technology is a straightforward task as compared to making their workers use the technology. The same also goes to organisations that attempt to introduce new IT products or services. The technology introduced to the market can be potentially marketable through research and development’s lenses but not to the endcustomers. Whether we look at the perspective of users in the organisation or of end-customers, the acceptance from the users is a crucial prerequisite that will ensure the success of the technology to be adopted. The purpose of this chapter is to provide an overview of existing theories and research findings utilizing these theories in individual acceptance of information technologies.
