Abstract:
Acceptance theories have been used in traditional information systems to help predict and explain their
adoption. In recent years, researchers have attempted to find suitable acceptance models to explain adoption of
mobile information systems as well. In this paper we examine the suitability of the adoption criteria of traditional
models, UTAUT in particular, for mobile information systems in organizations. Other previously proposed criteria
which seem to influence the adoption of such systems are also discussed. A case study of an introduction of a
mobile ordering system in a restaurant is used to achieve these goals. Analysis of the reasons behind individual
employees' decisions to use or reject the mobile device system helps to understand which criteria are likely to
influence adoption of mobile technology in organizations. As the result of this study, proposed adoption factors
suitable for mobile context include: Effort Expectancy, Performance Expectancy, Facilitating Conditions, Mobility,
Trust, and Enjoyment.
