This study develops and empirically tests a research model to comprehensively examine factors influencing the success of the mobile office (i.e., adoption) in business. In particular, this study proposes an integrated theoretical framework that combines the theory of planned behaviour (TPB) and the perspective of perceived value. By doing so, it aims to examine not only fundamental determinants of an information system (IS) adoption proposed by TPB (i.e., attitude, subjective norm, and behavioural control) but also various psychological and emotional factors that determine users' attitude towards IS through the perspective of perceived value. The results indicate that perceived value, colleague opinion and self-efficacy are critical antecedents that increase users' intention to adopt new technology. Furthermore, perceived usefulness and social image are the salient drivers of mobile office adoption because they increase users' value; on the other hand, performance risk and psychological risk are the salient barriers to adoption because they reduce users' value.
