Top manager‘s support refers to whether or not the top
managers understand the nature and functions of HIS
innovation and therefore fully support the development of it
(Lian, Yen et al., 2014). According to recent review of IT
adoption literature by Jeyaraj et al. (2006), top management
support is one of the three best predictors for IT innovation
adoption by organizations. In the healthcare domain and
context of HIS, top management found to be crucial for the
introduction of PACS (Chang, Hwang et al., 2006). They
emphasized, top management support critically affects the
decision for the PACS adoption.
