“…With regard to the presented results, it is reasonable to conclude that this study expands the existing research on the SIS provided by Schauer [7], Fuchs [1], [2], Hilty et al [4], [5], Guillemette, Paré [14, [15], and Curry and Donnellan [12], [13] by presenting the levels of ICT adoption and sustainability as well as identifying how the ICT adoption influence sustainability. The research outputs are also complementary with findings related to the effect of ICT adoption on sustainability in enterprises [21], [22], [23] and households [48]. Summarizing up-to-date research findings, it can therefore be concluded that the ICT quality, ICT management, and information culture within enterprises and households have a significant impact on sustainability, whereas in government units only the ICT quality and information culture influence sustainability.…”
