Enterprise Architecture (EA) as a popular approach, has been used in city governments and public sectors to improve consistency among their business goals and ICT implementations. Despite theoretical benefits that have been widely agreed on, challenges have also been met in practice reflecting on issues about techniques, businesses, organizations, processes, and etc. It is not easy to understand the challenges from different perspectives and come up with an integrated solution. In this research, we reviewed nine scientific papers in which projects of applying EA in governments or public sectors in real scenario have been presented. We collected challenges reported in these projects and proposed to observe them by using Technology Acceptance Model (TAM) as a lens. Through this technology acceptance perspective, more than seventy challenges can be understood and organized in a consistent way. The results are expected to bring some in-depth insights and to help practitioners to apply EA in public sectors.
