Still with the huge benefits and synergies that e-Government grants to governments and societies, it faces many obstacles and challenges. Therefore, there are always a number of critical success factors and risks associated with e-Government. This paper highlights some of the key ones;it critically assesses key factors that influence e-Government services adoption and diffusion. Thus, the aim of this study is to examine and identify the factors that influence and affect the utilization of e-Government in the developing countries, specifically in Jordan. Furthermore, this article investigates the challenges and barriers that must be overcome in order to successfully implement e-Government in Jordan. Semi-structured interviews were conducted and used in this study to collect the data. The results of this study show that the most significant challenges and factors influencing the implementation of e-Government services in Jordan are related to budgeting and financial costs, human expertise, social influence, technological issues, lack of awareness, resistance of public employees, data privacy and security, the legal framework, the needed technology, administrative obstacles, and trust or believing in e-Government.
