This study develops a model to help improve the success rates of e-Government projects. In recent years, several e-Government studies have identified many challenges of e-Government initiatives and the critical success factors of such initiatives. Regular audit reviews of project performance provide cost-effective minimization of risks by providing information to management and by helping to take corrective actions in order to ensure a successful project outcome. Despite the potential contributions of audits and risk management to minimize project failure, e-Government and public administration research pay little attention to risk-based project implementation and the specific methods needed to mitigate project challenges. Based on the assumption that project risks are inherent in all phases of the project lifecycle in various dimensions and levels of significance, and that for public sector projects, these risks manifest in four broad categories - stakeholder, institutional, technical and project management risks - the model developed in this research uses a risk-based audit approach to project implementation to provide a comprehensive and methodic tool to systematically improve the success rates of project implementation.
