In the digital era, the integration of ICT policies and e-Governance has emerged as a critical driver for public sector modernization. ICT policy sets the groundwork for effective e-Governance systems by enabling the digital transformation of government functions and services. However, the realization of e-Governance goals faces significant challenges, particularly in fostering inter-governmental cooperation. These challenges arise from varying policy frameworks, technological disparities, and governance structures across different levels of government. In this context, navigating the intricacies of inter-governmental relationships is essential to ensure seamless information exchange and collaborative governance. The evolving digital landscape introduces both opportunities and complexities, particularly in terms of data privacy, cybersecurity, and digital inclusion. This paper presents a comprehensive review of ICT policies and e-Governance frameworks, with a focus on overcoming inter-governmental challenges in the digital era. Our methodology includes a scoping review of key studies and case analyses, such as the work of Obi (2007) on global perspectives of e-Governance [Obi, T. (2007). E-Governance: A Global Perspective on a New Paradigm], Prasad (2012) on India’s ICT policy for digital democracy [Prasad, K. (2012). E-Governance Policy for Modernizing Government through Digital Democracy in India], and Manda (2017) on South Africa’s smart governance approach [Manda, M. I. (2017). Towards “Smart Governance” through a Multidisciplinary Approach to E-Government Integration]. The findings highlight the importance of fostering interoperable and inclusive e-Governance systems to navigate the inter-governmental challenges posed by ICT adoption. Key implications for policy include the need for harmonized digital policies, the development of interoperable infrastructure, and the emphasis on inclusivity to bridge the digital divide. The results underscore the need for collaborative frameworks that enable effective governance across multiple levels of government, thus ensuring that the digital transformation of public services benefits all stakeholders.
