This study examines the complex relationship between e-governance implementation and public service efficiency across diverse socio-economic contexts. Through a comprehensive review of recent literature, the research investigates how digital technologies reshape government operations and citizen interactions. The analysis reveals that while e-governance generally leads to improvements in service delivery, cost reduction, and increased transparency, these benefits vary significantly based on factors such as technological infrastructure, digital literacy, and specific service domains. The study challenges assumptions about immediate efficiency gains, particularly in developing countries where initial costs may increase due to the need for parallel traditional systems. The research emphasizes the importance of context-specific approaches, continuous evaluation, and addressing digital divide issues for successful e-governance implementation. These findings contribute to a nuanced understanding of e-governance's impact on public service efficiency, offering valuable insights for policymakers and public administrators navigating the digital transformation of government services.
