Abstract: Digital transformation is now central to strengthening public service delivery, yet evidence on how digital strategies collectively improve public sector performance remains fragmented. This study presents a systematic review of digital strategies for enhancing public service delivery systems, with a primary focus on the United States and supporting international insights. Drawing on peer-reviewed literature published since 2015, the review examines e-government platforms, artificial intelligence, smart government technologies, open data initiatives, and broader digital transformation approaches. A thematic narrative synthesis is used to assess implementation practices, outcomes, and contextual conditions shaping effectiveness across levels of government. The findings show that digital strategies can significantly improve efficiency, transparency, accountability, and citizen engagement when they are citizen-centered, strategically aligned, and supported by strong data governance and organizational capacity. Digitalization expands service accessibility, streamlines administrative processes, strengthens evidence-based decision-making, and enables participatory governance. However, these gains are uneven and constrained by persistent challenges, including digital exclusion, organizational resistance, cybersecurity and privacy risks, limited resources, and weak interoperability. Successful initiatives integrate technology with change management, workforce development, cross-agency coordination, and adaptive governance. This review synthesizes fragmented evidence into a coherent framework that informs inclusive, secure, and sustainable digital transformation in public service delivery.
