We are witnessing unprecedented, swift transformations across all industries in the current era. Advancements in information and communication technology have provided us with a tremendous opportunity for change. Our research delves into the profound impacts of digital transformation, extending beyond the public sector to encompass a variety of fields. The public sector, in particular, is experiencing its own set of transformations and changes. Our research offers an in-depth analysis of digital transformation in the public sector, with an emphasis on the key technologies driving this evolution. These include artificial intelligence and machine learning, the Internet of Things (IoT), cloud computing, big data and analytics, digital twins, robotic process automation, augmented reality, and the metaverse. We thoroughly conceptualize these technologies, assessing their relevance and impact on the public sector. Moreover, we identify the potential challenges and present diverse global examples. Our findings reveal that technologies such as artificial intelligence and machine learning (including Generative AI, ChatGPT, and Google Gemini/Bard), IoT, cloud computing, big data and analytics, digital twins, robotic automation, and augmented reality are pivotal in enhancing or creating new value propositions. These technologies have shown remarkable efficacy in elevating the quality of services between individuals and governmental entities, reducing burdens, boosting efficiency, and profoundly transforming public administration and political science. Moreover, aligning these technologies with institutional requirements is essential for successful transformation. Nevertheless, it is noted that these technologies will also refine the competencies of human resources in public administration. Implemented practices reveal that civil servants need higher expertise and improve their skill sets compared to past benchmarks. Based on these insights, we advocate for higher education institutions and other bodies responsible for public sector human resource development to integrate more practical and theoretical technology-focused courses into their curricula. A comprehensive review of the existing literature indicates a scarcity of studies that holistically investigate these technologies and assess them through the lens of field experts, researchers, and policymakers. Our study addresses this gap and contributes significantly to understanding these technologies’ transformative potential.
