The use of information systems (IS) in the public sector has significantly increased, especially with the introduction of the electronic government system (EGS), which makes it easier for citizens to access government services. Even though there has been a lot of investment in information technology (IT), it's still unclear how much these investments improve productivity. This study thoroughly examines research papers, journals, and conference reports from the past ten years to assess the effect of information systems on the performance of government workers in different areas. Following the reporting standard for systematic evidence syntheses (ROSES), a detailed search was conducted using databases such as Web of Science and Scopus. The study uses the PICo (population, interest, and context) strategy to identify key areas of focus, such as Skill development, return on investment (ROI), strategic decision-making, and innovative thinking. This research plays a crucial role in developing policies and guiding the deployment of information systems to enhance the effectiveness of government officials and other stakeholders. It also looks into factors and situations that might improve or weaken the impact of IS on performance in government contexts. The outcomes of this systematic review help in understanding the complex relationship between information systems and the performance of government workers more clearly. The findings provide valuable guidance for policymakers, government organizations, and scholars, offering strategies to make the most of information systems to improve government workers' performance and productivity.
