This paper provides a comprehensive analysis of the implementation of government assurances in Zambia, with a focus on the key sectors of finance, energy, water development, and education. Government assurances represent formal commitments made by government officials in response to parliamentary queries and serve as critical tools for ensuring accountability and transparency in governance. The study primarily examines the 2023 Action-Taken Report (ATR) presented to the National Assembly of Zambia, which details the progress made in fulfilling these assurances. Drawing on Public Accountability Theory, the paper explores how parliamentary oversight mechanisms influence the implementation of public policy, particularly in developing contexts. The research adopts a qualitative approach, utilizing secondary data from the ATR, supplemented by relevant academic literature and government publications. Thematic analysis was employed to identify patterns and recurring themes related to the implementation process, such as financial constraints, bureaucratic inefficiencies, and weak inter-ministerial coordination. Through this method, the study seeks to answer key research questions, including the extent to which government assurances have been implemented, the challenges hindering their execution, and potential strategies for improving the effectiveness of public policy in Zambia. The findings reveal that while progress has been made in some areas—such as the Zambia Growth Opportunities Programme and the Lusaka Sanitation Programme—significant barriers remain. Financial limitations due to Zambia’s debt burden, coupled with delays in international funding, have constrained the government’s ability to allocate sufficient resources for public projects. Additionally, bureaucratic inefficiencies, particularly in procurement processes and inter-ministerial coordination, have led to delays in project implementation, particularly in rural electrification and infrastructure development. In response to these challenges, the paper proposes several recommendations aimed at improving the implementation of government assurances. These include enhancing domestic revenue mobilization to reduce reliance on external funding, strengthening inter-ministerial coordination mechanisms, and reforming procurement processes to improve efficiency. Furthermore, the study highlights the importance of developing robust monitoring and evaluation (M&E) systems to ensure timely tracking of project progress and to improve public accountability. By contributing to the broader discourse on governance and public policy in Zambia, this paper offers valuable insights for policymakers, government officials, and scholars interested in improving the effectiveness of government assurances in developing contexts. It emphasizes the need for comprehensive public sector reform and suggests pathways to strengthen the capacity of government institutions to deliver on their promises, ultimately improving service delivery and fostering public trust in government institutions.
