This research article explores the factors influencing the development and implementation of periodic plan, strategic plans, and the Medium-Term Expenditure Framework (MTEF) in local governments of Nepal, particularly focus on Bharatpur Metropolitan City. The study adopts a qualitative research design, employing document analysis, focus group discussions, and interviews with key stakeholders, including government officials, local communities, NGOs and civil societies. The findings identify key determinants: public responsible governance; efficiency, financial integrity, and systematic implementation of programs; proper resource allocation; and risk identification and management. Major findings emphasize the importance of public responsible governance, which includes public voice, participation, and shared responsibility in decision-making processes. Additionally, the study highlights the necessity of efficiency, financial integrity, and systematic implementation of programs for effective service delivery. Proper resource allocation and risk management are also crucial, ensuring that development projects meet community needs and sustainable goals. These elements collectively contribute to the successful governance and development of local governments in Nepal. The research also highlights the need for further studies, particularly in other regions of Nepal, using diverse methodologies to strengthen the understanding of local-level planning and its implications.
