This document provides an overview of project implementation. It discusses that project implementation involves putting the project proposal into action by converting project inputs into outputs. The key phases of implementation are project activation, which makes arrangements to start the project, and project operation, which transforms inputs into outputs. Implementation is usually led by an implementing agency, and other supporting organizations are considered cooperating agencies. An important part of implementation is developing a project implementation plan that outlines the schedule, organizational structure, financial management, reporting, and sustainability. Factors like political commitment, community involvement, and good management can influence whether a project is successfully implemented or not.
