Monitoring and evaluation (M&E) is a set of techniques used in project management to establish controls and ensure a project stays on track to achieve its objectives. Monitoring involves systematically collecting, analyzing, and using information for management decisions and control. It provides information to identify and solve problems and assess progress. Evaluation determines the effectiveness, efficiency, relevance, impact, and sustainability of a project. Both monitoring and evaluation are important for project management and should be integrated throughout the project cycle.
