Develop a detailed description of the evaluation methods. Consider what data will be collected, from whom and using what technique. Describe how the information gathered will relate to the evaluation questions and under what conditions will data be collected. The best evaluation plans will employ multiple methods of gathering similar or complementary information. Evaluation plans can be formative or summarative, with emphasis placed on different issues.
Impact evaluation focuses on questions of causality.
Process evaluation answers questions about how the project operates and documents the procedures and activities undertaken in service delivery. Such evaluations help to identify problems faced in delivering services and strategies for overcoming these problems. They can tell you if your project is doing what you want it to do, in the way you want to do it. They can provide guidance for practitioners and service providers interested in replicating or adapting your strategies in their own projects. Performance monitoring provides regular, consistent data on key project activities and accomplishments.
