This book focuses on the evaluation of information projects, products and services from a learning perspective. It looks at evaluation within the context of the overall project cycle, from project planning and implementation to monitoring, evaluation and impact assessment, and then at the evaluation process itself, the tools involved and examples of their application. The theme running throughout the toolkit is: Participatory evaluation for learning and impact. The emphasis is on internal evaluation -- or 'self-evaluation' -- rather than external evaluation. Internal evaluation contributes to organisational learning and represents a significant shift from traditional evaluation, which has tended to be donor-driven to meet the demand for accountability and compliance. If evaluation is to achieve its ultimate objectives of enhancing learning and demonstrating impact, it needs to be applied with confidence in a systematic and coherent way.
