This literature review addresses the question, "What are the key factors influencing the success (or not) of M&E systems-strengthening interventions in improving the demand, supply and/or use of evaluative evidence?" Drawing on 20 sources that span conceptual frameworks, empirical case studies, and systematic reviews, the analysis proceeds in three stages: first, it examines enabling factors that strengthen demand, supply, and use; second, it analyses hindering factors that impede each dimension; and third, it synthesizes cross-cutting insights for policy and research.
