Measuring what matters

The paper Measuring What Matters reinterprets OECD-DAC criteria through a systems lens, introduces a practical framework for assessing progress in complex system contexts, and proposes ways to design evaluations that reflect the realities of systemic change. Evaluating WASH programmes has traditionally focused on measuring tangible outputs and service-level outcomes. However, systems strengthening programmes require a different evaluative lens—one that can capture long-term change in how institutions, behaviours, and structures interact. The paper Measuring What Matters shares key insights from the evaluation of Welthungerhilfe's Global WASH Programme, which applied a systems strengthening approach across four countries. The paper reinterprets OECD-DAC criteria through a systems lens, introduces a practical framework for assessing progress in complex system contexts, and proposes ways to design evaluations that reflect the realities of systemic change.
