সারসংক্ষেপ	The Logical Framework Approach (Logframe) is a structured planning, monitoring, and evaluation method that distils an intervention into a single four-by-four matrix linking a hierarchy of objectives to the indicators, evidence, and external conditions on which success depends. Originated by Leon Rosenberg of Practical Concepts Incorporated for USAID in 1969 and elaborated by agencies such as GTZ, NORAD, and the European Commission, it forces planners to make explicit the causal logic by which activities are expected to produce outputs, outcomes, and ultimately a development goal.	Participatory Impact Assessment (PIA) is an approach to measuring the impact of development and humanitarian projects in which the affected communities define the indicators of change and use participatory tools to quantify it. Developed and codified by Andy Catley and colleagues at Tufts University's Feinstein International Center, largely through work on livestock and livelihoods programmes in pastoralist settings, PIA adapts participatory rural appraisal methods to the disciplined logic of impact evaluation — combining locally meaningful indicators with before-and-after and with-and-without comparisons to assess what a project actually changed.
