Summary	Matrix scoring and ranking is a participatory rural appraisal tool in which community members evaluate a set of options — crop varieties, services, trees, livestock breeds, sources of water — against criteria they themselves generate, arranged as a matrix. Options run along one axis and criteria along the other, and participants score each cell, typically by placing a number of counters such as seeds or stones to show how well an option performs on that criterion. Summing the scores across criteria produces a ranking of the options that reflects the community's own values and priorities.	An institutional Venn diagram, often called a chapati or relationship diagram, is a participatory rural appraisal tool in which community members represent the organizations and institutions in their lives as circles and arrange them to show importance and relationships. The size of each circle reflects how important or influential the institution is, and its position — how far from the community and how much it overlaps with other circles — shows how close and how connected it is. The finished diagram is a community-drawn map of its institutional landscape and the social distance between people and the bodies that affect them.
