Rich Picture is part of the Soft Systems Methodology.
Rich pictures provide a mechanism for learning about complex or ill-defined problems by drawing detailed ("rich") representations of them. Typically, rich pictures follow no commonly agreed syntax, usually consist of symbols, cartoons, sketches or doodles and can contain as much (pictorial) information as is deemed necessary. The finished picture may be of value to other stakeholders of the problem being described since it is likely to capture many different facets of the situation, but the real value of this technique is the way it forces the creator to think more deeply about the problem and understand it well enough to express it pictorially (a process known as action learning).
