概要	A charrette is an intensive, time-compressed collaborative workshop in which designers, planners, officials, and the public work together over several days to produce a feasible plan or design for a place. Codified by the National Charrette Institute in The Charrette Handbook, the method replaces the slow, adversarial sequence of separate meetings with short, repeated feedback loops in which designs are drawn, shown to stakeholders, critiqued, and immediately revised. Its purpose is to compress months of back-and-forth into a few days and to build shared ownership of the outcome.	Placemaking evaluation is the structured assessment of whether a public-space intervention — a redesigned plaza, a reclaimed street, a new pocket park — actually makes the place more sociable, comfortable, and well used. Drawing on the observational tradition of William H. Whyte and Jan Gehl and codified by the Project for Public Spaces, it combines qualitative place-quality judgements with countable measures of activity, often comparing the same site before and after the change. The result is evidence that a place works for people rather than a designer's assertion that it should.
