The RSVP cycles are defined as resource, score, valuation and performance. Halprin demonstrates in his writings and drawings how these factors relate to the creative processes in a continuous cycle of interrelated activities, and specifically influence urban and environmental planning. He describes scores as "Symbolizations of processes that extend over time...in all fields of human endeavor... as a way of communicating over time and space to other people in other places."The author has written a book based upon futurist theory of connecting avant garde artistic activities with landscape and city planning architecture. -- Source of annotation: Marvin or Ruth Sackner.
