First published in 1977, this volume was intended as a sourcebook for designers and attempts to specify the ingredients necessary to develop a design program rather than postulate a model program for which no consensus exists. As such it filled a void in the existing literature which seldom covered programming with much depth and provides technical aids to guide designers. The author attempts to integrate the pioneering contributions from others in order to identify the substance of programming for designers and represents a culling of the strategies and techniques from the social, behavioural and management sciences -- building on the developing efforts of other disciplines.
