"This paper applies systems management and man-environment approaches to redefine urban planning and design as the management of ecological, physiological and psychological health. It addresses consistency and variability in human needs, motivations, preference and emotional response. It develops planning and design approaches, theories and models responsive to variable needs and perceptions. This paper presents a process for determining strategies for urbanization and affordable housing delivery. It addresses global apartheid, and unique opportunities for metamorphosis in the emerging South Africa, as it implements paradigmatic cultural change through evolving equilibrium structures. It applies metamodeling and metabolic planning and design theories, to address rapid urbanization and community-building, discover implementation roadblocks and gaps, and identify "change triggers". It presents consensus-building, conflict-resolution delivery models designed for South Africa's decision-making environments, developed from a systems management and community-participation approach. These models include an Universal Innovation-Intervention Delivery Model; evolutions to deliver appropriate decision-making environments, delivery structures and development patterns: and evolutions for retrofitting urban subcomponents. This paper benefits from case-study testing of one subcomponent model, the Formal-Informal Community Interface Model, to determine implementability in the emerging South Africa; and to identify implementation roadblocks, and potential "change triggers". It addresses applicability of models to other rapidly changing first- and third-world countries."
