ABSTRACT
The first part of this chapter is a review of the evolution of the systems movement and a discussion of human systems inquiry.
Systems inquiry incorporates three interrelated domains of disciplined inquiry: systems theory, systems philosophy, and systems methodology. Bertalanffy (1968) notes that in contrast with the analytical, reductionist, and linear-causal paradigm of classical science, systems philosophy brings forth a reorientation of thought and worldview, manifested by an expansionist, nonlinear dynamic, and synthetic mode of thinking. The scientific exploration of systems theories and the development of systems theories in the various sciences have brought forth a general theory of systems, a set of interrelated concepts and principles, applying to all systems. Systems methodology provides us with a set of models, strategies, methods, and tools that instrumentalize systems theory and philosophy in analysis, design, development, and management of complex systems.
