The effort to get rid of what we do not want is reactive, retrospectively oriented problem solving. The effort to obtain what we want is proactive, p… - Russell L. Ackoff

I began graduate work in the philosophy of sciences at the University of Pennsylvania in 1941 where I came under the influence of the “grand old man” of the department, the eminent philosopher E.A. Singer, Jr. Because of the informality of the department he created I began to collaborate with two younger members of the faculty, both of whom were former students of Singer, Thomas A. Cown and C. West Churchman. Three aspects of Singer's philosophy had a particularly strong influence on me. First, that the practice of philosophy, its application, was necessary for the development of philosophy itself. Second, that effective work on “real” problems required an interdisciplinary approach. Third, that the social area needed more work than any of the other domains of science and that this was the most difficult. We developed a concept of a research group that would enable us to practice philosophy in the social domain by dealing with real problems. The organization we designed was called “The Institute of Experimental Method.” With the participation of a number of other graduate students in philosophy and a few other members of the faculty we started this institute on a completely informal basis.

The systems approach to problems focuses on systems taken as a whole, not on their parts taken separately. Such an approach is concerned with total- system performance even when a change in only one or a few of its parts is contemplated because there are some properties of systems that can only be treated adequately from a holistic point of view. These properties derive from the relationship between parts of systems: how the parts interact and fit together
