Systems

"The concept of a system is not a simple or unique one. There are many different kinds of systems, and different systems may be organized and operated in different ways. As individuals we all belong to some social system, we participate in an economic system, we are the product of several educational systems, and we are members of one or more family systems. In a similar fashion, the equipment of which physical systems are made may be members of many other systems, such as electrical, mechanical, sensing, actuating, energy, materials, and/or information systems. One of the challenges to the person who engineers a system is to find the many alternative ways in which the function, the operation, and/or the equipment of concern and interest may be considered, understood, and made to perform most effectively."

"A system can be defined as a set of elements standing in interrelations."

"It is sheer nonsense to expect that any human being has yet been able to attain such insight into the problems of society that he can really identify the central problems and determine how they should be solved. The systems in which we live are far too complicated as yet for our intellectual powers and technology to understand."

"'System' is the concept that refers both to a complex of interdependencies between parts, components, and processes, that involves discernible regularities of relationships, and to a similar type of interdependency between such a complex and its surrounding environment."

"The old art depicted space as uniform and enclosed. The new art perceives space as organic and open. The old art was an object. The new art is a system. The configuration of the movement is more important than the shape of the object. The message of a kinetic and luminic work is the light and movement it produces. It has no other message. It has no meaning besides movement."

"A system is anything that is not chaos, and even though history seems highly chaotic at times, we have an intuitive feeling that it is not pure chaos."

"The notion of "system" has gained central importance in contemporary science, society and life. In many fields of endeavor, the necessity of a "systems approach" or "systems thinking" is emphasized, new professions called "systems engineering," "systems analysis" and the like have come into being, and there can be little doubt that this this concept marks a genuine, necessary, and consequential development in science and world-view."

"Everyone knows what engineering is. All that's left is to define systems, and I'm not fool enough to do that."

"is the ordered arrangement of knowledge acquired from the study of systems in the observable world, together with the application of this knowledge to the design of man-made systems."

"As any poet knows, a system is a way of looking at the world."

"Seen politically, systems follow one another, each consuming the previous one. They live on ever-bequeathed and ever-disappointed hope, which never entirely fades. Its spark is all that survives, as it eats its way along the blasting fuse. For this spark, history is merely an occasion, never a goal."

"A system is a set of two or more elements that satisfies the following three conditions. (1) The behavior of each element has an effect on the behavior of the whole. (2) The behavior of the elements and their effects on the whole are interdependent. the way each element behaves and the way it affects the whole depends on how at least one other element behaves. (3) However subgroups of the elements are formed, each has an effect on the behavior of the whole and none has an independent effect on it."

"The principal horror of any system which defines the good in terms of profit rather than in terms of human need, or which defines human need to the exclusion of the psychic and emotional components of that need — the principal horror of such a system is that it robs our work of its erotic value, its erotic power and life appeal and fulfillment. Such a system reduces work to a travesty of necessities, a duty by which we earn bread or oblivion for ourselves and those we love. But this is tantamount to blinding a painter and then telling her to improve her work, and to enjoy the act of painting. It is not only next to impossible, it is also profoundly cruel."

"A system is recognized as such by remaining recognizable as 'itself' in spite of changes in its detailed appearance."

"With increasing size and complexity of the implementations of information systems, it is necessary to use some logical construct (or architecture) for defining and controlling the interfaces and the integration of all of the components of the system."

"For a long time, people have been trying to characterize or define the notion of system. After all, “systems” are supposed to be what System Theory is about. The results so far have been contradictory and unsatisfactory. This confusion at the foundations has led many to conclude that there is no such thing as a "system" and hence to deny that System Theory is about anything. Even those most sympathetic to the notion have difficulties at this level. The very founders of System Theory did not try to say what a system was; and as for System Theory, they characterized it only obliquely, by saying it comprised all studies of interest to more than one discipline. They thereby begged the entire question."

"Enterprise Engineering is based on the belief that an enterprise, as any other complex system can be designed or improved in an orderly fashion thus giving a better overall result than ad hoc organisation and design."

"Today the network of relationships linking the human race to itself and to the rest of the biosphere is so complex that all aspects affect all others to an extraordinary degree. Someone should be studying the whole system, however crudely that has to be done, because no gluing together of partial studies of a complex nonlinear system can give a good idea of the behaviour of the whole."

"What is a system? A system is a network of interdependent components that work together to try to accomplish the aim of the system. A system must have an aim. Without an aim, there is no system. The aim of the system must be clear to everyone in the system. The aim must include plans for the future. The aim is a value judgment. (We are of course talking here about a man-made system.)"

"Another system is possible. Another system is a necessity."

"The term "system" is unquestionably one of the most widely used terms not only in science, but in other areas of human endeavor as well. It is a highly overworked term, which enjoys different meanings under different circumstances and for different people. However, when separated from its specific connotations and uses, the term "system" is almost never explicitly defined."

"In the most abstract sense, a system is a set of objects together with relationships among the objects. Such a definition implies that a system has properties, functions, and dynamics distinct from its constituent objects and relationships."
