systems

"... what you can be sure of is that many organisms have declined to the point where they can never do the services for us we want — even if the service is the pleasure of seeing a rare bird."

"Humanity depends on healthy ecosystems: they support or improve our quality of life, and without them, the Earth would be uninhabitable. However, over the past 50 years, fast-growing demands for food, , water and other s have led to an unprecedented degradation of many ecosystem services so that their ability to sustain future generations can no longer be taken for granted. Therefore, reversing ecosystem degradation is one of the great challenges of sustainable development. This is by no means a trivial task as it requires action by all actors in society, including governments, industry and individuals. One of the difficulties is that, even if there was a universal commitment to sustainable development, it is still unclear what goods, services and activities are sustainable and how they could be identified."

"Nature underpins human well-being in critical ways, especially in health. Nature provides of nutritious crops, purification of drinking water, protection from floods, and climate security, among other well-studied health benefits. A crucial, yet challenging, research frontier is clarifying how nature promotes physical activity for its many mental and physical health benefits, particularly in densely populated cities with scarce and dwindling access to nature."

"I dare you to stand in a redwood grove and not be humbled, or to dive on a coral reef and see even just the glimmer of its former magnificence and have some respect for these ecosystems and the fact that we are sharing this planet."

"Planet Earth was separated into several ecosystems, each made up of a unique assembly of animals and plants. Homo sapiens was about to put an end to this biological exuberance."

"The organization of life extends beyond the individual organism to the biosphere, the zone of air, land, and water at the surface of the Earth where organisms exist. Individual organisms belong to a population, which is all the members of a species within a particular area. The populations of a community interact among themselves and with the physical environment (e.g., soil, atmosphere, and chemicals), thereby forming an ecosystem."

"If we recognise that every ecosystem can also be viewed as a food web, we can think of it as a circular, interlacing nexus of plant animal relationships (rather than a stratified pyramid with man at the apex)... Each species, be it a form of bacteria or deer, is knitted together in a network of interdependence, however indirect the links may be."

"Ecosystems are characterized by chemical cycling and energy flow, both of which begin when photosynthetic plants, aquatic algae, and some bacteria take in solar energy and inorganic nutrients to produce food in the form of organic nutrients."

"Critical systems thinkers like Midgley identify three waves of systems thinking over the last 50 years or so. Early systems theorists (e.g. Bertalanffy) described systems in physical terms, resorting to metaphors from electronic computation or biology. This 'hard systems' tradition still has its advocates and practitioners... Subsequently the limits of the physical metaphor... were reached, and the second wave of systems thinking developed. This 'soft systems thinking' employed social metaphors to develop appropriate systems approaches for human systems. The move to a more phenomenological, interpretative understanding of human systems, where meaning is central and is negotiated intersubjectively, parallels the new paradigm / crisis of social psychology of the 1970s. The Third wave, or critical systems school, in which Midgley locates himself, has drawn on the critical theory of Habermas, particularly in relation to theories of knowledge and of communicative rationality, and on the work of Foucault and followers on the nature of power."

"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."

"Systems thinking is not new; it has been around for thousands of years in many different guises. Ancient creation myths were instances of systems thinking. Operations analysis, systems analysis, failure analysis, risk analysis, corporate benefit analysis, financial modeling, quantity surveying, investment appraisal, finite element analysis, civil engineering models, economic modeling, simulations, and many more are all modern ways of thinking about systems. Imaginative visualization should be on the list, too. What is new, perhaps, is the ready availability of powerful desktop tools that permit and enable us to think about the most complex and complicated issues and systems. Processors allow us to tackle problems of such complexity and magnitude that, without them, we would be obliged to guess. The same tools reveal unexpected complex behavior from simple systems."

"As our world continues to change rapidly and become more complex, systems thinking will help us manage, adapt, and see the wide range of choices we have before us. It is a way of thinking that gives us the freedom to identify root causes of problems and see new opportunities."

"It was appropriate to say up front that systems thinking is the parent of design thinking and systems inquiry embeds design inquiry."

"The modern systems view, which flowered during World War II (though building on principles in the wind much earlier), has already borne its first fruits and is in danger of a superficial acceptance into the corpus of sociology by way of the incorporation of some of its now common vocabulary."

"Critical systems thinking is a robust recent trend in humanistically oriented systems work. Spearheaded by work of Ulrich (1983), Flood (1990), and Flood and Jackson (1991), this approach manages to accommodate the knowledge-constitutive interests of Jürgen Habermas (1971) and the interpretive analytical orientations of Michel Foucault (1972) through a meta-methodology involving constant critical reflection. The meta-methodology serves as the basis for the generation of a new methodology that critically applies various systems approaches to problem solving."

"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."

"Practitioners and proponents embrace a holistic vision. They focus on the interconnections among subsystems and components, taking special note of the interfaces among various parts. What is significant is that system builders include heterogeneous components, such as mechanical, electrical, and organizational parts, in a single system. Organizational parts might be managerial structures, such as a military command, or political entities, such as a government bureau. Organizational components not only interact with technical ones but often reflect their characteristics. For instance, a management organization for presiding over the development of an intercontinental missile system might be divided into divisions that mirror the parts of the missile being designed."

"Systems Thinking is based on 50+ years of scientific research by the Society for General Systems Research on the 12 Characteristics of life on earth, leading to the natural way the world works."

"The assumptions which underpin hard systems thinking and distinguish it from soft systems thinking can now be clearly recognized. A basic assumption is that the world can be understood objectively and that knowledge about the world can be validated by empirical means. This assumption supports the role of models in the hard tradition, which are seen to be representations of and which can be treated as proxies for the world. Methodologies based in hard systems thinking will reflect this assumption by placing great emphasis upon the modeling and validation processes, for these are central to the ability of the approaches to reproduce behavior in the models they involve A second assumption of hard systems thinking is the ability to define objectives and then to identify the best way of proceeding in order to achieve them. The notions of goal seeking and rational decision making depend upon this assumption, for if objectives cannot be defined, then a process which sets out to find the best way of achieving them is of no value..."

"Systems thinking is a special form of holistic thinking - dealing with wholes rather than parts. One way of thinking about this is in terms of a hierarchy of levels of biological organization and of the different 'emergent' properties that are evident in say, the whole plant (e.g. wilting) that are not evident at the level of the cell (loss of turgor). It is also possible to bring different perspectives to bear on these different levels of organization. Holistic thinking starts by looking at the nature and behaviour of the whole system that those participating have agreed to be worthy of study. This involves: (i) taking multiple partial views of 'reality'... (ii) placing conceptual boundaries around the whole, or system of interest and (iii) devising ways of representing systems of interest."

"Hard systems thinking is also accused of conservatism. It privileges the values and interests of its clients and customers, and lends its apparent expertise to their realization. It thus gives the facade of objectivity to changes that help to secure the status quo. In general terms, despite its many strengths and achievements, hard systems thinking is today thought of as having a limited domain of application."

"If Critical Systems Thinking is to contribute to enlightened societal practice, e.g., with respect to the pressing environmental and social issues of our time, it should be accessible not only to well-trained decision makers and academics but also to a majority of citizens."

"In the selection of papers for this volume, two problems have arisen, namely what constitutes systems thinking and what systems thinking is relevant to the thinking required for organizational management. The first problem is obviously critical. Unless there were a meaningful answer there would be no sense in producing a volume of readings in systems thinking in any subject. A great many writers have manifestly believed that there is a way of considering phenomena which is sufficiently different from the well-established modes of scientific analysis to deserve the particular title of systems thinking."

"In a previous paper on progress in general systems research... I avoided the issue of defining a system. I noted that no definitions are satisfactory, and it seemed to me the essence of the subject area that none can be so. I went on to say that it is the systems approach—emphasizing lack of disciplinary boundaries, the freedom to apply knowledge, and techniques gathered in one field to problems in another, or to suggest that two distinct fields are in fact one, the disciplined freedom of the unconstrained intellect—that has been the source of dynamism and progress. I noted that perhaps the most telling progress of all is that we can so confidently speak of a common field of interest knowing that we could not, and would not wish to, agree on a definition of what a system is."

"Peter Senge (1990), Fritjof Capra (1996), Peter Checkland (1999), and other researchers have transferred systems thinking principles and theories into practice by applying them to real-world organizational- wide issues, thus encouraging the thus encouraging the creation and development of learning organizations."

"Systems thinking is only an epistemology, a particular way of describing the world. It does not tell us what the world is. Hence, strictly speaking, we should never say of something in the world: “It is a system,” only: “It may be described as a system.”"

"Systems thinking, as written about and practiced by Russell Ackoff, C. West Churchman, Peter Checkland and others, contained within it many of the impulses that motivate the application of design ideas to strategy, organization, society, and management. Ideas such as engaging a broad set of stakeholders, moving beyond simple metrics and calculations, considering idealized options and using scenarios to explore them, shifting boundaries to reframe problems, iteration, the liberal use of diagrams and rich pictures, and tirelessly searching for a better set of alternatives were all there. If the business and management community had bought it, we would not be having the many discussions about design, design thinking, and expanding management education to engage the intuitive, to embrace values, to look beyond available choices."

"Systems inquiry has demonstrated its capability in dealing effectively with highly complex and large-scale problem situations. It has orchestrated the efforts of various disciplines within the framework of systems thinking. It has introduced systems approaches and methods to the analysis, design, development, evaluation, and management of systems of all kinds... Systems theory pursues the scientific exploration and understanding of systems that exist in the various realms of experience, in order to arrive at a general theory of systems: an organized expressing of sets of interrelated concepts and principles that apply to all systems."

"Tektology must clarify the modes of organization that are perceived to exist in nature and human activity; then it must generalize and systematize these modes; further it must explain them, that is, propose abstract schemes of their tendencies and laws; finally, based on these schemes, determine the direction of organizational methods and their role in the universal process. This general plan is similar to the plan of any natural science; but the objective of tektology is basically different. Tektology deals with organizational experiences not of this or that specialized field, but of all these fields together. In other words, tektology embraces the subject matter of all the other sciences and of all the human experience giving rise to these sciences, but only from the aspect of method, that is, it is interested only in the modes of organization of this subject matter."

"There is a revolutionary scientific perspective (stemming) from the General Systems Research movement and (with a) wealth of principles, ideas and insights that have already brought higher degree of scientific order and understanding to many areas as of biology, psychology and some physical sciences... Modern systems research can provide the basic of a framework more capable of doing justice to the complexities and dynamic properties of the socio-cultural system."

"Systems thinking means the ability to see the synergy of the whole rather than just the separate elements of a system and to learn to reinforce or change whole system patterns. Many people have been trained to solve problems by breaking a complex system, such as an organization, into discrete parts and working to make each part perform as well as possible. However, the success of each piece does not add up to the success of the whole. to the success of the whole. In fact, sometimes changing one part to make it better actually makes the whole system function less effectively."

"Systems thinking is a mental discipline and framework for seeing patterns and interrelationships. It is important to see organizational systems as a whole because of their complexity. Complexity can overwhelm managers, undermining confidence. When leaders can see the structures that underlie complex situations, they can facilitate improvement. But doing that requires a focus on the big picture."

"A great many writers have manifestly believed that there is a way of considering phenomena which is sufficiently different from the well-established modes of scientific analysis to deserve the particular title of systems thinking."

"An example from soft systems thinking is Checkland's appreciation of soft systems methodology. He wants to introduce hard systems approaches to deal with hard problems only after and through a soft systems analysis."

"An ecological approach to public administration builds, then, quite literally from the ground up; from the elements of a place — soils, climate, location, for example — to the people who live there — their numbers and ages and knowledge, and the ways of physical and social technology by which from the place and in relationships with one another, they get their living. It is within this setting that their instruments and practices of public housekeeping should be studied so that they may better understand what they are doing, and appraise reasonably how they are doing it. Such an approach is of particular interest to us as students seeking to co-operate in our studies; for it invites — indeed is dependent upon — careful observation by many people in different environments of the roots of government functions, civic attitudes, and operating problems."

"Systems thinking is a lost art with a very practical set of tools which our consultants and l use. lt assists us and our clients' thinking, diagnoses, and actions in whatever we do... and wherever we go in a much better, more holistic and practical way than traditional methods."

"Systems thinking is relatively recent, at least as an identifiable practice. There are books on the subject, but different authors view the subject differently, so it is an as-yet unconstrained discipline."

"Complexity by itself is not the catalyst in which a system might crash. Rather, it is how the complexity emerges in a system that determines whether that system will do what it was intended to do or morph into an unworkable organization clogged by bottlenecks and blockages. Does the system emerge through a natural course of events vetted by trial and error, or does it emerge by artificial means that detach the system from its external, self-assembled process?"

"The overall field of systems science is still in formation."

"System theories have been applied to a wide spectrum of empirical cases and policy issues. Parsons and his followers, in particular, applied their systems theory to diverse empirical phenomena in sociology as well as in other disciplines: modernization, economics, politics, social order, industrialization and development, Fascism and McCarthyism, international relations, social change and evolution, complex organizations, health care, universities, religion, professions, small groups, and family as well as abstract questions such as the place of norms in maintaining social order both historically and cross-nationally. Marxian theory and dynamic system theories have also been applied to a spectrum of diverse empirical and policy subjects."

"Systems theory is antireductionist; it asserts that no system can be adequately understood or totally explained once it has been broken down into its component parts"

"# Systems science is that field of scientific inquiry whose objects of study are systems."

"Systems science and technology constitute one aspect of systems thinking, but the humanities and arts make up the other. The fact that design plays such a large part in the systemic treatment of problems makes it apparent that art has a major role in it as well. Ethics and aesthetics are integral aspects of evaluating systems... the systems approach involves the pursuit of truth (science) and its effective use (technology), plenty (economics), the good (ethics and morality), and beauty and fun (aesthetics). To compare systems methodology with that of any of the so-called ‘hard’ disciplines—for example, physics—is to misunderstand the nature of systems. The worry is not that the systems approach is not scientific in the sense which physics or chemistry or biology is, but that some try to make it scientific in that sense. To the extent they succeed, they destroy it."

"What is systems science? This question, which I have been asked on countless occasions, can basically be answered either in terms of activities associated with systems science or in terms of the domain of its inquiry. The most natural answers to the question are, almost inevitably, the following definitions:"

"Within sociology there have been several system theories, differing from one another in the extent to which, for example, human agency, creativity, and entrepreneurship are assumed to play a role in system formation and reformation; conflict and struggle are taken into account; power and stratification are part and parcel of the theory; structural change and transformation – and more generally, historically developments – are taken into account and explained. What the various system theories have in common is a systematic concern with complex and varied interconnections and interdependencies of social life. Complexity has been a central concept for many working in the systems perspective. The tradition is characterized to a great extent by a burning ambition and hope to provide a unifying language and conceptual framework for all the social sciences."

"Systems theory is a science which has the comparative study of systems as its object."

"General systems theory is considered as a formal theory (Mesarovic, Wymore), a methodology (Ashby, Klir), a way of thinking (Bertalanffy, Churchman), a way of looking at the world (Weinberg), a search for an optimal simplification (Ashby, Weinberg), didactic method (Boulding, Klir, Weinberg), metalanguage (Logren), and profession (Klir)."

"Complexity theory is really a movement of the sciences. Standard sciences tend to see the world as mechanistic. That sort of science puts things under a finer and finer microscope. In biology the investigations go from classifying organisms to functions of organisms, then organs themselves, then cells, and then organelles, right down to protein and enzymes, metabolic pathways, and DNA. This is finer and finer reductionist thinking. The movement that started complexity looks in the other direction. It’s asking, how do things assemble themselves? How do patterns emerge from these interacting elements? Complexity is looking at interacting elements and asking how they form patterns and how the patterns unfold. It’s important to point out that the patterns may never be finished. They’re open-ended. In standard science this hit some things that most scientists have a negative reaction to. Science doesn’t like perpetual novelty."

"# Systems science is what systems scientists do when they claim they do science."

"Project management utilises the systems approach to management by having functional personnel (the vertical hierarchy) assigned to a specific project (the horizontal hierarchy)."
