Holism

"Systems engineering as an approach and methodology grew in response to the increase size and complexity of systems and projects... This engineering approach to the management of complexity by modularization was re-deployed in the software engineering discipline in the 1960s and 1970s with a proliferation of structured methodologies that enabled the analysis, design and development of information systems by using techniques for modularized description, design and development of system components. Yourdon and DeMarco's Structured Analysis and Design, SSADM, James Martin's Information Engineering, and Jackson's Structured Design and Programming are examples from this era. They all exploited modularization to enable the parallel development of data, process, functionality and performance components of large software systems. The development of object orientation in the 1990s exploited modularization to develop reusable software. The idea was to develop modules that could be mixed and matched like Lego bricks to deliver to a variety of whole system specifications. The modularization and reusability principles have stood the test of time and are at the heart of modern software development."

"Systems engineering should be, first and foremost, a state of mind and an attitude taken when dealing with complexity."

"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."

"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."

"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."

"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."

"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."

"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."

"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 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."

"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."

"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, 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."

"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 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."

"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."

"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."

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

"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."

"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."

"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."

"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.”"

"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."

"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."

"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."

"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..."

"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."

"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."

"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 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."

"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."

"# The study of relations rather than "entities" with an emphasis on process and transition probabilities as the basis of a flexible structure of many degrees of freedom."

"# A viewpoint that gets at the heart of sociology because it sees the sociocultural system in terms of information and communication nets;"

"# A synthetic approach where piecemeal analysis is not possible due to the intricate interrelationships of parts that cannot be treated out of context of the whole;"

"# A technique for treating large, complex organizations;"

"# A common vocabulary unifying the several "behavioral" disciplines."

"Systems theory provides:"

"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."

"System theory is basically concerned with problems of relationships, of structure, and of interdependence rather than with the constant attributes of objects. In general approach it resembles field theory except that its dynamics deal with temporal as well as spatial patterns. Older formulations of system constructs dealt with the closed systems of the physical sciences, in which relatively self-contained structures could be treated successfully as if they were independent of external forces. But living systems, whether biological organisms or social organizations, are acutely dependent on their external environment and so must be conceived of as open systems"

"A number of proposals have been advanced in recent years for the development of ‘general systems theory’ which, abstracting from properties peculiar to physical, biological, or social systems, would be applicable to all of them. We might well feel that, while the goal is laudable, systems of such diverse kinds could hardly be expected to have any nontrivial properties in common. Metaphor and analogy can be helpful, or they can be misleading. All depends on whether the similarities the metaphor captures are significant or superficial. It may not be entirely vain, however, to search for common properties among diverse kinds of complex systems... The ideas of feedback and information provide a frame of reference for viewing a wide range of situations, just as do the ideas of evolution, of relativism, of axiomatic method, and of operationalism... hierarchic systems have some common properties that are independent of their specific content..."

"[The objective of the Society for General Systems Research]. To encourage the development of theoretical systems which are applicable to more than one of the traditional departments of knowledge. All sciences develop theoretical systems of concepts, relationships, and models. Many of these systems are isomorphic, but their similarity is undetected because of differences in terminology and if other barriers to communications among specialists. Furthermore, systems which have been well worked out can be of assistance in the development of others. The major functions or general systems research are therefore: 1) to investigate the isomorphy of concepts, laws, and models in various fields, and to help in useful transfers from one field to another; 2) to encourage the development of adequate theoretical models in areas which lack them; 3) to eliminate the duplication of theoretical efforts in different fields; 4) to promote the unity of science through improving the communication among specialists."

"General systems theory is a series of related definitions, assumptions, and postulates about all levels of systems from atomic particles through atoms, molecules, crystals, viruses, cells, organs, individuals, small groups, societies, planets, solar systems, and galaxies. General behavior systems theory is a subcategory of such theory, dealing with living systems, extending roughly from viruses through societies. A significant fact about living things is that they are open systems, with important inputs and outputs. Laws which apply to them differ from those applying to relatively closed systems."

"The idea of a systems can be seen as a further generalized and extended thought of the following consideration. First, there is the rather sweeping claim, that "Every system has subsystems". Taking this together with "Every system has its environment", we are indeed confronted with limitless vistas of systems. One us unable to think of anything, or of any combination of things, which could not be regarded as a system. And, of course, a concept that applies to everything is logically empty. What characteristics are there which any object or group of objects could have, such that they would fail to form some kind of system? In my view, general systems theory not only does not, but further could not, answer this question. And it is partly for this reason that I believe that general systems theory is not in fact science at all, but rather naive and speculative philosophy."

"[General System Theory]... is a logico-mathematical field, the subject matter of which is the formulation and derivation of those principles which hold for systems in general."

"General Systems Theory is a name which has come into use to describe a level of theoretical model-building which lies somewhere between the highly generalized constructions of pure mathematics and the specific theories of the specialized disciplines. Mathematics attempts to organize highly general relationships into a coherent system, a system however which does not have any necessary connections with the "real" world around us. It studies all thinkable relationships abstracted from any concrete situation or body of empirical knowledge."

"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?"

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

"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"

"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."
