Thinking about systems thinking Presentation Transcript

  • 1. Thinking About Systems Thinking Dr Mike Yearworth Reader in Systems, Faculty of Engineering 28 th June 2010

    • Kuhn vs Popper – 31 st July 1965
    • Both Kuhn and Popper embody pluralist and universal attitudes to scientific enquiry…
    • “ For Kuhn, a science is always dominated by one paradigm that its members pursue religiously until it runs up against the limits of its puzzle-solving capabilities. Pluralism then emerges in the form of increasingly specialised domains of inquiry, each dominated by its own paradigm…for Popper pluralism is, at least ideally, intrinsic to the day-to-day conduct of scientific inquiry, as scientists are encouraged to proliferate alternative hypotheses that then face stiff cross-examination by standards that command universal assent ….
    • … on the broadest philosophical canvas… Kuhn and Popper represent two radically different ways of specifying the ends of inquiry: What drives our understanding of reality? Where is the truth to be found? Kuhn would have us look to the dominant paradigms, the beliefs and actions of those who have come to be certified as knowers. It is ultimately a backward looking standard, one based on entitlement through survival . For his part, Popper proposed a more forward-looking perspective based on what enables us to think that our knowledge and actions are always subject to improvement.

    • Kuhn vs Popper – 31 st July 1965
    • However, in the absence of standards that command universal assent…
    • “… As science has acquired more secular power, it has tended towards the self-perpetuation of existing regimes, as dominant research programmes are pursued by default, a situation that the sociologist Robert Merton has dignified as the ‘ principle of cumulative advantage ’… all scientists working in the same paradigm are equal, but some are more equal than others. These are the ‘peers’ whose opinion always seems to matter in the ‘peer review process’ used to fund and evaluate scientific research…the acculturation of novices into a scientific paradigm, since thereafter the novice’s mind is set to plough the deep but narrow furrow laid down by her senior colleagues as normal science”

    • Checkland – 1972 to 1999
    • “ Failure ” of Systems Engineering
    • Action Research
    • Weltanschauung
    • The process of enquiry as systemic; learning systems
    • “ Engineers (and Technologists) are impatient with theorizing…little inclined to analyze the way … ”
    • Hierarchy/Emergence and Communication/Control – and ‘ducked’ the reductionism/holism argument
    • Full-blown interpretivist stance

    • Mike Jackson – 1984…
    28th June 2010
    • I think “Systems approaches…” provides us with the theory textbook we need…
  • 10.
    • Mike Jackson – 1984…
    28th June 2010
    • …and “Systems thinking…” is a useful handbook for practice
  • 11.
    • Re-Interpretation of the B&M framework…
    • Jackson and Keys (1984) re-interpreted B&M by
      • re-stating the dimension of social order in B&M, quite usefully, as a dimension of the values/interests of the participants in the system by degree of alignment – from unity, through plural, to conflict. We could also think of this as degree of alignment of stakeholder needs
      • introduced a new dimension which classifies (or defines) complexity as a function of the degree of intentionality, or self-purpose, in the system

    • Thus Jackson’s System of Systems Methodologies (SOSM)….
    Increasing Divergence of Values Interests  Unitary Pluralist Coercive/Conflictual  Increasing Complexity Simple Complex Hard Systems Thinking System Dynamics Org Cybernetics Complexity Theory Soft Systems Approaches Emancipatory Systems Thinking Postmodern Systems Thinking 28th June 2010 Functionalist Interpretivist RS RH
  • 13.
    • Jackson’s classifications of systems thinking into four major Fs; or Paradigms
    • Functionalist
      • systems seem to have a hard, easily identifiable existence independent of us as observers. Understand status quo leading to prediction and control
    • Interpretive
      • system seems ‘softer’ and elude easy identification. Understand such systems by trying understand points of view and intentions of people who create them. Intentionality makes a profound difference, difficult to model, so acquire detailed information by getting involved, “getting inside it” but ultimately objectives are similar to the functionalist
    • Radical Structuralism
      • systems still seem to hard and and external to us as observers, however we can model and we don’t believe that we need to pay much heed to intentionality, however we are interested in conflict and power structures with a view to emancipation from existing structures.
    • Radical Humanism
      • systems are seen as the creative constructs of human beings, to understand them we need to understand their intentions. The way to learn about them is to involve ourselves in their activities and to understand what social arrangements constrain development

    • Critical Systems Practice
    • Functionalist approaches
      • Hard (methodologies: OR, SA, SE; methods: UML, DEs, ABMs, probability, queuing theory…), SD (m&m), org. cybernetics (VSM m&m), complexity theory (method: DEs; methodology:???)
    • Interpretive approaches
      • Methodologies/Methods: Strategic Assumption Surfacing and Testing (SAST), Interactive Planning (IP), SSM, PERIMETA, Group Model Building (SD)
    • Radical Structuralism  Emancipatory approaches
      • Methodologies/Methods: Critical Systems Heuristics (CSH), Team Syntegrity
    • Radical Humanism  Postmodern approaches
      • Methodologies: surely not??? But see Participatory Appraisal of Needs and the development of Action (PANDA) – pragmatic pluralism

    • A last word from Kuhn – 1962
    • Are we experiencing the emergence of a new paradigm?
      • At a philosophical level, no
      • Within engineering, perhaps a very guared yes (e.g. a transformation: civil engineering  engineering for civil society)
    • The answer will of course be decided in the normal Kuhnian way!

    • The motion before us…
    • “ It is believed that terminology employed within the discipline loosely referred to as ‘systems thinking’ is often ambiguous and inconsistent…”
      • Sometimes! And it depends on what you read. If (say) you believe that system dynamics is system thinking (Forrester/Senge/Sterman at MIT) then this is not true.
    • “… and that this is hindering development of systems thinking as a respected academic discipline…”
      • Ambiguity/inconsistency when it does appear is a symptom with more than one root cause. I suggest i) lack of coherent body of knowledge and core journals which allows weak/poor review, ii) existing discipline silos independently discovering/claiming systems thinking, and iii)…
    28th June 2010
  • 17.
    • The motion before us…
    • “… It is felt that this problem stems from a fundamental problem with the philosophical basis of the discipline. ”
      • Not that there is a fundamental problem with the philosophical basis but that there exists disparate paradigms which can all underpin the methodologies that system thinking employs. Personally I am aligned with Jackson in using the B&M framework and taking a critical approach to methodology selection as a way of practising, but accept that I may be biased towards a realist ontology. Perhaps critical realism could provide a basis?

    • But…
    • “ I want to briefly broach the topic of emergence. This is a 1M category of non-identity but is (a) specifically ontological while (b) falling within the generic Hagelianesque class of stratificational dialectics. In emergence, generally, new beings (entities, structures, totalities, concepts,) are generated out of pre-existing material from which they could have been neither induced nor deduced. There is a quantum leap, or nodal line, of (one feels like saying) the materialized imagination – or even, with Hegel, reason – akin to that occurring in the σ or τ transforms of the rudimentary epistemological dialectic of C1.9. This is matter as creative, as autopoietic….”
