Ivan Illich (1973) “Tools for Conviviality”

“Elite professional groups . . . have come to exert a 'radical monopoly' on such basic human activities as health, agriculture, home-building, and learning, …. The result of much economic development is very often not human flourishing but 'modernized poverty,' dependency, and an out-of-control system in which the humans become worn-down mechanical parts. “

Albert Einstein:

“We can't solve

problems by using

the same kind of

thinking we used

when we created

them.”

Page 9: Systems for sustainability workshop
Page 10: Systems for sustainability workshop

The dominant worldview: reductionism

• Things can be understood by reducing them to their constituent components – by studying “the parts”, you will understand “the whole”.

Page 11: Systems for sustainability workshop
Page 12: Systems for sustainability workshop

Reductionist implications:

• detaching emotion from rationality;• detaching humanity from nature;• citizens unable to see the “bigger

picture”;• citizens unable to see the “greater

purpose”;• “learned helplessness”.

What is a “System”?

A system emerges from… “interdependent components which regularly interact and form a unified whole”.

Um sistema consiste em… “componentes interdependentes que interagem regularmente e formam um todo unificado”.

Page 19: Systems for sustainability workshop

Systems have ‘emergent properties’

• “the whole is greater than the sum of its parts”.

Page 20: Systems for sustainability workshop

System structure, processes and purpose

Page 21: Systems for sustainability workshop

What connects/flows across system components?

• Energy;• Matter;• Information.

Page 22: Systems for sustainability workshop

What is the difference between energy, matter and

information?

• Energy and matter are “causal inputs” to systems – they directly affect system processes.

• Information is instead a “sensory input” and is used to predict the occurrence of causal inputs or other sensory inputs (sometimes at a later time or another place).

Page 23: Systems for sustainability workshop

System structure: ‘individualistic’ architecture

Page 24: Systems for sustainability workshop
Page 25: Systems for sustainability workshop

System structure: “egalitarian” networks

Page 26: Systems for sustainability workshop
Page 27: Systems for sustainability workshop

System structure: “hierarchical networks”

Page 28: Systems for sustainability workshop
Page 29: Systems for sustainability workshop

Think of a simple system, and….

•…..map its structure;•….. describe its processes;•….. identify its purpose/emergent properties.

Page 30: Systems for sustainability workshop

Nested systems

Page 31: Systems for sustainability workshop

Simple systems

• Predictable;• Mechanical;

"Reductionism produced a

"machine view" of the world, a

view captured in the work of Sir

Isaac Newton. Metaphorically the

world was likened to a sealed

clock, a closed system,

perpetually running on

fundamental laws like "to

everything action there is an

equal and opposite reaction."

Hutchins, Systemic Thinking,

1995

‘Problems’ are Systems

• ‘Tame’ and ‘Wicked’ problems (Rittel & Webber, 1973);

• ‘Difficulties’ and ‘Messes’ (Ackoff, 1974).

• ‘Simple’, ‘Complicated’ and ‘Complex’ problems (Glouberman & Zimmerman, 2002)

Page 44: Systems for sustainability workshop

Tackling ‘wicked problems’

Roberts (2000 )identifies the following strategies to cope with wicked problems:

• Authoritative;• Competitive;• Collaborative.

Page 46: Systems for sustainability workshop

Who should lead on transforming society towards

sustainability? Enterprise

by developing green technologies and

mobilising consumers

Governments by establishing

strong regulation.

No one!Enterprise is only out to

make money, governments are

corrupt, and communities no longer

exist.

Communitiesby creating local self-sustaining lifestyles.

Page 51: Systems for sustainability workshop

Adaptive cycle

Page 52: Systems for sustainability workshop

Characteristics of systems during different phases of the adaptive cycle

• Renewal phase: new organisational forms; innovation; creativity.

• Growth phase: increasing organisational complexity; diversification.

• Conservation phase: organisational complexity stable; optimisation; specialisation; efficiency; resistance.

• Release phase: breakdown of organisational complexity; survival.

Page 53: Systems for sustainability workshop

‘Hard’ systems approach

• Expert led, quantitative, rational.

• Great for predicting the state of

simple/complicated systems;

• Positivist epistemology;

Page 54: Systems for sustainability workshop
Page 55: Systems for sustainability workshop
Page 56: Systems for sustainability workshop

‘Soft’ systems approach

• Ideal for working through highly complex problems where there is uncertainty and conflict.

• Better for understanding the less tangible elements of problem situations – things like human motivation and interaction.

• Constructivist epistemology.• Qualitative.• Participatory.

Page 57: Systems for sustainability workshop

March (1994) argues that we have:

– problems of memory;

– problems of attention;

– problems of comprehension;

– problems of communication;

Page 58: Systems for sustainability workshop

Problems of memory

Page 59: Systems for sustainability workshop
Page 60: Systems for sustainability workshop

How many can you remember?

Page 81: Systems for sustainability workshop

Are you analytical or intuitive?

If 1 = 5, 2 = 25, 3 = 325, 4 = 4325, 5 = ?

Page 82: Systems for sustainability workshop

Soft systems approaches try to accommodate human

limitations and differences in perspective

Page 83: Systems for sustainability workshop

‘Complexity Thinking’ approach

• Self organising: encouraging a system which will spontaneously emerge as the actions of autonomous participants come to be interlinked and co-dependend on each other.

• Evolutionary: the system will be able to change its structure and processes as it adapts to maintain its viability within a changing, dynamic context. In other words, the system will be designed to learn from its experiences.

Page 84: Systems for sustainability workshop

Complexity thinkers:

Kevin Kelly (1995) Out Of Control – The New Biology of Machines:

“As we shape technology, it shapes us. We are connecting everything to everything, and so our entire culture is migrating to a "network culture" and a new network economics.”

Page 85: Systems for sustainability workshop

Complexity thinkers:

Manuel Castell (2001) The Internet Galaxy - Reflections on the Internet, Business, and Society:

" the Internet is the technological basis for the organizational form of the Information Age: the network."

Systems methodologies and techniques

• ‘Hard’ Systems:– System Dynamics Modelling;– Qualitative System Dynamics (Systems Archetypes); – Viable Systems Model;

• ‘Soft’ Systems:– Soft Systems Methodology;– Critical Systems Heuristics;– Systemic Action Research;– Systemic Grounded Theory and Action.

• ‘Complex’ Systems:– Network Analysis;– Agent-Based Modelling

Page 91: Systems for sustainability workshop

Common characteristics of systems methodologies and

techniques• Start with an unstructured exploration;• Multi- and inter-disciplinary;• Blend expertise and participation;• Blend of written, numerical and visual

information;• All require the construction of a systems

model;• Interventions through identifying points of

leverage within the system of interest;• Emphasis on social learning;• Iterative

Page 92: Systems for sustainability workshop

T863 Environmental Decision-Making Framework

Page 93: Systems for sustainability workshop

Explore the situation• Decide on which rung of the “ladder of

participation” to involve stakeholders (Arnstein, 1969).

Page 94: Systems for sustainability workshop

Explore the situation

• Unstructured, intuitive, visual exploration often using diagramming techniques such as the ‘rich picture’ and/or ‘spray diagrams’;

Page 95: Systems for sustainability workshop
Page 96: Systems for sustainability workshop

Explore the situation

Facilitator(s) and participants need to be explicit about their values, experiences and interests; – What is the nature of your

stakeholding?– What role do you play in the situation?– Are you a beneficiary? Victim?

Page 97: Systems for sustainability workshop

Formulate systems of interest

• Establish system boundary, components, structure and processes.

• Use diagramming techniques such as systems map; influence diagram; multiple cause diagram; and causal loop diagram.

Page 98: Systems for sustainability workshop
Page 99: Systems for sustainability workshop

Identify feasible and desirable changes

• Creative problem solving entails an innovative ability to make connections between wholly unrelated perspectives or ideas.

• Identify points of leverage within the system of interest and at various system scales.

• Change system structures and processes.• Introduce new system(s).• Assess feasibility and negotiate desirable

options.

Page 100: Systems for sustainability workshop
Page 101: Systems for sustainability workshop

Take action• The impact of interventions within

complex systems are rarely predictable.

Page 102: Systems for sustainability workshop

Iteration

• Always collect data/opinions on the impact of actions, including perspective from stakeholders.

• Always start with an unstructured exploration, even if you think you know the system.

• Ideally, bring in new perspectives.• Tendency towards rationalisation –

remember to keep a balance between right and left brain!

Page 103: Systems for sustainability workshop

How would you implement systemic action learning within your classroom?

• Problem-based learning.• Multi-, inter-, trans-disciplinary lessons.• Learning outside of the class in the “real

world”• Practice what you preach: non-

hierarchical, egalitarian structures and processes.

• Promote relational, visual forms of communication.

• Complex systems never produce simple “right” answers.

Page 104: Systems for sustainability workshop

Stafford Beer, 1974, Designing Freedom, pp 60-61

• "Every pupil is a high-variety organism, and the process of education essentially constrains variety. In other words, the pupil is capable of generating many responses to the question: what is six multiplied by seven; the educator will seek to attenuate this potential variety to the single answer: forty-two. But if we take a different kind of example, we may find ourselves saying something significantly different. The pupil is capable of generating many responses to the question: how should a national health service be organised? This time, however, we may hope that the educator will not attenuate potential variety to the singular answer: like this. No, we say; education is a word coming from the Latin: e-ducere, "to lead out". It does not mean "to push in". And yet it remains true that in any case the process of education constrains variety. Anyone who thinks over this little paradox for a few minutes can see that, in the second example, the hope is that we can teach the pupil ways of attenuating his own variety. We want to offer him ways of finding answers, not of enforcing our own."

Activity

• Identify a wicked problem in your community which you can work through with your class.

• Explain why it's a wicked problem• Propose a systemic framework for

how you would tackle the problem• Provide a brief worked example

illustrating how you would apply your framework to the problem.
