So which tool to apply - Is the system simple, complicated or complex?
There are so many tools and approaches that it can sometimes be difficult to see the bigger picture that guides the selection of different approaches, and how they interlink in practice. In particular there is a need to appreciate the concepts of complicated and complex in order to fully understand the context and landscape which leads to the choice of appropriate interventions that will address the issues of sustainability.
According to Glouberman and Zimmerman systems can be understood as being simple, complicated, complex. Simple problems, such as following a recipe or protocol, may encompass some basic issues of technique and terminology, but once these are mastered, following the "recipe" carries with it a very high assurance of success. Complicated problems, like sending a rocket to the moon, are different. Their complicated nature is often related not only to the scale of a problem (cf. simple systems), but also to issues of coordination or specialised expertise. However, rockets are similar to each other and because of this following one success there can be a relatively high degree of certainty of outcome repetition. In contrast complex systems are based on relationships, and their properties of self-organisation, interconnectedness and evolution. Research into complex systems demonstrates that they cannot be understood solely by simple or complicated approaches to evidence, policy, planning and management. They require an understanding of unique local conditions and their historical pathways. As a result there is always some uncertainty of outcome.
These reviewers and others on this page remind us that social systems are complex, and aim to help us think about how to carry out useful interventions within complex systems. In this context we can better appreciate that while adaptive, self-organising social networks produce observable patterns in response to interventions that are neither predictable nor generalisable, it remains crucial that we learn to better understand our interventions to inform future possibilities.
Working with complex systems
- Complicated and Complex Systems: What Would Successful Reform
of Medicare Look Like?
Authors Sholom Glouberman and Brenda Zimmerman report that it makes a difference if a problem is viewed as "complicated" or "complex" when applying remedies. In this paper they argue that health care systems are complex, and that repairing them is a complex problem. Most attempts to intervene in Medicare (and in many other health care systems) treat health systems as if they were merely complicated. The paper demonstrates this failure of understanding by tracing the deterioration of Medicare through a series of complicated interventions to its present destabilized state.. The paper suggests that many of these dilemmas can be dissolved if the system is viewed as complex.The paper concludes with the application of a complex systems approach to some of the Canadian problems and identifies what successful reform would look like. Most critically, complicated questions would be transformed into complex ones. For example the complicated question “What are the structures we need to make the health care system sustainable?” becomes the complex question “How do we build on current structures and relationships to stabilize and enhance Medicare?” - Key behaviour change findings and policy implications - diagrammatic overview
In July 2005, the UK-based Defra initiated a programme of research that aimed to broaden understanding of how Government (and others) can most effectively promote pro-environmental behaviour amongst producers and consumers. Defra researchers have begun to synthesise the key recurring messages from this research programme and have incorporated them into a one-page poster - for best effects adjust your printer settings to A3. This page provides a good overview of how to make policy to address complex social systems. More on the results of the wider programme can be accessed at Behaviour Change Research and Guidance. - Weathercocks and signposts: the environment movement at a crossroads This WWF report critically reassesses current approaches based on analogy with product marketing campaigns - particularly when the 'sovereignty' of consumer choice, and the perceived need to preserve current lifestyles intact, are taken as givens. The report constructs a case for a radically different approach. It presents evidence that any adequate strategy for tackling environmental challenges will demand engagement with the values that underlie the decisions we make - and, indeed, with our sense of who we are. Anything else, it argues, may ultimately be a waste of time and money.
- Using participatory and learning-based approaches for environmental management to help achieve constructive behaviour change This report from Will Allen, Margaret Kilvington, and Chrys Horn looks at how agencies can influence people's behaviour to improve environmental management. It highlights new approaches that work with multi-stakeholder groups and teams, in particular those which improve motivation, information flows, and collaborative learning. The report covers four main areas: i) a review of contemporary approaches to environmental policy making; ii) a review of frameworks for supporting behaviour change; iii) providing an outline of the key concepts for managing participation in practice; and iv) a description of techniques for building group capacity for environmental change.
- Recommendations for behaviour change programs to reduce greenhouse impacts in SA
This report by Julia Winefield considers how to achieve a shift towards more sustainable and greenhouse friendly behaviour and make recommendations for behaviour change programs in South Australia based on these findings. It does this by an examination of evidence-based theories of behaviour change and actual programs that have been run in Australia and Canada. - Theories and models of behaviour change
This review by the Victorian TravelSmart program (Australia) explores and considers some of the major theories of behaviour and behaviour change that may be pertinent to the development of effective
interventions in travel behaviour, including theories and concepts from mainstream
psychology, and the associated sub-disciplines of health, leisure, recreation, physical
activity and exercise psychology. - Nine Emerging and Connected Organizational and Leadership Principles "Theory is fine. But what am I supposed to do?" Good question. That's where this article by Brenda Zimmerman, Curt Lindberg, and Paul Plsek comes in. Here you will find summaries of nine specific, action-oriented heuistics (or rules of thumb) for leading in a complex environment. Each principle is accompanied by insights from some of the leading thinkers in complexity science.
- The new dynamics of strategy: Sense-making in a complex and complicated world
This 2003 paper, by Dave Snowden and C. F. Kurtz, challenges the universality of
three basic assumptions prevalent in organizational decision support and strategy:
assumptions of order, of rational choice, and of intent. They categorise activities on four levels of knowledge and organisation--described as the known, the knowable, the complex and the chaotic. The authors go on to describe a framework they have developed to help people make sense of the complexities made visible by the relaxation of these assumptions.
Managing transitions
- Triggering widespread adoption of sustainable behaviour Brook Lyndhurst explored patterns of change relevant to environmental behaviour, in both consumer and business markets. The aim of this project is to illustrate the range and subtlety of possible interventions that might nudge a system towards S-curve development paths. The authros posit that the complexities of behaviour change tends to favour a model of ceaseless innovation within a network setting, rather than a single policy intervention. This may offer a valuable conceptualisation of how to move forward.
- Transition management is a fairly new term being used to describe change-based approaches that are able to take into account a very long time horizon, a multitude of actors with different perspectives, different levels of scale and uncertain future development. Learning is a key focus of such approaches, and transition management can be thought of as a change framework for all levels - from individual to societal. At a governance level see Transition management and Transitions and transition management. At an organizational level see Principles of transition management and Transition management. And at a more individual level see the Transitions framework article about supporting youth in foster care through the same principles. Also Transition Management: Governance for Sustainability.
