TB871: “The Systems Approach is Not a Bad Idea”: the ethical and philosophical legacy of C. West Churchman
Note: this is a post reflecting on one of the modules of my MSc in Systems Thinking in Practice. You can see all of the related posts in this category.
C. West Churchman (1913-2004) was a key figure in the development of systems thinking, particularly during his tenure at the University of California, Berkeley. His work emphasised the necessity of integrating values and ethics into systems approaches, challenging the field to consider the broader consequences of decisions rather than focusing solely on technical solutions.
Values and ethics in Systems Thinking
Churchman’s philosophy rests on the belief that systems design should not be driven solely by efficiency or technical precision. He argued that systems thinking must incorporate ethical considerations, ensuring that the outcomes benefit society at large and do not cause harm. He critiqued approaches that ignored the human and environmental impact of systems, stressing that a purely technical focus could lead to solutions that, while functional, might be ethically questionable. Churchman’s focus on values is explored extensively in Systems Thinkers (pp. 131-139).
The concept of ‘wicked problems’
Churchman is also known for coining the term “wicked problems,” which describes issues that are complex, multifaceted, and resistant to straightforward solutions. These problems are characterised by their lack of clear definitions, their interdependencies, and the difficulty in finding a resolution that satisfies all stakeholders. For Churchman, tackling wicked problems required a deep engagement with the underlying values at play, as well as an understanding that solutions might create new challenges or exacerbate existing ones. (Ramage & Shipp, 2020, p. 134).
“The Systems Approach is not a bad idea”
Churchman’s famous remark, “the systems approach is not a bad idea,” reflects his cautious optimism about the potential of systems thinking. He saw it as a valuable tool for addressing complex issues but was keenly aware of its limitations. In The Systems Approach (1968), he stated, “however a systems problem is solved—by planner, scientist, politician, anti-planner, or whomever—the solution is wrong, even dangerously wrong” (p. 32). This highlights his view that every solution, regardless of how well-intentioned, carries risks and unintended consequences. Churchman believed that while systems thinking could offer valuable insights, it must be applied with an awareness of its inherent limitations and the ethical dilemmas it might create.
Churchman’s emphasis on values and ethics directly influenced the development of Soft Systems Methodology (SSM), particularly in its approach to handling complex, human-centred problems. SSM, pioneered by Peter Checkland, incorporates many of Churchman’s ideas, especially the importance of considering multiple perspectives and the ethical dimensions of systems. SSM’s focus on exploring different viewpoints and understanding the subjective nature of problem situations can be seen as a practical application of Churchman’s broader philosophical concerns. His balanced perspective reminds us that systems thinking is not a panacea and must be applied thoughtfully and critically.
The architect and boundary judgements
In his book The Design of Inquiring Systems, Churchman provides a useful example involving an architect tasked with designing a house. This example illustrates the importance of drawing boundaries and working at different levels of abstraction:
Narrowly, he may think of a particular instance of a design as the specification of a physical house, designated by a complete set of architectural drawings and specifications. In this case, the components may be the rooms, and the relations between the components may be the geometrical scheme of the house in three-dimensional space. But the architect may ask himself a broader question: whether the house is not a component of a larger system, consisting of the family (or its activities) and the house. When he does ask himself this question, he may wonder whether his design task should include the design of a part of the family’s activities. For example, he may wonder whether he can change the family’s typical way of using the kitchen facilities. Still more broadly, he may ask whether the house plus family is not a component of an urban social system, and whether he ought not to consider alternative designs of this entire community. If he perceives his task in the narrowest sense, then he tells himself that the larger system is not his concern; how the family behaves is entirely up to them, or how the community is planned is entirely up to the planners and politicians. In such a case, he believes that the maximum size of the system is the house (plus, say, its location on the land). He may believe that there is a larger system that may concern some other designer; such a larger system may be the city in which the house is to be placed. But as far as he is concerned, larger systems are not relevant to the effectiveness of his choices. (Churchman, 1971)
Churchman used this scenario to highlight how decisions about boundaries shape the final outcome and how important it is to consider these decisions at multiple levels of analysis. This example is a good example of his belief that systems thinking requires careful consideration of the ethical and practical implications of our choices.
Conclusion
Churchman’s legacy in systems thinking is deeply rooted in his commitment to ethics and his recognition of the complexities involved in addressing real-world problems. His contributions continue to influence how we approach and solve difficult issues, reminding us to integrate ethical considerations into our decision-making processes. As we face increasingly complex challenges, Churchman’s ideas about the role of values and the nature of wicked problems offer valuable guidance for anyone engaged in the design and implementation of systems.
