C. WEST CHURCHMAN: CHAMPION OF THE SYSTEMS APPROACH



Introduction

C. West Churchman was educated at the University of Pennsylvania in Philosophy, and studied under the world-renown philosopher, E.A. Singer.  Although his contributions are many, as he has written hundreds of articles, books, and proceedings, he is primarily known for being a founder and champion of the “systems approach” (a holistic, scientific approach to systems planning).[1]  To become acquainted with Churchman’s ideas, it is important to briefly address his conceptual evolution, then to broadly introduce the systems approach using three books:  The Systems Approach (1969), Designing Inquiring Systems (1971), and The Systems Approach and Its Enemies (1979).  A wide range of scholars have been influenced by Churchman, including Russell Ackoff, Peter Checkland, and Werner Ulrich, and they will be briefly discussed.


Evolution

Churchman credits Singer with the systems approach.  He describes the goal of his academic journey as an attempt to apply Singer’s “theme of comprehensiveness” to see whether “Singer’s systems approach really worked” (Churchman, 1971, p.10).  Churchman’s intellectual journey took him through statistics, mathematics, experimentation, and beyond.

Churchman eventually concluded that disciplinary politics within the “sciences” led to isolation of the various disciplines.  He felt that to truly apply the systems approach, a cross-disciplinary science was in order.  Churchman appropriated the term operations research from his military experience, and began the first Operations Research Department at the Case Institute of Technology.  Other universities quickly followed [2] and he developed the first text book in operations research with his student and associate Russel Ackoff (Churchman, Ackoff, & Arnoff, 1957).He was initially unsuccessful in looking to apply his cross-disciplinary ideas in city planning, labor unions, government, and other types of organizations where he thought they might be applying a systems approach.  He finally found a home for systems approach research in industry, as he found that “many American managers of industry are quite inquisitive” (Churchman, 1971, p.15).  As an outlet for interdisciplinary management research, Churchman helped found Management Science, and was the journal’s first editor.

A major activity of operations researchers was to apply mathematical models to systems.  Although Churchman advocated the use of such mathematical models, he understood the limitations associated with such applications and wrote about them as early as 1946 in Psychologistics (with R. Ackoff).  In order to operationalize concepts such as knowledge, intelligence, and preferences, the scientist must also take into consideration a given subjects values: “not merely show a man how to better gain his goals.  It also estimates for him what his goals really are – something he may not be aware of at all” (Churchman, 1961, p.207).  Such estimation would call into question the objectivity and impartiality of the scientist.  As he summarized, “Tomorrow’s science will not be objective.  Rather, the dichotomies, objective-subjective, biased-unbiased, will cease to have their present significance… the day of “objectivity” and immunity are over already” (Churchman, 1961, p.209). 

In his work with industry, he prescribed mathematical modeling as part of a systems approach to managerial systems planning such as linear modeling and probability statistics (Churchman, 1969).  However, to the academy, he stressed value-oriented concepts to systems planning.  In one of his earliest papers about management he described the implementation activity as influenced by the dynamic that occurs between distinct personalities of scientists and managers engaging in a systems plan.  He developed four ideal types, separate functionalist, persuader, communicator, and mutual understander, and discusses them from a purely theoretical standpoint.  Only in an appendix does he formalize his theory (Churchman & Schainblatt, 1965).


The Systems Approach

Basics

A system is a “set of parts coordinated to accomplish a set of goals” (Churchman 1968, p.29), which can be rephrased as “structures that have organized components” (Churchman 1971, p. 7).  The systems approach employs models, usually mathematical models, in order to holistically view a system.  A model is a “way in which the human thought process can be amplified” (Churchman 1968, p.61), or “as methods of trying to measure reality, to approximate it” (Churchman 1979, p. 52).  It is important to keep from oversimplification when using models, however, as a model can never capture the full intricacies of a system.  One key limitation of using models is that “the system is always embedded in a larger system,” so although a model may work for a given system’s goals, it may be completely unsuccessful in terms of the larger systems goals (Churchman 1968, p. 75).  Churchman defended a scientist’s use of incomplete models as defining “a philosophy of life…And if my philosophy precedes my precise method in the exploration of whole systems, then, when my technical capability catches up, we shall be so much better prepared to use it” (Churchman 1968, p. 77).  Churchman offers five considerations to keep in mind when thinking about meaning of a system:  (1) total system objectives & performance measures; (2) the system’s environment and fixed constraints; (3) resources of the system; (4) components of the system, their activities goals and measures; (5) management of the system (Churchman 1968, p. 29-30).


The Environmental Fallacy

Churchman positions the systems approach as the answer to the “environmental fallacy” prevalent in organizational planning.  An environmental fallacy occurs when people build up a crisis (unnecessarily focusing on the urgency of the situation), and then apply non-holistic, direct means to solve the problem.  Examples Churchman offers include anti-drug legislation and pollution control measures.  Such action very often exacerbates or adds to the original problem in the effort to eliminate it directly (Churchman 1979).  The systems approach looks to address problems while taking into consideration the consequences of any given action throughout a given system, as well as historical precedent.  According to Churchman, “one of the most flagrant examples of environmental fallacy is the failure to recognize history as part of our environment… we tend to regard every current crisis as essentially a novel one, and show little interest in its historical roots” (Churchman 1979, p.29).


Designing Inquiring Systems

In answer to prevailing scientific thought regarding human subjects, where there is considered (at the time) to be “objectivity” and “quality of results”, Churchman puts forth that “the essence of the systems approach is the design of an inquiring system that is most capable of unfolding the relevant issues concerning the human condition” (Churchman 1979, p.147).  He looked to use the systems approach to answer how it might be possible to design an “inquiring system,” using human scientists as a reference for such a system.  An underlying motive of his for this exercise was to “determine how one might use high-speed computer-processing machinery to perform the acts now commonly performed by the research-scientist” (Churchman, 1971, p.259).

To fully develop this idea, Churchman enlisted five philosophers, Leibniz, Locke, Kant, Hegel, and Singer, to develop a set of archtypical inquiring systems (Churchman, 1971). He takes as a point of departure the what he characterizes as the "pluralist" tradition, a label he uses for the bulk of positivistic, empirisist, and incremental (non-holistic) inquiry.  In the tradition of other rationalists such as DeCartes and Spinoza, a systems approach looks to address the "whole" system, and this necessarily requires that different assumptions and assertions be sorted through by the inquiring system.  He offers a typology as a method for differentiating between the way in which inquiring systems essentially address validity.  A Leibnizian system is comprised of a store of "fact nets," some of which contend with each other, and rational / deductive processes allow the system to test certain fact nets against other.  Lockean inquiring systems, on the other hand, use community agreement to judge between alternative perspectives.  While both the Leibnezian and Lockean enlist a singular device to choose between competing assertions (i.e., deduction and agreement), Kantian inquiring systems appreciate the different guarantors associated with each world-view in the system, and understand that choosing between worldviews involves understanding the assumptions that comprise different world-views. 

For these three systems agreement indicates an end to inquiry, whereas the Hegelian and Singerian inquiring systems see agreement as a starting point for inquiry.  Upon agreement, Hegelian systems look to introduce a "deadly enemy" proposal to a position, in order to challenge that position and learn through the resulting synthesis.  The Hegelian system is one of storytelling - tension is intentionally introduced for the sole purpose of being resolved.  As the story continues, new tensions continue to be introduced.  The Singerian inquiring system takes the spirit of the Hegelian inquirer and adds teeth to it.  Rather than introducing a single "deadly enemy" and expecting synthesis, the "restless" Singerian system understands that fundmental assumptions must be methodically challenged through the introduction of alternative measurements and new system elements are introduced to continually create knowledge.

Churchman's five inquiring systems have been used extensively in academic literature.  For example, in information systems literature, they have been proposed as a basis for the design of information systems in general (Mason & Mitroff 1973), specific domains of information systems such as decision support systems (Courtney 2001), as well as for a particular information system (Boland et al 1994).  The five inquirers have also recently been used to guide thinking on idea generation (Vandenbosch et al 2006). 



Enemies of the Systems Approach

Many fail to use the systems approach because their worldview (often unwittingly) dooms them to the mode of the environmental fallacy.  Others, however, actively oppose the ideals of the systems approach by the nature of ideals that are consistent with the “enemies” of the systems approach – they do not accept the rationality of the “whole system.”  Churchman states that these enemies manifest themselves in the form of politics, religion, morality, and aesthetics, who’s reality “cannot be conceptualized, approximated, or measured,” according to their proponents (Churchman 1979, p.53).  These proponents often include modern academia, largely from the political perspective.  In the following excerpt, Churchman describes the plight of the “hero” of the systems approach, given his enemies within academia:

The story begins with a somewhat disgruntled hero, who perceived of the world as populated with stupid people, everywhere committing the environmental fallacy.  The fallacy was a case not merely of the “mind’s falling into error,” but rather of the mind leading all of us into incredible dangers as it first builds crisis and then attacks crisis.

Like all heroes, this one looked about for resources, for aids that would help in a dangerous battle, and he found plenty of support – in both the past and the present.  It won’t hurt to summarize the story thus far.  If the intellect is to engage in the heroic adventure of securing improvement in the human condition, it cannot rely on “approaches,” like politics and morality, which attempt to tackle problems head-on, within the narrow scope.  Attempts to address problems in such a manner simply lead to other problems, to an amplification of difficulty away from real improvement.  Thus the key to success in the hero’s attempt seems to be comprehensiveness.  Never allow the temptation to be clear, or to use reliable data, or to “come up to the standards of excellence,” divert you from the relevant, even though the relevant may be elusive, weakly supported by data, and requiring loose methods.

Thus the academic world of Western twentieth century society is a fearsome enemy of the systems approach, using as it does a politics to concentrate the scholars’ attention on matters that are scholastically respectable but disreputable from a systems-planning point of view. (Churchman 1979, p.145) 

The hero of the systems approach, described above, has a certain arrogance - a philosopher-king who is able to rationally analyze “whole” systems without falling prey to emotional crises and short-sighted thinking.  Using this device of the hero, Churchman shows how the enemies are woven into the fabric of humanity and its systems.  It is difficult to sweep these enemies into a systems approach - though for a good portion of the book it may appear that such a reconciliation might be Churchman’s aim.  In the end, what we find is that these enemies are fundamental aspects of being human.  Polis is essential to accomplishing anything; morality is inexorably linked to any values that drive questions and conclusions; religion is a driving force even to the non religious; and aesthetics are indescribable yet inseparable from being human. Churchman charges us with continuing to attempt our holism and rationality, yet do so from a reflective perspective, always understanding that not only is the system full of enemies to this rationality, but that we are subject to the influence of these enemies, as well.
 
 

Information Systems

Churchman’s interest in computing reaches extensively beyond the metaphor of inquiring systems.  He addresses many issues with the state of MIS research of his time, including the tendency of IS researchers to focus on “safe” issues such as “structure of files, retrieval techniques, automatic abstracting, and the like” (Churchman 1968, p.111).  He indicates that the majority of such research is not consistent with the systems approach as it focuses on transactions rather than the true goals or benefit of the system.  Churchman is also quite visionary as he predicts the ubiquitous role of computers in everyday life.  With the ability to “find facts” readily, Churchman predicted that information systems will actually work to reinforce a user’s Weltanschauung (world-view), as the user would screen information based on his Weltanschauung.  In order to expand use MIS to expand the user’s view to one that is more holistic, Churchman envisioned a “deadly enemy” proposal for the design of an information system.  The main role of this deadly enemy is for the system to propose information results based on assumptions that are opposite of the user’s information request, thereby revealing to the user his fundamental assumptions and at the same time questioning them (Churchman 1968, p. 122-123).

 

Associated Scholars

Three names who are often associated with Churchman and the systems approach are Russell Ackoff, Peter Checkland, and Werner Ulrich.  Ackoff was Churchman’s first doctoral student, and his close associate for many decades.  Checkland is credited with the “soft systems approach.”  Ulrich extended Churchman’s work to “critical systems thinking.”

Russell Ackoff

Ackoff founded the operations research program at Case along with Churchman, and they have published a number of books and articles together, including Psychologistics (1946), Methods of Inquiry (1950), and Introduction to Operations Research (1957).  Two books considered to be classics that he wrote independently are Scientific Method (1962) and Redesigning the Future (1974).

Peter Checkland

Checkland distinguished between “hard” systems problems that have specific goals and can generally be defined adequately.  “Soft” systems problems, on the other hand, can be vague and have large social and/or political components.  Checkland has developed a process for addressing the latter issues and describes them in his classic books, Systems Thinking, Systems Practice (1981); and Soft Systems Methodology In Action (1990, with Jim Scholes).

Werner Ulrich

Another student of Churchman’s, Ulrich extended the systems approach to better understand the issues associated with determining the boundary of the system and the values associated with the implementation and measurement of practical results.  He presents his ideas as “critical systems heuristics” in his book, Critical Heuristics of Social Planning (1983).

 

Conclusion

Churchman was equally comfortable in the spheres of theoretical philosophy and in-depth formalization of systems, and he believed the two should work together to help the manager engage in systems planning for the best results.  Although Churchman was an advocate of mathematical modeling, he saw it as one of many tools to be applied in context.  He regretted that early Management Science work could only be politically accepted by the board if it were associated with mathematical models, and in his lifetime he regretted that the multi-disciplinary operations research approach he created became entirely absorbed in unapplied mathematical models (Churchman, 1971).

With all of his philosophical framing of issues, theorizing and contextualizing of the mathematical approach, there was no question as to where his heart was as he answered the relativist criticisms in the days of his key contributions:

Some will inevitably think that I have “sold out” to the enemy, that is, to those who claim that ‘none of the above’ is, in fact, all that there is to reality; certainly such a viewpoint is popular among today’s ‘radical’ intellectuals.  But my point is that if you have never explored the intricacies of trying to model reality within a mathematical language, then you, too, have missed the generality of reality.  It is really quite inappropriate to claim that a mathematical model cannot represent reality when you have no idea at all as to what a ‘mathematical model’ is.  (Churchman, 1979, p.xi)

Of course, the skeptic is an arrogant fellow.  The easiest thing in the world is to be a relativist, somebody who says, ‘it all depends’ and ‘we can never know the ultimate answers.’  This is something that every student who has ever dug deeply in a social problem will say.  It is the mark of a sophomore in the intellectual enterprise.  The one thing the skeptic rarely does is to defend his own skepticism.  He simply shows the extreme difficulties in answering questions, and as a consequence he regards the difficulty as evidence of his own skeptical philosophy.  To the serious-minded, this kind of relativism serves little purpose and is socially irresponsible… His approach to systems is that there is no sound approach, and that’s that. (Churchman, 1968, p.217)

Throughout his career, and especially the last twenty years of his life, Churchman focused increasingly on ethics associated with systems.  He consistently believed that the goals of a system were inherently not value-neutral, and that a system was ethically motivated.  The ethics associated with a system develop through continuous debate that “dries up once it is locked in a debate between academics who have rarely seen or touched the vital ethical body of real human beings in their daily lives.” (Churchman 1979, p.118)
