Assumptions in problem setting (Schön, 1995)

24 October 2010

When practitioners are unaware of their frames for roles or problems, they do not experience the need to choose among them. They do not attend to the ways in which they construct the reality in which they function; for them, it is simply the given reality. Thus, for example, a planner may take for granted that the housing problem is one of preserving and increasing the stock of decent housing; what else could it be? A development economist may assume without question that the problem in a developing country is that of increasing the rate of industrialization, the growth of gross national product, and the pool of foreign currency available for exchange.

When a practitioner becomes aware of his frames, he also becomes aware of the possibility of alternative ways of framing the reality of his practice. He takes note of the values and norms to which he has given priority, and those he has given less importance, or left out of account altogether. Frame awareness tends to entrain awareness of dilemmas.

When a professional community embodies multiple and conflicting ideas in good currency about the frames appropriate to the construction of problems and roles, then practitioners, educators, and students of the profession confront such dilemmas. One cannot be a member of the community without taking account of them. In the field of psychotherapy, as I have noted earlier, practitioners have to deal with a bewildering variety of “schools.” Leston Havens has proposed that these can be grouped into the broad categories of objective-descriptive, interpersonal, psychoanalytic and existential psychiatry. Architects face a similar predicament. They may choose, for example, to be “historicists,” focussing on the development of variations on historical precedents. They may identify with the “modern movement,” which has sought to free itself from historical precedent but has now become something of a tradition in its own right. They may concentrate on building as a craft which utilizes and gives prominence to the unique properties of materials. They may see building as an industrial process which calls for new technologies and for building-systems. Or they may give primary importance to the idea of architecture as a social process in which the users of buildings should participate in design.

Social workers may approach their tasks as clinical caseworkers, monitors and controllers of social behavior, deliverers of social services, advocates of the rights of their clients, or as community organizers. Indeed, in the heady days of the 1960s, some social workers moved sequentially through all of these ways of framing practice roles. Planners, as I have mentioned, construct variations on the roles of policy analysis, design, advocacy, regulation, management, or mediation. In a science-based profession like medicine, a practitioner may see himself as a clinician devoted to the diagnosis and treatment of the diseases of individual patients, as a practitioner of preventive medicine concerned with the larger life situations of whole communities, or as an advocate for the rights and needs of groups of people deprived of decent medical care.

Frame analysis may help practitioners to become aware of their tacit frames and thereby lead them to experience the dilemmas inherent in professional pluralism. Once practitioners notice that they actively construct the reality of their practice and become aware of the variety of frames available to them, they begin to see the need to reflect-in-action on their previously tacit frames …

Traditionally, the discussion of alternative frames, values, and approaches to practice tends to appear in professional communities in the mode of debate among representatives of the contending schools of thought. There is a great deal of polemical writing, in this vein, in the literatures of such fields as architecture, psychiatry, planning, social work, and divinity. There is also a literature of debate in such fields as law, engineering, and medicine between practitioners of the establishment and their radical critics. In this sort of writing, the style of communication is primarily ideological. The protagonists of the various points of view do not reflect on their frames but act from them, seeking to defend their own positions and attack the positions of their opponents. The readers of these literatures may be helped to become aware of alternative points of view, but they are not much helped to reflect on the different frames that underlie them.

Problem setting (Schön, 1995)

24 October 2010

Increasingly we have become aware of the importance to actual practice of phenomena – complexity, uncertainty, instability, uniqueness, and value-conflict – which do not fit the model of Technical Rationality. Now, in the light of the Positivist origins of Technical Rationality, we can more readily see why these phenomena are so troublesome.

From the perspective of Technical Rationality, professional practice is a process of problem solving. Problems of choice or decision are solved through the selection, from available means, of the one best suited to established ends. But with this emphasis on problem solving, we ignore problem setting, the process by which we define the decision to be made, the ends to be achieved, the means which may be chosen. In real-world practice, problems do not present themselves to the practitioner as givens. They must be constructed from the materials of problematic situations which are puzzling, troubling, and uncertain. In order to convert a problematic situation to a problem, a practitioner must do a certain kind of work. He must make sense of an uncertain situation that initially makes no sense.

When professionals consider what road to build, for example, they deal usually with a complex and ill-defined situation in which geographic, topological, financial, economic, and political issues are all mixed up together. Once they have somehow decided what road to build and go on to consider how best to build it, they may have a problem they can solve by the application of available techniques; but when the road they have built leads unexpectedly to the destruction of a neighborhood, they may find themselves again in a situation of uncertainty.

It is this sort of situation that professionals are coming increasingly to see as central to their practice. They are coming to recognize that although problem setting is a necessary condition for technical problem solving, it is not itself a technical problem. When we set the problem, we select what we will treat as the “things” of the situation, we set the boundaries of our attention to it, and we impose upon it a coherence which allows us to say what is wrong and in what directions the situation needs to be changed. Problem setting is a process in which, interactively, we frame the things to which we will attend and frame the context in which we will attend to them.

Even when a problem has been constructed, it may escape the categories of applied science because it presents itself as unique or unstable. In order to solve a problem by the application of existing theory or technique, a practitioner must be able to map those categories onto features of the practice situation. When a nutritionist finds a diet deficient in lysine, for example, dietary supplements known to contain lysine can be recommended. A physician who recognizes a case of measles can map it onto a system of techniques for diagnosis, treatment, and prognosis. But a unique case falls outside the categories of applied theory; an unstable situation slips out from under them. A physician cannot apply standard techniques to a case that is not in the books. And a nutritionist attempting a planned nutritional intervention in a rural Central American community may discover that the intervention fails because the situation has become something other than the one planned for.

Technical Rationality depends on agreement about ends. When ends are fixed and clear, then the decision to act can present itself as an instrumental problem. But when ends are confused and conflicting, there is as yet no “problem” to solve. A conflict of ends cannot be resolved by the use of techniques derived from applied research. It is rather through the nontechnical process of framing the problematic situation that we may organize and clarify both the ends to be achieved and the possible means of achieving them.

Similarly, when there are conflicting paradigms of professional practice, such as we find in the pluralism of psychiatry, social work, or town planning, there is no clearly established context for the use of technique. There is contention over multiple ways of framing the practice role, each of which entrains a distinctive approach to problem setting and solving. And when practitioners do resolve conflicting role frames, it is through a kind of inquiry which falls outside the model of Technical Rationality. Again, it is the work of naming· and framing that creates the conditions necessary to the exercise of technical expertise.

We can readily understand, therefore, not only why uncertainty, uniqueness, instability, and value conflict are so troublesome to the Positivist epistemology of practice, but also why practitioners bound by this epistemology find themselves caught in a dilemma. Their definition of rigorous professional knowledge excludes phenomena they have learned to see as central to their practice. And artistic ways of coping with these phenomena do not qualify for them as rigorous professional knowledge.

This dilemma of “rigor or relevance” arises more acutely in some areas of practice than in others. In the varied topography of professional practice, there is a high, hard ground where practitioners can make effective use of research-based theory and technique, and there is a swampy lowland where situations are confusing “messes” incapable of technical solution. The difficulty is that the problems of the high ground, however great their technical interest, are often relatively unimportant to clients or to the larger society, while in the swamp are the problems of greatest human concern. […]

There are those who choose the swampy lowlands. They deliberately involve themselves in messy but crucially important problems and, when asked to describe their methods of inquiry, they speak of experience, trial and error, intuition, and muddling through.

Other professionals opt for the high ground. Hungry for technical rigor, devoted to an image of solid professional competence, or fearful of entering a world in which they feel they do not know what they are doing, they choose to confine themselves to a narrowly technical practice.
