The term "problem structuring methods" as a label for these techniques began to be used in the 1980s in the field of operations research, especially after the publication of the book Rational Analysis for a Problematic World: Problem Structuring Methods for Complexity, Uncertainty and Conflict. Some of the methods that came to be called PSMs had been in use since the 1960s.
Thinkers who later came to be recognized as significant early contributors to the theory and practice of PSMs include:
In discussions of problem structuring methods, it is common to distinguish between two different types of situations that could be considered to be problems. Rittel and Webber's distinction between tame problems and wicked problems (Rittel & Webber 1973) is a well known example of such types. The following table lists similar (but not exactly equivalent) distinctions made by a number of thinkers between two types of "problem" situations, which can be seen as a continuum between a left and right extreme:
Different types of situations, and thinkers who named themPSMs were developed for situations that tend toward the wicked or "soft" side, when methods are needed that assist argumentation about, or that generate mutual understanding of multiple perspectives on, a complex situation. Other problem solving methods are better suited to situations toward the tame or "hard" side where a reliable and optimal solution is needed to a problem that can be clearly and uncontroversially defined.
Problem structuring methods constitute a family of approaches that have differing purposes and techniques, and many of them had been developed independently before people began to notice their family resemblance. Several scholars have noted the common and divergent characteristics among PSMs.
Eden and Ackermann identified four characteristics that problem structuring methods have in common:
Rosenhead provided another list of common characteristics of PSMs, formulated in a more prescriptive style:
An early literature review of problem structuring proposed grouping the texts reviewed into "four streams of thought" that describe some major differences between methods:
Mingers and Rosenhead have noted that there are similarities and differences between PSMs and large group methods such as Future Search, Open Space Technology, and others. PSMs and large group methods both bring people together to talk about, and to share different perspectives on, a situation or state of affairs that some people want to change. However, PSMs always focus on creating a sufficiently rigorous conceptual model or cognitive map of the situation, whereas large group methods do not necessarily emphasize modeling, and PSMs are not necessarily used with large groups of people.
There is significant overlap or shared characteristics between PSMs and some of the techniques used in participatory rural appraisal (PRA). Mingers and Rosenhead pointed out that in situations where people have low literacy, the nonliterate (oral and visual) techniques developed in PRA would be a necessary complement to PSMs, and the approaches to modeling in PSMs could be (and have been) used by practitioners of PRA.
In 2004, Mingers and Rosenhead published a literature review of papers that had been published in scholarly journals and that reported practical applications of PSMs. Their literature survey covered the period up to 1998, which was "relatively early in the development of interest in PSMs", and categorized 51 reported applications under the following application areas: general organizational applications; information systems; technology, resources, planning; health services; and general research. Examples of applications reported included: designing a parliamentary briefing system, modeling the San Francisco Zoo, developing a business strategy and information system strategy, planning livestock management in Nepal, regional planning in South Africa, modeling hospital outpatient services, and eliciting knowledge about pesticides.
Software programs for supporting problem structuring include Banxia Decision Explorer and Group Explorer, which implement cognitive mapping for strategic options development and analysis (SODA), and Compendium, which implements IBIS for dialogue mapping and related methods; a similar program is called Wisdom. Such software can serve a variety of functions, such as simple technical assistance to the group facilitator during a single event, or more long-term online group decision support systems.
Some practitioners prefer not to use computers during group work sessions because of the effect they have on group dynamics, but such use of computers is standard in some PSMs such as SODA and dialogue mapping, in which computer display of models or maps is intended to guide conversation in the most efficient way.
In some situations additional software that is not used only for PSMs may be incorporated into the problem structuring process; examples include spreadsheet modeling, system dynamics software or geographic information systems. Some practitioners, who have focused on building system dynamics simulation models with groups of people, have called their work group model building (GMB) and have concluded "that GMB is another PSM". GMB has also been used in combination with SODA.

Given a particular problem formulation, how do we know whether all important elements have been included in the set? In short, how do we know when we have formulated an approximate solution to the right problem, as distinguished from an exact solution to the wrong problem?"
