74-616: Design research emerged as a recognisable field of study in the 1960s, initially marked by a conference on Design methods at Imperial College London , in 1962. It led to the founding of the Design Research Society (DRS) in 1966. John Christopher Jones (one of the initiators of the 1962 conference) founded a postgraduate Design Research Laboratory at the University of Manchester Institute of Science and Technology , and L. Bruce Archer supported by Misha Black founded

148-435: A design process: Methods of exploring design situations (e.g. Stating Objectives, Investigating User Behaviour, Interviewing Users), Methods of searching for ideas (e.g. Brainstorming, Synectics, Morphological Charts), Methods of exploring problem structure (e.g. Interaction Matrix, Functional Innovation, Information Sorting), Methods of evaluation (e.g. Checklists, Ranking and Weighting). Nigel Cross outlined eight stages in

222-434: A final design. In industrial and product design, process models tend to comprise a sequence of stages of divergent and convergent thinking. The Dubberly Design Office has compiled examples of more than 80 design process models, but it is not an exhaustive list. Within these process models, numerous design methods can be applied. In his book of 'Design Methods' J. C. Jones grouped 26 methods according to their purposes within

296-440: A hypothesis in the form of a rule that could have been used to create that triplet of numbers. When testing their hypotheses, participants tended to only create additional triplets of numbers that would confirm their hypotheses, and tended not to create triplets that would negate or disprove their hypotheses. Mental set is the inclination to re-use a previously successful solution, rather than search for new and better solutions. It

370-496: A hypothesis with empirical data (asking "how much?"). The objective of abduction is to determine which hypothesis or proposition to test, not which one to adopt or assert. In the Peircean logical system, the logic of abduction and deduction contribute to our conceptual understanding of a phenomenon, while the logic of induction adds quantitative details (empirical substantiation) to our conceptual knowledge. Forensic engineering

444-664: A major growth in conferences, with not only a continuing series by DRS, but also series such as Design Thinking, Doctoral Education in Design, Design Computing and Cognition, Design and Emotion, the European Academy, the Asian Design Conferences, etc. Design research now operates on an international scale, acknowledged in the cooperation of DRS with the Asian design research societies in the founding in 2005 of

518-502: A problem and creating a solution: the more widespread and inconvenient the problem, the greater the opportunity to develop a scalable solution. There are many specialized problem-solving techniques and methods in fields such as science , engineering , business , medicine , mathematics , computer science , philosophy , and social organization . The mental techniques to identify, analyze, and solve problems are studied in psychology and cognitive sciences . Also widely researched are

592-413: A process known as transfer . Problem-solving strategies are steps to overcoming the obstacles to achieving a goal. The iteration of such strategies over the course of solving a problem is the "problem-solving cycle". Common steps in this cycle include recognizing the problem, defining it, developing a strategy to fix it, organizing knowledge and resources available, monitoring progress, and evaluating

666-503: A process of engineering product design, each with an associated method: Identifying Opportunities - User Scenarios; Clarifying Objectives - Objectives Tree; Establishing Functions - Function Analysis; Setting Requirements - Performance Specification; Determining Characteristics - Quality Function Deployment; Generating Alternatives - Morphological Chart; Evaluating Alternatives - Weighted Objectives; Improving Details - Value Engineering. Many design methods still currently in use originated in

740-594: A product or process prior to an actual failure event—to predict, analyze, and mitigate a potential problem in advance. Techniques such as failure mode and effects analysis can proactively reduce the likelihood of problems. In either the reactive or the proactive case, it is necessary to build a causal explanation through a process of diagnosis. In deriving an explanation of effects in terms of causes, abduction generates new ideas or hypotheses (asking "how?"); deduction evaluates and refines hypotheses based on other plausible premises (asking "why?"); and induction justifies

814-488: A summary model consisting of three phases: Analytical phase (programming and data collection, analysis), Creative phase (synthesis, development), and Executive phase (communication). The UK's Design Council models the creative design process in four phases: Discover (insight into the problem), Define (the area to focus upon), Develop (potential solutions), and Deliver (solutions that work). A systematic model for engineering design by Pahl and Beitz has phases of Clarification of

888-399: A systematic process of designing. These process models usually comprise a number of phases or stages, beginning with a statement or recognition of a problem or a need for a new design and culminating in a finalised solution proposal. In his 'Systematic Method for Designers' L. Bruce Archer produced a very elaborate, 229 step model of a systematic design process for industrial design, but also

962-442: A type of mental set known as functional fixedness (see the following section). Rigidly clinging to a mental set is called fixation , which can deepen to an obsession or preoccupation with attempted strategies that are repeatedly unsuccessful. In the late 1990s, researcher Jennifer Wiley found that professional expertise in a field can create a mental set, perhaps leading to fixation. Groupthink , in which each individual takes on

1036-400: Is a reliance on habit. It was first articulated by Abraham S. Luchins in the 1940s with his well-known water jug experiments. Participants were asked to fill one jug with a specific amount of water by using other jugs with different maximum capacities. After Luchins gave a set of jug problems that could all be solved by a single technique, he then introduced a problem that could be solved by

1110-547: Is an example of simple problem solving (SPS) addressing one issue, whereas the latter is complex problem solving (CPS) with multiple interrelated obstacles. Another classification of problem-solving tasks is into well-defined problems with specific obstacles and goals, and ill-defined problems in which the current situation is troublesome but it is not clear what kind of resolution to aim for. Similarly, one may distinguish formal or fact-based problems requiring psychometric intelligence , versus socio-emotional problems which depend on

1184-412: Is an important technique of failure analysis that involves tracing product defects and flaws. Corrective action can then be taken to prevent further failures. Reverse engineering attempts to discover the original problem-solving logic used in developing a product by disassembling the product and developing a plausible pathway to creating and assembling its parts. In military science , problem solving

1258-573: Is an unintentional tendency to collect and use data which favors preconceived notions. Such notions may be incidental rather than motivated by important personal beliefs: the desire to be right may be sufficient motivation. Scientific and technical professionals also experience confirmation bias. One online experiment, for example, suggested that professionals within the field of psychological research are likely to view scientific studies that agree with their preconceived notions more favorably than clashing studies. According to Raymond Nickerson, one can see

1332-554: Is dependent upon personal motivational and contextual components. One such component is the emotional valence of "real-world" problems, which can either impede or aid problem-solving performance. Researchers have focused on the role of emotions in problem solving, demonstrating that poor emotional control can disrupt focus on the target task, impede problem resolution, and lead to negative outcomes such as fatigue, depression, and inertia. In conceptualization, human problem solving consists of two related processes: problem orientation, and

1406-433: Is linked to the concept of "end-states", the conditions or situations which are the aims of the strategy. Ability to solve problems is important at any military rank , but is essential at the command and control level. It results from deep qualitative and quantitative understanding of possible scenarios. Effectiveness in this context is an evaluation of results: to what extent the end states were accomplished. Planning

1480-460: Is not necessarily common. Mathematical word problems often include irrelevant qualitative or numerical information as an extra challenge. The disruption caused by the above cognitive biases can depend on how the information is represented: visually, verbally, or mathematically. A classic example is the Buddhist monk problem: A Buddhist monk begins at dawn one day walking up a mountain, reaches

1554-407: Is one of the most common forms of cognitive bias in daily life. As an example, imagine a man wants to kill a bug in his house, but the only thing at hand is a can of air freshener. He may start searching for something to kill the bug instead of squashing it with the can, thinking only of its main function of deodorizing. Tim German and Clark Barrett describe this barrier: "subjects become 'fixed' on

1628-438: Is the dot problem: nine dots arranged in a three-by-three grid pattern must be connected by drawing four straight line segments, without lifting pen from paper or backtracking along a line. The subject typically assumes the pen must stay within the outer square of dots, but the solution requires lines continuing beyond this frame, and researchers have found a 0% solution rate within a brief allotted time. This problem has produced

1702-563: Is the process of determining how to effect those end states. Some models of problem solving involve identifying a goal and then a sequence of subgoals towards achieving this goal. Andersson, who introduced the ACT-R model of cognition, modelled this collection of goals and subgoals as a goal stack in which the mind contains a stack of goals and subgoals to be completed, and a single task being carried out at any time. Knowledge of how to solve one problem can be applied to another problem, in

1776-489: Is the work of Allen Newell and Herbert A. Simon . Experiments in the 1960s and early 1970s asked participants to solve relatively simple, well-defined, but not previously seen laboratory tasks. These simple problems, such as the Tower of Hanoi , admitted optimal solutions that could be found quickly, allowing researchers to observe the full problem-solving process. Researchers assumed that these model problems would elicit

1850-470: Is to find and fix errors in computer programs: debugging . Formal logic concerns issues like validity, truth, inference, argumentation, and proof. In a problem-solving context, it can be used to formally represent a problem as a theorem to be proved, and to represent the knowledge needed to solve the problem as the premises to be used in a proof that the problem has a solution. The use of computers to prove mathematical theorems using formal logic emerged as

1924-510: The University of California, Berkeley . The DMG held a conference at MIT in 1968 with a focus on environmental design and planning, and that led to the foundation of the Environmental Design Research Association (EDRA), which held its first conference in 1969. A group interested in design methods and theory in architecture and engineering formed at MIT in the early 1980s, including Donald Schön , who

1998-949: The advice taker , to represent information in formal logic and to derive answers to questions using automated theorem-proving. An important step in this direction was made by Cordell Green in 1969, who used a resolution theorem prover for question-answering and for such other applications in artificial intelligence as robot planning. The resolution theorem-prover used by Cordell Green bore little resemblance to human problem solving methods. In response to criticism of that approach from researchers at MIT, Robert Kowalski developed logic programming and SLD resolution , which solves problems by problem decomposition. He has advocated logic for both computer and human problem solving and computational logic to improve human thinking. When products or processes fail, problem solving techniques can be used to develop corrective actions that can be taken to prevent further failures . Such techniques can also be applied to

2072-604: The "science of design" as "a body of intellectually tough, analytic, partly formalizable, partly empirical, teachable doctrine about the design process", whereas Jones catalogued a variety of approaches to design, both rational and creative, within a context of a broad, futures creating, systems view of design. The 1970s saw some reaction against the rationality of design methods, notably from two of its pioneers, Christopher Alexander and J. Christopher Jones . Fundamental issues were also raised by Rittel, who characterised design and planning problems as wicked problems , un-amenable to

2146-560: The 1962 Conference on Design Methods, the Design Research Society (DRS) was founded in the UK in 1966. The purpose of the Society is to promote "the study of and research into the process of designing in all its many fields" and is an interdisciplinary group with many professions represented. In the USA, a similar Design Methods Group (DMG) was also established in 1966 by Horst Rittel and others at

2220-503: The 1980s, and has continued to expand. This was helped by the development of a research base, including doctoral programmes, within many of the design schools located within new institutions that were previously art colleges, and the emergence of new areas such as interaction design. More new journals have appeared, such as The Design Journal , the Journal of Design Research , CoDesign and more recently Design Science . There has also been

2294-705: The Design Society. Academic research journals in design also began publication. DRS initiated Design Studies in 1979, Design Issues appeared in 1984, and Research in Engineering Design in 1989. Several pioneers of design methods developed their work in association with industry. The Ulm school established a significant partnership with the German consumer products company Braun through their designer Dieter Rams . J. Christopher Jones began his approach to systematic design as an ergonomist at

2368-534: The International Association of Societies of Design Research. Design methods Design methods are procedures, techniques, aids, or tools for designing. They offer a number of different kinds of activities that a designer might use within an overall design process. Conventional procedures of design, such as drawing, can be regarded as design methods, but since the 1950s new procedures have been developed that are more usually grouped under

2442-828: The Japanese Society for the Science of Design had been established as early as 1954. Books on systematic engineering design methods were published in Germany and the UK. In the USA the American Society of Mechanical Engineers Design Engineering Division began a stream on design theory and methodology within its annual conferences. The interest in systematic, rational approaches to design has led to design science and design science (methodology) in engineering and computer science. The development of design methods has been closely associated with prescriptions for

2516-419: The changeable emotions of individuals or groups, such as tactful behavior, fashion, or gift choices. Solutions require sufficient resources and knowledge to attain the goal. Professionals such as lawyers, doctors, programmers, and consultants are largely problem solvers for issues that require technical skills and knowledge beyond general competence. Many businesses have found profitable markets by recognizing

2590-800: The characteristic cognitive processes by which more complex "real world" problems are solved. An outstanding problem-solving technique found by this research is the principle of decomposition . Much of computer science and artificial intelligence involves designing automated systems to solve a specified type of problem: to accept input data and calculate a correct or adequate response, reasonably quickly. Algorithms are recipes or instructions that direct such systems, written into computer programs . Steps for designing such systems include problem determination, heuristics , root cause analysis , de-duplication , analysis, diagnosis, and repair. Analytic techniques include linear and nonlinear programming, queuing systems , and simulation. A large, perennial obstacle

2664-626: The consequences of confirmation bias in real-life situations, which range in severity from inefficient government policies to genocide. Nickerson argued that those who killed people accused of witchcraft demonstrated confirmation bias with motivation. Researcher Michael Allen found evidence for confirmation bias with motivation in school children who worked to manipulate their science experiments to produce favorable results. However, confirmation bias does not necessarily require motivation. In 1960, Peter Cathcart Wason conducted an experiment in which participants first viewed three numbers and then created

2738-457: The correct use of a tool. Unnecessary constraints are arbitrary boundaries imposed unconsciously on the task at hand, which foreclose a productive avenue of solution. The solver may become fixated on only one type of solution, as if it were an inevitable requirement of the problem. Typically, this combines with mental set—clinging to a previously successful method. Visual problems can also produce mentally invented constraints. A famous example

2812-622: The design function of the objects, and problem solving suffers relative to control conditions in which the object's function is not demonstrated." Their research found that young children's limited knowledge of an object's intended function reduces this barrier Research has also discovered functional fixedness in educational contexts, as an obstacle to understanding: "functional fixedness may be found in learning concepts as well as in solving chemistry problems." There are several hypotheses in regards to how functional fixedness relates to problem solving. It may waste time, delaying or entirely preventing

2886-447: The design methods movement of the 1960s and 70s, adapted to modern design practices. Recent developments have seen the introduction of more qualitative techniques, including ethnographic methods such as cultural probes and situated methods. The design methods movement had a profound influence on the development of academic interest in design and designing and the emergence of design research and design studies . Arising directly from

2960-581: The design profession. Wide influence has also come through Christopher Alexander 's pattern language method, originally developed for architectural and urban design, which has been adopted in software design , interaction design , pedagogical design and other domains. Problem solving Problem solving is the process of achieving a goal by overcoming obstacles, a frequent part of most activities. Problems in need of solutions range from simple personal tasks (e.g. how to turn on an appliance) to complex issues in business and technical fields. The former

3034-423: The effectiveness of the solution. Once a solution is achieved, another problem usually arises, and the cycle starts again. Insight is the sudden a ha! solution to a problem, the birth of a new idea to simplify a complex situation. Solutions found through insight are often more incisive than those from step-by-step analysis. A quick solution process requires insight to select productive moves at different stages of

3108-565: The electrical engineering company AEI . L. Bruce Archer developed his systematic approach in projects for medical equipment for the UK National Health Service. In the USA, designer Henry Dreyfuss had a profound impact on the practice of industrial design by developing systematic processes and promoting the use of anthropometrics , ergonomics and human factors in design, including through his 1955 book 'Designing for People'. Another successful designer, Jay Doblin ,

3182-509: The establishment of design as a coherent discipline of study in its own right, based on the view that design has its own things to know and its own ways of knowing them. Bruce Archer again encapsulated the view in stating his new belief that ‘there exists a designerly way of thinking and communicating that is both different from scientific and scholarly ways of thinking and communicating, and as powerful as scientific and scholarly methods of enquiry when applied to its own kinds of problems’. This view

3256-424: The expression " think outside the box ". Such problems are typically solved via a sudden insight which leaps over the mental barriers, often after long toil against them. This can be difficult depending on how the subject has structured the problem in their mind, how they draw on past experiences, and how well they juggle this information in their working memory. In the example, envisioning the dots connected outside

3330-604: The field of automated theorem proving in the 1950s. It included the use of heuristic methods designed to simulate human problem solving, as in the Logic Theory Machine , developed by Allen Newell, Herbert A. Simon and J. C. Shaw, as well as algorithmic methods such as the resolution principle developed by John Alan Robinson . In addition to its use for finding proofs of mathematical theorems, automated theorem-proving has also been used for program verification in computer science. In 1958, John McCarthy proposed

3404-571: The founding of the Design Research Society and influencing design education and practice. Leading figures in this movement in the UK were J. Christopher Jones at the University of Manchester and L. Bruce Archer at the Royal College of Art . The movement developed through further conferences on new design methods in the UK and USA in the 1960s. The first books on rational design methods, and on creative methods also appeared in this period. New approaches to design were developing at

3478-421: The framing square requires visualizing an unconventional arrangement, which is a strain on working memory. Irrelevant information is a specification or data presented in a problem that is unrelated to the solution. If the solver assumes that all information presented needs to be used, this often derails the problem solving process, making relatively simple problems much harder. For example: "Fifteen percent of

3552-431: The growing advocacy of systematic methods of problem solving, borrowed from computer techniques and management theory, for the assessment of design problems and the development of design solutions.’ Herbert A. Simon established the foundations for ‘a science of design ’, which would be ‘a body of intellectually tough, analytic, partly formalizable, partly empirical, teachable doctrine about the design process.’ Early work

3626-405: The human problem-solving processes using methods such as introspection , behaviorism , simulation , computer modeling , and experiment . Social psychologists look into the person-environment relationship aspect of the problem and independent and interdependent problem-solving methods. Problem solving has been defined as a higher-order cognitive process and intellectual function that requires

3700-812: The mental obstacles that prevent people from finding solutions; problem-solving impediments include confirmation bias , mental set , and functional fixedness . The term problem solving has a slightly different meaning depending on the discipline. For instance, it is a mental process in psychology and a computerized process in computer science . There are two different types of problems: ill-defined and well-defined; different approaches are used for each. Well-defined problems have specific end goals and clearly expected solutions, while ill-defined problems do not. Well-defined problems allow for more initial planning than ill-defined problems. Solving problems sometimes involves dealing with pragmatics (the way that context contributes to meaning) and semantics (the interpretation of

3774-517: The mid-20th Century, and also in response to industrialisation and mass-production, which changed the nature of designing. A "Conference on Systematic and Intuitive Methods in Engineering, Industrial Design, Architecture and Communications", held in London in 1962 is regarded as a key event marking the beginning of what became known within design studies as the "design methods movement", leading to

3848-466: The mindset of the rest of the group, can produce and exacerbate mental set. Social pressure leads to everybody thinking the same thing and reaching the same conclusions. Functional fixedness is the tendency to view an object as having only one function, and to be unable to conceive of any novel use, as in the Maier pliers experiment described above. Functional fixedness is a specific form of mental set, and

3922-471: The modulation and control of more routine or fundamental skills. Empirical research shows many different strategies and factors influence everyday problem solving. Rehabilitation psychologists studying people with frontal lobe injuries have found that deficits in emotional control and reasoning can be re-mediated with effective rehabilitation and could improve the capacity of injured persons to resolve everyday problems. Interpersonal everyday problem solving

3996-458: The monk's progress on each day. It becomes much easier when the paragraph is represented mathematically by a function: one visualizes a graph whose horizontal axis is time of day, and whose vertical axis shows the monk's position (or altitude) on the path at each time. Superimposing the two journey curves, which traverse opposite diagonals of a rectangle, one sees they must cross each other somewhere. The visual representation by graphing has resolved

4070-584: The motivational/attitudinal/affective approach to problematic situations and problem-solving skills. People's strategies cohere with their goals and stem from the process of comparing oneself with others. Among the first experimental psychologists to study problem solving were the Gestaltists in Germany , such as Karl Duncker in The Psychology of Productive Thinking (1935). Perhaps best known

4144-403: The name of "design methods". What design methods have in common is that they "are attempts to make public the hitherto private thinking of designers; to externalise the design process". Design methodology is the broader study of method in design: the study of the principles, practices and procedures of designing. Design methods originated in new approaches to problem solving developed in

4218-485: The people in Topeka have unlisted telephone numbers. You select 200 names at random from the Topeka phone book. How many of these people have unlisted phone numbers?" The "obvious" answer is 15%, but in fact none of the unlisted people would be listed among the 200. This kind of " trick question " is often used in aptitude tests or cognitive evaluations. Though not inherently difficult, they require independent thinking that

4292-403: The postgraduate Department of Design Research at the Royal College of Art , London, becoming the first Professor of Design Research. The Design Research Society has always stated its aim as: ‘to promote the study of and research into the process of designing in all its many fields’. Its purpose therefore is to act as a form of learned society , taking a scholarly and domain independent view of

4366-447: The problem). The ability to understand what the end goal of the problem is, and what rules could be applied, represents the key to solving the problem. Sometimes a problem requires abstract thinking or coming up with a creative solution. Problem solving has two major domains: mathematical problem solving and personal problem solving. Each concerns some difficulty or barrier that is encountered. Problem solving in psychology refers to

4440-491: The problem-solving cycle. Unlike Newell and Simon's formal definition of a move problem , there is no consensus definition of an insight problem . Some problem-solving strategies include: Common barriers to problem solving include mental constructs that impede an efficient search for solutions. Five of the most common identified by researchers are: confirmation bias , mental set , functional fixedness , unnecessary constraints, and irrelevant information. Confirmation bias

4514-469: The process of designing. Some of the origins of design methods and design research lay in the emergence after the 2nd World War of operational research methods and management decision-making techniques, the development of creativity techniques in the 1950s, and the beginnings of computer programs for problem solving in the 1960s. A statement by Bruce Archer encapsulated what was going on: ‘The most fundamental challenge to conventional ideas on design has been

SECTION 60

#1732791187797

4588-582: The process of finding solutions to problems encountered in life. Solutions to these problems are usually situation- or context-specific. The process starts with problem finding and problem shaping , in which the problem is discovered and simplified. The next step is to generate possible solutions and evaluate them. Finally a solution is selected to be implemented and verified. Problems have an end goal to be reached; how you get there depends upon problem orientation (problem-solving coping style and skills) and systematic analysis. Mental health professionals study

4662-592: The publications of the Design Methods Group and the series of conferences of the Environmental Design Research Association . The National Science Foundation initiative on design theory and methods led to substantial growth in engineering design research in the late-1980s. A particularly significant development was the emergence of the first journals of design research: Design Studies in 1979, Design Issues in 1984, and Research in Engineering Design in 1989. The development of design research has led to

4736-595: The role of design thinking as a creative process in problem solving and innovation. However, interest in systematic and rational design methods continued to develop strongly in engineering design during the 1980s; for example, through the Conference on Engineering Design series of The Design Society and the work of the Verein Deutscher Ingenieure association in Germany, and also in Japan, where

4810-486: The same technique, but also by a novel and simpler method. His participants tended to use the accustomed technique, oblivious of the simpler alternative. This was again demonstrated in Norman Maier 's 1931 experiment, which challenged participants to solve a problem by using a familiar tool (pliers) in an unconventional manner. Participants were often unable to view the object in a way that strayed from its typical use,

Design teaching at Ulm integrated design with science (including social sciences) and introduced new fields of study such as cybernetics , systems theory and semiotics into design education. Bruce Archer also taught at Ulm, and another influential teacher

4958-456: The task, Conceptual design, Embodiment design, and Detail design. A less prescriptive approach to designing a basic design process for oneself has been outlined by J. Christopher Jones . In the engineering design process systematic models tend to be linear, in sequential steps, but acknowledging the necessity of iteration. In architectural design, process models tend to be cyclical and spiral, with iteration as essential to progression towards

5032-410: The techniques of science and engineering, which deal with "tame" problems. The criticisms turned some in the movement away from rationalised approaches to design problem solving and towards "argumentative", participatory processes in which designers worked in partnership with the problem stakeholders (clients, customers, users, the community). This led to participatory design , user centered design and

In 1963 Rittel moved to the School of Architecture at the University of California, Berkeley , where he helped found the Design Methods Group, a society focused on developing and promoting new methods especially in architecture and planning. At the end of the 1960s two influential, but quite different works were published: Herbert A. Simon 's The Sciences of the Artificial and J. Christopher Jones 's Design Methods . Simon proposed

5254-467: Was also influential on the theory and practice of design as a systematic process. Much of current design practice has been influenced and guided by design methods. For example, the influential IDEO consultancy uses design methods extensively in its 'Design Kit' and 'Method Cards'. Increasingly, the intersections of design methods with business and government through the application of design thinking have been championed by numerous consultancies within

5328-524: Was developed further in a series of papers by Nigel Cross , collected as a book on 'Designerly Ways of Knowing'. Significantly, Donald Schön promoted the new view within his book The Reflective Practitioner, in which he challenged the technical rationality of Simon and sought to establish ‘an epistemology of practice implicit in the artistic, intuitive processes which [design and other] practitioners bring to situations of uncertainty, instability, uniqueness and value conflict’. Design research ‘came of age’ in

5402-427: Was mainly within the domains of architectural design and industrial design . Research in engineering design developed strongly in the 1980s, for example, through ICED—the series of International Conferences on Engineering Design, now run by The Design Society. These developments were especially strong in Germany and Japan. In the USA there were also some important developments in design theory and methodology, including

5476-710: Was studying the working practices of architects, engineers and other professionals and developing his theory of reflective practice . In 1984 the National Science Foundation created a Design Theory and Methodology Program to promote methods and process research in engineering design. Meanwhile in Europe, Vladimir Hubka established the Workshop Design-Konstruction (WDK),which led to a series of International Conferences on Engineering Design (ICED) beginning in 1981 and later became
