{{Short description|Set of procedures, techniques, aids, or tools for designing}}

'''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 together under 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".<ref name="Jones Design Methods">{{cite book |last1=Jones |first1=J. Christopher |title=Design Methods |url=https://archive.org/details/ilmontanarodelg00castgoog |date=1980 |publisher=Wiley |___location=UK}}</ref>

''Design methodology'' is the broader study of method in design: the study of the principles, practices and procedures of designing.<ref name="Cross Methodology">{{cite book |last1=Cross |first1=Nigel |title=Developments in Design Methodology |date=1984 |publisher=Wiley |___location=UK |isbn=978-0471102489}}</ref>

The 1970s saw some reaction against the rationality of design methods, notably from two of its pioneers, [[Christopher Alexander]] and [[John Christopher Jones|J. Christopher Jones]].<ref>Cross, N. (1984) ''Developments in Design Methodology'', Wiley, UK.</ref> Fundamental issues were also raised by Rittel, who characterised design and planning problems as [[wicked problems]], un-amenable to the techniques of science and engineering, which deal with "tame" problems.<ref>Rittel, H. and M. Webber (1973) "Dilemmas in a General Theory of Planning", ''Policy Sciences'' '''4''', 155–169</ref> 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 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 the Japanese Society for the Science of Design had been established as early as 1954.<ref>{{Cite web | url=https://iasdr.net/member-societies/ | title=IASDR}}</ref> Books on systematic engineering design methods were published in Germany and the UK.<ref>Hubka, V.

(1989) ''Engineering Design Methods'', Wiley, UK.</ref> 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.

==Methods and Processesprocesses==

The development of design methods has been closely associated with prescriptions for 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,<ref>{{Cite web | url=http://www.dubberly.com/concept-maps/archers-design-process.html | title=Bruce Archer's Design Process Checklist}}</ref> but also 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]] modelscreated the [[Double Diamond (design process model)]], which breaks the creative design process ininto four phases: Discover (insight into the problem), Define (the area to focus upon), Develop (potential solutions), and Deliver (solutions that work).<ref>{{Cite web | url=https://www.designcouncil.org.uk/news-opinion/design-process-what-double-diamond | title=The Design Process: What is the Double Diamond?| date=2015-03-17}}</ref> A systematic model for engineering design by Pahl and Beitz has phases of Clarification of the task, Conceptual design, Embodiment design, and Detail design.<ref>Pahl, G. and W. Beitz (1984) ''Engineering Design: a systematic approach'', Springer/Design Council, UK.</ref> A less prescriptive approach to designing a basic design process for oneself has been outlined by [[John Christopher Jones|J. Christopher Jones]].<ref>{{cite web |last1=Jones |first1=J. Christopher|title=design methods for everyone |url=http://publicwriting.net/2.2/designmethodsforeveryone.html|website=publicwriting.net |accessdateaccess-date=21 December 2018}}</ref>

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 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,<ref>Dubberly, H. (2004) ''How do you design: a compendium of models''. Dubberly Design Office, San Francisco, USA. http://www.dubberly.com/wp-content/uploads/2008/06/ddo_designprocess.pdf</ref> but it is not an exhaustive list.

Within these process models there are, numerous design methods that can be applied. In his book of 'Design Methods' [[John Christopher Jones|J. C. Jones]] grouped 26 methods according to their purposes within 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).<ref>Jones, J. C. (1970) ''Design Methods: seeds of human futures''. Wiley, UK.</ref>

[[Nigel Cross]] outlined eight stages in 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.<ref>Cross, N. (2008) ''Engineering Design Methods: Strategies for Product Design''. Wiley, UK.</ref>

In the USA, a similar Design Methods Group (DMG) was also established in 1966 by [[Horst Rittel]] and others at the [[University of California, Berkeley]]. The DMG held a conference at [[MIT]] in 1968<ref>Moore, G. T. (ed.) (1970) ''Emerging Methods in Environmental Design and Planning''. MIT Press, USA.</ref> 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 was studying the working practices of architects, engineers and other professionals and developing his theory of [[reflective practice]].<ref>Schön, D. A. (1983)''The Reflective Practitioner: How Professionals Think in Action''. New York: Basic Books. {{ISBN|0-465-06878-2}}.</ref> 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 [[the Design Society]].

Academic research journals in design also began publication. DRS initiated ''Design Studies''<ref>{{Cite book | url=https://www.journals.elsevier.com/design-studies | title=Design Studies}}</ref> in 1979, ''Design Issues''<ref>{{Cite web | url=https://www.mitpressjournals.org/loi/desi | title=MIT Press Journals}}</ref> appeared in 1984, and ''Research in Engineering Design''<ref>{{Cite web|url=https://link.springer.com/journal/163|title = Research in Engineering Design}}</ref> in 1989.

==Influence on all professional design practice==

Several pioneers of design methods developed their work in association with industry. The [[Ulm School of Design|Ulm school]] established a significant partnership with the German consumer products company [[Braun (company)|Braun]] through their designer [[Dieter Rams]]. [[John Christopher Jones|J. Christopher Jones]] began his approach to systematic design as an ergonomist at the electrical engineering company [[Associated Electrical Industries|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'.<ref>Dreyfuss, Henry. ''Designing for People''. Allworth Press; 2003. {{ISBN|1-58115-312-0}}</ref> Another successful designer, [[Jay Doblin]], was also influential on the theory and practice of design as a systematic process.<ref>https://www.doblin.com/dist/images/uploads/A-Short-Grandiose-Theory-of-Design-J.-Doblin.pdf {{Webarchive|url=https://web.archive.org/web/20220818022033/https://doblin.com/dist/images/uploads/A-Short-Grandiose-Theory-of-Design-J.-Doblin.pdf |date=2022-08-18 }} {{Bare URL PDF|date=March 2022}}</ref>

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'.<ref>{{Cite web | url=http://www.designkit.org//resources/1 | title=Design Kit | access-date=2018-12-20 | archive-date=2022-05-23 | archive-url=https://web.archive.org/web/20220523084621/https://www.designkit.org/resources/1 | url-status=dead }}</ref><ref>{{Cite web | url=https://www.ideo.com/post/method-cards | title=Method Cards}}</ref> Increasingly, the intersections of design methods with business and government through the application of [[design thinking]] have been championed by numerous consultancies within the design profession. Wide influence has also come through [[Christopher Alexander]]'s [[pattern language]] method,<ref>{{cite book |last1=Alexander |display-authors=et al |first1=Christopher |title=A Pattern Language |date=1977 |publisher=Oxford University Press |isbn=978-0-19-501919-3 |url-access=registration |url=https://archive.org/details/patternlanguage00chri }}</ref> originally developed for architectural and urban design, which has been adopted in [[software design patterns|software design]], [[interaction design pattern|interaction design]], [[Pedagogical patterns|pedagogical design]] and other domains.
