Design process
Substantial disagreement exists concerning how designers in many fields, whether amateur or professional, alone or in teams, produce designs. Design researchers Dorst and Dijkhuis acknowledge that "there are many ways of describing design processes", and compare and contrast two dominant but different views of the design process: as a rational problem solving process and as a process of reflection-in-action. They suggested that these two paradigms "represent two fundamentally different ways of looking at the world positivism and constructionism". The paradigms may reflect differing views of how designing ''should be'' done and how it ''actually is'' done, and they both have a variety of names. The problem-solving view has been called "the rational model",
"technical rationality"
and "the reason-centric perspective".
The alternative view has been called "reflection-in-action",
"co-evolution",
[ and "the action-centric perspective".]
Rational model
The rational model was independently developed by Herbert A. Simon,[Simon, H.A. (1996]
The sciences of the artificial
, MIT Press, Cambridge, MA, USA. p. 111. . an American scientist, and two German engineering design theorists, Gerhard Pahl and Wolfgang Beitz. It posits that:
# Designers attempt to optimize a design candidate for known constraints and objectives.
# The design process is plan-driven.
# The design process is understood in terms of a discrete sequence of stages.
The rational model is based on a rationalist philosophy

Typical stages consistent with the rational model include the following:

Criticism of the rational model
The rational model has been widely criticized on two primary grounds:
# Designers do not work this way – extensive empirical evidence has demonstrated that designers do not act as the rational model suggests.[
# Unrealistic assumptions – goals are often unknown when a design project begins, and the requirements and constraints continue to change.]
Action-centric model
The action-centric perspective is a label given to a collection of interrelated concepts, which are antithetical to the rational model. It posits that:
# Designers use creativity
Creativity is a phenomenon whereby something new and valuable is formed. The created item may be intangible (such as an idea, a scientific theory, a musical composition, or a joke) or a physical object (such as an invention, a printed literary w ...

.
# No universal sequence of stages is apparent – analysis, design and implementation are contemporary and inextricably linked.
The action-centric perspective is based on an empiricist philosophy and broadly consistent with the agile approach[ and methodical development.][ Substantial empirical evidence supports the veracity of this perspective in describing the actions of real designers.][ Like the rational model, the action-centric model sees design as informed by research and knowledge.
At least two views of design activity are consistent with the action-centric perspective. Both involve these three basic activities:
* In the reflection-in-action paradigm, designers alternate between " framing", "making moves", and "evaluating moves". "Framing" refers to conceptualizing the problem, i.e., defining goals and objectives. A "move" is a tentative design decision. The evaluation process may lead to further moves in the design.]
* In the sensemaking–coevolution–implementation framework, designers alternate between its three titular activities. Sensemaking
Sensemaking or sense-making is the process by which people give meaning to their collective experiences. It has been defined as "the ongoing retrospective development of plausible images that rationalize what people are doing" ( Weick, Sutcliffe, ...
includes both framing and evaluating moves. Implementation is the process of constructing the design object. Coevolution is "the process where the design agent simultaneously refines its mental picture of the design object based on its mental picture of the context, and vice versa".
The concept of the design cycle
A decision cycle is a sequence of steps used by an entity on a repeated basis to reach and implement decisions and to learn from the results. The "decision cycle" phrase has a history of use to broadly categorize various methods of making decision ...
is understood as a circular time structure, which may start with the thinking of an idea, then expressing it by the use of visual or verbal means of communication (design tools), the sharing and perceiving of the expressed idea, and finally starting a new cycle with the critical rethinking of the perceived idea. Anderson points out that this concept emphasizes the importance of the means of expression, which at the same time are means of perception of any design ideas.
Philosophies
Philosophy of design is the study of definitions of design, and the assumptions, foundations, and implications of design. There are also many informal 'philosophies' for guiding design such as personal values or preferred approaches.
Approaches to design
Some of these values and approaches include:
* Critical design uses designed artifacts as an embodied critique or commentary on existing values, morals, and practices in a culture.
* Ecological design
Ecological design or ecodesign is an approach to designing products and services that gives special consideration to the environmental impacts of a product over its entire lifecycle. Sim Van der Ryn and Stuart Cowan define it as "any form of des ...

(originally co-operative design, now often co-design) is the practice of collective creativity to design, attempting to actively involve all stakeholders (e.g. employees, partners, customers, citizens, end-users) in the design process to help ensure the result meets their needs and is usable.
* Scientific design refers to industrialised design based on scientific knowledge. Science can be used to study the effects and need for a potential or existing product in general and to design products that are based on scientific knowledge. For instance, a scientific design of face masks for COVID-19 mitigation may be based on investigations of filtration performance, mitigation performance, thermal comfort, biodegradability
