Design thinking stands for design-specific cognitive activities that designers apply during the process of designing.
Design thinking has come to be defined as combining empathy for the context of a problem, creativity in the generation of insights and solutions, and rationality in analyzing and fitting various solutions to the problem context. According to Tim Brown, CEO and president of IDEO, the goal of Design Thinking is "matching people’s needs with what is technologically feasible and viable as a business strategy"  The premise of teaching Design Thinking is that by knowing about how to successfully approach and solve difficult, multi-dimensional problems - more specifically, effective methods to ideate, select and execute solutions - individuals and businesses will be able to improve their own problem solving processes and skills. There is also significant academic interest in understanding how designers think and design cognition. The first formal academic research symposium on Design Thinking was organized at Delft University of Technology, The Netherlands, in 1991, and has developed into a regular series.
The notion of design as a "way of thinking" in the sciences can be traced to Herbert A. Simon's 1969 book The Sciences of the Artificial, and in design engineering to Robert McKim's 1973 book Experiences in Visual Thinking. Rolf Faste expanded on McKim's work at Stanford in the 80's and 90's, teaching "design thinking" as a method of creative action." Peter Rowe's 1987 book Design Thinking, which described methods and approaches used by architects and urban planners, was a significant early usage of the term in the design research literature. "Design Thinking" was adapted for business purposes by Faste's Stanford colleague David M. Kelley, who founded IDEO in 1991. Richard Buchanan's 1992 article, entitled "Wicked Problems in Design Thinking", expressed a broader view of "design thinking" as addressing intractable human concerns through design.
Design thinking is a formal method for practical, creative resolution of problems and creation of solutions, with the intent of an improved future result. In this regard it is a form of solution-based, or solution-focused thinking; starting with a goal (a better future situation) instead of solving a specific problem. By considering both present and future conditions and parameters of the problem, alternative solutions may be explored simultaneously. Cross asserted that this type of thinking most often happens in the built, or artificial, environment (as in artifacts).
This approach differs from the analytical scientific method, which begins with thoroughly defining all the parameters of the problem in order to create a solution. Design Thinking identifies and investigates with both known and ambiguous aspects of the current situation in order to discover hidden parameters and open alternative paths which may lead to the goal. Because Design Thinking is iterative, intermediate "solutions" are also potential starting points of alternative paths, including redefining of the initial problem.
In 1972 psychologist, architect and design researcher Bryan Lawson conducted an empirical study to investigate the difference between problem-focused solvers and solution-focused solvers. He took two groups of students – final year students in architecture and post-graduate science students – and asked them to create one-layer structures from a set of colored blocks. The perimeter of the structure had to optimize either the red or the blue color; however, there were unspecified rules governing the placement and relationship of some of the blocks.
Lawson found that:
The scientists adopted a technique of trying out a series of designs which used as many different blocks and combinations of blocks as possible as quickly as possible. Thus they tried to maximise the information available to them about the allowed combinations. If they could discover the rule governing which combinations of blocks were allowed they could then search for an arrangement which would optimise the required colour around the layout. [problem-focused] By contrast, the architects selected their blocks in order to achieve the appropriately coloured perimeter. If this proved not to be an acceptable combination, then the next most favourably coloured block combination would be substituted and so on until an acceptable solution was discovered. [solution-focused]
Nigel Cross concluded that Lawson's studies suggested that scientists problem solve by analysis, while designers problem solve by synthesis. Kelley and Brown argue that Design Thinking utilizes both analysis and synthesis.
The terms analysis and synthesis come from (classical) Greek and mean literally "to loosen up" and "to put together" respectively. In general, analysis is defined as the procedure by which we break down an intellectual or substantial whole into parts or components. Synthesis is defined as the opposite procedure: to combine separate elements or components in order to form a coherent whole. However, analysis and synthesis, as scientific methods, always go hand in hand; they complement one another. Every synthesis is built upon the results of a preceding analysis, and every analysis requires a subsequent synthesis in order to verify and correct its results.
Design Thinkers also use divergent thinking and convergent thinking to explore many possible solutions. Divergent thinking is the ability to offer different, unique or variant ideas adherent to one theme while convergent thinking is the ability to find the "correct" solution to the given problem. Design thinking encourages divergent thinking to ideate many solutions (possible or impossible) and then uses convergent thinking to prefer and realize the best resolution.
Unlike analytical thinking, design thinking is a process which includes the "building up" of ideas, with few, or no, limits on breadth during a "brainstorming" phase. This helps reduce fear of failure in the participant(s) and encourages input and participation from a wide variety of sources in the ideation phases. The phrase Outside the box thinking has been coined to describe one goal of the brainstorming phase and is encouraged, since this can aid in the discovery of hidden elements and ambiguities in the situation and discovering potentially faulty assumptions.
One version of the design thinking process has seven stages: define, research, ideate, prototype, choose, implement, and learn. Within these seven steps, problems can be framed, the right questions can be asked, more ideas can be created, and the best answers can be chosen. The steps aren't linear; can occur simultaneously and be repeated. A more simplified expression of the process is Robert McKim's phrase; "Express-Test-Cycle".
Although design is always influenced by individual preferences, the design thinking method shares a common set of traits, mainly; Creativity, Ambidextrous thinking, Teamwork, User-Centerdness (Empathy), Curiosity and Optimism.
An alternative, five phase, description of the process, as described by Hasso Plattner, is;
The path through these process steps is not strictly circular. Plattner states; "While the stages are simple enough, the adaptive expertise required to chose the right inflection points and appropriate next stage is a high order intellectual activity that requires practice and is learnable."
Plattner asserts that there are four rules to Design Thinking;
Design Thinking is especially useful when addressing what Buchanan referred to as "wicked problems". Wicked problems which are ill-defined or tricky, as opposed to wicked in the sense of malicious. With ill-defined problems, both the problem and the solution are unknown at the outset of the problem-solving exercise. This is as opposed to "tame" or "well-defined" problems where the problem is clear, and the solution is available through some technical knowledge.
For wicked problems, the general thrust of the problem may be clear, however considerable time and effort is spent in order to clarify the requirements. A large part of the problem solving activity, then, consists of problem definition and problem shaping.
The "a-ha Moment" is the moment where there is suddenly a clear forward path. It is the point in the cycle where synthesis and divergent thinking, analysis and convergent thinking, and the nature of the problem all come together and an appropriate resolution has been captured. Prior to this point, the process may seem nebulous, hazy and inexact. At this point, the path forward is so obvious that in retrospect it seems odd that it took so long to recognize it. After this point, the focus becomes more and more clear as the final product is constructed.
There are factors which can slow or halt the Design Thinking process; Fear, Resistance and Playing the Devil's Advocate. These attitudes introduce destructive negativity.
Fear of failure or criticism may prevent someone from even beginning apply methods and processes to achieve their goals. Both have psychological effects which divert someone from focusing on solutions and shifting their focus to doubts of self-worth, anxieties of "will it be good enough," or procrastination..."
Resistance can inhibit Design Thinking by reprioritizing the main goal and shifting efforts to other tasks which may need to be done. Donald Schön talks about the resistance of students towards their professors and the resistance of professors towards students in the learning process.
Playing the "Devil's Advocate" is constant nay-saying; making authoritative assertions as to why every proposed solution will not work. It is an embodiment of negative criticism. Devil's Advocates kill projects by shifting the focus from potential solutions to hypercritical issues with ambiguous effects. The goal is to stop further ideation towards a solution, which, according to Tom and Dave Kelley, ought to be "banned from the room".
Design methods and design process are often used interchangeably, but there are significant differences between the two.
Design methods are techniques, rules, or ways of doing things which are employed within a design discipline. The methods for Design Thinking include interviewing, creating user profiles, looking at other existing solutions, creating prototypes, mind-mapping, asking questions like the "Five-Whys" and situational analysis.
Because of Design Thinking's parallel nature, there are many different paths through the phases. This is part of the reason Design Thinking may seem to be "fuzzy" or "ambiguous" when compared to more analytical, Cartesian methods of science and engineering.
Some early Design Processes stemmed from Soft Systems Methodology in the 1960s. Koberg and Bagnall's wrote The All New Universal Traveller in 1972 and presented a circular, seven-step process to problem-solving. These seven steps could be done lineally or in feed-back loops. Stanford's d.school developed an updated seven step process in 2007. Other expressions of design processes have been proposed, including a three-step simplified triangular process (or the six-part, less simplified pyramid) by Bryan Lawson and Hugh Dubberly's e-book How Do You Design: A compendium of models.
Ill-defined problems often contain higher-order and obscure relationships. Design Thinking can address these through the use of analogies. An understanding of the expected results, or lack of domain-related knowledge for the task, may be developed by correlating different internal representations, such as images, to develop an understanding of the obscure or ill-defined elements of the situation. The process involves several complex cognitive mechanisms, as the design task often has elements in multiple cognitive domains—visual, mathematical, auditory or tactile—requiring the usage of multiple "languages", like visual thinking.
Although many design fields have been categorized as lying between Science and the Arts and Humanities, design may be seen as its own distinct way of understanding the world, based on solution-based problem solving, problem shaping, synthesis, and appropriateness in the built environment.
One of the first Design Science theorists, John Chris Jones, postulated that design was different than the arts, sciences and mathematics in the 1970s. In response to the question 'is designing an art, a science or a form of mathematics' Jones responded:
The main point of difference is that of timing. Both artists and scientists operate on the physical world as it exists in the present (whether it is real or symbolic), while mathematicians operate on abstract relationships that are independent of historical time. Designers, on the other hand, are forever bound to treat as real that which exists only in an imagined future and have to specify ways in which the foreseen thing can be made to exist.
Design can be seen as its own culture in education, with its own methods and ways of thinking which can be systematically taught in both K-12 and higher education. Nigel Cross sets out to show the differences between the humanities, the sciences, and design in his paper "Designerly Ways of Knowing". He observed that:
Conventionally, designers communicate mostly in visual or object languages. Gänshirt as well as Krazny have shown that even though most designers might use drawings, scale models or prototypes as their primary means of design, in practice an unlimited range of visual and verbal design tools is being used for design thinking. Symbols, signs, and metaphors are used through the medium of sketching, diagrams and technical drawings to translate abstract requirements into concrete objects. The way designers communicate, then, is through understanding this way of coding design requirements in order to produce built products.
Design thinking has two common interpretations in the business world:
The limits of the first kind of design thinking in business are also being explored. Not all problems yield to design thinking alone, where it may be a 'temporary fix'. Design thinking companies including IDEO and Sense Worldwide are responding to this by building business thinking capabilities.
In organization and management theory, design thinking forms part of the Architecture/Design/Anthropology (A/D/A) paradigm, which characterizes innovative, human-centered enterprises. This paradigm also focuses on a collaborative and iterative style of work and an abductive mode of thinking, compared to practices associated with the more traditional Mathematics/Economics/Psychology (M/E/P) management paradigm.
Companies that integrate the principles of design thinking in their innovation processes often share a certain mindset or are striving to cultivate a more creative and human-centred company culture.
Design Thinking has been suggested for use in schools in a variety of curricular ways, as well as for redesigning student spaces and school systems. Design thinking in education typically takes three forms: helping school administrators solve institution-based problems, aiding educators develop more creative lesson plans, and engendering design thinking skills in students. There are currently many researchers exploring the intersection of design thinking and education . The REDLab group, from Stanford University's Graduate School of Education, conducts research into design thinking in K-12, secondary, and post-secondary settings. The Hasso Plattner Design Thinking Research program is a collaborative program between Stanford University and the Hasso Plattner Institute from Potsdam, Germany. The Hasso Plattner Design Thinking Research Program’s mission is to “apply rigorous academic methods to understand how and why Design Thinking innovation works and fails.” In addition to enriching curriculum and expanding student perspectives, design thinking can also benefit educators. Researchers have proposed that design thinking can enable educators to integrate technology into the classroom. Design thinking as a viable curricular and systemic reform program, is increasingly being recognized by educators. "Much of today's education system guides students toward finding the correct answers to fill-in-the blanks on standardized tests, as this kind of instruction facilitates streamlined assessments to measure success or failure... It is critical that, particularly in under-served schools this model of learning does not continue to prevail. Students need both the skills and the tools to participate in a society where problems are increasingly complex and nuanced understandings are vital." 
Uses in K-12 Education
In the K-12 arena, design thinking is employed to promote creative thinking, team work, and student responsibility for learning. The non profit Tools at Schools aims to expose students, educators, and schools to design thinking. The organization does this by facilitating a relationship between a school and a manufacturing company. Over a minimum of six months, representatives from the manufacturing company teach students the principles of design and establish the kind of product to be designed. The students collaborate to design a prototype which is created by the manufacturer. Once the prototype arrives, the students must promote the product and support the ideas that lead to its design.
An example of the Tools at Schools partnership is the redesign of school equipment by 8th grade students at the School at Columbia University. The students were divided into groups and asked to redesign a locker, chair, or a desk to better suit the needs of 21st century pupils. The students' final products were displayed at the International Contemporary Furniture Fair where they demonstrated their product to fair attendees and industry professionals. Overall Tools for Schools not only introduces students to the design process, it exposes them to the design profession through their interactions with designers and manufacturers. Since the students work together in groups, design thinking in education also encourages collaborative learning.
Another organization that works with integrating design thinking for students is the corporation NoTosh. NoTosh has a Design Thinking School to teach instructors how to implement design thinking into their curriculum. One of the design thinking techniques NoTosh adopted from the corporate world and applied to education is hexagonal thinking. Hexagonal thinking consists of gathering cut-outs in hexagon shapes and writing a concept or fact on each one. Students then connect the hexagons by laying related ideas or facts together. The visual representation of relationships helps students better conceptualize wicked problems. Another concrete example of design thinking in action is NoTosh's "Googleable vs NonGoogleable Questions" exercise. Given a specific topic, students brainstorm questions on that issue and divide their questions into "Googleable and NonGoogleable."  Students research the Googleable questions and present their findings to the class while the NonGoogleable questions are used to create a project.
Stanford University's Taking Design Thinking to Schools Initiative
Apart from non profit entities and corporations, research universities are also involved in deploying design thinking curriculum to K-12 schools. Part of Stanford University’s efforts to incorporate design thinking in education into a hands-on setting is the Taking Design Thinking to Schools initiative. The Stanford School of Education and d.school partner with K-12 teachers in the Palo Alto area to discover ways to apply design thinking in an educational setting. “Teachers and students engage in hands-on design challenges that focus on developing empathy, promoting a bias towards action, encouraging ideation, developing metacognitive awareness and fostering active problem solving.” 
Taking Design Thinking to Schools identifies the following design thinking process:
By employing this process, the Stanford team and Taking Design Thinking to Schools participants collaborate to develop coursework that students will find engrossing and "hands-on."  Thus, the program at Stanford combines both design thinking for teachers who must create alternative curriculum and students who must complete the design thinking-based projects.
The K12 Lab at Stanford
The K12 Lab network is a part of the Stanford University d.school and according to its website its mission is to “inspire and develop the creative confidence of educators and support edu innovators catalyzing new models for teaching and learning.”  The K12 Lab Network publishes a wiki with information on creating design challenges for K-12 schools. The wiki provides tools for thinking about design challenges as well as criteria for implementing design challenges.
The Design Thinking for Educators Toolkit
The Design Thinking for Educators toolkit was developed in 2011 by the design firm IDEO in partnership with the PreK-12 independent school Riverdale Country School. The Design Thinking for Educators toolkit that is currently offered to the public for free download is the second version. The Design Thinking for Educators toolkit is a comprehensive resource for educators to use, which includes a “walk-through of the Design Thinking process complete with examples and a downloadable workbook.”  The toolkit has been used in academic research to aid in the creation of an "iPad learning Ecosystem.”  to help design a program to aid at-risk youth in the transition from elementary to secondary school, as well as to redesign libraries.
American Institute of Graphic Arts
The American Institute of Graphic Arts (AIGA) has implemented a movement, DesignEd K12, to take designing thinking to schools. This movement is guided by volunteers and there is not a specific program to follow; instead volunteer designers introduce students to the design field and consequently, design thinking. DesignEd K12 intends to motivate students to use design thinking to solve problems; to create a network where designers, students, and educational professionals share best practices; to shape a recommended approach to teaching design; and to cultivate a passion for design among young people  Across the nation, many of AIGA's chapters are working with school districts. The programs range in scope; some mentor students who have shown an interest in design, while other programs offer students the opportunity to explore design and participate in design thinking projects within scheduled classed or through an after-school activity.
Uses in Higher Education
Design thinking is currently being taught in "workshops, supplemental training, courses, or degree programs" in over 60 universities and colleges. Design Thinking is used by colleges as a way to instruct students on the phases of design, and to help develop innovative solutions to existing problems. The d.school at Stanford is a well-known design thinking program in higher education, with students from Stanford University's departments of engineering, medicine, business, law, and education utilizing the d.school to develop innovative solutions to problems. The University of Kentucky also has formalized instruction on design thinking through its dLab. The dLab serves a multitude of functions from helping schools resolve their issues with design thinking to conducting empirical experiments on design thinking to collaborating with outside organizations to provide issues that plague their organization.
In addition to the Stanford University d.school and the University of Kentucky dLab, Radford University, located in Radford, Virginia, currently offers a Masters of Fine Arts (MFA) degree in Design Thinking. The MFA degree offered is a completely online degree that emphasizes design thinking, design history, design research, design management, and design doing.
Obstacles to Implementing Design Thinking in Schools
The accountability to succeed on high-stakes standardized tests in K-12 environments prevents the implementation of design thinking curriculum. Educators feel that focusing on classic curriculum will better prepare their students to perform well on these exams. Resistance to design thinking also springs from concerns about the appropriateness of applying design thinking to an educational setting. It has been argued that design thinking is best applied by professionals who know a field well. Therefore K-12 students who are limited by their reduced understanding of both the field and their still developing intellectual capacities may not be best suited to design thinking activities. Another more subtle obstacle to design thinking in schools may come from members of the academic community who believe design thinking should remain in the milieu of avant-garde companies. Other issues that may prevent the implementation of design thinking in scholastic settings may be a lack of awareness of the field, educators' uncertainty in implementing new approaches to teaching, and lack of institutional support.
Even for institutions that see the value of design thinking, there is the issue of implementing these new approaches to education successfully. Admittedly "creating an effective thinking and successful team learning experience is a sticky wicked problem." 
The integration of ICT into teaching and learning presents many challenges that go beyond issues dealing with technical implementation. Some researchers have already claimed the limited effects of ICT adoption in learning; Considering the emphasis and the investment that has been placed on the use of ICT in formal learning settings (schools and higher education institutions) it is important to identify where are the problems. In this regard, some voices of the educational community focus on the methods used for integrating ICT in teaching and learning;. In this sense, the adoption of a design thinking mindset is regarded as a promising strategy to develop holistic solutions.
Design and Teaching and Learning through ICT can be considered as similar activities. First, it's important to acknowledge that the type of problems faced by the educational community when adopting learning technology are unique, ill-defined and do not have clear solutions;. This definition corresponds very well to the term wicked-problems  used by the design community. Secondly, similarly to what happens in design, the diversity of actors brings another layer of complexity that should be recognized. In this regard, collaboration between different stakeholders during the design process is another key issue that could contribute to develop more meaningful technologies for learning;
Design thinking has been outlined as a meaningful approach for facing wicked problems. The main reason is because the idea that there is a good and unique solution for a problem disappears. The adoption of a design mindset helps understand that there can be many solutions for a given situation and that any design requires testing. From this perspective, bringing design thinking to learning design and design expertise to the development process of technological learning solutions can contribute to the creation of more holistic solutions in learning through ICT 
|pre-1960||The origins of new design methods in the 1960s lay further back in the application of novel, 'scientific' methods to the pressing problems of the 2nd World War from which came operational research methods and management decision-making techniques, and in the development of creativity techniques in the 1950s. Harold van Doren published "Industrial Design - A Practical Guide to Product Design and Development", which includes discussions of design methods and practices, in 1940.|
|1960s||The beginnings of computer programs for problem solving, the so-called soft-systems approach. |
The 1960s marked a desire to "scientize" design through use of the computer science soft-systems approach.
|1962||The First 'Conference on Design Methods,' London, UK. |
Books on methods and theories of design in different fields being to be published: Asimow (1962) (Engineering), Alexander (1964) (Patterns), L. Bruce Archer (1965) (Industrial Design), Jones (1970) (Architecture).
|1965||L. Bruce Archer, professor of Design Research at the Royal College of Art argues that design was "not merely a craft-based skill but should be considered a knowledge-based discipline in its own right, with rigorous methodology and research principles incorporated into the design process" and states; – "The most fundamental challenge to conventional ideas on design has been 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."|
|1969||Herbert A. Simon notable for his research in artificial intelligence and cognitive sciences establishes a "Science of Design" which would be "a body of intellectually tough, analytic, partly formalizable, partly empirical, teachable doctrine about the design process."|
|1970s||Notable for the rejection of design methodology by many, including some of the early pioneers. |
Christopher Alexander, architect and theorist wrote – "I've disassociated myself from the field. There is so little in what is called 'design methods' that has anything useful to say about how to design buildings that I never even read the literature anymore. I would say forget it, forget the whole thing."
John Chris Jones, designer and design thinking theorist stated - "In the 1970s I reacted against design methods. I dislike the machine language, the behaviourism, the continual attempt to fix the whole of life into a logical framework."
|1973||Robert McKim publishes Experiences in Visual Thinking. which includes "Express, Test, Cycle" (ETC) as an iterative backbone for design processes. |
Horst Rittel and Melvin Webber write Dilemmas in a General Theory of Planning showing that design and planning problems are Wicked Problems as opposed to "tame", single disciplinary, problems of science.
Horst Rittel also proposes that the developments of the 1960s had been only 'first generation' methods (which naturally, with hindsight, seemed a bit simplistic, but nonetheless had been a necessary beginning) and that a new second generation was beginning to emerge." This suggestion was clever, because it let the methodologists escape from their commitment to inadequate 'first generation' methods, and it opened a vista of an endless future of generation upon generation of new methods.
|1979||L. Bruce Archer starts off the next decade's inquiry into designerly ways of knowing stating – "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 inquiry when applied to its own kinds of problems."|
|1980s||Systemic engineering design methods are developed, particularly in Germany and Japan. The International Conferences on Engineering Design (ICED) is formed. |
A series of Design Journals begin to be published: Design Studies in 1979, Design Issues appeared in 1984, and Research in Engineering Design in 1989.
Other important developments: Publications of the Design Methods Group and the conferences of the Environmental Design Research Association (EDRA). The National Science Foundation initiative on design theory and methods led to substantial growth in engineering design methods in the late-1980s. The American Society of Mechanical Engineers (ASME) launched its series of conferences on Design Theory and Methodology.
The 1980s also sees the rise of human-centered design and the rise of design-centered business management.
|1980||Bryan Lawson, professor of architecture at University of Sheffield, publishes How Designers Think about design cognition in the context of Architecture and Urban Planning.|
|1982||Nigel Cross, Professor of Design Studies and Editor of Design Studies Journal writes Designerly Ways of Knowing showing Design as its own culture to be taught in schools by contrasting it with Science culture and Arts and Humanities culture. This is based on the idea that "There are things to know, ways of knowing them and ways of finding out about them that are specific to the design area."|
|1983||Donald Schön, professor and theorist in organizational learning, pens his seminal text Educating the Reflective Practitioner in which he 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."|

|1987||Peter Rowe, professor at the Harvard Graduate School of Design, publishes Design Thinking.|
|1988||Rolf Faste, director of the design program at Stanford, creates "Ambidextrous Thinking," a required class for graduate product design majors that extends McKim's process of visual thinking to design as a "whole-body way of doing."|
|1990s||Ideas of organizational learning and creating nimble businesses come to the forefront.|
|1991||IDEO combines from three industrial design companies. They are one of the first design companies to showcase their design process, which draws heavily on the Stanford curriculum.|
|1992||Richard Buchanan's article "Wicked Problems in Design Thinking" is published.|
|2000s||The 2000s brought a significant increase in interest in design thinking as the term becomes popularized in the business press. Books written for the business sector about how to create a more design-focused workplace where innovation can thrive: Florida (2002), Pink (2006), Martin (2007), Gladwell (2008), Brown (2009), Lockwood (2010).|
This shift of design thinking away from the product fields and into the business sector sparks a debate about the hijacking and exploitation of design thinking. According to Bill Moggridge, co-founder of IDEO, in the end of 2000, Lavrans Løvlie, Ben Reason and Chris Downs, joined forces to found live|work, an UK based design consultancy firm which opens up for business on the basis that the design approach should be extended and adapted to tackle the design of services. This marks the beginning of the service design consultancy firms movement worldwide.
