What is Design Thinking?
Design Thinking is an iterative process in which we seek to understand the user, challenge assumptions, and redefine problems in an attempt to identify alternative strategies and solutions that might not be instantly apparent with our initial level of understanding. At the same time, Design Thinking provides a solution-based approach to solving problems. It is a way of thinking and working as well as a collection of hands-on methods.
Design Thinking revolves around a deep interest in developing an understanding of the people for whom we’re designing the products or services. It helps us observe and develop empathy with the target user. Design Thinking helps us in the process of questioning: questioning the problem, questioning the assumptions, and implications. Design Thinking is extremely useful in tackling problems that are ill defined or unknown, by re-framing the problem in human-centric ways, creating many ideas in brainstorming sessions, and adopting a hands-on approach in prototyping and testing. Design Thinking also involves ongoing experimentation: sketching, prototyping, testing, and trying out concepts and ideas.
Design Thinking’s Phases
There are many variants of the Design Thinking process in use today, and they have from three to seven phases, stages, or modes. However, all variants of Design Thinking are very similar. All variants of Design Thinking embody the same principles, which were first described by Nobel Prize laureate Herbert Simon in The Sciences of the Artificial in 1996. Here, we will focus on the five-phase model proposed by the Hasso-Plattner Institute of Design at Stanford, which is also known as d.school. We’ve chosen d.school’s approach because they’re at the forefront of applying and teaching Design Thinking. The five phases of Design Thinking, according to d.school, are as follows:
- Empathise – with your users
- Define – your users’ needs, their problem, and your insights
- Ideate – by challenging assumptions and creating ideas for innovative solutions
- Prototype – to start creating solutions
- Test – solutions
It is important to note that the five phases, stages, or modes are not always sequential. They do not have to follow any specific order and can often occur in parallel and repeat iteratively. As such, you should not understand the phases as a hierarchal or step-by-step process. Instead, you should look at it as an overview of the modes or phases that contribute to an innovative project, rather than sequential steps.
To help you understand Design Thinking, we have broken the process into five phases or modes, which are: 1. Empathise, 2. Define, 3. Ideate, 4. Prototype, and 5. Test. What’s special about Design Thinking is that designers’ work processes can help us systematically extract, teach, learn, and apply these human-centred techniques to solve problems in a creative and innovative way — in our designs, in our businesses, in our countries, in our lives. Nevertheless, a great artist like Auguste Rodin, who created this famous sculpture called “The Thinker” and originally “Le Penseur”, would most likely have used the very same innovative processes during his creative art work. In the same way, all great innovators in literature, art, music, science, engineering, and business have practiced it and still practice it.
The Problem with Ingrained Patterns of Thinking
Sometimes, the easiest way to understand something intangible, such as Design Thinking, is by understanding what it is not.
Humans naturally develop patterns of thinking modelled on the repetitive activities and commonly accessed knowledge. These assist us in quickly applying the same actions and knowledge in similar or familiar situations, but they also have the potential to prevent us from quickly and easily accessing or developing new ways of seeing, understanding, and solving problems. These patterns of thinking are often referred to as schemas, which are organised sets of information and relationships between things, actions, and thoughts that are stimulated and initiated in the human mind when we encounter some environmental stimuli. A single schema can contain a vast amount of information. For example, we have a schema for dogs which encompasses the presence of four legs, fur, sharp teeth, a tail, paws, and a number of other perceptible characteristics. When the environmental stimuli match this schema — even when there is a tenuous link or only a few of the characteristics are present — the same pattern of thought is brought into the mind. As these schemas are stimulated automatically, this can obstruct a more fitting impression of the situation or prevent us from seeing a problem in a way that will enable a new problem-solving strategy. Innovative problem solving is also known as “thinking outside of the box”.
An Example of Problem solving: The Encumbered Vs. The Fresh Mind
Thinking outside of the box can provide an innovative solution to a sticky problem. However, thinking outside of the box can be a real challenge as we naturally develop patterns of thinking that are modelled on the repetitive activities and commonly accessed knowledge we surround ourselves with.
Some years ago, an incident occurred where a truck driver who had tried to pass under a low bridge. But he failed, and the truck was lodged under the bridge. The driver was unable to continue driving through or reverse out.
The story goes that as the truck became stuck, it caused massive traffic problems, which resulted in emergency personnel, engineers, firefighters, and truck drivers gathering to negotiate various solutions to dislodging the truck.
Emergency workers were debating whether to dismantle parts of the truck or chip away at parts of the bridge. Each spoke of a solution which fitted within his or her respective level of expertise.
A boy walking by and witnessing the intense debate looked at the truck, at the bridge, then looked at the road and said nonchalantly, "Why not just let the air out of the tires?" to the absolute amazement of all the specialists and experts trying to unpick the problem.
When the solution was tested, the truck was able to drive free with ease, having suffered only the damage caused by its initial attempt to pass underneath the bridge. The story symbolises the struggles we face where oftentimes the most obvious solutions are the ones hardest to come by because of the self-imposed constraints we work within.

It’s often difficult for us humans to challenge our assumptions and everyday knowledge, because we rely on building patterns of thinking in order to not have to learn everything from scratch every time. We rely on doing everyday processes more or less unconsciously — for example, when we get up in the morning, eat, walk, and read — but also when we assess challenges at work and in our private lives. Especially experts and specialists rely on their solid thought patterns, and it can be very challenging and difficult for experts to start questioning their knowledge.
The Power of Storytelling
Why did we tell you this story? Telling stories can help us inspire opportunities, ideas, and solutions. Stories are framed around real people and their lives. Stories are important because they are accounts of specific events, not general statements. They provide us with concrete details that help us imagine solutions to particular problems. While we’re at it, please watch this 1-minute video to help you get started understanding what Design Thinking is about.
Design Thinking is often referred to as ‘outside the box’ thinking. This child shows us what why it’s important to challenge our assumptions and find new ways to solve our problems.
Design Thinking or 'Outside the Box' Thinking
Design Thinking is often referred to as ‘outside the box’ thinking, as designers are attempting to develop new ways of thinking that do not abide by the dominant or more common problem-solving methods.
At the heart of Design Thinking is the intention to improve products by analysing and understanding how users interact with products and investigating the conditions in which they operate. At the heart of Design Thinking lies also the interest and ability to ask significant questions and challenging assumptions. One element of outside the box thinking is to falsify previous assumptions, i.e., make it possible to prove whether they are valid or not. Once we have questioned and investigated the conditions of a problem, the solution-generation process will help us produce ideas that reflect the genuine constraints and facets of that particular problem. Design Thinking offers us a means of digging that bit deeper; it helps us do the right kind of research and to prototype and test our products and services so as to uncover new ways of improving the product, service, or design.
Grand Old Man of User Experience, Don Norman, who also coined the very term User Experience, explains what Design Thinking is and what’s so special about it:
“…the more I pondered the nature of design and reflected on my recent encounters with engineers, business people and others who blindly solved the problems they thought they were facing without question or further study, I realized that these people could benefit from a good dose of design thinking. Designers have developed a number of techniques to avoid being captured by too facile a solution. They take the original problem as a suggestion, not as a final statement, then think broadly about what the real issues underlying this problem statement might really be (for example by using the "Five Whys" approach to get at root causes). Most important of all, is that the process is iterative and expansive. Designers resist the temptation to jump immediately to a solution to the stated problem. Instead, they first spend time determining what the basic, fundamental (root) issue is that needs to be addressed. They don't try to search for a solution until they have determined the real problem, and even then, instead of solving that problem, they stop to consider a wide range of potential solutions. Only then will they finally converge upon their proposal. This process is called "Design Thinking."

Design Thinking is an Essential Tool – and A Third Way
The design process often involves a number of different groups of people in different departments; for this reason, developing, categorising, and organising ideas and problem solutions can be difficult. One way of keeping a design project on track and organising the core ideas is with a Design Thinking approach.
Tim Brown, CEO of the celebrated innovation and design firm IDEO, shows in his successful book, Change by Design that Design Thinking is firmly based on generating a holistic and emphatic understanding of the problems that people face, and that it involves ambiguous or inherently subjective concepts such as emotions, needs, motivations, and drivers of behaviours. This contrasts with a solely scientific approach, where there’s more of a distance in the process of understanding and testing the user’s needs and emotions — e.g., via quantitative research. Tim Brown sums up that Design Thinking is a third way: Design Thinking is essentially a problem-solving approach, crystalized in the field of design, which combines a holistic user-centred perspective with rational and analytical research with the goal of creating innovative solutions.
“Design thinking taps into capacities we all have but that are overlooked by more conventional problem-solving practices. It is not only human-centered; it is deeply human in and of itself. Design thinking relies on our ability to be intuitive, to recognize patterns, to construct ideas that have emotional meaning as well as functionality, to express ourselves in media other than words or symbols. Nobody wants to run a business based on feeling, intuition, and inspiration, but an overreliance on the rational and the analytical can be just as dangerous. The integrated approach at the core of the design process suggests a ‘third way.’“
– Tim Brown, Change by Design, Introduction
Science and Rationality in Design Thinking
Some of the scientific activities will include analysing how users interact with products and investigating the conditions in which they operate: researching user needs, pooling experience from previous projects, considering present and future conditions specific to the product, testing the parameters of the problem, and testing the practical application of alternative problem solutions. Unlike a solely scientific approach, where the majority of known qualities, characteristics, etc. of the problem are tested so as to arrive at a problem solution, Design Thinking investigations include ambiguous elements of the problem to reveal previously unknown parameters and uncover alternative strategies.
After arriving at a number of potential problem solutions, the selection process is underpinned by rationality. Designers are encouraged to analyse and falsify these problem solutions so that they can arrive at the best available option for each problem or obstacle identified during each phase of the design process.
With this in mind, it may be more correct to say that Design Thinking is not about thinking out of the box, but on its edge, its corner, its flap, and under its bar code, as Clint Runge put it.

Generating Creative Ideas and Solutions by Holistically Understanding Humans
With a solid foundation in science and rationality, Design Thinking seeks to generate a holistic and emphatic understanding of the problems that people face. Design thinking tries to empathise with human beings. That involves ambiguous or inherently subjective concepts such as emotions, needs, motivations, and drivers of behaviours. The nature of generating ideas and solutions in Design Thinking means this approach is typically more sensitive to and interested in the context in which users operate and the problems and obstacles they might face when interacting with a product. The creative element of Design Thinking is found in the methods used to generate problem solutions and insights into the practices, actions, and thoughts of real users.
Design Thinking is an Iterative and Non-linear Process

Design Thinking is an iterative and non-linear process. This simply means that the design team continuously use their results to review, question, and improve their initial assumptions, understandings and results. Results from the final stage of the initial work process inform our understanding of the problem, help us determine the parameters of the problem, enable us to redefine the problem, and, perhaps most importantly, provide us with new insights so we can see any alternative solutions that might not have been available with our previous level understanding.
Design Thinking is for Everybody
Tim Brown also empathises that Design Thinking techniques and strategies of design belong at every level of businesses. Design thinking is not only for designers, but also for creative employees, freelancers, and leaders who seek to infuse design thinking into every level of an organization, product, or service in order to drive new alternatives for business and society.
“Design thinking begins with skills designers have learned over many decades in their quest to match human needs with available technical resources within the practical constraints of business. By integrating what is desirable from a human point of view with what is technologically feasible and economically viable, designers have been able to create the products we enjoy today. Design thinking takes the next step, which is to put these tools into the hands of people who may have never thought of themselves as designers and apply them to a vastly greater range of problems.”

The Take Away
Design Thinking is essentially a problem-solving approach specific to design, which involves assessing known aspects of a problem and identifying the more ambiguous or peripheral factors that contribute to the conditions of a problem. This contrasts with a more scientific approach where the concrete and known aspects are tested in order to arrive at a solution. Design Thinking is an iterative process in which knowledge is constantly being questioned and acquired so it can help us redefine a problem in an attempt to identify alternative strategies and solutions that might not be instantly apparent with our initial level of understanding. Design Thinking is often referred to as ‘outside the box thinking’, as designers are attempting to develop new ways of thinking that do not abide by the dominant or more common problem-solving methods – just like artists do. At the heart of Design Thinking is the intention to improve products by analysing how users interact with products and investigating the conditions in which they operate. Design Thinking offers us a means of digging that bit deeper to uncover ways of improving user experiences.
“The ‘Design Thinking’ label is not a myth. It is a description of the application of well-tried design process to new challenges and opportunities, used by people from both design and non-design backgrounds. I welcome the recognition of the term and hope that its use continues to expand and be more universally understood, so that eventually every leader knows how to use design and design thinking for innovation and better results.”
