What is design thinking?

Design thinking is a human-centric design methodology first mentioned in 1969 by cognitive scientist and Nobel Prize laureate Herbert A. Simon. But, the idea didn’t stop there. Design thinking has only continued to develop with the exponential growth of the tech industry.

Design thinking is now considered a key concept in user-centered design. That being said, an understanding of the approach is fundamental for people looking to get started as UX/UI Designers.

To expand, design thinking is an approach to problem-solving that focuses on innovation and creation. UX/UI Designers use the design thinking process to discover problems and come up with creative solutions by thoroughly understanding their users’ goals, frustrations, and end-task.

Goals of design thinking 

Their goal is to design products that are easy to use, rather than expecting users to adapt to said products.

As the world becomes increasingly complex, many organizations have successfully implemented design thinking to find solutions for little-known problems. (That is, problems we didn’t even know we had!)

Take Amazon or Airbnb, for example. Amazon, in particular, has revolutionized the way we shop. The platform is easy to use and adds value by making shopping fast and fun. Design teams for companies such as these identify and reframe everyday “problems” in ways that focus on what is ultimately important for users.

For example, let’s consider the everyday vegetable peeler. What was once a metal peeler with a metal handle, Sam Farber’s wife spoke up that the peeler was quite uncomfortable on her arthritic hands. Sam set out to make a more comfortable peeler. But first he needed to focus on the user’s needs to understand what was hurting and how.

Sam made many revisions such as a wider handle and a softer material (rubber) that would also provide a more stable grip. All of the revisions he made were an improvement for his wife who had arthritis, but also proved helpful for people without arthritis.

Why? Because the product was easier and more comfortable to use overall. 

This is design thinking in action. 

Design thinking in UX/UI design

Especially important in user experience (UX) design, design thinking helps to address changes in users’ environments and behaviors that may not be immediately apparent. This is good news for both users and the company bottom line, as designers are continuously researching, testing, and improving products.

UX designers put themselves in the user’s shoes, becoming empathetic to their desires and grievances. They also follow a set of hands-on steps (often used interchangeably with phases and stages). Ultimately, using design thinking allows UX teams to do better research, prototyping, and usability testing to address human needs in the modern age.

5 stages of design thinking

The five phases of design thinking:

  1. Empathize
  2. Define
  3. Ideation
  4. Prototype
  5. Test

However, design thinking is a non-linear process. This means that designers can re-visit each phase in an iterative way. That is, they continuously re-examine the product and processes to understand users, challenge assumptions, redefine problems, and create innovative solutions. Since product design teams are prolific in their approach, creativity and problem-solving are valuable skills for both UX and UI designers.

The importance of feedback in design thinking

Feedback is also critical in the design process. According to Oxford Languages, feedback is, “information about reactions to a product, a person’s performance of a task, etc. which is used as a basis for improvement.”

Design teams utilize user feedback to come up with improved versions of their ideas or products. However, the feedback isn’t static. Rather, it’s cyclical. Therefore, design teams may establish feedback loops in order to maximize user feedback.

In feedback loops, design teams quickly build, measure, and learn from users in an cyclical fashion. They continuously tweak their products and ideas until the best possible outcome is reached.

In order to obtain feedback during usability testing, teams may:

  • Administer anonymous surveys
  • Observe user’s during testing
  • Ask open ended questions during interviews
  • Announce ideas in a public forum and monitor response

There is also room for experimentation in the design process. Design Thinking for Public Policy Innovators puts it this way, “By embracing experimentation we push ourselves to stay experimental, to build to think, to engage people with artifacts, and to elicit and receive feedback in a way that will help us learn more about both our designs and about design thinking.”

Throughout the feedback process, it’s essential to focus on the average user rather than the extreme of either end of the spectrum. It’s simply not necessary to spend time and energy on perceived issues that may only affect the user’s perspective incrementally. Instead, it’s more productive to focus only on collecting and using feedback that will change the core user experience to a greater degree.

The five stages of the design thinking process

Design thinking is a five-stage process as defined by the Hasso-Plattner-Institute of Design and based on the original method developed at Stanford (also known as d.school). The stages are flexible and do not always need to be followed in order. Teams may run them in parallel or out of order and re-visit stages as needed in the iterative process.

stage 1 empathy

Stage 1: Empathy — understand the needs of people

The first stage of the design thinking process is to gain an empathic understanding of the problem you are trying to solve. Understanding the human point of view is crucial.

This is when designers go into detective mode to get to know the user and understand their desires, needs, and objectives when interacting with a product or service.

This detective-designer will come to understand the “problem space,” or what is currently hindering the completion of the task. This looks like conducting user research by observing people and/or asking questions.

During this phase, designers set aside their own beliefs and assumptions.

Instead, they get into the mind of the user on an emotional and psychological level to come up with actionable insights. And then use insights from stage one to inform the remaining stages.

user need statements

Stage 2: Define — state the user’s needs and problems

Next, the designer must clearly define the user’s needs and problems. They begin by making sense of the data and observations gathered during stage one, for example:

  • What patterns do they see?
  • What did they hear most often?
  • What difficulties did the users have?

This is also the stage in which designers create user personas to remind them to keep the discussion on the end-user. Once the team has identified core issues with the product or service, they formulate a problem statement. The problem statement should remain user-centric. For example, “Millenials in NYC will…” rather than, “Our team will….”

Once designers have put the problem into words, they start to come up with solutions and ideas. It’s now time for stage three.

Stage 3: Ideation phase — come up with innovative ideas

stage 3 design thinking

Here comes the fun part! Design teams get to be wildly creative when problem-solving in the third stage — ideation. With an understanding of the end-user and a clear problem statement, designers hold collaborative ideation sessions and use ideation techniques. Brainstorm, Worst Possible Idea, and SCAMPER are all ideation techniques that designers use to come up with possible solutions.

The goal of an ideation session is to look at the problem from all angles and generate as many ideas as possible. 

For example, the “Worst Possible Idea” ideation technique works as a great icebreaker, putting teams at ease as they come up with the worst ideas and then seek alternatives.

Brainstorming leverages the collective thinking of the team, generating many more ideas than an individual writing his or her own list.


Lastly, teams can take an existing product, service, or idea and go through the SCAMPER list (Substitute, Combine, Adapt, Modify, Put to another use, Eliminate, Reverse) in order to improve it. To start practicing this skill, begin Freewriting regularly — setting a timer and letting your ideas flow uninterrupted and without judgement — and then going back to pull out the best ideas.

At the end of the ideation stage, the best ideas will move forward to the next phase, prototyping.

Stage 4: Prototype — start creating solutions

The next step in the design thinking process is prototyping. It’s about taking all the ideas from stage three and creating tangible products to experiment with. With the concept fleshed out, UX designers are now able to produce several inexpensive, scaled-down versions of the product or specific features found within the product.

This is important because it allows designers to test and validate their ideas quickly and cheaply. It also may bring forth additional iterations of the product’s initial concept before final execution, avoiding costly mistakes.

Prototypes can take many forms — low-tech sketches, storyboards, and rough paper prototypes to mocked up, coded apps on the high end.

With the high or low-fidelity prototypes, it’s time to investigate and run experiments to see if the solutions generated in the previous stages function. Although a designer may personally like one prototype the best, this phase aims to identify the best possible solution for each of the problem statements, always keeping the end-user in mind. It’s essential that teams work together to test and highlight any flaws, and accept, improve, or reject the ideas based on data.

Once you’ve agreed on the best prototype, you are ready to test your product in the last stage.

Stage 5: Test — try out solutions

test phase design thinking

In the last stage, evaluators rigorously test the complete product. Although this is the last stage in the design thinking process, it’s not likely the end. The results either confirm or challenge the solutions from a previous stage. Since design thinking is iterative, designers examine the results and head back to previous steps, constantly making changes, refining, and improving.

Remember, these hands-on steps are not necessarily sequential, and teams may revisit them as needed. The main goal throughout is to gain a deeper understanding of the users and what their ideal product would look like.
