Design thinking is a human-centred approach to problem-solving that helps people understand users, question assumptions and develop solutions through experimentation. Rather than jumping straight to an answer, teams explore the problem from the user’s perspective, generate different possibilities and test ideas before committing significant resources.
This approach remains relevant as workplaces navigate rapid technological and organisational change. A 2026 systematic review examining design thinking in organisational change found that it can help organisations navigate complex transformation by encouraging participation, experimentation and iterative learning. This is particularly valuable as organisations respond to evolving customer expectations, technologies and ways of working.
Beyond traditional design roles, these capabilities can support professionals navigating the digital economy, building transferable skills and pursuing long-term career development. This article explores what design thinking is, why it matters, common frameworks, its five stages, Singapore case studies and practical ways to develop your skills.
What Is Design Thinking?
Design thinking is an iterative problem-solving approach that places people and their needs at the centre of the process. It combines research, creativity, experimentation and feedback to help teams better understand problems and develop solutions that are desirable for users and practical to implement.
It can be applied beyond product design, including services, internal processes, business strategies and customer experience. While different organisations use different frameworks, design thinking generally reflects three core mindsets:
- Human-centred: Start by understanding the people affected by a problem, including their needs, behaviours, motivations and frustrations
- Iterative: Treat solutions as ideas to be tested and improved rather than expecting to find the perfect answer immediately
- Collaborative: Bring together people with different perspectives and expertise to challenge assumptions and develop stronger ideas
IDEO describes design thinking as both mindsets and design-based activities that enable collaborative, human-centred problem-solving.
Why Is Design Thinking Important?
Design thinking gives organisations a structured yet flexible way to understand complex problems, explore new possibilities and develop solutions around genuine human needs.
Helps Uncover the Right Problems
Teams can investigate users’ experiences before defining a problem. Interviews, observations and journey mapping may reveal that the underlying issue differs considerably from what the organisation initially assumed.
Encourages Innovation and Creativity
Rather than settling on the first workable answer, design thinking encourages teams to generate multiple possibilities. This creates space for unconventional ideas and can lead to more innovative products, services and processes.
Reduces the Risk of Costly Mistakes
Prototypes allow teams to test assumptions before committing extensive time or resources. Early feedback can expose usability problems, unmet needs or impractical features while changes remain relatively inexpensive.
Strengthens Cross-functional Collaboration
Design thinking brings together different departments and disciplines around a shared problem. Employees combine technical skills with soft skills such as empathy, communication and teamwork to develop more rounded solutions.
Creates More User-centred Experiences
By studying what people actually need, organisations can improve how customers and employees interact with products, services and processes. For an online business, this might involve simplifying a confusing checkout journey.
Builds Adaptability and Problem-solving Capabilities
Design thinking encourages experimentation, curiosity and learning from feedback. These capabilities can help professionals respond to changing responsibilities, emerging in-demand jobs or career disruption following events such as retrenchment.
3 Design Thinking Frameworks
Design thinking frameworks organise human-centred problem-solving into practical stages or activities. Teams can choose and adapt a framework according to the challenge, organisation and people involved.
1. Stanford d.school Five-Stage Design Thinking Framework
The Hasso Plattner Institute of Design at Stanford University, commonly known as the d.school, popularised a five-mode model comprising Empathise, Define, Ideate, Prototype and Test. The d.school emphasises that these are modes rather than a rigid sequence.
- Empathise: Research users to understand their experiences, behaviours and needs
- Define: Synthesise research findings into a clear and meaningful problem statement
- Ideate: Explore numerous possible approaches to the defined problem
- Prototype: Turn promising ideas into simple, tangible versions that people can experience
- Test: Gather user feedback and use what you learn to refine the solution or reconsider earlier assumptions
This framework is one of the most widely recognised models of design thinking and is explored in greater detail in the next section.
2. Design Council Double Diamond
The UK Design Council developed the Double Diamond in the early 2000s as a visual way to describe the design and innovation process. It represents alternating periods of divergent thinking, where possibilities expand, and convergent thinking, where teams narrow their focus.
- Discover: Research the challenge broadly and understand the people affected by it
- Define: Analyse insights to identify and clearly articulate the problem that needs solving
- Develop: Generate, prototype and refine different potential solutions
- Deliver: Test promising solutions, improve them and prepare the selected approach for implementation
The framework is particularly useful for illustrating that teams should first explore the problem widely before narrowing it, then expand their solution options before selecting what to deliver.
3. IBM Enterprise Design Thinking
IBM developed Enterprise Design Thinking to apply human-centred design at the speed and scale required by large organisations. Its framework combines a continuous cycle of observing, reflecting and making with three "Keys" that help teams stay aligned.
- Hills: Define meaningful user outcomes that give teams a clear direction without prescribing a particular solution
- Playbacks: Bring teams, users and stakeholders together regularly to share progress, exchange feedback and identify misalignment
- Sponsor users: Involve real users throughout development so that teams remain connected to genuine needs and experiences
This model can be particularly useful for large, multidisciplinary teams where stakeholder alignment is as important as generating ideas.
5 Stages of Design Thinking
The five-stage Stanford d.school model is one of the most popular ways to understand design thinking. However, the stages are not strictly linear. Teams can revisit earlier stages as new insights emerge.
Stage 1: Empathise
Learn directly from users through interviews, observations, conversations and other research methods. The objective is to understand their experiences and needs rather than approaching the challenge based solely on assumptions.
Stage 2: Define
Organise and interpret your research to identify patterns and underlying needs. Translate these insights into a focused problem statement that gives the team a meaningful challenge to address.
Stage 3: Ideate
Generate a broad range of possible solutions without judging ideas too quickly. Techniques such as brainstorming, mind mapping and "How might we" questions can encourage teams to explore different directions.
Stage 4: Prototype
Turn selected ideas into simple representations that can be explored and tested. Depending on the solution, prototypes could include sketches, storyboards, mock-ups, role-playing exercises or basic digital interfaces.
Stage 5: Test
Put prototypes in front of intended users and observe their reactions. Gather feedback to identify what works, what needs improvement and whether findings require you to revisit earlier stages.
Case Studies of Design Thinking in Singapore
Design thinking has been applied by organisations across Singapore to improve visitor experiences, public services and workplace practices. These examples demonstrate how human-centred research can translate into practical outcomes.
Mandai Wildlife Reserves: Engaging Children Beyond Zoo Visits
Mandai used interviews, observations and prototypes to understand families before developing My Animal Buddy, extending children's engagement with wildlife beyond zoo visits. Among participating families, 80% activated an account and visited the website.
IRAS: Making Tax Easier for SMEs
IRAS researched SME needs through in-depth and guerrilla interviews, then co-created solutions to simplify tax interactions. The design thinking initiative ultimately produced an award-winning digital onboarding tool for new SMEs.
HP Singapore: Using Design Thinking to Transform Workplace Culture
HP Singapore uses design thinking-inspired culture sprints to gather, prototype and test employee ideas. The approach has supported initiatives including skills-based hiring and iterative improvements to its candidate experience and recruitment processes.
How Can I Get Started With Design Thinking?
You do not need to be a professional designer to practise design thinking. Start by developing habits that strengthen empathy, experimentation, collaboration and your ability to learn from users.
Practise Observing and Listening To Users
Look for opportunities to speak with people who experience a problem directly. This could include customers, colleagues, friends or people in your professional network. Ask open-ended questions, observe how they approach a task and pay attention to recurring frustrations, workarounds or unmet needs.
Turn Problems into "How Might We" Questions
Practise reframing complaints or challenges as opportunities. Instead of asking why customers abandon a process, for example, ask: "How might we make this process easier and more reassuring for customers?"
Prototype Ideas Quickly
Turn an idea into a simple version and test it before investing heavily. For example, testing a redesigned online form might reveal that users misunderstand an instruction or cannot find the next button, issues that may not have been obvious during planning.
Work with People Who Think Differently
Collaborate with colleagues from different functions, backgrounds and learning styles. Diverse perspectives can challenge assumptions while helping you develop collaboration, facilitation and other useful leadership qualities.
Build Your Skills Through Design Thinking Courses
Structured training can help you understand established frameworks and practise them with guidance. This can complement other professional capabilities, including personal branding, by helping you demonstrate a practical approach to innovation and problem-solving.

Build Better Solutions With Design Thinking
Design thinking offers more than a set of steps. It provides a way to approach uncertainty with curiosity, empathy and experimentation. By understanding people before designing solutions, exploring multiple ideas and learning through prototypes, professionals can tackle workplace challenges with greater confidence. Its applications span products, services, processes and organisational transformation, making it valuable across industries and roles.
FAQs About Design Thinking
"How might we" reframes a problem as an opportunity for ideas. The question encourages teams to explore multiple possible solutions without assuming that there is only one correct answer.
Design thinking has no single inventor. Its development drew from design and engineering practices, while IDEO and Stanford d.school later played significant roles in popularising its methods.
Design thinking focuses on understanding users and developing desirable solutions. Lean startup focuses on testing business assumptions through build-measure-learn cycles. The two approaches can therefore complement each other.
Anyone can use design thinking. Managers, marketers, entrepreneurs, engineers, public officers and other professionals can apply it to solve problems involving products, services, processes or workplace experiences.
