Design Thinking: 5-Step Guide with Singapore Case Studies
Design Thinking is commonly explained through five stages: Empathise, Define, Ideate, Prototype and Test. The value, however, is not in completing five activities in sequence. It is in helping teams understand a problem before committing too quickly to a solution.
Instead of beginning with what an organisation wants to build, Design Thinking starts with the people experiencing the problem, then uses research, experimentation and testing to reduce uncertainty. Singapore organisations across banking, retail and services have applied this approach in very different contexts.
Step 1: Empathise — Understand What People Actually Experience
The first stage involves learning about users through interviews, observation and other forms of research. When Dairy Farm Group developed Jasons Deli at Marina Bay Link Mall, the team faced an unusual challenge: creating a supermarket concept in a much smaller space with limited manpower.
Rather than designing immediately, the team observed shoppers at different times and conducted interviews and focus groups. One useful insight was that the area was not used only by office workers. Families and children also appeared during weekends.
That changed how the team understood who the store needed to serve. Empathy is therefore not simply asking customers what they want. It is understanding the context surrounding their behaviour.
Step 2: Define — Find the Problem Worth Solving
Research often reveals several issues at once. The Define stage helps teams decide which problem deserves attention. Singapore lift company Meyer initially approached its challenge as one of competing against larger international brands. Interviews and observations revealed something deeper: customers were sceptical about the brand and found the process of buying a lift complicated.
The challenge shifted from simply “How do we sell more lifts?” to questions around building trust and making the buying experience easier. That change matters because the way a problem is framed influences the solutions a team will consider.
Step 3: Ideate — Explore More Than One Answer
Once the problem becomes clearer, the team can explore different ways of solving it.
Benjamin Barker experienced this while looking at how to improve training for its Fashion Advisors. Research with staff and observation inside stores showed that the opportunity was larger than simply creating a better training manual.
The team began exploring how the company's wider service culture could be improved through customer-profile cards, visual learning materials, role-play activities and practical training exercises. Good ideation therefore does not mean generating random ideas. The ideas should respond to what the research has uncovered.
Step 4: Prototype — Make the Idea Testable
An idea can sound convincing in a meeting and still fail when someone actually uses it.
Prototyping allows teams to test important assumptions before investing heavily in the final solution. During the development of Jasons Deli, parts of the proposed experience were mocked up using simple materials and tested in existing stores.
This allowed the team to observe how customers responded before the final environment was completed. A prototype does not need to look finished. A digital team might use a clickable wireframe, while a service team could role-play an interaction.
The question is simply: what is the quickest way to make this idea testable?
Step 5: Test — Learn What Should Happen Next
Testing means placing the prototype in front of real users and observing what happens.
The goal is not simply to ask whether they like it. Look at what they understand, where they hesitate and whether the solution actually improves the experience. Jasons Deli continued testing ideas with shoppers, using their reactions to refine elements such as self-service, store zoning and its product range.
DBS has also incorporated human-centred design into its customer journeys, using prototyping and testing to explore concepts before wider implementation. Testing does not necessarily mean the project is finished. Feedback may send the team back to the prototype, the idea or even the original problem definition.
The Five Steps Are Not a Straight Line
Although Design Thinking is usually shown as five stages, real projects are more iterative.
A prototype may reveal something new about users. Testing may show that the team framed the problem incorrectly. New research might create an entirely different solution direction.
A more realistic way to think about the process is:
Understand → Frame → Explore → Make → Test → Learn → Repeat
The goal is not to reach Step 5 as quickly as possible. It is to reduce uncertainty before the cost of changing direction becomes much higher.
How Emerge Creatives Approaches Design Thinking
At Emerge Creatives, Design Thinking is treated as a practical problem-solving process rather than a fixed workshop formula. Research helps challenge assumptions, problem framing determines where the team should focus, ideation creates alternatives, and prototypes make those alternatives easier to test.
The framework provides structure, but the objective remains simple: understand the right problem before investing heavily in the solution.
Conclusion
Design Thinking's five stages are easy to remember:
Empathise → Define → Ideate → Prototype → Test
What matters is how each stage improves the next decision. The Singapore examples from Dairy Farm, Meyer, Benjamin Barker and DBS show the same underlying principle across very different industries: learn from people, clarify the problem, explore alternatives and test ideas before committing too much time or money. Design Thinking does not guarantee the first idea will succeed. It gives teams a more structured way to learn before the cost of being wrong becomes much higher.
