Design Thinking

The above graphic is recreated based on one available on the Norman Nielsen Website. Here you can see six instead of five phases.

The Design Thinking Process

Design thinking is a human-centered approach to problem-solving that has become integral to innovation across industries. It offers a framework for addressing complex challenges by focusing on the needs of people, the feasibility of technology, and business viability. Originating from the field of design, this methodology has evolved into a powerful tool for businesses, educators, and organizations around the world.

The Origins of Design Thinking

Originated in 1960s when industrial designers and engineers began discussing "wicked problems"—issues that are difficult or impossible to solve due to incomplete, contradictory, or changing requirements. Horst Rittel and Melvin Webber argued that traditional problem-solving approaches were inadequate for dealing with complex societal issues. This is where design thinking was born.

Evolution of Design Thinking

In the late 1980s and 1990s, design firms like IDEO started formalizing design thinking. They helped popularize the process as an approach to tackle not just product design but also service design and organizational change.

According to Tim Brown, design thinking bridges the gap between desirability (human needs), feasibility (technology), and viability (business)​

Today, the design thinking process is widely recognized for its five core phases: Empathize, Define, Ideate, Prototype, and Test. These steps are not always sequential and often overlap in an iterative loop.

Empathize

The first phase of design thinking focuses on understanding the needs, wants, and emotions of the users you’re designing for. This involves direct observation, user interviews, and other techniques to gain deep insights.

Activities
  • User Interviews
  • Ethnographic research
  • Shadowing
Tools
  • Empathy maps
  • User journey maps
Output:

A clear understanding of user pain points, motivations, and needs.

Define

In this phase, the insights gathered from the Empathize stage are synthesized into a clear problem statement. Designers seek to define a specific, actionable problem that can guide the ideation process.

Activities
  • Affinity diagramming
  • Problem statement creation
Tools
  • Persona creation
  • Problem framing templates
Output:

A clear problem statement or "How might we" question.

Ideate

The ideation phase is where brainstorming and creativity take center stage. The goal is to generate as many ideas as possible before refining and selecting the most promising ones.

Activities
  • Brainstorming
  • Mind mapping
Tools
  • SCAMPER technique (Substitute, Combine, Adapt, Modify, Put to another use, Eliminate, Reverse)
Output:

A wide range of potential solutions or concepts

Prototype

Prototyping involves creating low-fidelity models of your ideas. These could be sketches, mockups, or digital simulations that allow users to interact with the concept.

Activities
  • Wireframing
  • 3D modeling
Tools
  • Figma
  • Adobe XD
Output:

Initial prototypes that are ready for testing.

Test

The final phase involves testing prototypes with real users to gather feedback and refine the solution. This step is often cyclical, feeding back into the earlier phases as the design evolves.

Activities
  • Usability testing
  • A/B testing
Tools
  • User feedback forms
  • Analytics tools like Hotjar or Google Analytics
Output:

Refined product based on user feedback.
