Design thinking is a human-centered approach to solving problems. It starts with empathy for the people who will use the solution. It moves through defined stages: empathize, define, ideate, prototype, and test. The process is iterative. Prototypes reveal what works and what does not. The team loops back to earlier stages as they learn. The goal is not a perfect solution on the first try. It is a solution that fits real needs, discovered through experimentation.

The approach came from IDEO and the Stanford d.school. It spread beyond product design into business, education, healthcare, and government. The appeal is the structure. It gives teams a shared language for tackling ambiguous problems. It encourages divergent thinking before convergent thinking. Generate many options before choosing one. It also values prototyping. A rough prototype in a day teaches more than a month of debate. Design thinking has critics. Some say it oversimplifies complex problems. Others say it is just good design practice with a new name. Both critiques have merit. The process is not magic. It works when the team has the skills to execute and the authority to act on what they learn. It fails when it becomes a checkbox exercise. The method is only as good as the people using it.

Design thinking stages

1. Empathize — understand the user's experience
2. Define — frame the problem clearly
3. Ideate — generate many possible solutions
4. Prototype — build rough versions to test
5. Test — learn from real users and iterate

Design thinking is a process, not a destination. The learning happens in the loop.
