Design Thinking is more than thinking and meetings. Design Thinking is about doing and making.
Experimentation is at the core of Design Thinking. Developing prototypes and iterating on ideas is not just to validate your concepts but is an integral part of the innovation process where you build things to think and learn.
When you are developing prototypes there are thousands of decisions that result into more ideas being explores. Even mistakes can be the inspiration for new ideas. More ideas mean more prototypes, iterations, and learning.
It is the doing and making that is the magic of Design Thinking.
