"Design thinking refers to the cognitive, strategic and practical processes by which design concepts (proposals for new products, buildings, machines, etc.) are developed. Many of the key concepts and aspects of design thinking have been identified through studies, across different design domains, of design cognition and design activity in both laboratory and natural contexts."

"At the same time, Design Thinking provides a solution-based approach to solving problems. It is a way of thinking and working as well as a collection of hands-on methods."

In my eyes design thinking uses the five stages of design thinking to identify the problem find how you want to solve it brainstorm how you will make it happen make a simulation of the problem make sure it will help to solve the issue then use it to solve the issue
