Design thinking is a process for solving problems by, empathizing, defining, making an idea, prototype, then testing it. First, you have to find your problem, figure out what's not working in the sichuation. Than, emathise it, make it your focus. Next, define, work on it, try to find a way to fix it. Also, make a idea, brainstorm on how you can or could fix the problem. Once you find that idea, make a prototype. Bild or put that 2D idea and make it come to life. Finally, test it, try it out, see if it could or can work. but its of if it doesn't work on the first time around, you can always circle back to the idea step. Or maybe what you thought was your problem, wasn't really the problem, that's ok too. Design thinking is all about finding the problem and trying to solve it, even if it takes more than one try. All that matters is that you follow the design thinking proses, and keep trying till you find the solution.
