All phases of the Design Thinking process work together to help you: understand the root causes of a problem, get to know the needs and experiences of your users, develop ideas, test aspects of your ideas through prototypes, and test your ideas with your users to gain feedback that you can apply to your work. The resources on this page offer a simplified breakdown of each phase. Keep in mind that many designers use all parts of the Design Thinking process in tandem, looping back and forth between the phases rapidly throughout their work.
Read a fantastic overview article, 5 Stages in the Design Thinking Process from the Interaction Design Foundation.
