Design thinking is a dynamic methodology used by teams to understand user needs, challenge assumptions, redefine problems, and create innovative solutions through prototyping and testing. It fosters innovation and is particularly effective for addressing ambiguous issues and consists of five phases: Empathize, Define, Ideate, Prototype, and Test. By embracing design thinking and system design principles, designers can transcend conventional approaches and chart a course towards a more equitable, resilient, and sustainable transportation future.
