What are the five stages?
1) Empathize: interview and observe users to understand behavior and feelings. 2) Define: frame insights as a "How might we…?" question. 3) Ideate: generate lots of ideas without judging. 4) Prototype: build cheap, quick versions—paper sketches, mockups. 5) Test: watch users react and loop back. It's iterative, not a one-pass checklist.
Where is it used, and what are its limits?
It's used to redesign hospital waiting rooms, run project-based classes, shape public services, and plan startup products. Pairing it with personas and lean startup MVP experiments works well. Critics warn of "design thinking theater": sticky-note workshops that never turn into shipped change.
