The Design Thinking Process
- Definition
A human-centered, iterative framework for solving problems by understanding people’s needs before proposing solutions. Its most common form runs through five stages — Empathize, Define, Ideate, Prototype, and Test — worked through in sequence but revisited freely rather than marched through once.

It keeps the work anchored to a real person’s need instead of the designer’s first idea. Jumping straight to a solution is the default failure; the process exists to hold that impulse off long enough to understand the problem it is meant to solve.

It’s easy to read the five stages as a checklist to complete once, top to bottom. The stages are non-linear: a test that fails sends you back to Define, or even Empathize, and that return is the method working rather than a setback. Picture it as a loop with arrows running backward, not a staircase.
