Design Thinking is a structured innovation approach that consistently starts from the human perspective. Rather than developing solutions at a desk, teams move through five phases — Empathize, Define, Ideate, Prototype, Test — which are iterative, not linear. The approach is particularly suited for problems where neither the problem nor the solution is clearly defined.
In practice, this means: a hospital team that wants to improve the patient experience does not start with process optimization but spends a day in the patient’s role. From this observation emerge insights that no whiteboard workshop could deliver. Ideas are built as rapid prototypes and immediately tested with real users — not after months, but after days.
Design Thinking was developed in the 1990s at the Stanford d.school under David Kelley and spread globally through the design firm IDEO. The guiding principle is to fail early and often: every failed prototype yields knowledge that makes the next attempt better. The approach only works when teams are willing to rigorously question their own assumptions.
