#1 — IDEO

The firm that brought human-centered design into mainstream business practice and has spent three decades proving the methodology works at every scale and in every sector — including some of the most-referenced healthcare design programs in the field. Their Kaiser Permanente work is reference material for what rigorous, research-led healthcare UX looks like when applied across an entire integrated health system. IDEO's ability to operate upstream of a brief — mapping problem spaces before proposing solutions — is particularly valuable in healthcare, where the right question is rarely the one a stakeholder initially asks. When an organization does not yet know what it should be building, IDEO is where you go before you go anywhere else.
