What does it mean to experience healthcare? More often than not, the experience is more than a device, more than a piece of software, more than a caregiver, more than a place. Healthcare is most frequently experienced as a combination of people, environments, tools, and technology – in other words, a service. For a healthcare services to be successful, we need to do two things: take a holistic design approach, and design for changing needs over time. This is especially true when designing for behavior change – an increasingly common goal in healthcare – because people’s needs change as their situation evolves.
