Service Design
Designing the entire experience of a service across every touchpoint and channel — digital and human — not just a single screen or app.
Service design zooms out from a single interface to the whole journey a person takes with an organization — the app, the emails, the support call, the onboarding packet, the in-person moment. It maps how those touchpoints connect and where the experience breaks between them.
It is especially relevant when a product spans channels: a fintech that combines an app, a card, and a call center, or a healthtech that links a patient app to a clinic. A customer journey map is the service designer's core tool.
In practice
A healthtech startup has a polished app but loses patients between “approved” and “first appointment.” Service design maps the whole journey — app, email, clinic front desk, insurance call — and finds the drop: approval emails arrive from an unrecognized sender and the booking link expires in 48 hours. No screen redesign fixes that; the fix spans email sending, link policy, and a front-desk script. Mapping cross-channel handoffs is exactly the work a single-product lens misses.
