A Facebook discussion group covering service design, UX, and design thinking as an integrated practice.
Useful specifically for the service-design lens: thinking about a product as one touchpoint in a larger end-to-end customer journey, which is a broader framing than most UI-focused groups take.
Best for designers working on multi-touchpoint or systems-level problems (a whole customer journey, not merely an app), less relevant for purely screen-based UI work.
Service design as a discipline can run abstract: if you want concrete, tactical UI discussion, look elsewhere on this list first.
