Because I left as the new team arrived, none of these decisions were validated by user testing before my departure — that was, by design, the next team's job. So I can't point to a movement in support-call volume and claim it as mine. What I can point to is the handoff: a diagnosis of the real problem, worked-through concepts, use cases and requirements from actual clients, cross-platform teams organized, and a test plan ready to validate it all. For a company that had never had UX, that was the difference between starting cold and starting with momentum. The takeaway is about scope and voice: when you don't have the time, tools, or research to do the job fully, the responsible move is to say so, out loud, early.
