Your question is Validating Design With Sparse Signals. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Tell me about a time you had to validate an important design decision when user research was limited, fragmented, or unavailable. How did you reduce uncertainty, make the call, and build confidence with stakeholders afterward?
