Your question is Designing With Incomplete Information. 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 make an important design decision with limited information — for example, unclear user needs, incomplete research, or conflicting stakeholder input. How did you decide what to ship, and what happened afterward?
