Your question is Owning an Ambiguous Production Issue. 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 were given a vague or incomplete problem in production and had to take ownership to drive it to resolution. How did you decide what to do first, who did you involve, and what was the outcome?
