Your question is Turn Stakeholder Needs Into Specs. 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).
How do you break down a vague business problem from a stakeholder into concrete data requirements and technical pipeline specifications?
Explain how you clarify the desired outcome, identify the necessary entities and metrics, validate assumptions, and translate the result into an implementable pipeline design. Be specific about how you handle conflicting definitions, incomplete source data, changing priorities, and stakeholder disagreement. Focus on a real example and describe your actions, decisions, and measurable result.
