Your question is Defining Pre-Design Success Metrics. 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 how you define success metrics for a digital product before you begin designing.
Explain how you would connect product goals to user and business outcomes, select leading and lagging indicators, establish baselines, and use metrics to guide design decisions. Describe how you would handle competing stakeholder priorities and validate that the metrics measure meaningful value rather than superficial activity.
