Your question is Success Metrics for New Features. 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).
Give me 5 metrics you would track for measuring a success of a new feature within the app.
Focus on metrics that show adoption, engagement, conversion, retention, and guardrails. Be ready to explain how each metric would be defined, why it is useful, and how you would tell whether the feature helped or hurt the product.
