Address it immediately but diplomatically. Establish clear processes for feature commitments, involve product in customer conversations, and create a feedback loop from sales to product.

Define north star metrics (engagement, retention), supporting metrics (creation rate, completion rate), and guardrail metrics (content quality, user satisfaction). Explain the hierarchy and how they relate.

Cover adoption metrics (activation, usage), engagement metrics (frequency, depth), business metrics (revenue impact), and quality metrics (errors, performance). Explain leading vs lagging indicators.

Define success criteria upfront (SMART goals). Discuss product-market fit indicators, customer satisfaction scores, retention curves, and unit economics. Show how metrics evolve over product lifecycle.

Show analytical thinking by investigating data quality, segmenting users, and understanding context. Demonstrate how you formed hypotheses and ran experiments to clarify.
