Imagine your interviewer asks: “How would you measure the success of Apple’s newly launched iPhone?” Most candidates would say units sold. That matters—but it only measures the purchase, not whether the product created lasting value. First, clarify Apple’s goal: * Attract new customers? * Convince existing users to upgrade? * Grow the premium-phone category? * Increase adoption of a new feature? Then build a complete scorecard: Business metrics * Units sold * Revenue and profit margin * Preorders converted into purchases * Upgrade and Android-switcher rates Customer-value metrics * Devices still actively used after 90 days * Adoption of the headline features * Customer satisfaction * Usage of the wider Apple ecosystem Guardrail metrics * Product returns * Hardware defects and repairs * Battery complaints * App-compatibility issues * Support requests The correct metric depends on the product’s goal. That’s what the interviewer is testing—not whether you memorized a North Star framework. Apple’s latest launch included its new iPhone lineup, making this a timely practice case.
