As asked
Leadership wants a single active user number to track. How would you define it, and how would you defend that definition?
Sample answer outline
Start from what value the product delivers and pick an action that signals a user got that value, rather than a trivial app open. Choose a sensible window, daily, weekly, or monthly, based on the natural usage frequency. Defend it by showing how it correlates with retention and revenue, naming what it deliberately excludes, and explaining why a stricter or looser definition would mislead. Be ready to evolve it as the product changes.
