Comparing Facebook App Health Between Two Countries With Normalized Metrics

You are a product manager at Meta. You are asked to analyze how Facebook is performing in one country, call it X, compared with another country, Y. Explain how you would structure that comparison, which measures you would rely on, and how you would reach a conclusion about where Facebook is doing better and why. ```hint Raw totals mislead The two countries can differ in population, internet access, device mix and how long Facebook has been established there. Before comparing any number, decide what it should be measured against. ``` ### Clarifying Questions - Does "Facebook" mean only the core Facebook app, or the whole family of apps, including Instagram, WhatsApp and Messenger? - What decision should the comparison inform: where to invest next, why one market is lagging, or a routine health review? - Is Facebook at a similar stage in both countries, or is it mature in one and still growing quickly in the other? - Should the answer be a snapshot of the current state, or a trend over a period such as the last year? ### What a Strong Answer Covers - A definition of "performance" tied to Facebook's goals, with a clear headline metric for user value and one for business value instead of a long undifferentiated list. - Normalization for market differences: share of the addressable online population, per-user rates, lifecycle stage and local ad prices, so the two countries are compared fairly. - Coverage of the main areas (reach and growth, engagement depth, retention, monetization, app quality on local networks and devices, account integrity). - Segment cuts such as age, new versus tenured users and platform, and trends over time rather than one snapshot. - A path from the comparison to a diagnosis of the gap and a recommended action. ### Follow-up Questions - Country Y has a much higher daily-to-monthly active ratio than X but far lower revenue per user. Is Facebook performing better or worse in Y? - How would you tell whether a gap comes from the product itself or from the market (data costs, local competitors, regulation)? - If you could show leadership only one number for each country, which would it be, and why?
