Product Analytics for Circle (Groups-like Feature)
Scenario
Circle is a new groups/community feature on a social platform, similar to Facebook Groups. The product team wants to understand how to measure success and where to focus: small private groups (≈5–6 members) or large public groups (tens–hundreds of members).
Tasks
-
Define the success metrics you would track for Circle. Omit guardrail metrics and cannibalization concerns.
-
Using only retrospective (observational) data, decide whether Circle should optimize for small private groups or large public groups. Describe the analysis plan in detail and specify a data-driven decision rule.
-
Suppose you have three plotted lines of “total comments ÷ total posts” across different products. Can these lines be directly compared? Explain when and how such comparisons are valid or invalid.
