Google Drive PM: Choose a North-Star Metric, Supporting Metrics and Guardrails

You are the product manager responsible for Google Drive. Which metrics would you focus on, and how would you rank them? ```hint Value before volume Decide what it means for a person to get real value from Drive in a given week. Totals such as files stored or accounts created can keep climbing even when people get less out of the product. ``` ### Clarifying Questions - Should I focus on consumers who use Drive for personal files and backup, on businesses and schools that use Drive inside Google Workspace, or both? - Is the current priority engagement, retention, or revenue from paid storage plans and Workspace seats? - For this exercise, does Drive include the Docs, Sheets and Slides editors, or only file storage, sync and sharing? ### What a Strong Answer Covers - A stated goal and user segment that the metric choices follow from - A precisely defined north-star metric that reflects value delivered rather than storage volume or sign-ups - A short, ranked set of supporting metrics across activation, engagement, retention and monetization, each with a reason - Guardrail metrics for sync reliability, data safety, sharing abuse and cost to serve - How the metrics would be segmented, and how conflicts between them would be resolved ### Follow-up Questions - Your north-star metric is flat while total storage keeps growing. What could explain that, and what would you check first? - How would your metric set change if you owned Drive for Workspace business customers instead of consumers? - You are testing a prompt that nudges free users near their storage limit to upgrade. Which metrics decide whether it ships?
