Root-Cause Analysis of a 20% Decline in Google Cloud Subscriptions

You are a product manager at Google. When you arrive at the office, you find that the number of Google Cloud subscriptions has dropped by 20%. Walk through what you would do: how you would confirm the drop is real, find out what caused it, judge how much it matters, and decide on next steps. ```hint Find the flow that moved The number of active subscriptions can only fall because fewer customers start paying, more customers stop, or fewer lapsed customers return. Rule out a reporting problem first, then work out which of those changed and for which customers. ``` ### Clarifying Questions - Which product does "Google Cloud subscription" refer to: paid Google Cloud accounts used by businesses and developers, Workspace plans, or Google One storage plans bought by consumers? - Is the 20% a fall in the total number of active subscriptions, or in the number of new subscriptions started per day or week, and against which baseline? - Did the drop appear overnight or build over weeks, and is it global or concentrated in particular regions, customer sizes or payment methods? - Did any price change, billing or checkout release, outage or account-policy change happen in the same period? ### What a Strong Answer Covers - Pinning down the product, the metric definition (active subscriptions versus new ones), the time window and the baseline before diagnosing. - Ruling out data freshness, pipeline and definition problems before looking for business causes. - Breaking the subscription count into acquisition, churn and reactivation, then segmenting to localize the decline. - Internal and external hypotheses checked in a sensible order, with the timing and shape of the drop used as evidence. - Sizing the revenue and customer impact and ending with concrete actions, owners and communication. ### Follow-up Questions - Suppose almost all of the lost subscriptions are renewals whose card payments failed in one region. What do you do in the first day, and what would stop this from going unnoticed again? - Subscriptions are down 20% while Google Cloud revenue is nearly flat. How do you read that, and does it change how urgently you act? - If the decline traces back to a price increase announced a month earlier, how would you decide whether to keep, adjust or reverse it?
