Your question is Compare Retention After Feature Adoption. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
You are a product growth analyst at a B2B fleet management platform, and your team recently launched a new workflow in the driver safety experience that lets fleet admins create automated coaching follow-ups after unsafe driving events. In the last 8 weeks, 28% of newly activated accounts adopted the workflow within their first 14 days, and those accounts appear to have 12-week retention of 61% versus 46% for accounts that did not adopt it. Product leadership wants to know whether feature adoption is actually associated with better retention or whether the gap is mostly explained by differences in account size, onboarding quality, or initial engagement.
How would you use cohort retention to compare users who adopted the feature versus those who did not, and how would you determine whether the observed retention gap reflects true feature value rather than selection bias?
