You are the PM for the rider experience in a large ride-hailing app with 25M monthly active riders across multiple cities. Leadership wants to launch a new rider-facing feature in the main app to improve retention because 30-day rider retention has stalled at 42%, and riders who take only 1 trip in their first 2 weeks are 3x more likely to churn by day 60. The team believes there is room to improve repeat usage among occasional riders, but the feature goal is still broad: “increase rider retention.” You need to turn that goal into clear product requirements and a measurable definition of success before development begins.
How would you translate this retention goal into product requirements and metrics, and how would you decide what kind of feature is worth building first?
