You just joined as the PM on a habit-tracking app.
In week one, the data team flags something: people who signed up in the last two months are completing fewer habits by their second week than users did six months ago.
Same onboarding.
Same features.
Something has slipped.
Here's your context and constraints:
- Signups are steady, so this isn't a top-of-funnel or marketing problem.
- You get one small engineering fix this sprint. Not three. One.
- Nobody on the team has talked to a churned user in months.
This is the kind of open-ended question a real PM interview throws at you.
There's no single right answer. The whole game is how you think.
So: how would you figure out what's going on, and where would you start?
Walk us through your approach in the comments.
I'll post how a strong PM would structure it on Wednesday.
