The situation

You are the PM for activation and early retention at TuneLeaf. The growth team is celebrating strong sign-up volume, but the head of product is worried that usage is not sticking. Leadership wants a plan before next quarter planning because marketing spend is rising, and they do not want to keep paying for users who try the app once and disappear. Assume recent cohort data for new users looks like this: 100% sign up, 80% complete onboarding, 70% play at least one song in their first session, 30% return on day 2, 10% return by week 2, and 6% are active daily after week 4. The team has several ideas on the table, including onboarding changes, content features, notifications, social ideas, and pricing or ad changes, but engineering capacity is limited and different leaders are pushing different fixes. Your job is to frame the problem, decide what metrics matter most, identify where the biggest drop happens, and recommend what the team should test first.

What to produce

Write a 1 page product metrics memo, 700 to 900 words.

Your answer must

State the primary product problem in one sentence and define the goal you would optimize for.
List the 5 most important clarifying questions you would ask before committing to a solution.
Use the funnel data to diagnose where the main breakdown occurs and explain why that matters more than earlier steps.
Propose a north star metric and 2 to 4 supporting metrics for this problem, with a short reason for each.
Recommend 3 actions to test first, prioritized by expected impact and effort, and explain the tradeoffs.

Constraints

Assume no major new product area can be built this quarter.
You cannot rely on paid acquisition changes to solve the problem.
Your first release can include at most 2 engineering sprints of work.
Focus on free and premium users only if you explicitly explain whether they should be handled together or separately.

Format

Use short sections with headings: goal, questions, diagnosis, metrics, priorities.

How TuneLeaf actually played it

Covers a music app where only 6 percent of users are active daily after four weeks. The answer sets metrics, finds where engagement drops and suggests fixes.

Use cohort retention to see when users fall off
Link onboarding to the first habit moment
Choose a north star that reflects listening value
