Prioritize Experiments Like a PM: Activation Metrics First

Who This Helps

This is for product managers who want to stop wasting time on low-impact experiments. You have a backlog of ideas, but you're not sure which one moves the needle. The Product Metrics Basics course gives you a simple way to turn product questions into measurable decisions.

Mini Case

Priya, a PM at a fitness app, had three experiment ideas. She used activation metrics from the course to pick one. Her activation definition was "complete 3 workouts in 7 days." She found that only 12% of new users hit that milestone. The biggest drop-off happened on day 2. So she prioritized an experiment to improve the day 2 experience. That one move increased activation by 18% in two weeks.

Do This Now (5 Steps)

1. Pick one activation event. From the course, define it as one action and one time window. Example: "complete 3 workouts in 7 days."
2. Check your current rate. How many users hit that event? If it's below 20%, you have a clear problem.
3. Find the biggest drop-off. Look at the steps before the event. Where do most users stop? That's your experiment target.
4. List your experiment ideas. Write down 3 to 5 options that address that drop-off.
5. Rank by potential impact. Choose the one that could move the activation rate the most. That's your next experiment.

Avoid These Traps

• Picking a metric that's too broad. Total sessions don't tell you where to act. Stick to activation.
• Running multiple experiments at once. You won't know what worked. Test one change at a time.
• Ignoring the time window. If your activation event takes 30 days, you wait too long to learn. Keep it under 7 days.
• Using definitions that drift. The course shows how Priya fixed this by writing one clear definition for her team.
• Forgetting guardrails. A North Star metric is great, but you need guardrails to avoid hurting retention or revenue.

Your Win by Friday

By Friday, you will have one activation metric defined, its current rate measured, and one experiment prioritized. That's it. One clear decision that focuses your team on the highest-impact move. And you'll feel a lot less scattered.

Fun fact: Priya's team now calls their activation metric "the Friday number." It's the one thing they check before the weekend. You can have your own Friday number too.
