Who This Helps
This is for product managers who want to turn product questions into measurable decisions. If you're in the Finance Basics for Operators course, you already know that cash and profit tell different stories. Now let's use that to prioritize experiments.
Mini Case
Viktor runs a subscription product. His team has three experiment ideas: a new pricing tier, a referral program, and a feature upgrade. He uses unit economics to decide. His contribution margin is 40%. The pricing tier experiment could lift it to 52%—a 12% gain. The referral program might add 7 days to customer lifetime. The feature upgrade? No clear metric. Viktor picks the pricing tier. That's a measurable decision.
Do This Now (5 Steps)
- Pull your unit economics snapshot. Find your contribution margin per unit. If you don't have it, calculate it: revenue minus variable costs, divided by revenue.
- List your next three experiment ideas. Write each one down. No filtering yet.
- Estimate the impact on one key metric. For each idea, guess the change in contribution margin, customer lifetime, or cost per acquisition. Use real numbers, not hopes.
- Rank by highest potential gain. The idea with the biggest lift in your weakest metric wins. If two are close, pick the one with lower effort.
- Run that experiment this week. Set a clear success threshold. For example, if contribution margin doesn't hit 48% in 14 days, stop.
Avoid These Traps
- Falling in love with a feature. The feature upgrade felt cool, but it had no measurable impact. Don't let excitement override data.
- Ignoring cash rhythm. A great experiment that drains cash too fast is still a bad move. Check your runway first.
- Overcomplicating the math. You don't need a spreadsheet with 50 rows. One number—contribution margin—is often enough.
- Waiting for perfect data. Viktor didn't have exact numbers for the referral program. He used a reasonable estimate and moved on.
Your Win by Friday
By Friday, you'll have one experiment prioritized based on unit economics, not gut feel. You'll know exactly why you picked it and what success looks like. That's a measurable decision. And you'll have more time for coffee—or a nap.
