Who This Helps
This is for product managers who see a key metric dip and need to move from worrying to fixing. It uses the 'Unit Economics Snapshot' mission from the Founder Finance Basics Mission Pack to give you a clear, one-page truth.
Mini Case
Ben's revenue grew 15% last month, but his cash balance didn't budge. He felt stuck. In one 45-minute session, he built a unit economics snapshot. He found his cost of goods sold (COGS) had quietly crept up from 22% to 31% of revenue. That was the leak. He fixed his supplier contract the next week. No more flat cash.
Do This Now (5 Steps)
- Block 60 minutes on your calendar. Close your email. This is your investigation time.
- Grab your last 90 days of data for revenue, direct costs, and any channel spend.
- Calculate your core unit economics: Contribution Margin per customer. (Revenue per customer minus direct costs per customer).
- Compare this period to the last. Look for shifts of more than 5%. That's your signal.
- Write your one-sentence diagnosis. For example: 'CAC increased 40% because we over-invested in a low-converting channel.'
Avoid These Traps
- Don't jump to the first conclusion. Correlation isn't causation.
- Avoid analyzing ten metrics at once. Pick your one north star KPI and its direct drivers.
- Don't skip the comparison. A number in isolation tells you nothing.
- Resist the urge to call an emergency meeting before you have your one-page snapshot.
- Don't mix in new feature ideas. This session is for diagnosis, not solution brainstorming.
- Avoid using averages that hide spikes or drops in the data.
- Don't forget to look at customer segments separately. A problem might be in just one group.
- Never diagnose without checking the data quality first. A reporting bug can cause a fake drop.
Your Win by Friday
By Friday, you'll have a single, clear answer to 'What caused the drop?' pinned to your monitor. You'll walk into your next team sync with a fact, not a fear. You'll have reclaimed hours previously spent in circular debates. And you'll have a repeatable playbook for the next time a KPI wiggles. That's a calm, confident week.
