Who This Helps
This is for team leads who see a sudden dip in a key metric. Maybe your user activation dropped 15% last week. You need to know why, but your team is already busy. This routine uses the Product Portfolio Strategy approach to turn a messy investigation into a clean, one-hour diagnosis. No more week-long rabbit holes.
Mini Case
Your team's core feature adoption metric slipped from 42% to 35% over seven days. Panic starts. Instead of a full-team fire drill, you run this focused session. You discover the drop isn't across all user segments—it's isolated to new users who signed up after a specific marketing campaign changed. That's a 7-point drop with a clear starting point. Now you know where to look.
Do This Now (5 Steps)
- Grab your last stable number. Write down the KPI value from before the drop. For example, "Activation was at 42% on May 1."
- Plot the exact drop point. On a timeline, mark the day the metric first fell. Look for any product launches or external events that day.
- Slice by one core user segment. Pick your biggest user group. Check if the drop happened for them, or just a smaller group. This tells you if it's widespread or targeted.
- Check one related metric. If your main KPI is activation, look at the sign-up completion rate for the same period. Did it also change?
- Form your one-sentence hypothesis. Based on steps 3 and 4, write your best guess. For example: "The drop seems linked to new users from the May 5 campaign who aren't seeing the onboarding tutorial."
Avoid These Traps
- Don't jump into deep data analysis before checking the simple segments first. You'll waste hours.
- Don't call a meeting without your one-sentence hypothesis. You'll get unfocused opinions.
- Don't try to diagnose more than one KPI at a time. Stay focused on the main drop.
- Don't ignore small, recent changes in other parts of the business, like a tweaked email or updated help text.
Your Win by Friday
By Friday, you'll have a clear, evidence-based reason for that KPI drop. You'll present it to your team in two minutes, not twenty. You'll have a targeted action—like fixing a single onboarding step—instead of a vague "improve activation" goal. Your team gets clarity, and you get your evening back. That's a solid win.
