Diagnose Your KPI Drop with a Product Portfolio Health Check

Stop guessing why your metric fell. Use a focused 60-minute session to find the real cause and decide what to fix first.

Who This Helps

This is for Product Managers who see a key number drop and need to stop the blame game. It uses the core question from the Product Portfolio Strategy course: 'What is the weakest link in our product mix right now?' Instead of chasing every theory, you'll focus your team on one problem.

Mini Case

Your team's weekly active users dropped 18% last month. The support team says it's a bug. Marketing says it's a competitor's new feature. Engineering says it's seasonal. You have 7 different hypotheses and a stressed-out team. Sound familiar? We'll fix that.

Do This Now (5 Steps)

  1. Block 60 minutes on your calendar. Right now. Call it 'KPI Triage.' This is your focused session.
  2. Grab one number. Not ten. Pick the single KPI that dropped (like that 18% user drop). Write it on a virtual whiteboard.
  3. List every product change from the last 30 days. New launches, pricing tests, even small feature tweaks. Aim for at least 8 items.
  4. Map each change to the KPI timeline. Did the drop happen 2 days after launch? A week after a price change? Look for the closest match.
  5. Vote on the #1 most likely cause. Get your core team to vote silently. The winner is your hypothesis to test. The rest go in a 'parking lot' for later.

Avoid These Traps

  • Trap 1: Chasing the loudest voice. The person who talks most doesn't always have the right answer. Use the silent vote.
  • Trap 2: 'It's probably everything.' This leads to no action. Force yourself to pick one primary cause to investigate.
  • Trap 3: Endless data digging. Don't spend 3 days building the perfect dashboard before you have a guess. Test your #1 hypothesis with a simple experiment first.
  • Trap 4: Skipping the small stuff. That tiny UI text change you forgot about? It might be the culprit. List everything.

Your Win by Friday

By Friday, you'll have a single, testable reason for your KPI drop. You'll move from 'What's happening?!' to 'We think it's X, and here's how we'll check.' Your team will feel clear, not chaotic. You'll have a plan instead of a panic. Go find that root cause—you've got this.
