Who This Helps
You're a growth marketer who just saw a key channel metric drop 12% overnight. Your gut says "seasonality" but your boss wants a real answer. This is for anyone tired of guessing and ready to find the real root cause in one focused session.
Mini Case
Meet Mei, a growth marketer at a mid-size SaaS company. Her team's trial sign-ups dropped 12% in one week. Instead of panicking, she used a structured approach from the Data Reliability Leadership program. She ran a 30-minute triage session, checked her data contracts, and found the issue: a broken tracking pixel on the new landing page. Fix took 3 hours. Sign-ups recovered in 2 days.
Do This Now (5 Steps)
- Grab your metric's data contract. If you don't have one, write a quick one: what's the metric, where does it come from, who owns it. This is your anchor.
- Check the last 7 days of data. Look for sudden changes in volume, source, or timing. A 12% drop often has a clear timestamp.
- Run a 5-minute incident triage. Ask: "What changed?" Check deployments, campaigns, or third-party tools. Write down three possible causes.
- Verify the data source. Is the tracking code still live? Did a partner update their API? A quick look can save hours.
- Talk to one stakeholder. Ask the person closest to the data: "Did anything change yesterday?" Their answer might be your root cause.
Avoid These Traps
- Don't blame seasonality without checking. It's the easy answer, but often wrong.
- Don't jump to fix before you diagnose. A quick patch might hide the real issue.
- Don't work alone. A 2-minute chat with a teammate can reveal what you missed.
- Don't ignore small drops. A 3% dip today can become 12% tomorrow.
- Don't forget to document. Write down what you find—future you will thank you.
- Don't assume your data is clean. Trust but verify, especially after a change.
- Don't skip the data contract. It's your map when you're lost.
- Don't overthink it. One focused session is enough to find the root cause.
