Diagnose a KPI Drop with a First-30-Minute Incident Triage

Who This Helps

This is for team leads who need to stop the frantic search when a dashboard turns red. It’s part of the Data Reliability Leadership course, which helps you build trust by running calm, structured incident drills.

Mini Case

Your weekly active user report drops 15% overnight. The team spends 2 hours checking dashboards, asking Slack, and guessing about a recent deploy. Sound familiar? With a triage card, you’d have pinpointed a broken data ingestion job in 25 minutes.

Do This Now (5 Steps)

1. Call the huddle. The moment a critical KPI alert fires, gather the core team for a 30-minute max call. No spectators.
2. State the contract. Remind everyone of the data contract for this metric. Which source tables and transformations define it? This is your north star.
3. Trace upstream. Start from the final number and work backward. Check the final table, then the transformation job, then the raw source data. Look for gaps or errors at each step.
4. Assign one detective. Give one person the sole task of investigating the most likely broken link. Everyone else mutes and researches quietly.
5. Decide the next action. At 25 minutes, decide: Is the root cause found? Do you need to pause a data pipeline? Who communicates to stakeholders? Your goal is a clear next step, not a full fix.

Avoid These Traps

• Don’t let the meeting become a brainstorming session for every possible cause. Stick to the trace.
• Don’t skip reviewing the data contract. Definitions drift, and you might be measuring the wrong thing.
• Don’t allow more than 5 people in the huddle. Too many cooks spoil the triage.
• Don’t forget to note what you checked. This becomes your postmortem starter kit.
• Don’t try to solve the problem in the first 30 minutes. Your job is diagnosis, not surgery.
