Root-causing spend variance in under an hour

Variance reviews often turn into guesswork. A crisp process finds the driver fast and communicates it clearly.

The flow

Before diving in, set expectations for owners and timing before diving into the details.

  • Confirm data freshness; stale exports derail everything.
  • Use spending flow to identify which project or service drove the change.
  • Check deployment timelines and usage metrics for the culprit service.
  • Decide if the variance is expected (seasonality, launch) or risky.
