Daytime dashboards can look calm while the night schedule quietly doubles machine hours. The pattern shows up often in Australian product teams that keep generous branch retention and full rebuild habits inherited from an earlier, smaller estate.
What to pull first
Ask for machine-hour exports by hour-of-day and by branch class. You do not need a perfect cost model on day one—only enough to see whether nights and stale branches dominate.
Policy before tooling
Many cost climbs reverse with retention rules and rebuild frequency changes. Buying another scheduler rarely fixes a policy that rebuilds everything “just in case.”
When to call for a review
If finance notices the invoice before engineering notices the clocks, schedule a compile cost review. Bring the exports; leave the blame narrative at the door.
