Escalation chain
A defined sequence of who is notified, and when, as a problem becomes more serious, such as budget checkpoints at 50, 75, 90 and 100% each reaching a different audience. A ZopNight budget sends at most two alerts (one optional threshold plus exceeded), so further steps are a team process. Why it matters: It makes sure the right people act before an overrun becomes a surprise.
