Senior SRE attrition is the most expensive turnover in engineering: $300K-$600K per replacement, and it's almost entirely on-call burnout.
The dominant cost of bad on-call is not the minutes spent paging, it's that your senior engineers eventually quit. The cost to replace one senior SRE (recruiting, onboarding, time-to-productivity, lost institutional knowledge) is $300K-$600K. Most teams optimize for the wrong number, they squeeze the alert noise but don't change the structure that produces it. Senior engineers see no end and leave.
Nova attacks on-call burden at the source: noise reduction, agent-first remediation, and runbook autonomy that keeps humans in the loop only when needed.
Routine pages close themselves through agents within policy. The on-call schedule covers escalation, not the whole flood.
Nova's correlation and anomaly detection take the actual alert volume from thousands per day to dozens. Senior engineers stop being human filters.
Nova's on-call management supports follow-the-sun rotations, primary/secondary tiers, paid compensation tracking, and zero-gap handoffs. Schedules that were untenable become livable.
