  • Severity and escalation matrix
  • Communication channels and stakeholder updates
  • Ownership paths for active incidents

Incident operations

Reliable handling of active production events.

  • Triage and mitigation support
  • Coordination with internal engineering teams
  • Recovery tracking until service health is restored

Prevention loop

Reduce repeated incident load over time.

  • RCA quality and prevention backlog
  • Alert and runbook improvements
  • Operational reporting and next-step recommendations

What you get

Operational stability with a clear prevention loop.

  • Operational insights from incident trend reporting

Frequently asked questions

Do you provide 24/7 coverage?
Coverage depends on scope and model. We support backup, shared rota, and defined-hours options, with 24/7 when needed.
Is this only incident response?
No. We combine incident response with prevention work: alert hygiene, runbooks, and recurring issue elimination.
How is handover handled?
We define clear escalation paths, communication channels, and post-incident handover protocols from day one.
Can on-call be an add-on to another model?
Yes. On-call support is commonly added to staff augmentation or dedicated team engagements.
