Tiered Application Support (L1–L3)
A structured support model with defined scope at each tier and escalation paths that are written down rather than improvised under pressure.
- L1 — first response, triage, known-error resolution, user guidance
- L2 — functional analysis, configuration fixes, data correction
- L3 — code-level debugging, defect fixes, vendor escalation
- Severity-based SLAs with escalation and communication protocols
- Extended-hours or follow-the-sun cover via US and India teams
