A senior SuccessFactors help desk. Not a triage layer that forwards everything to L3 — actual SF specialists answering on the first call.
SLA-backed ticket response by severity (P1: 2 hours, P2: 8 hours, P3: 1 business day); senior SF consultants on the first call; knowledge base populated with solved tickets; escalation path to SAP support when needed; and monthly ticket-volume and resolution-time reporting.
User issues solved on the first call — not routed through three layers of triage.
