📦 Safety Stock & Stocking Rules

  • Safety stock targets aligned monthly across CSCP based on Weeks of Supply (WoS) targets
  • Only onboarded SIs stock at FSL: Ingrasys, Lenovo, Wiwynn (Quanta onboarding planned)
  • Only high-volume SKUs: minimum 20 racks per SKU at FSL; low-volume SKUs held at factory
  • Only Direct Warranty (DW) at FSL — SAP plans at MSPN level and cannot stock both SIW and DW (system design constraint)
  • Some inventory kept at factory for direct-to-DC shipments (geography + customs driven)
  • Actual on-hand at FSL includes cycle stock — ~20% higher than safety stock targets
