Develop a phased plan to reposition inventory across [DCList] and introduce cross-dock waves to support [SKUCount] SKUs, reducing dwell to [TargetDwellHours] and backorders costed at [BackorderCost]. Time moves to match promotion and launch calendars [RegionalPromotionsCalendar], carrier cut-offs, and yard capacity. Sequence SKU migrations to minimize split-shipments and middle-mile deadhead; include seasonal safety stock timing. Output format: (1) Reallocation table [SKU/Family, From, To, Wave, Start, End, OTIF Δ, Cost Δ]; (2) Cross-Dock Schedule [Day, Inbound Windows, Outbound Waves, Dock Utilization %]; (3) KPI pack (Fill Rate, Dwell, Split-Rate, Cost/Order) pre/post; (4) Constraints & mitigations list. Provide a final recommendation by phase with stop/continue criteria.
