Prompt

Business Process Flow for E-commerce Order Fulfillment. Use swimlanes to distinguish between the Customer, Order Management System (OMS), Warehouse, and Shipping Carrier. The flow starts with Order Placement, followed by an Inventory Check and Payment Authorization. If approved, the OMS routes the order to the Warehouse for Picking, Packing, and Label Generation. Finally, the package is handed over to the Carrier, triggering a tracking update notification to the customer.

Key flows

Show all (3)
  • Customer places an order, then the OMS performs Inventory Check (ATP/reservation) and Payment Authorization; if either fails, the order is held/cancelled and the customer is notified, otherwise the order is released to fulfillment.
  • Upon approval, the OMS routes the order to the Warehouse (WMS) for Picking and Packing; the warehouse generates a shipping label, assigns a tracking number, and updates the OMS shipment record with label/tracking details.
  • The packed parcel is handed over to the Shipping Carrier, which triggers a pickup scan; subsequent carrier tracking events flow back (API/webhooks/EDI) to the OMS, which sends tracking update notifications to the customer.
