| 1 | Inbound Receiving | Records purchase orders, advance shipping notices, received quantities, lot numbers, serial numbers, and inspection results. | Purchase order, ASN, barcode, QR code, lot and serial data. | Receiving accuracy, dock-to-stock time, and quantity variance. | Supplier data must match the item, unit-of-measure, and packaging structure configured in the WMS. |
| 2 | Inventory Control | Maintains real-time inventory balances by item, location, lot, serial number, status, and ownership. | Available, allocated, picked, damaged, quarantined, and blocked stock statuses. | Inventory accuracy, stock visibility, and adjustment frequency. | Location master data and consistent stock-status rules are essential for reliable availability calculations. |
| 3 | Put-away Optimization | Assigns received goods to storage locations according to product attributes, capacity, velocity, and operational rules. | Product dimensions, weight, storage class, turnover rate, and location capacity. | Put-away time, travel distance, storage utilization, and location compliance. | Accurate item dimensions and storage constraints improve slotting and reduce unnecessary movement. |
| 4 | Order Allocation and Picking | Releases orders and generates picking tasks using single-order, batch, zone, wave, or cluster picking methods. | Order priority, promised ship date, route, inventory availability, and picking sequence. | Picking accuracy, lines picked per labor hour, order cycle time, and short-pick rate. | The optimal picking method depends on order profile, SKU count, warehouse layout, and daily volume. |
| 5 | Replenishment Management | Moves inventory from reserve storage to forward-pick locations before stock reaches operational thresholds. | Minimum and maximum levels, demand forecast, open orders, and replenishment quantity. | Stockout frequency, replenishment completion rate, and picker waiting time. | Thresholds should reflect demand variability, storage capacity, case-pack quantities, and labor availability. |
| 6 | Packing and Shipping | Verifies picked goods, determines packaging requirements, prints shipping labels, and confirms carrier handoff. | Carton dimensions, weight, carrier service, tracking number, and shipping manifest. | On-time shipment rate, packing accuracy, carton utilization, and dispatch cycle time. | Carrier interfaces and label formats should be validated before production deployment. |
| 7 | Cycle Counting | Schedules targeted inventory counts without requiring a complete physical shutdown of warehouse operations. | ABC classification, count frequency, variance tolerance, and adjustment approval. | Count accuracy, unresolved variance, and adjustment value. | High-value or fast-moving items are commonly assigned more frequent counting intervals. |
| 8 | Traceability and Compliance | Tracks product movement, user actions, lot history, serial numbers, expiry dates, and inventory status changes. | FIFO, FEFO, lot genealogy, serial control, audit trail, and quarantine status. | Traceability completeness, expired-stock incidents, and audit exception count. | Business rules must reflect product regulations, customer requirements, and the applicable industry controls. |
| 9 | System Integration | Exchanges orders, inventory, master data, shipment confirmations, and status updates with surrounding business systems. | REST or SOAP APIs, EDI documents, CSV files, message queues, and database interfaces. | Interface success rate, transaction latency, data error rate, and reconciliation time. | Integration ownership, error handling, retry logic, and master-data governance should be defined in advance. |
| 10 | Automation and Analytics | Supports handheld terminals, mobile workflows, conveyors, sorters, AS/RS equipment, dashboards, and operational reporting. | Barcode scanning, RFID, equipment commands, labor activity, throughput, and warehouse task history. | Throughput, labor productivity, equipment utilization, order backlog, and process bottlenecks. | Automation projects require clear process mapping, equipment interfaces, safety controls, testing, and user training. |
