Executive Summary & Scope

This document mandates the standardized procedures for inbound logistics, inventory storage, and outbound fulfillment at Template Registry facilities. It applies to all warehouse personnel and third-party logistics (3PL) partners. The objective is to achieve 99.9% inventory accuracy and zero-defect fulfillment cycles through rigorous process adherence.

Prerequisites & Required Tools

• Hardware: Handheld RFID/Barcode Scanner (Scanner-Gen4), Class II Safety Footwear, High-Visibility Vest.
• Software: Enterprise Resource Planning (ERP) Module (WMS-Cloud 4.0), Inventory Management System (IMS).
• Compliance: OSHA 29 CFR 1910 Subpart N (Materials Handling and Storage).
• Safety: Ergonomic lifting belt, PIT (Powered Industrial Truck) certification.

Roles & Responsibilities (RACI)

Step-by-Step Procedure

Phase 1: Inbound Receiving & Verification

• Verify incoming manifests against the Purchase Order (PO) in WMS-Cloud.
• Inspect shipping containers for structural damage upon arrival.
• Scan individual SKU barcodes; reconcile quantities immediately.
• Tag items with RFID tracking labels for system entry.

Phase 2: Inventory Put-away

• Direct goods to pre-assigned storage zones based on SKU velocity (Fast/Medium/Slow).
• Validate shelf location accuracy via handheld terminal scan.
• Execute inventory replenishment trigger if stock levels fall below safety thresholds.

Phase 3: Picking & Order Fulfillment

• Generate pick-lists prioritized by shipping deadline and transit zone.
• Follow the "optimized path" sequence generated by the WMS to minimize floor transit time.
• Validate item selection via barcode scan to prevent picking errors.

Phase 4: Packing & Dispatch

• Execute weight-verification check on every outbound parcel.
• Apply compliance shipping labels and generated manifest.
• Transfer custody to the carrier with documented sign-off.

Quality Assurance & Verification

• Metric Thresholds:
  • Inventory Accuracy: >99.9%
  • Order Cycle Time (Dock-to-Stock): <4 hours
  • Pick Accuracy: 99.95%
• Common Pitfalls: Failure to scan at each hand-off point, improper storage of hazardous materials, and bypassing the weight-verification gate.
• Audit Checklist: Monthly physical cycle counts, quarterly safety equipment inspection, and weekly ERP data synchronization health check.

Troubleshooting FAQ

Scenario 1: System-Physical Mismatch (Inventory Discrepancy)

• Solution: Immediately isolate the bin location. Perform a blind cycle count. If variance persists, flag the item as "Pending Investigation" in the IMS and escalate to the Ops Manager for a root-cause analysis of the last three transactions.

Scenario 2: Barcode Scanner Connectivity Failure

• Solution: Toggle the terminal radio frequency (RF) connection. If persistent, move the device to a localized docking station to re-sync with the server. If failure continues, utilize the "Manual Entry Override" mode and submit the paper backup to the Shift Lead for batch processing within 60 minutes.

Scenario 3: Damage Discovery During Pick

• Solution: Cease picking of the damaged SKU. Quarantine the unit in the designated "Damaged Goods" cage. Record the incident in the WMS "Exception Report" module with a photo attachment for insurance/vendor credit processing.
