📋 Overview
The Outbound Work Area TabPage is a dedicated calculation screen specifically focused on determining the necessary floor space for active work operations in the outbound shipping area. It calculates required square footage for picking, sorting, inspection, and packing stages in high detail.
💡 What is the Outbound Work Area?
The outbound work area refers specifically to the active physical work zones required to process outgoing orders. It comprises the following functional sub-areas:
- Picking Area: Active retrieval and picking aisles
- Sorting Area: Order-consolidation and batch sorting stations
- Inspection Area: Quality verification workbenches
- Packing Area: Packaging workstations and boxing tables
- Labelling Area: Shipping document and label application stations
- Material Staging Area: Cart holding, packing materials, and tote supply staging
🔄 Difference from General Shipping Space
Relationship Between "Shipping Space" and "Outbound Work Area"
| Category | General Shipping Space | Outbound Work Area |
|---|---|---|
| Scope | Total outbound facility footprint | Active processing workbenches & aisles only |
| Elements Included | Workbenches + Truck Docks + Holding Buffers + Aisles | Active processing zones only (picking, sorting, inspection, packing) |
| Calculation Focus | Macro building footprint | Micro station layout & workstation count |
| Primary Purpose | Overall facility master planning | Workstation layout & staffing plans |
| Granularity | Zone-level estimation | Station & workbench detailed modeling |
When to Use Which Tab
| Planning Phase | Target TabPage | Reason |
|---|---|---|
| Concept / Master Plan | General Shipping Space | Establishing overall building footprint |
| Basic Engineering | Both Tabs | Balancing total footprint with active zone distribution |
| Detailed Layout Design | Outbound Work Area | Fine-tuning aisle travel & workbench numbers |
| Staffing & Shift Planning | Outbound Work Area | Calculating operator headcount by process stage |
| Process Kaizen | Outbound Work Area | Identifying operational bottlenecks |
We recommend a two-stage design approach: first establish total building footprint using "General Shipping Space", then perform micro-layout modeling in "Outbound Work Area".
🎯 Purpose & Applications
1. Optimal Work Area Design

Detailed Process Breakdown
1. Picking Area
Function: Retrieving ordered SKUs from storage media.
Key Drivers:
- Pick Rate Productivity (pieces / hour / person)
- Daily Outbound Workload (pieces / day)
- Operating Hours & Required Operators
- Storage Location Density (SKUs / m²)
- Aisle Clearance Ratio (30–60%)
2. Sorting Area
Function: Consolidating batch-picked SKUs by order or destination.
Key Drivers:
- Sorting Productivity (items / hour / person)
- Number of Sorting Stations
- Destination Chute / Put-wall Count
- Footprint per Station (4–10 m²)
3. Inspection Area
Function: Verifying SKU accuracy prior to packing.
Key Drivers:
- Audit Productivity (orders / hour / person)
- Audit Sampling Rate (0–100%)
- Inspection Bench Count
- Footprint per Station (3–6 m²)
4. Packing Area
Function: Boxing, void-fill, and sealing orders.
Key Drivers:
- Packing Productivity (orders / hour / person)
- Pack Cycle Time (minutes / order)
- Packing Workbench Count
- Footprint per Bench (4–10 m²)
5. Labelling Area
Function: Applying shipping manifests and carrier labels.
Key Drivers:
- Labelling Productivity (orders / hour / person)
- Label Cycle Time (seconds / order)
- Station Footprint (2–5 m²)
6. Material & Staging Prep Area
Function: Staging consumables, carts, and charging stations.
Key Drivers:
- Box & Void-fill Rack Footprint
- Pick Cart & Tote Staging
- RF Terminal / Scanner Charging Racks
- Waste & Recycled Box Dumpster Space
📝 Input Parameters
Common Baseline Parameters
| Parameter | Description | Unit | Standard Range |
|---|---|---|---|
| Daily Outbound Workload | Total daily volume | Pieces/day or Orders/day | 1,000 – 100,000 |
| Operating Hours | Daily active working hours | Hours/day | 6 – 24 |
| Peak Multiplier Factor | Peak vs average volume ratio | Multiplier | 1.2 – 2.5× |
| Aisle Clearance Ratio | Aisle space relative to workbenches | % | 30 – 60% |
🔢 Calculation Logic
Total Work Area Footprint Formula
Picking Area = 22.5 m²
Sorting Area = 80.0 m²
Inspection Area = 8.0 m²
Packing Area = 30.0 m²
Subtotal = 140.5 m²
Material Prep Area (8%) = 140.5 × 0.08 = 11.2 m²
Total Outbound Work Area = 140.5 + 11.2 = 151.7 m²
⚠️ Important Notes & Constraints
1. Process Selection Appropriateness
⚠️ Not all process steps are required for every DC
Required process steps vary based on order profiles:
- Single Picking Mode: Sorting area is not required.
- B2B Bulk Shipments: Packing stations can be simplified.
- High Vendor Quality: Outbound audit inspection can be omitted.
