When To Use Order Pickers: Picking Strategies, Alternatives, and Throughput

Order pickers excel in environments where individual-case or each-level picking from racks is frequent, especially in e-commerce, retail replenishment, and B2B case-pick operations. They are most effective when pickers must access multiple SKU levels within a single trip and when orders have low to moderate lines-per-order but high lines-per-hour requirements. However, alternatives such as pallet pickers, goods-to-person systems, or manual picking carts may be more efficient in other scenarios.

Why Order Pickers Matter For Certain Picking Profiles

Order pickers reduce travel time and increase time spent actually picking when racks are deep and SKUs are spread across multiple levels. Their vertical reach allows one operator to handle picks across several tiers without additional equipment like ladders or cherry pickers.

Picking Strategies That Favor Order Pickers

• Piece Picking in E-commerce: Many single-item orders with SKUs stored across rack levels benefit from the operator’s ability to work at height efficiently.
• Zone Picking With Height Access: In a zoned layout where one zone covers multi-level racks, order pickers enable a single-zone operator to pick across levels without handoffs.
• Batch Picking: Batch orders grouped by SKU or location reduce travel and make order pickers more productive when combined with good routing.

When Alternatives Are Better

Not every operation needs order pickers. Consider alternatives when these conditions apply.

• High-Volume Pallet Loads: If most orders are full-pallet shipments, forklifts or pallet jacks are the appropriate choice.
• High-Density Small-Item Picking: Goods-to-person systems or conveyor-based picking can outperform order pickers for very high-line count environments.
• Low Throughput, Low Height: Manual picking with carts or reach-in shelving may be sufficient for low-volume, low-height operations.

How To Measure Order Picker Productivity

Key performance indicators help decide whether order pickers are the right fit and when to add more units.

• Lines Per Hour (LPH): Measures how many pick lines an operator completes per hour; order pickers should demonstrate higher LPH than manual low-level picking in similar layouts.
• Order Cycle Time: Time from pick start to order completion, useful for comparing batch vs single-order strategies with pickers.
• Utilization: Percentage of available time an order picker is in productive use; helps justify purchase or lease.

Integration With WMS And Picking Technology

Order pickers are most effective when integrated with warehouse management and pick-routing systems that minimize travel and balance workload.

• WMS Routing: Put-to-light or pick-to-light guidance and optimized aisle routing reduce decision time at rack faces.
• Wearable Scanners: Hands-free scanning and voice picking reduce handling time and speed verification at height.
• Telematics: Monitor travel distances and idle time to spot routing inefficiencies and justify layout changes.

Practical Example: Choosing Between Pickers and Goods-To-Person

A retailer handling 10,000 SKUs with moderate daily order volume tested two layouts: a traditional rack layout with order pickers and a compact automated goods-to-person (GTP) cell for its top 2,000 SKUs. The hybrid approach used order pickers for slow-moving multi-level SKUs and GTP for the top movers. The result: improved throughput for high-velocity SKUs via automation while maintaining flexibility and lower capex for slow movers through order pickers.

Tips For Deciding To Deploy Order Pickers

• Map your orders: Analyze lines per order, SKUs per order, and pick locations to determine travel vs pick balance.
• Pilot first: Run a short trial in a representative zone to measure LPH and utilization before wide rollout.
• Combine strategies: Use order pickers alongside conveyors or GTP to optimize across SKU velocity bands.
• Consider ergonomics: Choose units with adjustable controls and good vibration dampening to reduce operator fatigue at height.

In short, the Order Picker is ideal when picking requires vertical access to multiple rack levels and orders are composed of scattered case or each picks. Use data-driven pilots and WMS integration to confirm throughput gains, and combine order pickers with automation selectively to align cost, speed, and flexibility.
