What Is Warehouse Order Picking?

Warehouse picking is a method of selecting items from inventory to fulfill customer orders. It is the most labor-intensive and time-consuming task in warehouse operations, accounting for up to 55% of operational costs in traditional warehouses.

Types of Order-Picking Methods

Efficient order picking is essential for smooth warehouse operations. Selecting the proper method can significantly reduce costs, improve fulfillment speed, and enhance customer satisfaction. Below are the most effective warehouse order-picking methods:

1. Single Order Picking

Best for: small warehouses with low order volumes.

How it works: A warehouse worker picks and processes one order at a time, navigating through the storage area to retrieve each item before moving on to the following order.

Advantages:

• Straightforward to implement with minimal training.
• Reduces confusion and mistakes since each order is handled individually.

Challenges:

• Time-consuming: Pickers must travel across the warehouse for every order, which leads to inefficiencies.
• Labor-intensive: Requires a larger workforce to maintain output, increasing costs.
• Not scalable: As order volumes increase, this method becomes unsustainable.

Example: A boutique e-commerce store handling a few dozen daily orders may use single-order picking to ensure each customer’s order is accurately fulfilled.

2. Batch Picking

Best for: Warehouses with high order volumes and multiple small-item orders.

How it works: A picker retrieves multiple orders simultaneously, consolidating similar items to reduce travel time. Pickers use carts or totes to collect items for several orders in a single trip.

Advantages:

• Reduces walking distance, improving productivity.
• It helps optimize picking time and workforce utilization.
• Works well when handling small, high-demand products.

Challenges:

• Requires careful organization and sorting to prevent order mix-ups.
• Not suitable for large or oversized items.

Example: An online grocery store using batch picking for small packaged food items ensures that pickers retrieve multiple customers’ orders in a single pass through the aisles.

3. Zone Picking

Best for: Large distribution centers with multiple SKUs.

How it works: The warehouse is divided into different zones, with pickers assigned to specific areas. Items for an order are collected from other zones and then consolidated before shipping.

Advantages:

• Reduces picker travel time, increasing efficiency.
• It avoids congestion in warehouse aisles.
• Enables specialization as pickers become familiar with their zones.

Challenges:

• Requires coordination to ensure orders are consolidated correctly.
• This can lead to delays if one zone is slower than the others.

Example: A fulfillment center for an electronics retailer might have separate zones for laptops, accessories, and peripherals, ensuring faster and more organized picking.

4. Wave Picking

Best for: Warehouses handling multiple shipping deadlines, such as e-commerce and retail distribution centers.

How it works: Orders are grouped into “waves” based on priority, shipping time, product category, or delivery location. Workers pick in organized waves to align with shipping schedules.

Advantages:

• Increases speed and accuracy by organizing orders efficiently.
• Optimizes workforce allocation and reduces idle time.
• Enables seamless synchronization with carrier schedules to ensure timely deliveries.

Challenges:

• Requires software systems to manage wave scheduling effectively.
• It can cause delays if waves are not appropriately balanced.

Example: An apparel distribution center might process morning orders as one wave and evening orders as another, ensuring efficient dispatch for same-day delivery.

5. Pick-to-Light and Voice Picking

Best for: High-speed environments like e-commerce fulfillment centers.

How it works: Workers receive picking instructions through digital LED displays (Pick-to-Light) or hands-free voice commands (Voice Picking). These systems guide pickers to the correct locations and quantities.

Advantages:

• Reduces human errors and improves accuracy.
• Boosts picking efficiency, particularly in high-speed environments.
• Shortens the time required for onboarding and training new employees.

Challenges:

• Demands an upfront investment in both hardware and software.
• It may not be suitable for all product types.

Example: A pharmaceutical warehouse might use pick-to-light systems to ensure accurate order fulfillment for prescription medications.

Addverb’s Automation in Order Picking: The Future of Warehousing

Traditional order-picking methods can be slow, error-prone, and labor-intensive. Adopting warehouse automation helps businesses boost productivity, reduce costs, and enhance accuracy. Here’s how automation is revolutionizing order picking:

4. Pick-to-Light(Rapido) and Pick-by-Voice(Zesty)

How they work: These systems provide hands-free picking instructions, reducing errors and improving workflow efficiency.

Benefits:

• Increases picking speed by guiding workers directly to items.
• Enhances order accuracy, reducing returns and complaints.
• Streamlines the onboarding process for new warehouse staff, ensuring faster integration and improved efficiency.

Example: A fulfillment center handling fast-moving consumer goods (FMCG) benefits from pick-to-light systems, ensuring quick and precise order processing.

1. Autonomous Mobile Robots (AMRs)

How they work: AMRs transport goods within the warehouse, reducing the distance workers need to travel. They can autonomously navigate warehouse aisles, retrieve items, and deliver them to packing stations.

Solution: Dynamo AMR optimizes picking routes, ensuring faster and more efficient fulfillment.

Benefits:

• Minimizes worker fatigue and increases efficiency.
• Minimizes reliance on manual labor while lowering operational expenses.
• Enhances safety by preventing collisions and congestion in aisles.

Example: A fashion e-commerce warehouse using AMRs can drastically reduce order fulfillment time, improving next-day delivery services.

2. Automated Storage and Retrieval Systems (ASRS)

How they work: ASRS uses robotic systems to store and retrieve inventory automatically. These systems use vertical storage to maximize warehouse space while improving picking speed.

Solution: Quadron Four-Way Shuttle provides high-speed, multi-directional material handling, perfect for warehouses with extensive SKUs.

Benefits:

• Maximizes storage capacity and optimizes inventory organization.
• Reduces errors by eliminating manual picking mistakes.
• Improves retrieval times, enabling faster order processing.

Example: A pharmaceutical distributor using ASRS can efficiently manage temperature-sensitive medications while ensuring accurate order picking.

3. Robotics-Assisted Sorting

How it works: Robotic arms and sorting systems assist workers in picking, packing, and sorting items at high speeds. These systems integrate AI to enhance efficiency.

Solution: Zippy Sorter automates sorting and order consolidation, handling thousands of items per hour.

Benefits:

• Reduces reliance on manual labor and lowers operational costs.
• Enhances accuracy and prevents order mix-ups.
• Seamlessly adapts to existing warehouse systems, improving efficiency and minimizing disruptions.
