E-commerce Warehouse Picking

What is Warehouse Picking?

Warehouse picking is one of the most essential elements of order fulfillment, where the warehouse order picker takes individual items from the fulfillment facility as per the customer’s needs. In simple words, it is the process of warehouse order picking from the fulfillment facility so sellers can take the individual items to the customers. It is also considered to be one of the most expensive and labor-intensive activities in the order fulfillment process.

What is Warehouse Order Picking?

Warehouse order picking means more or less the same as warehouse picking. It is the process of taking the necessary items from the inventory and getting them ready for shipment. The warehouse order picker goes to the fulfillment facility and with the help of a handheld scanner, locates the products for that particular order.

Warehouse order picking is the first and foremost step in the process of order fulfillment. When the warehouse picker gets the right order from the fulfillment warehouse, they move one step closer to delivering the right products to the customers and attaining customer satisfaction.

Warehouse Picking Strategies

Warehouse Picking is among the first and one of the most important steps of order fulfillment, and it is necessary to do it properly. While the warehouse picker is responsible for the order picking, the manager or the supervisor derives the strategies that can be adopted for the same.

Warehouse Picking

4 warehouse picking strategies you need to know:

Batch Picking

The preparation of multiple orders at the same time is called batch picking. When this strategy is followed for warehouse picking, the warehouse order picker collects multiple orders from different clients, or as per the needs of production, in a single trip. The supply chain 24/7 has reported that almost 50% of the time used for picking is spent on travel, so this batch picking strategy is executed by the supervisors so the travel time is saved by picking multiple orders at the same time.

The batch picking strategy works best for warehouses that have a large space and have multiple clients who have requested various orders. A segmented warehouse cart should also be used to apply this strategy, where a substantial number of items can be stored in the warehouse, and the warehouse picker can keep track of the orders accordingly.

Zone Picking

The zone picking strategy is applied when there are various types of items that are to be stored in the warehouse. In this case, each warehouse picker is assigned a zone of similar orders, and that warehouse order picker is responsible for picking all the orders that are related to that particular zone.

The availability of warehouse automation systems makes it best to work with the zone picking strategy. It can divide the facility into different sections categorized based on product description, the demand for the products, or any other criteria whatsoever.

Wave Picking

With this strategy, the warehouse order picker moves around the entire fulfillment facility to pick up orders of different clients and various items from different zones under the supervision of the supervisor or warehouse manager. Therefore, wave picking is also called the strategy that combines batch picking and zone picking.

To practice the wave picking strategy, the warehouse should be large enough to prepare the individual orders to properly execute order preparation. Also, devices like barcode scanners help the employees to pack the products for the clients efficiently.

Voice Picking

Voice picking is the newest strategy for picking warehouses where the technological involvement is at its highest. Here, the warehouse picker has a device on his wrist and is provided with a headset where the orders or products that need to be picked are displayed on the wrist device, and they select the orders accordingly from the fulfillment facility.

Voice picking works well with other strategies as it facilitates data visibility for batch picking and reporting for zone methods. Therefore, voice picking is not only a strategy on its own but also helps in other strategies.

Combined Warehouse Picking Strategies

To refine warehouse picking, the supervisor may combine two or more order picking strategies. The combined warehouse picking strategies are stated as follows:

Zone-Batch Picking

A hybrid structure automatically gets created when batch picking and zone picking strategies are combined, in which the warehouse picker is responsible to carry out batch picking in a specified zone that is assigned to them. This hybrid structure works best when there is a large warehouse and is ideal when the client’s requirements include different kinds of orders.

Zone-Wave Picking

In zone wave picking, the large warehouse is divided into different zones and each of the warehouse order pickers is assigned to a different zone. Here, they use a wave picking strategy within the zone to fulfill the order requirements. The warehouse pickers follow the process of one order at a time in this method, within their zone.

Zone-Batch-Wave Picking

This is a relatively complex process that combines the two hybrid strategies; zone wave picking and zone batch picking, respectively. This method works best in a large fulfillment facility with different kinds of orders that are not similar. Here, each warehouse picker is assigned to a particular zone where they carry out their order fulfillment process using both the wave picking and batch picking strategies as and when required, as they have to collect multiple orders simultaneously.

Warehouse pickers pick several items according to the picklist by moving to and fro in the warehouse and then placing them in separate racks or containers where each container is associated with the individual orders. This method is beneficial in saving travel time. It also removes the need for sorting because the warehouse pickers do it themselves.

Multi-Batch Order Picking

The multi-batch order picking system works in a mechanical way where the warehouse picker picks multiple orders at a time to reduce the time of picking. In this method, the warehouse order picker generally uses huge picking carts with multiple tiers to move through the fulfillment facility and pick the desired products as per the picklist. This picking method is beneficial as it reduces the picking time and increases efficiency.

  7. Floor rackspace should be used for the pickers walking on foot whereas elevated racks can be used by the warehouse pickers who are on the order picking carts.
  8. Invest in radio frequency identification (RFI) for mapping the inventory location and position in your warehouse.
  9. Select the appropriate storage medium and space for your inventory according to the ordered products.

Automated Warehouse Picking Systems

Automated warehouse picking systems are based on modern-day technologies and are generally helpful for the warehouses that have been built in recent times. As discussed above, the voice picking system is one of the automated warehouse picking techniques introduced by technological changes and is mostly used in current warehouses.

Let’s explore some commonly used automated warehouse picking systems, apart from the voice picking system, which is stated as follows:

When the warehouse picker is picking the products as per the order list, they scan the barcode on the product, and all the relevant order details are mentioned there, with which they can differentiate and put the products on the racks and shelves accordingly.

Mobile Scanner Based Picking System

For this system to work, it is necessary to have a unique barcode on all the products in the warehouse facility. With this system, the accuracy of the order list will be fulfilled as the warehouse order picker will only pick those products on the picklist and scan the products according to the list. If the warehouse picker picks some product that is not on the list, then the mobile of the picker will buzz with a notification that this product is not on the list.

Collaborative Mobile Robots System

Recent times have seen increased use of robots in every field of work, especially in manual tasks. In warehouse picking as well, robots are used where they are controlled and function in such a way that they do all the manual tasks of picking the orders according to the order list. The human operators of the warehouse facility operate these robots to run to and fro in the warehouse to collect the orders according to the picklist. This system helps to save time and manual labor in the process.
