The order picking process is a fundamental part of any warehouse environment. It involves the selection and retrieval of products from a storage area, in preparation for shipment. The efficiency of order picking can affect a company's profitability, hence the importance of optimizing this process.
This blog will explore the order picking process, including the different methods used, and how technology has transformed this operation in recent years. We'll also look at some best practices to improve order picking accuracy and efficiency.
Order Picking Methods
There are several methods used in order picking, and the choice of method depends on factors such as the size of the warehouse, the type of products being picked, and the order volume. Here are the most common methods:
1. Piece Picking: this method involves selecting an individual item from a storage location, sometimes referred to as a "pick face." It is the most common picking method and is often used in warehouses with low order volumes.
2. Batch Picking: with this method, multiple orders are consolidated into one batch, and the picker retrieves all the required items in a single trip. The items are then sorted into individual orders at a packing station. Batch picking is suitable for warehouses with a high volume of small orders.
3. Zone Picking: in this method, the warehouse is divided into zones, and each picker is assigned a specific zone. The picker is responsible for retrieving items from that zone only, before passing them to the next picker in the sequence. Zone picking is particularly useful for large warehouses with a high order volume.
Order Picking Technology
The increased adoption of technology in warehouse operations has transformed the order picking process. Some of the technologies which have been implemented in recent years include:
1. Voice Picking: this technology involves the use of headsets and microphones which guide pickers through the order picking process. This method improves accuracy, as the picker is guided step-by-step, reducing the risk of errors.
2. Barcode Scanning: with barcode scanning, pickers scan a barcode on a product, which then communicates with the warehouse management system to confirm that the correct item has been picked.
3. Pick-to-Light: this method involves the use of lights mounted on shelves; when an item needs to be picked, the light above the shelf illuminates, guiding the picker to the correct location. Pick-to-light is particularly useful in warehouses with a high order volume.
Best Practices for Order Picking
To improve order picking efficiency and accuracy in your warehouse, here are some best practices to consider:
1. Order Consolidation: by consolidating orders, you can reduce the number of pick trips required. This is especially useful with batch picking.
2. Regular Audits: regular audits help to identify any discrepancies or errors in the order picking process. This allows you to make improvements and reduce the risk of errors.
3. Training: training your pickers to identify and report incorrect items can help to reduce the number of errors and improve efficiency.
4. Continual Improvement: by continuously reviewing and improving your order picking process, you can optimize efficiency, accuracy, and reduce costs.
Conclusion
The order picking process is a fundamental part of any warehouse operation. The choice of method depends on factors such as order volume, warehouse size, and product type. Implementing the right technology can improve efficiency and accuracy, while best practices such as order consolidation and regular audits can reduce errors and costs. By continually reviewing and improving your order picking process, you can optimize efficiency and improve profitability.
