Supply Chain Management Basics: Inventory Picking Strategies
- 2. Supply Chain Picking Basics • For most warehouse operations picking processes account for nearly 40-50% of total warehousing and distribution costs. For this reason alone, picking is a critical area of focus for supply chain operators. • Every 3PL, warehouse, distribution center, manufacturer or retailer operates differently and will require different picking strategies to help meet their specific business objectives. The most commonly utilized inventory picking strategiesinclude: • Batch picking • Wave picking • Cluster picking • Piece picking • Zone picking • Sortation picking
- 3. Single Order/Piece Picking • The most basic of picking strategies, piece picking, is the processof pulling inventory piece by piece for a single order. • This picking strategy is completed in a ratio of one warehouse picker to one customer order. 1 1
- 4. Batch Picking • Batch picking, also known as multi-order picking, is the process of pulling stock to fulfill multiple orders concurrently. Once all of the batched items have been picked, pickers will sort and stage orders accordingly. • This picking method helps to reduce travel time throughout the facility and number of trips taken, reducing the average pick cost per order. 1 2 31 2 3
- 5. Cluster Picking • Cluster picking is a similar process to batch picking in that warehouse staff pull inventory from multiple orders simultaneously, but rather than picking into one community container items are picked directly into their corresponding containers or totes. • This eliminates the additional labor required to separate orders at the staging/loading area. 1 2 3
- 6. Wave Picking • Wave picking, most typically facilitated by your warehouse management software, is a picking strategy where groupings of orders are released throughout the day in “waves”. • The timing of the these waves are scheduled to evenly distribute labor throughout the day. Average wave length can range anywhere from 1 to 4 hours, resulting in up to 8 waves per shift. • The variance in wave length and frequency is determined by the daily workload and available staff.
- 7. Zone Picking • Zone picking is an inventory picking strategy where warehouse staff pick solely from their designated zone. Depending on the size of the facility and staff availability zones can vary in size from a few grouped SKUs to full aisles. • Pickers will pull inventory from their designated zone to fulfill multiple customer orders. • This strategy is used to increase picking efficiency and allow for staff inventory handling specialization.

- 8. Sortation Picking • Sortation picking, a strategy reserved for facilities utilizing automated storage and retrieval systems (ASRS), requires little to movement for the order pickers. • Inventory is brought to the pickers via conveyor systems. This picking strategy reduces order fulfillment labor requirements with system automation. 1 2 3
- 9. Picking to Box • The pick to box strategy is used most often in warehouse facilities utilizing conveyor systems. In this strategy pickers remain at designated stations and place items in boxes as the conveyormoves them past. Each box may visit multiple stations before order fulfillment is complete.
- 10. Conclusion • Every order fulfillment operation will facilitate picking using a different picking method, combination of methods or a customized method to better fit their business. • It is critical to have knowledge of a variety of picking strategies dueto the constantly evolving supply chain and logisticsmarketplace. • Implementing the best picking method can help to reduce average order picking costs through improved efficiency, process optimization and labor reduction.
