In modern supply chain management, optimizing warehouse efficiency and outbound shipment processes is essential for meeting delivery targets and reducing operational overhead. Two advanced capabilities that significantly streamline these operations are the Two-Stage Picking process and Flexible Reservations, which include the innovative Pick by Choice feature.
Mastering Outbound Flow with Two-Stage Picking
Traditional single-stage picking involves retrieving parts from a warehouse and delivering them directly. However, as order volumes grow and fulfillment networks become increasingly complex, operations often require more structured, scalable handling methodologies. The Two-Stage Picking process divides the fulfillment workflow into two distinct steps to drastically improve organization, routing efficiency, and overall order accuracy.
Stage One: Retrieval and Transfer
In the first stage, parts are efficiently picked from their standard inventory locations using system-generated Pick Lists or Warehouse Tasks. Instead of moving directly to the loading dock, these items are transferred into a designated Shipment Location. This location functions as a strategic packing station or consolidation zone where goods are temporarily gathered before the final dispatch phase.
Stage Two: Consolidation and Packing
During the second stage, warehouse staff consolidate and pack the parts belonging to the same order. This critical step ensures that multipiece orders are unified prior to shipping, heavily reducing the risk of partial deliveries or misplaced parcels.
The Role of the Pre-Ship Delivery Note
The consolidation process is driven by the Pre-Ship Delivery Note, an incredibly versatile document that serves two vital purposes:
- 1. Packing List: It allows inventory staff to easily sort through all the material placed at the Shipment Location and pack the correct items together efficiently.
- 2. Delivery Document: It functions as the final delivery documentation that officially accompanies the goods during transport.
By decoupling the picking phase from the packing phase, modern warehouses can dynamically optimize forklift routes, reduce bottlenecks in high-traffic aisles, and ensure significantly higher order accuracy before a package ever leaves the facility.
Overcoming Rigid Workflows with Pick by Choice and Flexible Reservations
Historically, material reservations in warehouse management systems (WMS) have been overly strict. They frequently forced warehouse staff to pick exactly what the system reserved down to the most granular detail — including the specific lot, batch, serial number, or revision.
This rigidity often resulted in localized inefficiencies. For instance, if a reserved item was located in deep storage or temporarily obstructed, workers wasted valuable time searching for it, even if identical, perfectly acceptable parts were readily available in a more accessible bin. Furthermore, stock that contained reserved items could not be easily moved to restructure the warehouse, causing cascading delays in inventory management.
The Solution: Pick by Choice
To solve these physical and systematic constraints, modern logistics solutions introduce Flexible Reservations and the Pick by Choice feature. Pick by Choice empowers warehouse floor staff by treating the system’s material reservation as an optimized suggestion rather than a strict, unbreakable mandate.
While the item picked must absolutely correspond to the correct customer order line, the worker no longer has to perfectly match the original reservation on the pick list. If a worker cannot find the exact reserved item, Pick by Choice allows them to easily select parts from:
- Alternative storage locations
- Different available lots or batches
- Alternative serial numbers
- Different handling units
When an alternative item is selected, the system automatically adapts to the physical reality of the warehouse in real time. It seamlessly un-reserves the old stock and instantly reserves the new stock that the user intends to pick.
Systematic Integrity and Ad-Hoc Flexibility
This automated background processing is a game-changer. It ensures that count variances are prevented and inventory accuracy is perfectly maintained, all without disrupting the natural physical workflow or requiring tedious manual system overrides by floor managers.
Furthermore, Flexible Reservations allow supply chain managers to execute ad-hoc stock movements — such as transferring goods from overflow buffer zones to active picking locations — even if that stock currently includes reserved material. By uncoupling the physical location constraint from the soft reservation, the warehouse remains highly fluid and adaptable.
