Picking strategies
| Strategy | How it works | Typically suits |
|---|---|---|
| Batch picking | Several orders are picked in the same round and separated afterwards. | Many small orders with overlapping items. |
| Wave picking | Orders are grouped into planned waves, for example by cut-off, carrier, zone or priority. | Flows with several carrier departures or priorities. |
| Single-order picking | One order is picked at a time. | Larger or more complex orders that need their own handling. |
The right strategy depends on the order profile. A typical way to choose:
- Analyse the order profile (lines per order, units per line, channels).
- Measure pick frequency per SKU.
- Choose a strategy per order type.
- Test sorting and packing.
- Follow pick time and error rate.
Slotting – the right item in the right place
Slotting means placing each product in the right storage location based on how it is actually picked. A good layout cuts walking time and makes both normal operations and peak season easier to handle.
- Pick frequency – fast-moving SKUs are placed where they can be reached with shorter picking routes.
- Size and weight – physical properties determine the type of storage, ergonomics and safety.
- Season – locations may need to change when the pick frequency of the range shifts.
Typical slotting work: classify SKUs by movement, measure walking time, identify congested zones, move high-frequency items and follow the effect after relocation.
