There are various types of pick and pack fulfilment. The process used in each warehouse will depend upon the amount of orders being fulfilled, the size of the space and the number of employees.
Piece Pick and Pack
This is the simplest of the four typesand involves each pick packer finding and collecting all of the items on their pick list and then moving onto the next order. This can be an effective process for small businesses, but is not often used in larger warehouses as one employee having to cover long distances to find all of the items themselves, one order at a time, can result in delays.
Batch Pick and Pack
This is similar to the previous type, however the employees will be dealing with multiple pick lists at once, meaning they can multi-task and be more efficient.
Zone Pick and Pack
In larger warehouses, zone pick and pack is often used because it decreases travel time between areas. Basically, employees stay in one area of the warehouse and only collect items that are in their zone. If orders contain items from multiple zones, the items are sent on once picked via conveyer belts, robots, tubes or other means.
Wave Pick and Pack
Like zone pick and pack, this type decreases travel times by making employees each cover only a specific area of the warehouse. The only difference here is that they will handle multiple lists – again with the aim of increasing efficiency and speeding up the process.
