What is the value of installing a pick module? Consider how order fulfillment works in companies not using pick modules compared to those who do use pick modules.
Here is a typical warehouse situation without the benefit of a pick module:
An order comes in. Pickers receive their instructions and immediately trek into the warehouse to fill their order sheets. This frequently requires walking [miles] all over the warehouse and costing precious time to find the items. Time is money, so the longer the picking process takes, the more it costs to fill the order.
Time constraints not only add to expense, they also increase the likelihood of errors.
Most companies require pickers to locate and pick items for an order within specified time limits. For example, a company might determine it should take picker 20 minutes to fill an order sheet. Any additional time over the 20-minute limit will result in extra cost and work against incentives the picker may have to earn more. As a result, the picker could rush to meet the time limit and accidentally pick wrong items. The picker may have saved the company money by not exceeding the time limit, but cost the company because the order is wrong.
Pick modules reduce these issues. Pickers working at a warehouse having a pick module save time, money and are less likely to make errors. Forklifts bring pallet loads of the items to pick directly to the pick module, drastically reducing the distance pickers must travel to find items on their order sheets. The pallet loads are broken down to carton-size quantities on one level and sent to another level where pickers access items, fill the order and send it to shipping where it is loaded for shipment to customers.
The result is a process that is more accurate, confined to a smaller area and faster.
