You Might Have a Bad Warehouse If... You pick from "permanent" storage areas
This bad warehouse is brought to you courtesy of the esteemed Tom Speh, Senior Director of MBA Programs at Miami University. In this bad warehouse Tom witnessed order pickers going to the company's "permanent storage" location, at the farthest corners of the warehouse, to pick cases of product to fill shopping orders. The "permanent storage" area was "suppose" to be for product stored for longer than 90 days, but Tom saw order pickers repeatedly going to pull cases out of the pallets stored there.
If you catch your picking team going the distance (literally) to pick product from "permanent storage" areas, ask yourself just how efficient can it be to make repetitive carton picks from pallets meant to be in storage, instead of from picking locations.
How might this warehouse address their problem better? The Warehousing Education and Research Council advocates using a "Forward Pick Area" or "Picking Module" in a dedicated area specifically designed to enhance order picking operations. It may be something as simple as racks containing cartons (and possibly individual units if you ship that way), or it could be a flow rack area which may even utilize pick to light or voice picking technology. The pictures demonstrate an example of forward pick areas (on the left) and picking modules (on the right).
If you are space constrained and do not have room for a picking module, then at a minimum keep some of the slow moving items in the main warehouse as "primary location" and then replenish as needed from the more "permanent location". In this case consider using the lowest rack spaces down each aisle for storage of broken pallets and do carton picks from there, moving a full pallet down to that area as the cartons are consumed. Keeping the area used for picking cases low can also enhance performance through elimination of the constant rising and lowering of a lift.
Now a word on "permanent storage". If I had my way, I would permanently ban the term "permanent storage". Today's warehouse should focus on distribution and flow of product - not parking it somewhere permanently, even if "permanent" really means 90 days. It's perfectly OK to have more than one slot for your product - but a better and more common terminology is "primary" and "secondary" locations.
For those wanting to learn more about picking operations, we recommend the following resources:
- Read the sections on Slotting, Storage, and Picking and Packing Processes in the WERC "Warehousing & Fulfillment Process Benchmark & Best Practice Guide" available from the WERC Online Store.
- Review Tom Freese's discussion of Warehouse Layout and Design, available at the Freese & Associates website. This article gives a great overview of the basics on warehouse layout (FYI... he agrees with me on the idea of banning "permanent storage" locations)
I really love your feedback - and love you’re contributions to share those bad warehouse stories to help educate the profession on what NOT to do, and perhaps what to do if you’re not doing it.
