As supply chain consultants, we are fortunate to be exposed to nearly every industry and have the unique opportunity to see hundreds of different warehousing and distribution operations. We get to see the different operations for exactly one reason: our clients want us to help improve them.
The most common item we recommend improving is the cleanliness and orderliness of a warehouse. Maintaining a clean and orderly operation is much more important than just the optics (though the optics are important - imagine taking a potential client or business partner through a dark warehouse with trash on the floor and graffiti on the wall!).
A clean and orderly operation drives the culture of accountability and effort. When nothing is disorganized or out of place, it makes it that much harder for someone to purposely misplace something or work inefficiently. When cleanliness is stressed, it follows to all aspects of the operation, from receiving to stretch-wrapping the pallet going out.
As simple as it sounds, this idea is not so simple to implement. Operators are typically evaluated on their productivity. The more you pick/put away accurately, the more productive you are. However, this leads to the little things being forgotten. Will an operator want to put an empty carton away in the corrugate bin if it slows them down? Probably not. These need to be taken into account when evaluating your warehouse personnel. Productivity is key, but not when it neglects other areas of the operation.
