As you study your warehousing operations, you should be able to identify every activity that absorb resources without creating additional value. The question that you all should ask to yourselves is how much more profitable could the warehouse be if we eliminated the errors or waste from the processes?
Poor utilization of space is a kind of waste. Space is money and it is paid for every month. If extra space is acquired when the existing warehouses are not utilized effectively, the waste is obvious.
Although staging of product at the shipping and receiving docks is accepted as a necessity today, could it be eliminated? Since warehousing is nothing more than the management of space and time, reducing waste starts with identifying the poor use of both.
Lean warehousing is the elimination of wasted space and wasted time with a systematic approach. It includes,
- Improved flow of material
- Better utilization of available cubic space
- Creation of perfect orders.
A warehouse adds value of time, place and quantity that is not available from the manufacturer or supplier. Most warehouses receive large, infrequent loads and deliver smaller loads more frequently.
Focus on FLOW
Material flow (MF) is the description of the transportation of raw materials, pre-fabricates, parts, components, integrated objects and finally products as a flow of entities.
Benefits after optimization of material flow
- Purchasing cost will decrease
- Quality of product will increase

- Product cost will decrease
- Customer satisfaction will increase
