After visiting some 700 food processing facilities over the course of my career in the food industry, one of the most valuable programs I have seen these operations adopt is the 5S program. The concept was originally developed by the Japanese as a means for improving operational efficiencies, especially for ensuring just-in-time (JIT) manufacturing. In Japanese, the five S’s are: seiri, seiton, seiso, seiketsu and shitsuke.
