Lean supply chains work best with products that sell in high volume and low variety (Christopher). The reason for this is clear when one considers a type of product meeting this criterion. Toilet paper sells in predictable volume and while there is some variety with this product, it is basically the same from brand to brand. The consumer is more likely to buy this product as a result of price rather than bells and whistles. A manager of a supply chain of toilet paper can use many tools to keep the logistics cost low. Sales of this product are likely to be tied to population size with little of no variation in sales except in college towns where TP sales may be higher during rush week. This consistency allows managers to ship regular orders of the product. Consistency allows for long-range contracts with shippers, which is less expensive. Consistency also allows for optimization of the production line. Regular production allows a manager to operate factories at near capacity with the right mix of automation to minimize fixed and variable costs.
The drawback to a lean supply chain is the long lead-time required to adapt to a change in demand. If a hurricane suddenly formed off the coast of Florida, and consumers suddenly began buying up survival products, like toilet paper, it may take
