Decrease inventories using the just-in-time supply chain process.
The limit of inventories reductions should not be set by financial indicators like capital or time in inventories but rather by the customer satisfaction on the time to deliver.
If the use of the "zero inventories" and "build-to-order" processes increase the "time to deliver" up to a full red "Customer Moving Away" index, reconsider rebuilding some stocks.
Beware specially with impulse buy products lile portable computers. Customers buy them when they see them, touch them and bring them back home immediately.
