The Wal-Mart chains of [[supply]] are lengthy and [[fragile]].

The JIT inventory control of the [[retail]] and [[food distribution system]] is both [[interdependent]] and [[fragile]].

Wal-Mart is proof that we live in a fragile [[society]]. The kanban or "[[Just In Time]]" [[inventory]] system was developed in [[Japan]] and became popular in [[America]] starting in the 1970s. It is now ubiquitous in nearly every [[industry]]. The concept is simple: Through close coordination with subcontractors and piece part suppliers, a manufacturer can keep its parts inventory small. Kanban is a key element of lean [[manufacturing]]. Manufacturers order batches of parts only as needed, sometimes ordering as frequently as twice a week. Companies now hire Six Sigma consultants and Kaizen gurus, they buy sophisticated [[computer|data-processing]] systems, and they hire extra [[purchase|purchasing]] administrators, and these expenses actually save them [[money]] at the bottom line.

Just In Time inventory systems have several advantages: less [[warehouse]] space, less [[capital]] tied up in parts inventory, and less [[risk]] of parts obsolescence.
