The world's biggest chain of stores, [[Wal-Mart]], is proof that we live in a fragile [[society]]. The kanban or "[[just in time|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 purchasing administrators, and these expenses actually save them [[money]] at the bottom line. | The world's biggest chain of stores, [[Wal-Mart]], is proof that we live in a fragile [[society]].
