Just In Time (JIT) Manufacturing

A planning system for manufacturing processes that optimizes availability of material inventories at the manufacturing site to only what, when & how much is necessary.

Typically a JIT Mfg. avoids the conventional Conveyor Systems. JIT is a pull system where the product is pulled along to its finish, rather than the conventional mass production which is a push system. It is possible using various tools like KANBAN, ANDON & CELL LAYOUT.
Others tools include: shojinka, smed, jidoka, poka-yoka, and kaizen.
