Just in sequence

Just in Sequence (JIS) is a further progression over Just In Time.

Not only are the parts used for production delivered just when they are needed, they are also delivered in the correct order, i.e. in the same sequence as the sequence of the manufacturing orders. JIS is in use predominantly in the automobile manufacturing. The respective control system is called sequence inlining system.

In Lean terms this means producing components in the order in which they were consumed. This can become important where inventory levels are low and production variability is low. Under these circumstances the oldest 'order' (or consumption) will be the first to need more of the component hence early replenishment is key to maintaining flow and low inventory.
