What does Just in Sequence mean?
The term Just in Sequence (JIS) describes a delivery type in procurement logistics. The JIS process is a further development of just-in-time (JIT) delivery. The delivery of necessary materials for production is delivered in quantity and type as well as in sequence at the exact time required for production.
The procedure
In order to realize a smooth procurement according to Just in Sequence, to determine the demand and to minimize the effort in the supply chain, an electronic data exchange (EDI systems) and the communication between buyer and supplier is indispensable. A typical application area is the automotive industry. The automobile manufacturers operate this type of delivery to perfection.
Parts are delivered to the assembly line at the right time and in the correct sequence and position. There, the final assembly of the components to the waiting construction takes place immediately.
Just in Sequence production is oriented to the production cycle. This form of procurement logistics is only possible through excellent transport planning. Transport planning has the task of keeping inventory and transport costs as low as possible. Elementary features are the determination of the optimal quantity and calculation of the correct time of delivery in order not to interrupt continuous production.
Advantages of procurement logistics - Just in Sequence
- No inventory costs at receiver
- No stock at the consignee
- Delivery of the modules on the assembly line
- Minimum space required for mounting
- production-synchronous variants for final assembly
Disadvantages of procurement logistics - Just in Sequence
- high communication effort between customer and supplier
- high dependence on suppliers
- in case of complications, danger of production stoppage
Conclusion
If implemented consistently, the advantages for companies outweigh the disadvantages. The process minimizes capital commitment, warehousing is almost completely eliminated and goods are delivered at the right time to supply the vehicles in the pearl chain with the right modules.
